Dear Customer!
The power output stages of the product line ITEC MULTIPOWER are well-known for their robust-
ness and
reliability. They are designed for continuous operation as part of professional installations. Dy-
namic limiters ensure an effective overload protection, preventing distortion and damage to the
speaker systems. A
temperature-controlled fan guarantees optimal operating temperature in the case at any time while
keeping noise levels low. A series of protective features provides operation at highest-possible
security levels.
We assure you to have taken the right decision in purchasing an ITEC MULTIPOWER power out-
put stage. State-of-the-art technology is paired with best usability, functionality-focussed design,
small form factor
and various valuable details.
Please read this manual carefully and follow the instructions given. You will enjoy many years of
hassle-free operation in doing so. In case of any questions regarding sound engineering, presen-
tation setup, media
remote control and training room equipment, we will be very happy to help.

FRONT PANEL
1. POWER SWITCH
Used to turn the power output stage on or off (additionally, all auxiliary devices connected via the
AC-OUT socket are also switched on or off).
2. POWER LED
If lit in green, power is available, power switch or remote power-up is activated, fuse is ok.
3. LEVEL CONTROL for CHANNELA and B
4. STATUS LEDs
- GREEN: Signal – an audio signal is being processed (level control is open)
- YELLOW: High input levels, limiter is active to prevent distortion
- RED: Protective switch activated (short circuit, overheated, etc.)
REMARK:
Every ITEC MULTIPOWER power output stage ships with a transparent shield made from plexiglas
and two screws. This shield can be used to prevent unauthorized access to the level controls.

3. POWER SUPPLYAC-OUT
You can supply power to auxiliary devices like pre-amplifiers, wireless transmitters and playback
devices via this socket. These devices will also be powered on/off together with the MULTIPOWER
power output stage.
CAUTION: Do not connect other power output stages via this socket. The fuse is not designed for

Jack: Tip……Signal +
Ring….Signal –
5. SIGNAL INPUT TERMINALS
Alternative input to XLR / jack socket.
6. REMOTE MUTE INPUT
Remote control input for muting inputs - electrically isolated. For wiring see connectivity layout.
7. GROUNDLIFT SWITCH
If you activate “groundlift”, the device is separated from ground.
8. BRIDGE SWITCH
Switch from 2-channel to bridge mode. Bridge mode mixes inputs A and B. Input signal levels can
be set by the level controls on the front panel. For output wiring, see connectivity layout.
9. OUTPUT TERMINALS 100V (only for 2x200T and 2x300T)
You can connect 100V speaker systems to these terminals (see connectivity layout).
10. LOW-RESISTANCE OUTPUT TERMINALS
You can connect low-resistance speaker systems to these terminals (see connectivity layout)
11. OPERATION MONITORING
Potential-free contacts to monitor operation. Circuit closed if MULTIPOWER is ready for operation.
For wiring see connectivity layout.
12. REMOTE POWER-ON (optional)
If your MULTIPOWER is equipped with this option, you can remote control it using a 12V line (see
connectivity layout). The power switch on the front panel has to be turned on to enable remote con-
trol.
