16 - COM 4Ω / 25V / 70V /100V
Speaker outputs terminals. 4 Ω terminal allows the use of standard speakers. Be careful, do not use loads
less than 4 Ω at risk of damaging the device.
The 25 V, 70 V or 100 V position requires speakers equipped with 25 V, 70 V or 100 V line transformers which
must be connected in parallel.
The sum of the powers of the speakers must not exceed the nominal
power of the amplifier
. For example, it will not be possible to use more than 24 x 10 W speakers.
17 - PREO OUT / AMP IN
Allows the connection to an external processing system (equalizer, etc.). Once the jumper removed, connect
the PRE OUT output to the input of the processing unit, then the output of the processing unit to the AMP IN
input. The jumper must stay in place if this feature is not used.
18 - LINE OUT
Signal output for external amplifier or recorder.
19 - AUX IN
Auxiliary input for CD or MP3 player.
20 - MIC/LINE inputs 1-2-3-4
XLR / ¼” Jack inputs. Input 1 is the priority input. When the presence of a signal is detected on input 1, inputs
2, 3, 4 and AUX are attenuated. The attenuation sensitivity is controlled by MUTE / SEN (22).
21 - Line / Phantom / Mic
3 positions selector for input signal type. Select “Line” for line level signals, “Mic” for dynamic microphone and
“Phantom” for electrets microphones. The Phantom power supply delivers 24 V.
22 - MUTE / SEN
Sensitivity control of priority for input 1 and TEL. (message player).
23 - Mains supply selector
Check the correct voltage before any connection to the mains supply.
24 - MON. LEVEL
Volume of the MONITOR output (25).
25 - 1W 8Ω / 600Ω
Outputs dedicated to monitor AUX input signal:
- terminals 1W 8Ω for a direct connection to a passive speaker, delivering 1 W into a 8 Ω load.
- terminals 600Ω for a connection to an active speaker or amplifier.
26 - TEL. INPUT
Terminals for a message player. Like input 1, this input has priority over inputs 2, 3, 4 and AUX.
MUTE / SEN (22) can be used for the attenuation sensitivity.
27 - TEL. LEVEL
Input level control of the TEL. INPUT (26).
