EXT AMP INPUT for a 100 – 70 V constant voltage line coming from the additional external
amplifier output.
Separate 100 – 70 V constant voltage ZONE OUTPUTS (one per zone) to connect loudspeakers.
See the section 'Loudspeaker connection'.
DIRECT OUTPUTS (not affected by zone selection, max. 320 W) to loudspeakers (100 / 70 V
constant voltage line).
The low impedance output (min. 4 Ω) allows to connect a monitor loudspeaker (max. power: 2 W).
Mains connector with fuse
Before connecting the power 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 MODES

ES 3323 CAN OPERATE IN 3 DIFFERENT MODES:
1. SINGLE:
as stand-alone amplifier for both paging and music.
The music is not held in zones not paged during a priority event in progress.
2. DUAL AMPLIFICATION 'A':
for paging only (while the internal one amplifies the music only).
3. DUAL AMPLIFICATION 'B':
for music only (while the internal one is for paging only).
i
'VOX' is an internal circuit that automatically activates the channel 1 priority when a signal is
detected on the audio INPUT 1.

SINGLE MODE OPERATION

OPERATION WITH NO PRIORITY EVENT IN PROGRESS

(after turning the amplifier on or when a priority command ends).
If no priority command is present (including VOX and SEQUENTIAL COMMAND
1, 2, 3, 4 and the music source are mixed together.
The music source can be:
•
The internal CD/USB – MP3 player and tuner.
•
The AUX INPUT signal.
•
Disabled.
The mixed signal is only sent to zones selected through the 3 MUSIC [11] buttons on the front
panel.
The master volume is adjusted by the MASTER
The volume of each input 1 ÷ 4 is adjusted separately by the controls 1, 2, 3, 4
The music volume depends on either the control of the CD/USB – MP3 player and tuner (if selected)
or the AUX IN volume control
o
The AUX INPUT volume also depends on the rear panel GAIN
