3. The completely digital audio system VL 750 / VL 760
The completely digital audio system VL 750 / VL 760 offers excellent sound performance
with an extremely high output power, compact dimensions, low-weight as well as an
absolutely versatility as top unit, monitor, full-range or delay line and fill system. The
VL 750 / VL 760 is also ideal combinable with VERSIO subwoofers. It has been
consequently developed and optimized to portable and installation requirements.
The integrated 12“ resp. 15“ + 1“ neodymium drivers and the integrated innovative digital
technology reduce the weight. The bass reflex housing provides a low-frequent radiation
starting from 50 Hz. The special tunnel geometry enables a high sound pressure with
extra low power compression and a low flow noise.
Inside work a digital 24 Bit signal processor and two powerful class D amplifiers with an
unsophisticated, crystal-clear sound quality (without conversion losses due to full digital
preamping). The analogue input signal is digitalized directly inside the input amplifier
using an intelligent 24 Bit AD-converter and remains consequently digital to the class D
amplifiers` output. The audio-DSP enables an optimal processing and controlling of the
audio signal through adjustable parameters like gain, digital low-cut filter, subsonic filter,
(parametric) EQs, peak/RMS-limiter and delays.
With the simple controlling of the system menu with only one navigation pad, you can
select, load and programme factory presets resp. user presets. Due to the audio-DSP
extensive solutions are available for various using possibilities (see page 25). All factory
presets can be set as user presets.
The high-quality scratch- and impact-resistant black polyurethane coating offers optimal
road suitability. An additional protection of the loudspeaker offers the comb-grid with
acoustic foam and the special impregnation of the loudspeaker membrane against
moisture impacts. As an option you can choose a protective cover, wall mount, flying
frame, M8 eyebolts.

8. Operation
All these software parameters must be set directly on the hardware device. The sub
menu “User preset” where you can set parameters like gain, crossover frequency, limiter,
delays,…appears from preset no. 5 - 8.
The names of the menu points refer to the user navigation on the device.
Main Menu
• Pot Lock Mode [to be activated by using “lock function”, see page 13]
Pot locked [just lock volume pot]
Pot unlocked [just unlock volume pot]
In this menu item you can set a „lock - function“ for the volume pot of VL 750 / VL 760.
• Sig LED Threshold
Here you can set the threshold value where the LED starts to light green when the set value is
reached by the audio signal.
• User LED Threshold
Here you can set the threshold value where the LED starts to light blue when the set value is
reached by the audio signal. This function allows you to set an optical limit for the volume level
for your audience, e.g. -10 dB – you know your pre-set value is reached.
• Power Mode
Last State
Audio Trigger
Always On
In this menu item you can pre-set the operating status of the VL 750 / VL 760:
If you choose „Last State“- mode, the VL 750 / VL 760 will always start in the last state of
operating after power cycle the unit (after power cycle the unit is muted!).
To reduce the power consumption e.g. in installations you can choose „Audio Trigger“- mode.
In this mode you can set a threshold value and a time value where the system automatically
switched off when the threshold is not exceeded with an audio signal. After the pre-set time the
unit is switched off. If the pre-set threshold value is exceeded during the unit is still on, the time
value counts again - that means this function is a posttrigger-function. You can switch on the
unit again by pressing the OK-button or playing an audio signal which has a higher input level
as the pre-set threshold value.
If you choose „Always On“, the VL 750 / VL 760 is always on. That means after apply power
supply the unit is automatically on and ready to play (the “lock function” can be active!).
• Display Mode

• At first remove the top (u-bracket) of the flying frame and put it aside.
• Unscrew now the four screws of the flying frame. After this you have to fix the VL 750 / VL 760
within a vertical position of 0° into the lower part of the flying frame.
• Unscrew the three plastic-screws on top of the VL 750 / VL 760. After this you have to fix the
top part of the flying frame on the box with the three delivered screws.
• Now you have to screw on the top part onto the lower part of the flying frame with two screws
on the left and right side to fix the VL 750 / VL 760.
• At last step you have to mount the top (u-bracket) of the flying frame again to finish the
installation. If you have some additional accessories for flying the VL 750 / VL 760, you can
mount it now. Attention! Please mind that the user is responsible for safely flying the
equipment (according to BGV_C1).

11.2 Set-up PA systems
Note!
Please note specific and useful set-up of a first-class loudspeaker system. A universal
statement about the correct (standard)-adjustment and set-up of PA systems is
impossible, because each reinforcement is bound to a different place and has always
different features.
When using high stands or distance rods for top parts the user has to guarantee the
stability. Please use just certified mounting material when installing the systems to
guarantee the safety. Depending on the features of the area/room to be reinforced the top
unit(s) can also be swiveled a bit horizontally and tilted vertically to reduce reflections (on
walls + ceilings) and interferences and therefore achieving a better utilization of the sound
energy.
If covers are opened or sections of casing are removed, except where this can be done
manually, live parts can become exposed. If it is necessary to open the unit this must be
insulated from all power sources.
Please mind that it is not coming to a ground loop during cabling of the system. If it
comes to deep-frequent hum switch the Ground-Free to „Free“. Always use balanced
signal cables if possible. Do not mask or detach the conducter connection on the mains
plug! Danger!
High loudspeaker levels can cause permanent hearing damage. You should therefore
avoid the direct vicinity of loudspeakers operating at high levels. Wear hearing protection
if continuously exposed to high levels.
When should I choose a directional or omnidirectional dispersion in the low-frequency
range?
Each direct radiating subwoofer has a omnidirectional dispersion in the low-frequency range.
Depending on local conditions it can come to spatial interferences. The cardioid dispersion
pattern resulting from this approach avoids unwanted energy behind the system that greatly
reduces the reverberant field at low frequencies and provides the greatest accuracy of low
frequency reproduction.
The directional (cardioid) dispersion offers a lot of significant advantages in the all-day
reinforcement work. The highest sound energy will be radiated just in the front very
homogeneously, on the side the damping increases and achieves on the rear side a very wide-
range excellent damping quality at all frequency range of more than 20 dB. For the first time the
whole frequency band from bass to mid/high can be adjusted to the audiences’ area. Especially in
an acoustical different location like marquees, glas buildings, open airs with level restriction or in
halls with large reverberation time the cardioid technology is an advantage. Even at very high
volume levels develop considerably less wall- and ceiling-reflection. The complete bass
reproduction explicitly gains in pressure and precision.

SD 7 consists of: 2x VSS 18 + 2x VB 18 + 2x VL 750
1. Set-up PA: - place a VSS 18 to the left and right side in front of the audience
(on solid underground)
- place a VB 18 each on a VSS 18 or directly next to a VSS 18 (front in line)
- place the top units each on a distance rod on the VSS 18 or each on a high
stand (front in line)
2. Connection: - apply power supply connection always with the supplied PowerCon cable on
VSS 18 + VL 750 on one 16A fused electric circuit
- plug in the left + right audio signal (XLR cable) each on channel A on the
VSS 18, after this you have to link each audio signal with a XLR cable to the
top units (e.g. with a dual-cable from K.M.E., which includes the audio signal
and the power supply)
- connect the speaker output „Out A“ of VSS 18 each with a passive subwoofer
VB 18 with a Speakon cable (in this preset the speaker output „Out B“ is
configured for a passive top unit – crossover frequency 120 Hz)
- switch on the system components successively, Note! please turn down all
volume controls before switching on the system components to avoid an
undesirable sound reproduction, because the system components can start
in the “lock-function” (depending on adjustment), that means it may not react on
changes on the control panel
- after switching on the system components it is advisable to set the volume knobs
to „central click“ (=0dB) to have a defined volume level
- the volume controls for „Out A” and „Out B” are depending on the system volume
control (master), they are adjustable from -∞to +6 dB
