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 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 floor 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 mounting fixtures and loudspeakers to ensure it is properly d.
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 flown systems. Observe the given national regulations when doing so.
Professional loudspeaker systems can produce harmful levels. Even prolonged exposure to seemingly harmless levels (ing at about 95 dBA SPL) can cause permanent hearing damage! More we recommend that everyone who is exposed to high volume produced by loudspeaker systems wears professional hearing vision (earplugs or earmuffs).

Input Thru Gain DSP OutL7 XA/FA models
text_image
Input L Thru Gain 0 dB 3 6 dB-6 dB DSP Out 4 1 2 3 4 R 1 2 5L7 118 Sub A
① Input
This XLR/1/4" (6.35 mm) combo jack provides a balanced input for analog signals.
• L7 XA/FA models have one input channel.
- The L7 118 Sub A subwoofer has two separate inputs for the left and right signals. The two channels are equal and merged post-preamp, so you can use either one in mono mode.
2 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.
3 Gain
Use this knob to adjust the input gain for the incoming signal.
- The control range for the XA/FA models sweeps from - (mute) to +6 dB.
- This knob adjusts the gain for both of the L7 118 Sub A's stereo preamp channels in a range of -6 to +6 dB.
The center-notched 12 o'clock position is 0 dB in both cases.
Heads up: The Gain setting does not affect the signal sent to the DSP Out.
4 Input/Limiter LED
This LED lights up green to indicate incoming signals and red to indicate signal peaks. The LED briefly flashes red to tell you the Limiter is responding to signal peaks. If it stays red, turn down the Gain knob.
5 DSP Out
Use this XLR port to forward the signal routed into the Input jack or to forward a digital audio signal streamed* in via Milan™, an AVB-based digital audio network protocol. The onboard DSP can process both types of signals. This means the DSP Out can serve as a network interface that lets you integrate an added powered speaker that is not equipped with Ethernet ports. You can even use it as an audio interface to send audio signals streamed* in to the LINEAR 7 speaker on to other speakers, for example, to powered LINEAR SUB series subwoofers.
In the factory default configuration, the unprocessed input signal goes straight to DSP Out it, regardless of the selected preset and the Gain knob setting.

This socket can power up to three additional LINEAR 7 speaker cabinets. Hardwired to the Mains Input, it is not affected by the Power switch setting. The Link circuit goes live the moment you connect the Mains Input to a power source. This is why you must make sure all downstream devices are switched off before you connect them to the Link port.
13 Auto Sleep
Use this recessed button to switch 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 to sleep when four and a half hours pass without the speaker registering an audio signal, data sent to the Ethercon ports, or an adjustment of a button or knob. The only way to wake it up is by switching the Power button off and on again or patching an analog audio signal into the Input.
Heads up: You cannot wake up the speaker via the Ethercon ports. There is but one way to deactivate the Auto Sleep function – by 'unpressing' the button to set it to the up position.
3 An Overview of the Various LINEAR 7 Models
natural_image
Five line drawings of speaker speakers arranged in a row, showing different speaker positions (no text or symbols present)L7 110 XA L7 112 FA L7 112 XA L7 115 FA L7 118 Sub A
The LINEAR 7 series consists of four mid/high units and a subwoofer, the L7 110 XA, L7 112 XA, L7 112 FA, L7 115 FA and the L7 118 Sub A. The housings of the multifunctional L7 110 XA and L7 112 XA models are angled 30^ so you can also set them sideways for use monitors. The larger housings of the L7 112 FA and L7 115 FA fullrange models deliver more low-frequency sound pressure.
text_image
30°L7 110 XA / L7 112 XA
All XA and FA models are loaded with rotatable horns. The directivity of each cabinet's horn is optimized for its primary purpose – that is, the most frequently used application. The L7 110 XA cab sports a 10" woofer and a horn with a wide 80°x60° throw pattern to provide uniform near-fi eld coverage. L7 112 XA/FA cabs feature a 12" woofer and a horn with a medium 70°x50° throw pattern. The L7 115 FA cab comes with 15" woofer and a horn with a narrow 60°x40° long-throw pattern.
You need tools to rotate the horns, so they are not conducive to frequent adjustment. The idea is to optimize the throw pattern for the cabinet's primary application.
Tip: You do not have to rotate the horn when setting the cab on its side for use as a stage monitor. In fact, the upright speaker's narrower vertical throw pattern works great in the horizontal position. Its tightly focused directivity minimizes overlap with adjacent monitors and reduces the risk of feedback risk because you can aim the speaker more accurately.
4 Setting Up Speakers
4.1 The XA/FA Models
LINEAR 7 mid/high units may be stacked on subwoofers, mounted on speaker stands or poles, installed with wall brackets, or fl own with the proper rigging hardware.
Setting Up with the DuoTilt 3/7
text_image
-3° -7°All mid/high units feature the HK Audio DuoTilt 3/7, a special mount for 35 mm speaker stands and poles offering two angles, -3° and -7°, to provide better coverage. The DuoTilt 3/7 is sited closer to the baffling to maintain the optimum center of gravity when the speaker is on a stand.
Setting Up with the Tilt Unit
text_image
-3° -7° Tilt-UnitHK Audio offers an optional Tilt Unit if you wish to tilt the mid/high units when they are stacked directly on subwoofers. It screws into the subwoofer's M20 mount just like a speaker pole. This lets you take advantage of the DuoTilt's -3° and -7° inclination angles in stacked setups with the Tilt Unit holding the mid/high units in place.
Caution! If you do not use the Tilt Unit to stack mid/high units, be sure to secure these cabinets in place, for example, with lashing straps.
General Info about Setting Up with Speaker Stands
Heads-up: 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.
Caution!
- Use only speaker stands that are stable enough to prevent accidental tipping. Ensure the speaker stand is designed to handle the cabinet's weight. Adjustable stands' highest setting must be limited to prevent the combination of speaker stand and speaker from tipping. This applies when setting 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 result in injury.
Rigging:
natural_image
Diagram showing a person emitting a beam of light from a target, with no text or symbols present.All XA and FA models can be flown by installing the AP-8 attachment and steel cables or chains to their rigging points, or by installing the proper truss brackets.
FA models provide heavy-duty 4x5 mm threaded inserts in the side-mounted shell grips serving to attach the HK Audio TB-45N or TB-45NQ (the Q stands for quick-release pins). XA models' wedge monitor-like angled panel does not accommodate a shell grip, so they come with reinforced 2x8 mm threaded mounting points that let you bolt on the HK Audio TB-28N truss bracket. Mounting instructions are enclosed with the truss brackets.

4.2 L7 118 Sub A
Deploy the L7 118 Sub A as you would any other direct radiating subwoofer. However, do not stack the bass bins when confi guring cardioid setups. Instead, place them side by side, maintaining a distance of at least one meter from walls. You have two cardioid setups to choose from - Cardioid 1:1 and Cardioid 2:1. The diagrams below show the front view from the audience's perspective.

text_image
Rear: -34 dB Front: +2 dBWhen is it a good idea to go with a cardioid setup?
While speakers are able to throw midrange and high frequencies in directional patterns, low frequencies tend to radiate in all directions. Excessive bass levels can often be a problem on and behind the stage. And promoters are increasingly making demands to limit sound systems' low-end reach, for example, in festival tents at urban venues. Such demands for limiting low-range frequencies' range are best met with cardioid setups. With its hardware appointments and filter sets, the L7 118 Sub A provides a fast, easy way to configure effective cardioid setups.
5 Example Systems
5.1 Setting Up a 2.1 Stereo System
With the benefit of the L7 118 Sub A's onboard stereo preamp, you can easily set up a 2.1 system routing both the left and right channels into the L7 118 Sub A and then forwarding their signals to the mid/high units via its two Thru ports. The L7 110 XA's wide throw patterns are perfect for this application.
