2 Safety instructions

This device amplies 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 sucient 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.

Do not use the device if covers, protectors or optical components are missing or

damaged.

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 re. If in doubt, seek advice from a regis‐

tered electrician.

CAUTION!

Possible hearing damage

With loudspeakers or headphones connected, the device can produce volume

levels that may cause temporary or permanent hearing impairment.

Do not operate the device permanently at a high volume level. Decrease the

volume level immediately if you experience ringing in your ears or hearing

impairment.

NOTICE!

Risk of re

Do not block areas of ventilation. Do not install the device near any direct heat

source. Keep the device away from naked ames.

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 re.

NOTICE!

Magnetic elds

The device generates strong magnetic elds that can interfere with the function

of poorly shielded devices. The strongest magnetic elds are directly above and

below the power amplier. Therefore, never place sensitive devices such as pre-

ampliers, radio transmission systems, or tape decks directly above or below the

power amplier. When installing the power amplier into a rack, you should place

it in the lowest position, and further equipment such as pre-ampliers in the

highest position.

NOTICE!

Possible damage due to installation of a wrong fuse

The use of dierent types of fuses can cause serious damage to the unit. Fire

hazard!

Only fuses of the same type may be used.

4 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 product against vibration, dust and moisture during

transportation or storage use the original packaging or your own packaging material suitable

for transport or storage, respectively.

Create all connections while the device is o. Use the shortest possible high-quality cables for

all connections. Take care when running the cables to prevent tripping hazards.

DANGER!

Electric shock caused by high voltages at the power amplier output

The output voltages of modern high-performance ampliers may result in death

or serious injury.

Never touch the bare ends of loudspeaker cables when the amplier is on.

NOTICE!

Magnetic elds

The device generates strong magnetic elds that can interfere with the function

of poorly shielded devices. The strongest magnetic elds are directly above and

below the power amplier. Therefore, never place sensitive devices such as pre-

ampliers, radio transmission systems, or tape decks directly above or below the

power amplier. When installing the power amplier into a rack, you should place

it in the lowest position, and further equipment such as pre-ampliers in the

highest position.

Depending on the individual application, the amplier can be used in dierent operation

modes:

Stereo mode

The two amplier channels operate independently of one another, either

channel (A and B) is amplied and connected to loudspeakers, the volume can

be controlled separately for the two outputs.

Parallel mode

The two amplier channels receive the same input signal from channel A and

loudspeakers are connected to each amplier, the volume is controlled via the

control knob for channel A.

Bridged mode

The two amplier channels are internally connected in such a way that twice

the output power is available. Only the input signal from channel A is amplied

and loudspeakers are connected only to the correspondingly marked output.

The volume is controlled via the control knob for channel A.

Possible operation modes

Installation and starting up

power amplier

16

For each output of the amplier, the total impedance resulting from the loudspeakers con‐

nected to it must not be below the allowed minimal impedance of the amplier output. If you

connect more than one loudspeaker to an amplier output, please note the following:

n If the loudspeakers are connected in a series, the individual impedances will be added up.

n If the loudspeakers are connected in parallel, the reciprocal of the total impedance equals

the sum of the reciprocals of the individual impedances.

Example: If you have two loudspeakers with the same impedance, their impedance doubles if

they are connected in a series, their impedance halves if they are connected in parallel.

The device has been designed for rack mounting in a standard 19-inch rack; it occupies two
