Safety instructions

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.

CAUTION!
Risk of injury due to heavy weight

Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.

NOTICE!
Risk of fire

Do not block areas of ventilation. Do not install 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.

Safety instructions

10

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 pre­amplifiers, 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.

Installation and starting up

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 high­quality cables for all connections.

Pin assignment

You can use XLR and 1/4" plugs with balanced or unbalanced wiring. In the following, we will
give you an overview of the various options

Main switch to turn the device on or off.

2 CH-A/B

Input gain control for the channels CH-A and CH-B.

3 LED indicators for channels CH-A/B

These LEDs indicate operational readiness of the unit (Power), the input signal level (Signal), overloading (Clip) and
fault condition (Fault) an.

During operation, the Power LED lights up constantly. The Signal LEDs respond to
the input signal. If one of these LEDs lights up without an input signal is present, dis‐
connect the speakers from the amp and turn the input gain control of both channels
down to minimum. If the LEDs continue to light up, the device must be inspected by
an authorized service centre.

10 Lift | Ground switch

Use the Ground / Lift switch to separate the connection between the earth pin of the device and the signal ground in
the unit. This prevents ground loops (position ‘Lift’ [switch is not pressed]: no connection. Position ‘Ground’ [switch is
pressed]: earth pin and signal ground are electrically connected).
