System Operation

4W-1 KU Receiver

Buttons Function
The Power Button (1) is used to turn ON or OFF all four receivers at the same time. When this power button is pressed for two seconds, the blue backlights on the LCD Displays (8) will light up indicating the receivers are on. Press the Power button again for two seconds to turn off the receivers. The backlight on the LCD will display “OFF” indicating the receivers are off. At power-off the 4W-1 KU QUAD receivers will store the last settings entered and re-display them at power-on. It can be reprogrammed to any new Group/Channel, or Volume level. The default factory setting is Group 00 (Receiver 1) and 03 (Receiver 2), 06 (Receiver 3) and 09 (Receiver 4), Channel 00 and Volume 63 are same for all receivers. The …a.. (Up) or,., (Down) Buttons (7) are active while in the Set mode, or can be used to change Volume Level (11) at anytime.
When the Set Button (6) is repeatedly pressed the LCD Display (8) menus will cycle in the following order:
flRIN flEl’/U > l)OLUflE > GROUP > [HRNl’IEL > flRIN flENU (repeats)

During manual programming, the selected function will flash for five seconds or press the Set button to confirm the selection and the display will return to the main menu.
The AUTO-SCAN/ ASC (IR Sync) Button (2) has two functions:

  • Long press (hold ~2 seconds) for AUTO­SCAN for finding a clear channel within the frequency band (with all TXs turned off at this time). Clockwise running segments on the LCD display show the scanning
    is in progress which normally takes ten seconds. When it finds an interference­free channel, it will display and store that channel for use. Then ASC IR Sync the TX as described below.

  • Short press (~ 1 second) to transfer the selected frequency information from the receiver to the transmitter for easy synchronization prior the transmitter can be used. When short pressing the ASC IR Sync button while the main menu is displayed, the IR LED (4) will light up red and stay for about three seconds. This indicates IR transmission is in progress and IR data is transferring during this period. A transmitter should be usedat this time to receive data from the receiver (see IR Sync Programming in Programming sections of HT-1 KU andBT-1 KU transmitter sections). Upon successful data transfer (usually in about three seconds) the IR LED stops and the transmitter’s backlight will light up and the transmitter will transmit a radio signal on the same channel as the receiver. The Signal Strength and Diversity Indicators on the receiver’s LCD display will then light up, indicating that the IR link is completed. If manual channel selection is preferred, skip this selection.

Selecting the 4W-1 KU QUAD ReceiverVolume Level/ Group/ Channel
This section will also aid in finding desired channel(s) of operation when setting up your system(s). Press the Set Button (6) three times to check the current Volume Levels (12) setting.

To change the Volume Levels, press the ….. (Up) or…, (Down) Buttons (7) anytime for single stepping, or hold the Up/Down button
continuously for faster level selection. Select 1 of 63 (soft to loud sound) levels from the Volume menu and advance to exit Setup Mode by pressing the Set Button one more time. Selecting O should mute the receiver and no output for the Line Out only. The XLR out is unaffected.

Choose the 4W-1 KU QUAD operating frequency by selecting one of ten Groups (9) and one of 100 Channels (10) that are determined to be desirable open channels. Press the Set button to enter the Group setup mode and the Group icon will flash, then press the Up/Down button once for single stepping through the groups, or hold continuously for faster group selection. Select 1 of 10 groups available from the Group menu and then press the Set button again to Channel Setup Mode and the Channel icon will flash, or press the Set button three times to skip changing the Channel or Volume.

Within the Channel Setup menu, press the Up/Down button once for single- stepping through the channels, or hold continuously for faster channel selection. Select 1 of 100 channels available from the Channel menu or press the Set button twice to skip Volume Level setting and exit to main menu. During manual programming, the selected function will flash for five seconds or press the Set button to confirm the selection and the display will return to the main menu. For detail how to IR Sync the TX, see IR Sync Programming in Programming sections of HT-1 KU and BT-1 KU transmitter sections.

Rack-mounting the Receiver

The Nady 4W-1KU QUAD receiver wireless system has built-In Rack Ears (13). Use the supplied screws to install the receiver onto the rack.

Note: Do not mount the receiver on a rack directly above an amplifier or other source of high heat. This could degrade the performance of the 4W-1KU QUAD. Always ensure adequate airflow and heat dissipation in any ra ck conf iguration .

__ Installing Antennas

Install antennas by connecting the two Antennas (21) included with your system onto the two RF Connectors (14/19) located on the back of the 4W-1KU QUAD receiver.

The two antennas must be installed in order for the diversity circuit to work properly.

The optimal positions of the antennas are 45° from the receiver and 90° from each other. For maximum range, it is always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.

To install optional Antenna Extension Cables (13a), insert one end of each cable into a rack hole and secure using the removable nut. Clip the other end of the cable to an RF Connector (14/19) on the back of the unit. Connect the two antennas to the front of the system.

Powering the Receivers

To power the receivers, plug the provided AC/DC Power Supply (20) adapter into the DC Input Jack (18) on the back of the receivers, then plug the adapter into an AC outlet.

Note: Any 16-1 BVDC source with a minimum 800-1 000mA capacity can also be used.

Once the receiver is connected to the power source, press the Power Button (1) for two seconds. The LCD Displays (8) will light (showing Group, Channel, RF Level Meter, and Output Volume). The Diversity A/B (2) and the AF PEAK LED (3) are off at this time and will display when the transmitter is on and the audio is transmitted. To turn off, press the Power button for two seconds. The LCD will display “OFF” then the backlight will turn off indicating the receivers are off.

Connect either the ¼” Unbalanced Audio Out (17) or each XLR Balanced Mic Outs (15) to your mixing board, effect, or amplifier inputs (See Connecting the Audio Outputs section).

Adjusting Squelch

In normal operation, each 4W-1 KU QUAD receiver’s Mute Control (16) works independently and should be adjusted clockwise (CW) to the minimum RF squelch setting at which the RF Level Meter (12) and one of the LED Diversity A/B Indicators (2) will remain on while your transmitter is in normal use, up to the maximum range anticipated in use for your application. However, in areas of high RF activity, the MUTE control may need to be adjusted counterclockwise (CCW). If the transmitter is off, the receiver signal and the RF Signal Meter (12) and one of the LED Diversity A/B Indicators is flickering or stay on continuously, the MUTE level should be adjusted higher level CCW (counterclockwise for less mute sensitivity level) to stop the flickering. Be careful not to adjust too high CCW setting as this may reduce the operating range to below what is needed. A range walk test will in selecting the proper level. If the range is not critical, note that a counterclockwise (maximum mute) setting will also yield a quieter mute function, which might be desired in certain applications. The MUTE level is factory preset at clockwise (CW) for maximum sensitivity and operating range (i.e. clockwise (CW) for minimum squelch level-maximum usable range).

Level and Peak LED Indicator

4W-1 KU QUAD receiver has an AF Peak LED (3) display for each receiver and each works independently per channel. The AF Peak LED occasional flickering green on normal or inputs to the transmitter is normal. If the AF Peak LED lights green continuously, you might overload the system. Decrease the audio level input to the transmitter or overload distortion sound may result.

Connecting the Audio Outputs

The 4W-1 KU QUAD receiver has one Unbalanced Audio Out (17) (adjustable Line level) SUM audio output and four Balanced

Mic Out (15) (fixed level) XLR jacks and each output works independently per Receiver. The Audio   Out is controlled by• (Up) or…, (Down) Buttons (7) for volume control and the receiver Sum Volume Meter (11) will indicate the level selected. For unbalanced output, plug an ¼” mono (Tip/ Sleeve) audio cable into the Unbalanced Audio Out (17) and plug the other end into your board or amplifier. When using the BT-1 KU instrument transmitter system, connect the Unbalanced Audio Out directly to your instrument amp or preamp. At maximum receiver volume setting, as indicated by the Sum Volume Level display, the system output is approximately +4dB higher than a direct cord-to-amp connection. Note that all receiver’s output will be mixed together as per the individual receivers’ volume settings as selected by the up/ down volume controls. If separate signals are required for each instrument then the Balanced Mic Out sockets must be used. However, they are not line-level or adjustable. The SUM out is best utilized for switching between separate transmitters during with only one audio signal at a time fed to the instrument amplifier. For balanced output, plug an audio cable with an XLR connector into each receiver and plug the other end into your mixing board or amplifier inputs accordingly.

Note: As when making any connection, make sure the amplifier or mixing board volume is at the minimum before plugging in the receiver to avoid possible sound system damage.

Your 4W-1 KU QUAD receiver is now operational and ready to use. Once you have completed the above steps, proceed to the following instructions for the HT-1 KU Handheld or BT-1 KU Instrument transmitter.

Note: Only one transmitter can be used with one receiver. It is not possible to use two transmitters on the same frequency and mix the output of these transmitters into one wireless receiver.

However, as this is a four receiver unit, four transmitters on separate frequencies can be utilized, one with each receiver.

Buttons Function

The RF Power Level Switch (27) is used to select Hi/Low power transmission.

Each time the Set Button (26) is pressed, the LCD menu will cycle in the following order:

l’IR/rl /’IE/VU > /,,’OLU/’IE > GROUP > **CHRl’mEL > **/’IR/tl /’IE/VU (repeats)

The …_ (Up) or,.. (Down) Buttons (25) work in the set mode only. They can be used to change any Group/Channel as selected (if not using IR Sync from receiver). They can also be used to select the desired Input audio level VOL setting. Or they can be used to turn on the LCD display.

During manual programming, the selected function will flash for five seconds, or press the Set button to confirm the selection and the display will return to the main menu.

Setting up the Transmitter

The HT-1 KU requires two AA size batteries to operate. To install the batteries onto the battery compartment, unscrew the Battery Compartment Cover (22) by turning counterclockwise until loose and slide down the cover, exposing the Battery Compartment (35). Insert two fresh AA batteries (36) according to the correct polarity as indicated on the transmitter body. Screw the battery cover back onto the microphone, making sure it is securely tightened. Fresh alkaline batteries can provide up to 8-10 hours of operation, but in order to ensure optimal performance, it is recommended that the batteries be replaced after 6-8 hours of use or as indicated to be necessary by the flashing Battery “BATT” Meter Icon (33).

Powering the On/Off

To turn on the transmitter, slide the Power On/Off Switch (28) to the “0 N” position. The LCD backlight will light up, indicating the unit is now on. After ten seconds the backlight will automatically turn off to conserve battery Iife. The Group (30), Channel (31), Input Volume Level (32), and Battery (33) indicator icons stay on for normal ration.

As many of the LCD battery meter levels should stay lit as possible, as they indicate usable battery strength. As the batteries weaken, fewer of  the level indicators will stay lit until only one bar shows, which will then flash to warn that the batteries are now too low and should be replaced as soon as possible with fresh ones.

To battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the power on/off switch to the “OFF” position. The LCD will display “OFF,” no LCD or backlight is lit up and the unit will be off.

At Power Off the transmitter will store the last settings entered and re- display them at the next power-on where it can be reprogrammed to any new Group/Channel or Volume level at the first time of use or anytime later. The factory default setting for Volume -10dB is same for all transmitters. These settings are optimal for most applications.

Programming the HT-1KU to the Selected Channel

The transmitter can be programmed to the same frequency as selected for the receiver, either via automatic synchronization using the IR Sync function or manually on the transmitter itself. IR Sync Programming:

Use the wireless IR LED Receptor Sensor (34) to download pre-programmed channels from the receiver. Start programming by holding the IR Receptor SensorNVindow.

Insert two fresh AA according to the correct as indicated on the transmitter body. Close the battery cover, ensuring the cover is snapped shut. Fresh alkaline batteries can last provide up to 8-10 hours of operation, but in order to ensure optimum performance, it is recommended that the batteries be replaced after 6-8 hours of use or as indicated necessary by the flashing Battery Meter “BATT” Icon (33).

Connecting Input Audio Source

Use the Audio Input (37) 3.5mm locking mini-jack for connecting the audio input cord from lapel mic (LT), Headmic™(LT/HM), or instrument (GT), depending on which version transmitter is being used. Secure the connection to the cable by lining up the slot of the 3.5mm mini connector and turning the ring to securely lock in.

Powering the Transmitter On/Off

To turn on the transmitter, slide the Power Off/Mute/On Switch (38) to the “MUTE” (middle) position (transmitter on, audio muted). The LCD backlight will light up.
The unit is now on. After ten seconds the backlight will automatically turn off. The Group (30), Channel (31), Input Volume Level (32) and Battery Meter (33) remain on in normal operation. As many of the five LCD battery levels should stay lit as possible, indicating usable battery strength. As the batteries weaken, fewer of the level indicators stay lit until only one bar shows,  which will then flash to warn that the batteries are now too low and should be as soon as possible. To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off,  slide  the  Off/Mute/On switch to “MUTE” and then “OFF”. The LCD will display “OFF”, no LCD or backlight is lit

up and the unit will be off.
At Power Off the transmitter will store the last settings entered and re- display them at the next power-on where it can be reprogrammed to any new Group/Channel or Volume level at the first time of use or anytime later. The factory default setting for Volume 0dB is same for all transmitters. These settings are optimal for most applications.

The transmitter can be programmed to the same frequency as selected for the receiver, either via automatic synchronization using the IR Sync function or manually on the transmitter itself.

Note: If procedure is not done correctly during the three seconds of active data transfer, the rece i ver and the do not link and transmitter’s previous programmed channel
unchanged. The IR link is infrared light and thus works best when this data transfer is accomplished in a light-shielded or darker environment. It may not be successful in a brightly lit area . If the transfer fails, the procedure in a darker location or somehow shield the link from outside light to success-fully program the transmitter with the pre-programmed group and channel info from the receiver.

Manual Programming (GRP/CH and Volume):

The transmitter’s frequency is set using the Set Button (42) and then the _.. (Up) or…,. (Down) Buttons (41). During manual programming, the selected function will flash for five seconds, or press the Set button to confirm the selection and the display will return to the main menu. To start, press the Set button once. The backlight on the LCD (40) will light up and the Group (30) icon will flash. Use the Up/Down buttons to change the group. When a group selection is finished, press the Set button again for the channel selection. The Channel Icon (31) will now flash. Again, use the Up/Down buttons to change the channel as desired. When the group/channel selection is done, press the Set button again to enter volume level input setting and then press Up/Down button to change in steps from 00dB to  -30dB (for loudest input) or press the Set button a second time to exit to the main menu.

To change volume input level only, the Set button three times to select the volume input level setting. Use the Up/Down to change in four steps from 0dB to -30dB (-30dB for loudest input). The level is preset at -10dB for LT/HM and 0dB for GT. These are optimal for most applications.

For normal operation, the transmitter should have the same Group/Channel as displayed on the receiver. The default factory setting
