5. INSTALLATION
1. Inputs wiring
• INPUT1, INPUT2, INPUT3, and INPUT4 have a balanced XLR
connector, useful to connect both low impedance microphones (30-
600Ω), both condenser microphones with 24V phantom power supply,
both line level audio sources (i.e. AM/FM tuner, cassette deck, CD
player, etc.). To choose the source to be connected, please use
the following selectors position (fig. 2 ref. 17): LINE position for
AM/FM tuner, CD player, Cassette deck etc., MIC position for low-
impedance dynamic microphones and PHANTOM position for
condenser microphones. INPUT1 is provided of VOX feature, when
a signal is detected, this input signal has priority over all the other
inputs, excluding all the other input signals. In this way only INPUT1
audio signal is amplified.
Attention
-Never connect a dynamic microphone when PHANTOM power is turned on, the
dynamic microphone could be damaged.
-Turn off PHANTOM power before connecting/disconnecting microphones connectors.
-Be sure that PHANTOM power is not turned on when you use microphones not
requiring external power. The phantom power, applied at pin 2 and pin 3, could
damage these microphones.
• AUX INPUT (INPUT 5).
L e R RCA input connectors allow the input of a stereo signal by left
(L) and right (R) inputs. This stereo input is useful to connect a
stereo external audio source.
• MAIN IN input and PRE OUT output.
MAIN IN input is connected to PRE OUT output by a jumper. It’s
possible to improve the overall sound quality inserting an external
unit (i.e. equalizer, compressor etc.). For connection wiring please
refer to the following picture.
• 24V DC input terminals
These two terminals allow the unit to be DC powered by an external
power source (i.e. 24V generator or battery). In case of AC power
fault or black out, the unit will be powered by 24 V DC, with automatic
and silent switchover to backup power.
• AC power IEC socket.
This IEC socket is intended to connect AC linecord to the AC outlet
(fig. 2 ref. 6).
Attention
Before connecting the AC linecord to the unit, please control that AC
power selector (fig. 2 ref. 1) matches the outlet AC power.
2. Output connections
Attention
To prevent the risk of electric shock, never touch amplifier outputs
when the amplifier is turned on.
• Speakers connection.
To access to the speaker connection terminals (fig. 2 ref. 8) remove
the protection cover unscrewing the screws.
This unit can be used both with constant impedance speakers (4Ω)
and with constant voltage speakers (25V, 70V, and 100V). Make
connections applying following instructions.
