MAINS CONNECTION
The power supply source transformer has been designed for 230 V AC.
BATTERY CONNECTION (24 V DC)
When using a 24 V DC battery as power supply, connect the amplifier to earth using the earth
terminal. The system is electrically more stable if the chassis is connected to earth.
NOTE:
The connection cable to the batteries must have a series rating fuse. The fuse must be
F30A quick cut off type. When connecting the battery, make sure to respect polarity.
SPEAKER CONNECTION
There are two speaker outputs that correspond to the
two speaker zones
.
The main
MUSIC/SPEECH
output offers output at all times, reproducing the signal present in
the amplifier input. It is the general output for 8
Ω
and 100 V high impedance line speakers.
The secondary SPEECH ONLY output only reproduces the input signal when the priority has
been activated using the circuit closure in the PRIORITY terminals. This function is useful when
you want a second speaker zone that only occasionally receives announcements. The PRIORITY
circuit can be closed by a microphone or a switch. In this case the SPEECH ONLY output can be
used as a second zone that is activated or deactivated by a switch.
