3. The digital system unit VSS 18

The fully digital system unit VSS 18 with integrated 18“ subwoofer has been
consequently developed to portable requirements. With a powerful bass base and very
compact dimensions as well as the lightweight of 34 kg, the VSS 18 is also the core and
control center within the self-powered PA-systems SD 7, SD 8 and also in directional
radiating active bass arrays.
Inside work a digital 24 Bit signal processor and three 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 cross-over, subsonic filter,
parametric EQs, peak/RMS-limiter, phase (180°) and delays. It serves also for a flexible
signal routing of the loudspeaker outputs (e.g. for top units / monitors / subwoofer).
Factory presets and user presets can be choosen, loaded and adjusted through a
navigation pad with a clear controlling sheme.
The integrated 18“ subwoofer provides a low-frequent radiation starting from 40 Hz to
160 Hz. The special tunnel geometry enables a high sound pressure with extra low

power compression and a low flow noise. The digital controlling enables a directional
(cardioid) dispersion (depending on preset) with a front-to-back damping of more than
20 dB in a wide frequency range. The subwoofer can be used in bigger production
surroundings (e.g. big indoor events) and also smaller installations.

The high-quality scratch- and impact-resistant black polyurethane coating offers optimal
road suitability. As an option you can choose a detachable and lockable roller base or
protective cover for protection. An additional protection of the loudspeaker offers the
comb-grid with acoustic foam and the special impregnation of the loudspeaker

membrane against moisture impacts.

In level control mode you define the pre-settings (dependence) of the single potentiometers
(volume controls) in relation to the output level of the different channels (Bass / Out A / Out B).
Consequently you have three possibilities:

1. All volume controls are independently adjustable from each other. (independent)

2. The volume control for Out A depends on system volume control (master), Out A is

adjustable from -∞ to +6 dB; the adjustment of Out B is independent. (A relative, B indep.)

3. The volume controls for Out A and Out B are depending on the system volume control

(master), they are adjustable from -∞ to +6 dB. (relative)

4. The volume control for Out A is pre-set by 0 dB and depends on system volume control
(master), but it is not adjustable. The volume control for Out B depends on system volume

control (master), it is adjustable from -∞ to +6 dB. (rel., lock A @ 0dB)

5. The volume control for Out A and Out B is pre-set by 0 dB and depends on system volume

control (master), but they are not adjustable. (rel., lock A+B @ 0dB)

Reset Preset
Are you sure?

Here you can reset the preset to the programmed initial state, that means you re-activate the
factory-made user preset on this memory cell and delete your preset. If you want to change one
or more menu items in a user preset, choose this topic and overwrite it with a new value and
press the OK button. Hence the new value is saved in the preset without entering all set
parameters again.

12

9. Choose your factory preset - play!

In this part of the user manual you will find a structured digest about the procedure for the
necessary settings with the main menu and its functions. If you pay attention to that
a riskless use of the VSS 18 is ensured.

10. The most important menu functions

10.1 Powering up

Switch on the VSS 18 when all volume pots are are turned fully anti-clockwise / left stop
and all connected components are switched on and muted previously to avoid an
unwanted sound reproduction.
Because the VSS 18 can be in „lock-function“ for rental purposes that means the VSS 18
may not (depending on adjustment) react on changes on the control panel and this can
cause an immediate reproduction when switching it on. Therefore it is necessary to mute
all connected devices previously.
After switching on the VSS 18 all volume pots should be turned to 0 dB (center click) with
deactivated „lock-function“ to keep a defined signal level and an optimal controlling
(this adjustment is a recommendation)

Note! During power on for the very first time Preset 1 „SD 7 OMNI“ is loaded! More
information about the initial state you can find on page 3.

10.2 Choosing presets

To control the respective system optimally the valid preset has to be load. You must
select it and load your latest PA-setup as preset on the control panel of the VSS 18.
Follow the instructions (e.g. select SD 8)!

After power on the VSS 18 for the very first time the left graphic appears on the LCD display. You
have to press the marked arrow key of the navigation pad once to select preset 2 „SD8 OMNI“
and confirm with the OK-key. In this case this procedure has to be done once again on the
second VSS 18 of the SD8.

If you control your PA system with an analogue audio signal, you can start now!

13

10.3 Switching input of channel A between analog / digital / digital X

If you want to control your PA system with a digital signal you have to switch the input of
channel A to „digital“ resp. “digital X” (see page 9). In the programmed initial state all
inputs are switched to „analogue“.

Press the marked arrow keys of the navigation-pad one after another (like shown in the scheme),
to switch the input of channel A to „analogue“ / „digital“ resp. „digital X” (the selection can be
looked up from the LCD display from the respective direction of arrow). After the correct selection
of the input of channel A press the OK-button and leave the menu with the left arrow key.

10.4 The „Mute- function”

This function enables to mute the PA system with just one touch of a button.

Press for 1 second the marked arrow key of the navigation pad to mute the PA system.
A repeated pressing of this arrow key causes the deactivation of the mute-function (see display).

14

10.5 Entering password

You can lock the VSS 18 with or without a password. To lock the VSS 18 with a
password (max. 8 digits) you have to enter it first.

This password can be changed

every time.

Note! Keep in mind resp. note down the entered password because if you want to

„unlock“ your VSS 18 you have to enter the password again (see next page). Should you
have forgotten the password, you have no possibility to re-activate the VSS 18. Please
contact the K.M.E. support! Should the entered password had been cleared, e.g. after a
rental, you have to assume a manipulation. Follow now the instructions to activate the
menu point!

10.6 The „Lock-function“

To lock your VSS 18 (with or without password) please do the following instructions:
Set all required parameters (also the volume controls) and press, like shown in the
graphics, the OK button for 2 seconds and your system is locked (now your VSS 18 is
ready for a rental, for example). When switching it off and on again the “lock-function” is
re-activated. That means you can not change any settings (depending on settings before)
while the “lock-function” is activated. To deactivate the “lock-function” you have to press
the OK button again for 2 seconds and, if entered before, enter your password by using
the arrow keys and confirm with OK.

Attention! If you have changed the position of the volume controls during the VSS 18

was locked you will be informed on the LCD display. Now you have two possibilities to
unlock the VSS 18: after entering your password (if entered before) you can press the
OK button for two times and the VSS 18 is playing in the current adjustment of the
volume controls or you press the OK button only once and turn the volume control(s) to
the previous position(s).

14. PA systems active: Set-up, connection shemes & system versatility

14.1 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 comes 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 wide­range 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
