2 Safety notes
This device amplifies electric audio frequency signals to operate passive speakers. Use the
device only as described in this user manual. Any other use or use under other operating con‐
ditions is considered to be improper and may result in personal injury or property damage. No
liability will be assumed for damages resulting from improper use.
This device may be used only by persons with sufficient physical, sensorial, and intellectual
abilities and having corresponding knowledge and experience. Other persons may use this
device only if they are supervised or instructed by a person who is responsible for their safety.
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like) from
the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.

DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or fire. If in doubt, seek advice from a regis‐
tered electrician.

CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.
NOTICE!
Risk of fire
Do not cover the device nor any ventilation slots. Do not place the device near
any direct heat source. Keep the device away from naked flames.

NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and
strong vibrations.
NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.
Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

NOTICE!
Magnetic fields
The device generates strong magnetic fields that can interfere with the function
of poorly shielded devices. The strongest magnetic fields are directly above and
below the power amplifier. Therefore, never place sensitive devices such as pre-
amplifiers, radio transmission systems, or tape decks directly above or below the
power amplifier. When installing the power amplifier into a rack, you should place
it in the lowest position, and further equipment such as pre-amplifiers in the
highest position.

4 Installation and operation
Unpack and check carefully there is no transportation damage before using the unit. Keep the
equipment packaging. To fully protect the device against vibration, dust and moisture during
transportation or storage use the original packaging or your own packaging material suitable
for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.

1POWER
Mains switch to turn the device on/off.
2 LED indicators for channels CH-A … CH-D
These LEDs indicate the ready status of the device (Power), the input signal level (Signal / –20 / –15 / –10 / –5),
channel overdrive (Clip) and a fault condition (Fault).
3CH-A … CH-D
Controls for input gain of channels CH-A to CH-D.
The Power LED is permanently lit during operation. The Signal / –20 / –15 / –10 / –5
LEDs respond to the input signal. If one of these LEDs is lit without an input signal
being present, disconnect the loudspeakers from the power amplifier and turn the
input gain control knobs of channels CH-A to CH-D to their minimum levels. If the
LEDs are still permanently lit, the device must be checked by an authorized technical
service centre.

5OUTPUT CH-A … CH-D
Signal outputs, designed as lockable NL4 panel sockets for connecting speakers.
6, 9, 10, 11 INPUT CH-A … CH-D
Signal input channels, designed as XLR socket pairs (input/output) for looping the signals through to other devices.
7Stereo | Bridge selector switch
Switch for toggling between “Stereo” mode (all channels are operating independently of each other) and “Bridge”
mode (two channels are combined into a single one with double power output).
8Lift | Ground selector switch
The Ground/Lift switch allows you to interrupt the connection between the device’s protective earth terminal and
signal ground in order to prevent hum loops (Lift/unpressed state: disconnected; Ground/pressed state: protective
earth terminal and signal ground are electrically connected).
