General Notes on Safety for Loudspeaker Systems

• Mounting systems may only be used for those loudspeaker systems authorized by the manufacturer and only with the mounting accessories specified by the manufacturer in the installation instructions. Read and heed the manufacturer’s installation instructions. The indicated load-bearing capacity cannot be guaranteed and the manufacturer will not be liable for damages in the event of improper installation or the use of unauthorized mounting accessories.

• The system’s load-bearing capacity cannot be guaranteed and the manufacturer will not be liable for damages in the event that loudspeakers, mounting accessories, and connecting and attaching components are modified in any way.
  Components affecting safety may only be repaired by the manufacturer or authorized agents, otherwise, the operating permit will be voided.

• Installation may be performed by qualified personnel only, and then only at pick-points with sufficient load-carrying capacity and in compliance with local building regulations. Use only the mounting hardware specified by the manufacturer in the installation instructions (screws, anchors, etc.). Take all the precautions necessary to ensure bolted connections and other threaded locking devices will not loosen.

• Fixed and portable installations (in this case, speakers and mounting accessories) must be secured by two independent safeties to prevent them from falling. Safeties must be able to catch accessories or parts that are loose or may become loose. Ensure compliance with the given national regulations when using connecting, attaching, and rigging devices. Factor potential dynamic forces (jerk) into the equation when determining the proper size and load-bearing capacity of safeties.

• Be sure to observe speaker stands’ maximum load-bearing capacity. Note that for reasons of design and construction, most speaker stands are approved to bear centric loads only; that is, the speakers’ mass has to be precisely centered and balanced. Ensure speaker stands are set up stably and securely. Take appropriate added measures to secure speaker stands, for example when:

  • the fl oor or ground surface does not provide a stable, secure base.
  • they are extended to heights that impede stability.
  • high wind pressure may be expected.
  • there is the risk that they may be knocked over by people.
    Special measures may become necessary as precautions against unsafe audience behavior. Do not set up speaker stands in evacuation routes and emergency exits. Ensure corridors are wide enough and put proper barriers and markings in place when setting speaker stands up in passageways. Mounting and dismounting are especially hazardous tasks. Use aids suitable for this purpose. Observe the given national regulations when doing so.

• Wear proper protection (in particular, a helmet, gloves, and safety shoes) and use only suitable means of ascent (ladders, scaffolds, etc.) during installation. Compliance with this requirement is the sole responsibility of the company performing the installation.

• WARNING! After installation, inspect the system comprised of the mounting fixtures and loudspeakers to ensure it is properly secured.

• The operator of loudspeaker systems (fixed or portable) must regularly inspect or task a third party to regularly inspect all system components in accordance with the given country’s regulations and have possible defects repaired immediately.

• We also strongly recommend maintaining a logbook or the like to document all inspections.

• Also be sure to provide sufficient safety margins for the rigging points used for fl own systems. Observe the given national regulations when doing so.

• Professional loudspeaker systems can produce harmful volume levels. Even prolonged exposure to seemingly harmless levels (starting at about 95 dBA SPL) can cause permanent hearing damage! Therefore we recommend that everyone who is exposed to high volume levels produced by loudspeaker systems wears professional hearing protection (earplugs or earmuffs).

General Inforation

Items delivered
When you first unpack your LINEAR 5 MK II speaker cabinet, please check that it comes complete with the Quick Start Guide, a PowerCon mains cable,instructions for safe commissioning and an RCS (Rain Cover Set).

Connections and controls

Input
XLR/jack combo socket, balanced input for analogue signals.

• The mid/high model has one input channel.
• The subwoofer has two separate inputs for the left and right signals. The two channels are equal and summed post-preamp, so you can use either one in mono mode.

Thru
Use this parallel, balanced XLR output to send the signal routed into the Input through to other components. This output remains active even when the electronic components are deactivated. The subwoofer has two of these ports.

Gain
Use this knob to adjust the input gain for the incoming signal.

• For the mid/high model –∞ (Mute) to +6 dB
• This knob adjusts the gain for both of the subwoofer’s stereo preamp channels in a range of -6 to +6 dB.
The centre-notched 12 o’clock position is 0 dB in both cases.
Note: The Gain setting does not affect the signal sent to the DSP Out.

Input/Limiter LED
This LED lights up green to indicate incoming signals. When it is red, either the limiter is active or the input is clipping. The LED briefly flashes red to tell you the Limiter is responding to signal peaks. If it stays red, turn down the Gain knob.

DSP Out
Balanced XLR socket, used to output the analogue input signal (coming from the Input socket). The signal can be processed with the internal DSP using the DSP CONTROL software. This means the DSP Out can serve as a network interface that lets you integrate an added powered speaker that is not originally network- compatible. In the factory default configuration, the unprocessed input signal goes straight to DSP Out, regardless of the selected preset and the Gain knob setting.

Ethernet In /Thru
Use the two etherCON ports to integrate the speaker into a network. They accept RJ45 and etherCON (NE8 MX, NE8 MX6, NE8 MC) plugs. Use the Ethernet Thru port to forward the network signal. Always use S/STP or S/FTP cables to shield against electromagnetic interference. We recommend CAT6 cables. A separate manual explains the finer points of network integration and remote control functions. You will find it on the LINEAR 5 MK II download page at www.hkaudio.com. For a brief description of the DSP functions, see section 8 Preset.

Data
This LED lights up orange when data is being transferred via the network socket.

Preset
Use the Preset selection button to call up factory presets or a user preset you can configure via the remote DSP CONTROL software. Tap the select button once to scroll through Presets 1 to 4. A separate manual explains how to program the four remote user presets. You will find it on the DSP CONTROL software download page at www.hkaudio.com.

Preset Overview

Factory presets: LINEAR 5 MK II 308 LTA

headstack cluster setup

Factory presets: LINEAR 5MK II 118 Sub HPA

118 HPA
Cardioid 2:1| For cardioid operation with two front-firing

LINEAR 5 MK II Sub 118 HPA

Factory presets 1 to 3 address the speaker only and not the DSP Out. Note: If you are operating the speaker in a network connected to the remote DSP CONTROL software, you can configure the DSP Out independently even when using factory presets 1 to 3. To learn more about this, consult the separate DSP CONTROL manual. You will find it on the DSP CONTROL software download page at www.hkaudio.com.

The Remote Preset

Remote
This lets you call up a user preset that you previously stored in the speaker via DSP CONTROL for the speaker as well as for the DSP Out. The speaker does not need to be connected to the remote software to do this.

The remote preset’s default setup is identical to factory preset 1 (Stand Alone and Front).
You can access the following DSP functions via the remote DSP CONTROL software and save your settings in user presets:
Fully parametric 10-band EQ with variable filter characteristics for each frequency band, high-pass and low-pass filters with variable filter characteristics, Limiter, Delay, Polarity, Level, and Mute.
You can configure these parameters separately and independently for the speaker and its DSP Out.

Power
This rocker switch turns the power on and off. Set it to Power to turn the electronic components on and to Off to disconnect them from the mains power supply. The mains switch has no influence on the PowerCon Link socket (see also 12 )

Power LED
As soon as the electronic components are supplied with voltage, this LED lights up green.

Mains Input
The mains connection is designed as a PowerCon socket. A corresponding mains cable is supplied. Make sure the PowerCon cable clicks into place and locks by pressing and turning it clockwise. To unlock, pull the locking device of the PowerCon connector towards the cable and turn it anticlockwise.

Link
This output can be used to supply power to up to three additional LINEAR
speaker cabinets with a PowerCon connection. This socket is permanently connected to the mains input and is not affected by the power switch. It carries voltage as soon as the mains input is connected to a live cable. It is therefore important that devices to be connected are switched off before they are connected to this output!

Auto Sleep
Use this recessed button to switch to energy-saving Auto Sleep mode on and off. Your speaker leaves the factory with the Auto Sleep button pressed to enable this mode. This function puts the electronic components into Auto Sleep when four and a half hours pass without the speaker registering an audio signal, data sent to the network ports, or operation of a button or knob on the electronics. The only way to wake it up is by switching the Power button off and on again or patching an analogue audio signal into the Input.
Heads Up: You cannot wake up the speaker via the network ports.
The only way to disable the Auto Sleep function is to press the recessed switch (not pressed).

Alignment

Single
The dispersion angle of the LINEAR 5 MK II 308 LTA is +5°/-25° vertically (fi g.1) and 60° horizontally (fi g. 2). Reflections from walls can be minimised by aligning the speakers horizontally. By turning the speaker, the sound can be focused on the listening area.

When using the LINEAR 5 MK II 308 LTA on speaker stands or mounting poles, it is not necessary to angle the speaker on the vertical axis. The MCT horn gives a vertical dispersion pattern similar to the curving of a properly set up component array. The sound energy is thus concentrated directly on the area to be covered.
If the speaker cabinet is arranged vertically (baffl e 90° to the installation surface):

• Although the speaker flange is designed for 0°, the vertical dispersion angle is +5°/-25°.

• The vertical acoustic centre axis is about -3°.

• Ceiling reflections are massively reduced due to this asymmetrical dispersion.

• The height of the speaker cabinet therefore defines the range. As a guideline: If the centre of the speaker cabinet is at a height between 2.50 m
  (Fig. 3) and 2.80 m (Fig. 4), the central axis hits the ears of the listeners after 15.50 m – 21 m for a person measuring 1.70 m tall.

• In rigging operations, horizontal and vertical alignment should preferably be achieved using the optionally available tilt bracket. Rigging the speaker cabinet allows for greater range and sound distribution over a larger area.

Headstack
Due to the asymmetrical dispersion of the MCT horn, the LINEAR 5 MK II 308 LTA makes it possible to operate two speakers acoustically correctly as a “vertical headstack”. In this scenario, the two speakers are coupled and the sound energy is bundled. This results in a vertical dispersion of +10°/-10° and a signifi cant increase in the sound coverage depth. If a greater sound coverage depth is required, the headstack version is recommended. To do this, the second speaker is rotated by 180° with its top plate placed on the top plate of the fi rst speaker (the upper speaker is then “upside down” and the front grilles of both speakers are facing forward) (Fig. 5)

Due to the asymmetrical arrangement of three feet and corresponding milled grooves in the speaker top plates, the two speakers stand on top of each other in a way that prevents them from twisting and shifting. The cabinets are then secured against being pulled apart vertically by using the two sliding plates on the left and right sides of the speaker.

We recommend the following system setup in stacking applications:

• With three LINEAR 5 MK II 118 Sub HPA subwoofers placed one above the other, the headstack consisting of two LINEAR 5 MK II 308 LTAs is placed centrally on the top subwoofer (Fig. 6).
• Heads up! Ensure additional tilt protection of the headstack, e.g. by using an M20 threaded bolt (diameter 35 mm) with a minimum length of 50 mm. Screw this onto the M20 thread of the subwoofer and place the speaker fl ange of the lower LINEAR 5 MK II 308 LTA onto it.
• There is also the industry-standard option of securing the headstack using lashing straps.

Cluster
Placing two LINEAR 5 MK II 308 LTAs next to each other to form a cluster extends the horizontal dispersion angle to approximately 140°. This requires a cluster opening angle of 30° (approximately 24 cm, see Fig. 7). This is important to minimise phase cancellation or elevations in the frequency response (phasing effects) (Fig. 8). The use of a cluster is recommended when a wide horizontal dispersion is required. The built-in MCT enables acoustically correct clustering.

To implement this application in rigging operations, a set consisting of a Pick Point and Cluster Plate is optionally available. This offers three attachment points for fastening slings and securing devices (e.g. steel ropes or round slings). At the same time, it protects against unintentional horizontal slippage of the speakers and offers the advantage of a rigid connection between the two cabinets. We recommend the following system setup in stacking applications: If three LINEAR 5 MK II 118 Sub HPAs are placed one above the other, the cluster is placed centrally on the top subwoofer using the DFP double flange plate or the PP-CP Pick-Point Cluster-Plate (Fig. 8). The Cluster Plate must also be secured to the M20 fl ange of the subwoofer with an M20 screw or the “HK Audio Tilt Unit”, for example. The same applies when using the “headstack cluster”.

For additional security, there is also the industry-standard option of securing the cluster using lashing straps.

Headstack Cluster
A headstack cluster is the largest expansion stage of the LINEAR 5 MK II 308 LTA. The combination of headstack and cluster is recommended when a large sound coverage depth with simultaneous wide horizontal dispersion is required. This results in a horizontal dispersion of 140° and a vertical dispersion of +10°/-10° (Fig. 9). Using the PP-CP ensures that the correct cluster angle for an acoustically correct cluster ring is fi xed. At the same time, the PP-CP provides the rigging points to rig the cluster of 4 using a steel cable or chain.

Setting Up Speakers

Setup on stands and mounting poles

General Information about Setting Up with Speaker Stands
Note! Always make sure the speaker stand is on solid footing and be sure to observe the manufacturer’s instructions as to its maximum load-bearing capacity.

Take care!

• Use only speaker stands that are stable enough to prevent accidental tipping. Ensure the speaker stand is designed to handle the cabinet’s weight. The highest setting on adjustable stands must be limited to prevent the combination of speaker stand and speaker from tipping. This applies when setting up the stand on a flat, horizontal surface.
• When setting up on an uneven or sloping surface, make sure the speaker stand’s base is secured to prevent accidental tipping, either by attaching suitable weights to the base or taking other measures to secure the stand.
• The use of any other fixtures or fittings can result in instability that may cause injury.

Setup with the Tilt-Unit

To ensure a safe setup directly on the subwoofers in a stacked configuration, HK Audio offers the Tilt-Unit as an accessory that can be screwed into the M20 mount of the LINEAR 5 MK II 118 Sub HPA just like a mounting pole. It secures the mid/high units from slipping. Heads up! In a stacked setup without the tilt units, the mid/high models must be secured against slipping, e.g. with a lashing strap.

4.1 LINEAR 5 MK II 118 Sub HPA
Deploy the LINEAR 5 MK II 118 Sub HPA as you would any other direct radiating subwoofer. However, when using in Cardioid mode, make sure that the basses are not set up next to each other but on top of each other and that there is at least 1 metre distance from walls. You have two cardioid setups to choose from: Cardioid 1:1 and Cardioid 2:1 Select the proper presets for the given setup on the rear panel of the sub-woofer. See section 2, 8 Preset for more on this.

The Cardioid presets attenuate the rearward sound pressure level by up to 34 dB, and boost the forward SPL by around 2 dB.

When does a Cardioid setup make sense?
While medium and high frequencies can be radiated in directional patterns, low frequencies are spherical. This often leads to an unpleasant excess of low bass on and behind the stage. Organisers are also increasingly setting precise demands for sound distribution, for example in marquees in city centres. The most effective way to achieve this in the bass range is with Cardioid technology (cancelling out the frequencies radiated to the rear). The 118 Sub HPA therefore meets all the requirements for quickly and easily implementing effective cardioid setups, both mechanically and with the available filter sets.

Example systems

For to ensure the most balanced image possible, centre the subwoofer between the two mid/high units.

Setting up Speakers on Poles

If you wish to place mid/high units on speaker poles rather than stands, simply screw a pole with an M20 thread into the M20 pole mount on the LINEAR 5 MK II 118 Sub HPA.

Presets:

Configuring a 1:1 Cardioid Setup
Cardioid system with a speaker pole. The bottom subwoofers are directed to the rear.

Presets:

Combination with LINEAR Series speakers (e.g. LINEAR 5 LTS A, LINEAR Sub 4000 A, etc.)
To combine existing LINEAR 5 LTS A mid/high units or other LINEAR speakers with LINEAR 5 MK II 308 LTA or LINEAR 5 MK II 118 Sub HPA, the use of the DSP CONTROL software is required. This allows either the speaker itself to be edited via the Remote Preset or the DSP Out to suit the application combination. A selection of possible combinations with described settings and matching presets can be found at www.hkaudio.com and the corre-sponding product page.

Optional HK Audio Accessories
