3. Digital System Unit VSS 28
The VSS 28 is a fully digital system unit including an integrated 2 x 8” hybrid subwoofer,
a 24 bit / 48 kHz audio DSP and three class D amplifiers (1 x 400 W subwoofer + 2 x 200
W tops). The VSS 28 is extremly compact and very light-weight (21.5 kg). The VSS 28 is
the heart and control centre for compact and freely configurable PA- and installation
systems. The integrated 8” neodymium speakers with a hybrid shell offer powerful and
precise bass sound reproduction starting at 45 Hz up to 160 Hz. The optimized tunnel
geometry allows a high sound pressure level at a low power compression and reduces
the air flow noise to a minimum. The high-quality scratch- and impact-resistant black
polyurethane coating offers optimal road suitability. An additional protection of the
loudspeaker offers the sound-permeable comb-grid with acoustic foam. Further, a special
impregnation protects the loudspeaker membrane against moisture impacts. A 24 bit
audio DSP and three powerful class D amplifiers which are powered by switch mode with
PFC (Power Factor Correction) work on the inside. For the first time the analogue input
signal is digitalized directly inside the input amplifier using an intelligent 24 bit AD
converter and remains digital until amplified in the class D amplifiers. Thanks to newest
digital technology the dynamic range of the audio signal increases in reducing conversion
losses to a minimum. The result is a sophisticated crystal-clear audio reproduction. The
digital input is based on an AES EBU & S PDIF signal with a sample rate of max. 192
kHz. The powerful audio DSP provides an optimal signal routing and controlling of all
adjustable parameters by using a PC software. There, the Gain, the digital Crossovers
with 12 dB 24 dB per octave, the subsonic Filter, the full parametrical EQ`s, the peak
RMS Limiter and the Delays can be adjusted. By using the three menu item buttons you
can adjust the system settings and load Factory or User Presets (also from SD Card).
Every Factory Preset already offers a wide range of solutions for diverse operating
options and user applications.

• 7.2 Volume And Limiter Control
If you would like to change the volume of your system you can
adjust it directly on the VSS 28 by using the System Volume Control
(Level Control). You also have the possibility to activate and use the
Limiter. The control has two different operating modes/
functions which can be adjusted under the Menu Item “Mode” (see
7.1). In the first four sound settings only the System Volume Control
can be used while in the following settings only the Limiter Control
can be used. In the Menu Item “Mode” the LED “Limit” indicates
whether the Limiter is enabled or disabled.
SYSTEM VOLUME CONTROL
Is the LED “Limit” not light up, the Volume Control is active. The input level of the
audio system can be adjusted from -∞ to +6 dB. If the adjusting slot is in the
vertical position the input level is adjusted to 0 dB.
LIMITER
If the LED “Limit” lights up, the Limiter Control is active. You can limit the level of the audio
system from -24 dB to 0 dB. Is the control adjusted to 0 dB the Limiter is disabled. In the
fully clockwise position the control is adjusted to 0 dB. In the User Presets the Limiter
Control is not available.
Note: You can not turn the control by using your hands as the control is recessed in the chassis.
The control can only be adjusted by using a slotted screwdriver or another suitable tool.
• 7.3 User Presets
You have the possibility to create four different User Presets or to change them for your
own purposes. All sound settings, changes of parameters and system adjustments are
editable with the K.M.E. preset editor software (for PC only). It offers a wide range of
recources to design the sound of your audio system. For more details about indicators
and choosing a preset, see 7.1.
Note: The Menu Item “Mode” is not available in a User
Preset.
SOFTWARE AND FILE FORMAT
The preset editor software saves the finished preset as a KPX file. These User Preset files
are named “VSS28UP1.kpx”, “VSS28UP2.kpx”, “VSS28UP3.kpx” or ”VSS28UP4.kpx” and
are NOT to be renamed.
Please save the files on an SD Card (FAT32) and insert it into the VSS 28. Now, the User
Presets can be loaded and used.
Note: The system unit reads the SD Card and recognizes a maximum of 4 User Presets
(as mentioned above) which you can choose. However, only the existing User Presets on
the SD Card are displayed! It is not possible to choose a User Preset in the Menu Item
“Preset” to save on the device if the VSS 28 finds none of the above file names on the SD
Card.
FIRMWARE UPDATE
If you want to update the firmware please read the enclosed User Manual for updates.

8. Quickstart
In this part of the Manual you will find an overview on how to do the first steps at the
startup and adjust the necessary settings and its functions. In complying with these
procedures, a safe use of the VSS 28 is guaranteed.
After setting up the PA system and connecting the cables (SD X or a alternative Versio
system; see 6.) and switching on the VSS 28 you should initially check the adjusted
parameters of the Menu Items and change them if necessary. To control the respective
system optimally, the correct preset has to be loaded. Therefore, you should choose and
load your current setup under the Menu Item “Preset”. Please follow the instructions of
7.1 for operating the system.
For a defined and optimum signal level the System Volume Control may to turned to 0 dB
(the adjusting slot is in the vertical position) by using a suitable tool (see 7.2). This
adjustment is a recommendation!
If you use an analogue input audio signal for your PA system you can start
immediately!
If you want to use a digital input signal for your audio system you have to switch the Input
of the VSS 28 to “Digital” (LED indicator: “left”, “right” and “digital”; see 7.1). In the
Delivery Status, the Inputs of the VSS 28 are switched to analogue.
Note! When you power up the VSS 28 for the first time the Preset 2 “VERSIO SD X” is
loaded! For more information on the Delivery Status see Page 3.
