yellow LED may light up occasionally. If the red CLIP LED lights up, this indicates that the signal is

To avoid damage to the equipment and to prevent the protection systems from being activated and

to ensure that the signal is reproduced correctly, check the output volume of the inputs assigned
to this output zone and the input gain of these inputs until the signal remains in the green zone.

1.- AC SELECT: power supply voltage selection.
2.- Speaker output terminals, screw connectors:
a.- LINE OUT BAL. UNBAL: line output of each zone (ZONE 1 to ZONE 4). Balanced line output
terminal for connecting the zone output signal to another power amplifier for amplification.
b.- POWER AMP. OUTPUT: speaker output for each zone (ZONE 1 to ZONE 4). Low impedance
output terminals 4-8 Ω and high impedance lines 100, 70 and 25 V. COM terminal is common for
low and high impedance.
3.- MONITOR - LINE OUT: line level output of the MONITOR signal, screw terminals.
4.- MONITOR - 1 W, 8 Ω: output for connection of a low impedance 8 Ω loudspeaker of the MONITOR signal,
screw terminals.
5.- PRIORITY: contact closure to enable the priority feature.
6.- INPUTS - TEL. PAGING: priority tel. switchboard input, assignable to output zones independently.
- T, R, G: tel. switchboard signal input, screw connectors.
7.- VOL: volume control of the TEL input PAGING.
8.- ZONE: selection microswitches to assign the TEL signal. PAGING to one or more output zones. To
send this signal to an output, set the switch to the ON position of the output zones or zones (Z1, Z2, Z3
and/or Z4) on which you want the input channel to be heard.
9.- INPUTS - CH 1-3: audio source inputs, combo connectors (XLR and 6.3 mm jack). Balanced and
unbalanced microphone signals and microphones requiring phantom power as well as balanced or
unbalanced line signals can be connected. The GAIN control allows you to adjust the input gain to
match the signal level to the amplifier. In addition, depending on the connected signal, you must adjust
the sensitivity using the input switch:
- LINE: line-level audio sources can be connected in this position. For example, a pre-amplified
desktop microphone.
