Applications

This compact line array speaker system consists of a bass speaker unit and four mid-high-range speaker units. It is designed for professional PA music applications at events of medium size and supplies a maximum total power of 1000 W.] The bass speaker unit provides an amplifier for the two bass speakers and another amplifier for the mid-high-range speaker units to be connected. A digital signal processor (DSP) is connected] ahead of the amplifiers. On the one hand, this processor serves for splitting the signal to the two amplifiers, on the other hand, it offers versatile possibilities for equalizing the frequency response, readjusting the delay time, and limiting the dynamic range. The DSP configuration is modified with the supplied software via a PC.  The L-RAY speaker system can be ground stacked or mounted in a suspended way (flown). It may be extended to a maximum of four systems mounted to each other. It is supplied with speaker cables for connecting the speaker units and mounting material for the suspended mounting.

Line arrays

Single speakers act similarly to point sound sources when dispersing the sound. Their sound radiation is spherical and the sound pressure level is reduced by 6 dB when doubling the distance to the sound source. For PA application of larger venues, this means that the volume at the stage must already have a very high level so that there will still be sufficient sound at a distance. If an infinite number of speakers is used which are arranged one above the other and if their distance between each other is relatively small regarding the wavelength of the frequencies to be radiated (coherent coupling), these speakers act together like a line sound source. The sound radiation of a line source is cylindrical and the sound pressure level is only reduced by 3 dB when doubling the distance to the sound source.

This effect is used for a line array speaker system. As of course, only a finite number of speakers can be used, the sound radiation only acts in a certain PA range similar to a line source. The more speakers are combined, the more powerful is the effect. The advantage of such a speaker system is a larger range compared to standard systems, i. e. less power is required and the volume at the stage can be lower, which will also protect the hearing of the audience close to the stage. In addition, disturbing interference will be prevented by the close vertical speaker arrangement. This occurs when several speaker systems are grouped horizontally (clustered) which is common and leads to phase extinction and uneven sound dispersion in the PA range. As the splay angle between the single elements of a line array can be adjusted individually, all speakers can be arranged in a curving way so that an even sound field for the respective auditorium is reached.

Installation

WARNING

• Installations that are not made in an expert way are a potential danger, especially if systems are flown above persons. Therefore, the installation must only be made by expert personnel familiar with the valid standards and safety regulations.
• The installation, especially the stability of the mounting connections, must be checked accordingly at regular intervals.

Installation of a single system

Mounting

1. For flying (suspending,fig. 3) the system, tightly screw the four ring bolts (13) in the threads on the upper side of the flight frame (14). Safely suspend the flight frame from all four ring bolts. The system can also be ground-stacked (fig. 4): Instead of the ring bolts, tightly screw the rubber feet to the frame and place the frame on safe ground. The indications of direction “above” and “below” used in the following descriptions refer to the suspended mounting and have to be replaced accordingly for ground stacking.
2. Place the vertical mounting rails at the edges of the bass speaker unit (15) onto the four connecting plates that stick out from the flight frame (14) and tighten them with four ball lock bolts.
3. Press the pin to unlock the bolt, put the bolt through the drill holes up to the stop, and then release the pin. Always check the connection and make sure that the bolt cannot be removed without unlocking.
4. Use two ball lock bolts (16) to connect the front side of the first of the four mid-high range speaker units (17) to the bass speaker unit.
5. As shown in fig. 2, connect the rear side of the upper mid-high range speaker to the mounting profile (18) on the bass speaker unit by means of a hexagon socket screw, two ball lock bolts, and the connecting plate (19).
6. Connect the other mid-high range speakers at the front side with each other, using two\ ball lock bolts for each connection.
7. Connect the mid-high-range speaker units with each other at the rear side. A curved form of the speaker system may be useful to achieve an even sound distribution. For this purpose, the angles between the mid-high range speaker units can be adjusted individually: As shown in the lower detailed view of fig. 2, attach the connecting plate
8. to the lower mid-high range speaker, using a hexagon socket screw. Attach the connecting plate to the upper mid-high range unit, using a ball lock bolt; select the appropriate drill holes to set the desired angle between the two mid-high range speakers.

Connection

1. As a signal source, connect an audio unit with line output (e. g. mixer, preamplifier, etc.) to the XLR jack LINE INPUT (12). The XLR jacks are balanced, but they may be connected in an unbalanced way via corresponding adapters.
2. The input signal for routing is available at the output LINE OUTPUT (11). Here, further amplifier systems for additional PA applications may be connected (compare chapter 4.2.2).
3. Connect the jack IN on the rear side of the first mid-high range speaker unit to one of the jacks MID / HIGH OUTPUT (4) of the bass speaker unit. Connect the plugs to the corresponding jacks and turn them clockwise until they lock. To remove the plug, pull back the safety latch on the plug and turn the plug counterclockwise.
4. Connect the jack OUT on the rear side of the first mid-high-range speaker unit to the jack IN of the next mid-high-range speaker unit. Connect the second mid-high-range speaker unit to the third and the third to the fourth in the same way.
5. If desired, connect a data line from a PC, depending on the kind of interface used, to the jack USB (7), RS-232 (8), or RS-485 INPUT (5). The RS-485 input signal is available at the jack RS-485 OUTPUT (6) for routing it to another system (compare chapter 6).
6. Insert the blue Powercon plug of the mains cable supplied into the Powercon jack (3) and then turn it clockwise until it locks. (To disconnect the cable from the unit, pull back the safety latch on the plug, turn the plug counter-clockwise and remove the plug from the jack.) Then connect the mains plug of the cable to a mains socket (230 V/ 50 Hz). Important: Never connect or disconnect a Powercon plug while voltage is applied. Always make the Powercon connection before making the mains connection. When disconnecting, always disconnect the mains connection before disconnecting the Powercon connection. Make sure that the current circuit to which the unit is connected is protected by a fuse with the appropriate current rating.

Combination of several

• L-RAY/1000 units For PA applications of larger areas, several L-RAY/ 1000 units may be combined. Up to four systems may be mounted with each other (fig. 6).

Mounting

1. For flying (suspending) the system, tightly screw in the four ring bolts (13) in the threads on the upper side of the flight frame (14). Safely suspend the flight frame from all four ring bolts. The system can also be ground-stacked (fig. 4): Instead of the ring bolts, tightly screw the rubber feet to the frame and place the frame on safe ground. The indications of direction “above” and “below” used in the following descriptions refer to the suspended mounting and have to be exchanged accordingly for ground stacking.
2. Place the vertical mounting rails at the edges of the first bass speaker unit (15) onto the four connecting plates that stick out of the flight frame (14) and tighten them with four ball lock bolts. Press the pin to unlock the bolt, put the bolt through the drill holes up to the stop, and then release the pin. Always check the connection and make sure that the bolt cannot be removed without unlocking. Remove the mounting profile (18) on the lower side of the bass speaker unit by releasing the screws.
3. Connect the bass speaker unit of the second system to the first bass speaker system, using four ball lock bolts. To add further systems, remove the mounting profile from this bass speaker unit as well and mount the next bass speaker units to this bass speaker unit in the same way.
4. Use two ball lock bolts (16) to connect the front side of the first mid-high-range speaker unit to the lowest bass speaker unit.
5. As shown in fig. 2, connect the rear side of the upper mid-high range speaker to the mounting profile (18) on the bass speaker unit by means of a hexagon socket screw, two ball lock bolts, and the connecting plate (19).
6. Connect the other mid-high-range speakers at the front side with each other, using two ball lock bolts for each connection.
7. Connect the mid-high-range speaker units with each other at the rear side. A curved form of the speaker system may be useful to achieve an even sound distribution. For this purpose, the angles between the mid-high range speaker units can be adjusted individually: As shown in the lower detailed view of fig. 2, attach the connecting plate (20) to the lower mid-high range speaker, using a hexagon screw socket. Attach the connecting plate to the upper mid-high range unit, using a ball lock bolt; select the appropriate drill holes to set the desired angle between the two mid-high range speakers.

Connection

1. As a signal source, connect an audio unit with line output (e. g. mixer, preamplifier, etc.) to the XLR jack LINE INPUT (12) of the first bass speaker unit. The XLR jacks are balanced, but they may be connected in an unbalanced way via corresponding adapters.

2. Connect the output LINE OUTPUT (11) of the first bass speaker unit to the LINE INPUT (12) of the second bass speaker unit. Connect the LINE OUTPUT of the second bass speaker unit to the input of another bass speaker unit until all bass speaker units are connected.

3. Connect the jack IN on the rear side of the first mid-high range speaker unit to one of the jacks MID / HIGH OUTPUT (4) of the first bass speaker unit.  Connect the plugs to the corresponding jacks and turn them clockwise until they lock.  To remove the plug, pull back the safety latch on the plug and turn the plug counterclockwise.

4. Connect the jack OUT on the rear side of the first mid-high-range speaker unit to the jack IN of the next mid-high-range speaker unit. Connect the second mid-high-range speaker unit to the third and the third to the fourth in the same way.

5. As described in steps 3 and 4, also connect the other bass speaker units to one mid-high range speaker unit each and this unit to three further units as a maximum.
   Important: Never connect more than four mid-high range speaker units to one bass speaker unit, otherwise the bass speaker unit will be overloaded!

6. If desired, connect a data line from a PC to the jack USB (7), RS-232 (8), or RS-485 INPUT (5) of the first bass speaker unit. For the combination of several systems, a connection via RS-485 is recommended as the signal can be fed via the jack RS-485 OUTPUT (6) to the jack RS-485 INPUT of the respectively next bass speaker unit (compare chapter 6). The output RS-485 OUTPUT of the last bass speaker unit of the chain should be terminated with a 120 Ω resistor, especially if longer control cables are used. Solder the resistor (> 0.3 W) to pins 2 and 3 of an XLR inline jack and connect the inline jack to the RS-485 output, or use a corresponding terminating plug (e. g. DLT-123) with adapter (inline jack – inline jack, e. g. NTA-113).
   Note: If the L-RAY system is connected both to a computer and to units that are earthed via the mains cable (e. g. mixer), hum interference may occur due to ground loops. To eliminate this interference, the audio connection may be led via a ground isolator (e. g. FGA-202).

7. For the power supply, connect the units via the Powercon jack (3) to the 230 V mains (chapter 4.1.2, step 6).

Operation

1. Switch on the signal source connected.
2. Switch on the PA system with the mains switch POWER (1) on the rear side of each bass speaker unit. The switch lights up to indicate operation.
3. Adjust the volume with the control LEVEL and, when using several systems, adjust the volume ratio of the systems with each other. [The volume can also be changed via the remote control option of the signal processor (chapter 6.5).] If the LED PEAK (10) lights up, the input level is too high; turn back the control correspondingly.

CAUTION: Never adjust a very high volume. Permanent high volumes may damage your hearing! The human ear will get accustomed to high volumes which do not seem to be that high anymore after some time. Therefore, do not further increase the high volume after getting used to it.

Adjustment of the Signal Processor

The bass speaker unit is equipped with a digital signal processor (DSP). On the one hand, this processor serves for splitting the signal to the bass speakers and the mid-high range speaker unit, on the other hand, it offers versatile possibilities for equalizing the frequency response, readjusting the delay time, and limiting the dynamic range. Due to its factory configuration, the DSP is ready for operation. For modifying the adjustments, e. g. for adapting the system to the room acoustics, the supplied PC software and three different interfaces can be used to connect a PC: USB (7), RS-232 (8), RS-485 (5 and 6). The control via RS-485 has clear advantages compared to the other two interfaces: Much longer cables are possible and the connection can each be fed through via the jack RS-485 OUTPUT (6) to the RS-485 INPUT (5) of the next system.

As it is possible to name the systems individually, up to 10 systems may be configured separately via the same data bus by the control program.

Installation of the PC software

The system requirement for the installation of the supplied control program is a PC with the operating system Windows 98 SE or higher and a USB, RS-232, or RS-484 interface. The minimum screen resolution should be 1024 × 768 pixels. For the installation of the PC software, start the installation program “Active Speaker Controller […] .msi” on the supplied CD and follow the instructions of the installation program.

Installation of the USB driver

A special driver is required for the connection via the USB interface. This is available on the supplied CD. The search path for the driver is requested in the installation dialogue which appears on the screen after connecting to the USB interface. Then select the directory DRIVER on the CD. The matching driver is then automatically installed.

Establishing the data connection

Control of several systems via the RS-485 data bus

For controlling several L-RAY systems via the RS-485 data bus, each system must first be provided with a name and an individual ID number. This is only necessary for the first operation. The systems memorize these data and can thus be addressed separately. If the designation has already been made, the connection set-up can be started with step 9).

1. Separate all data connections between the systems.
2. Connect the first system via RS-485, RS-232, or USB to the PC. Start the program “Active Speaker Controller”.
3. Call the menu item “Communications Enable Communications”. The program looks for a connected L-RAY system and shows the system found in the list under “Select Device:” and the current number and the current name of this system under “Current Device Information”.
4. Start the connection set-up by clicking “Connect”. (At this moment it is of no importance which option has been selected under “Data Configuration”.)
5. After the connection has been established and the data have been read by the system (“-> Program Data Transferred OK…” appears in the status line below), call the menu item “Device Edit Current Device Information”. The window “Edit current device information” with the current ID number and the current name of the connected system is shown.
6. Enter a unique ID number (1 – 10) and a significant name (a maximum of 14 characters of the ASCII set of characters) for the system into the corresponding field and confirm with “OK”. The data are transferred to the system and shown as “Current Device ID” and “Current Device Name” in the main window on the top right.
7. Separate the connection via the menu item “Communications Disable Communications”. “-> Disconnected” appears in the status line.
8. Remove the connection cable from the connected system and connect it to the next system. Repeat steps 3) to 8) until all systems are clearly named. Then connect the systems with each other again and the first system to the PC.
9. Call the menu item “Communications Enable Communications”. Now all systems connected appear in the list under “Select Device:”. Select the system to be configured and then the direction of the data transfer “Data Configuration”: “Upload Program Data from Device”: The current data from the L-RAY system (start setting) are transferred to the PC. This option is preset and should also be used for the first operation. “Download Program Data to Device”: The settings on the PC are transferred to the L-RAY system. This option is useful if data have already been loaded from a file or another L-RAY system. Start the connection set-up by clicking “Connect”. With the key “Esc” or by closing the dialogue window the process can be stopped without connection set-up.

Control of individual systems

For connecting only a single system to the PC at a time, even if several systems are used:

1. Connect this system via RS-485, RS-232, or USB to the PC. Start the program “Active Speaker Controller”.
2. Call the menu item “Communications Enable Communications”. The program looks for a connected L-RAY system and shows the system found in the list under “Select Device:” and the current number and the current name of this system under “Current Device Information”. The differentiation of several systems by means of the number registered here is of no importance to the data transfer as long as the units are not to be connected via a common data bus.
3. Select the direction of the data transfer “Data Configuration”:

“Upload Program Data from Device”: The current data from the L-RAY system (start setting) are transferred to the PC. This option is preset and should also be used for the first operation. “Download Program Data to Device”: The settings on the PC are transferred to the L-RAY system. This option is useful if data have already been loaded from a file or another L-RAY system. Start the connection set-up by clicking “Connect”. With the key “Esc” or by closing the dialogue window the process can be stopped without connection set-up. To separate the connection later, call the menu item “Communications Disable Communications”.

Note: In exceptional cases, the installed program may be aborted after its start. This may happen when another device has been assigned to the serial COM port 3. For data communication, the program “Active Speaker Controller” expects COM port 3 to be free. To make COM port 3 available, it is recommended to assign the other device to a different COM port, if possible [e. g. under: Control Panel /Administrative Tools / Computer Management / Device Manager / Ports (COM and LPT)].

Calling memorized adjustments

In the EEPROM of the signal processor six different adjustments “Program” can be memorized which are maintained even after disconnecting the power supply. To call an adjustment memorized before in the EEPROM of the signal processor:

1. Call the menu item “Program List Program & Recall”. The window “List Program” opens and shows the list with the six adjustments memorized in the EEPROM of the signal processor.
2. Click the button “Recall” next to the desired program. The signal processor switches to the selected program and the data of the adjustment are transferred to the PC and are displayed.

If none of the programs shown is to be called, close the window with the mouse or press the key “Esc”. The memorized adjustment “Current Program” last called is automatically active when switching on the L-RAY system (start setting).

Modifying the adjustment

Attention

• In connection with the control program, a signal processor is an effective tool that allows for making very fine but also substantial modifications of the characteristics of the speaker system.
• Any modification of the parameters should therefore be made with caution and special knowledge. Extreme modifications of the adjustments may at the worst damage the speaker system.

When the PC and the L-RAY system are connected, modifications of parameters on the PC are immediately transferred to the L-RAY system. However, they are only memorized in the RAM of the signal processor and are not kept after switching off the L-RAY system. To keep the adjustments permanently, they must be memorized in the EEPROM of the signal processor (chapter 6.6). In the main window of the program, the signal way through the amplifier system is shown as a block diagram (fig. 7). From the input on the left side, the signal passes through the blocks PEQ and LEVEL first and is then split to the two output branch es LOW and HIGH. The LOW signal is fed to the amplifier of the bass speakers, and the HIGH signal to the amplifier for the mid-high-range speaker units. When clicking the function blocks, the window below the block diagram shows the corresponding adjustments. The adjusting possibilities of the different function blocks are explained in the following:

PEQ

In these function blocks, 6 or 2 (at the input) independent filters to be combined are available. By clicking the number of the filter select the filter to be configured. The selected number is shown in red. The type of the filter can be selected from the list under “Type:”:

None: The filter is deactivated

Peaking

The filter curve has the shape of a bell, the following parameters can be adjusted

• Frequency: center frequency Q-factor (bandwidth)
• Level: boosting or attenuation of level

Bandpass

In a band-pass filter with level attenuation above and below the center frequency, the following parameters can be adjusted

• Frequency: center frequency Q-factor (bandwidth)

Hi-Shelf

Boosting or attenuation of all frequencies above the limit frequency, the following parameters can be adjusted

• Frequency: limit frequency
• Level:  boosting or attenuation of level

Lo-Shelf

Boosting or attenuation of all frequencies below the limit frequency, the following parameters can be adjusted

• Frequency: limit frequency
• Level: boosting or attenuation of level

Notch

Maximum attenuation of a selected frequency, the following parameters can be adjusted

• Frequency: center frequency Q-factor (bandwidth)

The adjustment of the selected filter and the curve resulting from all filter adjustments are shown in the frequency diagram.

HPF / LPF

These function blocks, each with one high pass filter and one low pass filter, primarily serve as a cross-over network to split the signal between the bass speakers (LOW) and the mid-high range speakers (HIGH). Thus, the filters available here ensure that the speakers only receive the signal parts they are specialized to reproduce. Therefore, the presetting of these filters should be modified with caution! It is possible to select from the list under “Filter Type:” from various filter characteristics (Butterworth, Bessel, Linkwitz- Riley) with different slopes. The respective limit frequency is adjusted under “Frequency”. A low pass filter is deactivated by setting its limit frequency to the maximum (“Off” is shown under “Frequency”). A high pass filter is deactivated by setting its limit frequency to the minimum (“Off” is shown under “Frequency”). The pass-through characteristics of the filter setting are shown in the frequency diagram.

LEVEL

The level for the input signal or for each of the output signals HIGH and LOW can be adjusted in these function blocks. The phase can additionally be selected in the function blocks of the two output branches:

• Normal: output signal and input signal have the same phase
• Inverse: compared to the input signal, the output signal is inverted

DELAY

This function block is available for both outputs. Here a signal delay “Delay Time” can be selected in milliseconds e. g. to readjust the differences in delay time for different speaker distances. Below the input field for the delay, the calculated distance is shown in meters as well as in feet and inches according to the delay time of the sound. Direct input of the distance with automatic calculation of the delay time is also possible.

COMPRESSOR & LIMITER

For limiting the dynamic range the following parameters in this function block can be adjusted together for both outputs:

• Threshold: value from which the reduction of the amplification starts

The ratio is the ratio by which the amplification is reduced (e. g. the adjustment 9 1 means that with a level increase of 9 dB, only an increase of 1 dB will be admitted). With a high compression ratio (20: 1 or higher) and a short response time ad just (attack time = 1 ms or less), a limiting effect will be reached.

• Release Time: time that has to pass after dropping below a threshold value until the amplification has regained its standard value.
• Attack Time: the response time which defines how quickly the unit responds to the threshold value exceeded by reducing the amplification.

The Attack Time and the Release Time should not be too short. In case the threshold value is exceeded for a longer period of time, quick, permanent readjusting will lead to audible distortions.

Memorizing the adjustment in the EEPROM of the signal processor

In order to make adjustments permanently available in the EEPROM of the signal processor:

1. Call the menu item “Program Save As Current Program in Device”.
2. Select the memory location “No. 1” up to “No. 6” and confirm. Thus, an adjustment memorized here before is overwritten. The adjustment is first memorized under the name of the adjustment “Current Program Name” last called and can then be renamed (chapter 6.7).

This memorized adjustment is now also considered a “Current Program”, i. e. it is automatically active when switching on the L-RAY system the next time (start setting).

Renaming an adjustment in the EEPROM of the signal processor

To rename the adjustment “Current Program” called at present

1. Call the menu item “Program Edit Current Program Name”.
2. Enter the new name and confirm. The name is immediately modified in the memory location last selected in the EEPROM of the signal processor.

Memorizing the adjustment in a file

To memorize the current adjustment in a file on the PC (e. g. for later use or to use it for another L-RAY system):

1. Call the menu item “File Save as …”.
2. Enter the file name and select the location of the storage and confirm. The file name can be selected independently of the name of the adjustment.

The file name is automatically completed by the extension “.asc”. The name of the adjustment selected at present is also memorized in the file. For memorizing the adjustment with another name in the file without modifying the name in the EEPROM of the signal processor, proceed as follows:

1. Separate the data connection to the L-RAY system with the menu command “Communications  Disable Communications”.
2.  Call the menu item “Program Edit Current Program Name”.
3. Enter the name to be memorized in the file and confirm.
4. Call the menu item “File Save as …”.
5. Enter the file name and select the location of the storage and confirm.

Loading an adjustment from a file

To load an adjustment from a file, no data connection must exist.

1. If required, separate the data connection to the L-RAY system with the menu command “Communications Disable Communications”.
2. Call the menu item “File Open”.
3. Select the desired file and confirm.
4. The name of the adjustment can now be viewed via the menu item “Program Edit Current Program Name” and modified, if required.
5. Call the menu item “Communications Enable Communications”. The program looks for L-RAY systems connected.
6. If several L-RAY systems have been found, select the desired system in the list “Select Device:”.
7. Under “Data Configuration” select the option “Download Program Data To Device”.
8. Click “Connect”. The data connection to the L-RAY system selected is set up and the adjustments are transferred into the RAM of the signal processor. The name of the adjustment loaded from the file now appears behind “Current Program Name:” in the upper part of the main window. For permanent storage of the adjustments in the EEPROM of the signal processor call the menu item “Program Save As Current Program in Device” (chapter 6.6).

Reset the signal processor to factory setting

Attention: This function cancels the memory location selected at present in the EEPROM of the signal processor irreversibly and overwrites it with the factory setting.

1. A data connection must exist. If not, establish it via the menu item “Communications Enable Communications” (compare chapter 6.3).
2. Call the menu item “Program Load default setting”.
3. Confirm the safety request. The factory settings are loaded from the file “factory default.asc” written into the same directory during installation as the program file. The data are immediately transferred to the L-RAY system and written into the EEPROM of the signal processor under the number selected at present.

Modifying the name of an L-RAY system

To modify the name of an L-RAY system to which a data connection exists at present:

1. Call the menu item “Device Edit Current Device Information”.
2. Enter a significant name (a maximum of 14 characters from the ASCII set of characters) and, for controlling several systems via the same data bus, a definite ID number (1 – 10) for the system into the corresponding field and confirm. The data are transferred to the system and are displayed as “Current Device Name” and “Current Device ID” in the main window on the top right.
