Operation Manual

ENGLISH

[ PAGING RELAY contacts (3 pin removable connector).

The internal relays switches when a priority command is present.

1. normally open

2. common

3. normally closed

Max. voltage on contacts: 24 V; max. current: 0.5 A

] Ampliﬁer output (AM 2160: max. 160 W; AM 2320: max. 320 W) to loudspeakers

(100 / 70 V constant voltage line – 4 Ω impedance).

Use 1 output only (read the section ‘Loudspeaker connection’).

A Mains connector with fuse

Before connecting the power supply cable, verify that the apparatus voltage (230 or 115 V ac)

corresponds to the available mains supply.

Note: the fuse type is marked on the rear panel (below the mains connector).

OPERATION

VOX’ is an internal circuit that automatically activates the channel 1 priority when a signal is

detected on the audio INPUT 1.

POWER ON (OR WHEN A PRIORITY COMMAND ENDS)

If no priority command is present (including VOX and CHIME SEQUENTIAL COMMAND), all the

channels 1, 2, 3, 4 and the selected AUX INPUT are mixed together.

The music volume (coming from a CD / MP3 player, a tuner, etc.) depends on the aux input

volume control on the front panel (see 2) and also the relevant GAIN control setting (see 15 and

17) on the rear panel.

The aux inputs can be activated / muted through the front panel buttons (see 3 and 4).

PRIORITY

If a priority command is present (or VOX), the selected AUX INPUT can be either included in the

mixed signal sent to the ampliﬁer or excluded, according to dip-switch no.1 setting (see 20: the 8

dip-switch group).

During a priority command (‘PRIOR’ LED turns on), only the audio signal of the channel with priority

(and an AUX INPUT, if turned on) is sent to the ampliﬁer (and the PRE OUT output).

The selected aux input is always excluded from the signal sent to the ampliﬁer when the

CHIME SEQUENTIAL COMMAND is activated.

The priority mode and the VOX function are set through the dip-switches no.2 and no.3 of the 8 dip-

switch group (see 20):
