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.
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.
Intended use
Safety instructions
Proline 3000 9

DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a protective 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 registered 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.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for transport and installation.
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 trans‐
mission 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.

3 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.
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.

The unit has been designed for rack mounting in a standard 19-inch rack; it occupies three rack
units.

Power Amplier

Depending on the individual application, the amplier can be used in dierent operation
modes:
Stereo mode
Both power amp channels operate independently of each other, each input (A
and B) is amplied by one channel, speakers are connected to both channels,
the volume for both outputs can be controlled separately.
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
Both power amp channels are internally wired for providing double the output
power. Only the signal from input A is amplied, speakers are only connected to
the accordingly labelled output. The volume is controlled via the control knob
for channel A.
On each output of the amplier, the overall impedance resulting from the individual impe‐
dances of the connected speakers must not fall below the minimum allowable impedance of
the amp's output. If you want to connect multiple speakers to one amplier output, note the
following:

Installation and starting up

Power Amplier

nwhen connecting speakers in series, the impedances add up.
nwhen connecting speakers in parallel, the reciprocal value of the total impedance is equal
to the sum of the reciprocal values of the individual impedances.
This means, for example with two speakers with the same impedance: In series connection,
impedance is doubled. In parallel connection, it's halved.
Detailed information on this topic can be found in our online guide ‘Speakers’
(www.thomann.de).
