DESCRIPTION

ES 3323
is a mixer-amplifier with 4 mic-line inputs on removable connectors (the first input also has
an XLR socket), a CD/USB – MP3 player and tuner, an aux input for an additional external music
source.
The amplifier nominal power (320 W) is freely allocable to three 100 – 70 V separated outputs (3
system zones, for loudspeakers having 100 – 70 V transformers). A common direct output on 100
– 70 V constant voltage line and a low impedance (min. 4 Ω) 2 W output for a monitor loudspeaker
are available.
As (optional) system expansion, it is possible to link a second generic external amplifier (delivering
enough power for all loudspeakers, i.e. RCF UP 2321) to keep the background music in the zones
that are not paged.
When the external amplifier is foreseen, it is possible to send the music signal to either the ES 3323
internal amplifier or the external one.
The 3 PAGING buttons on the front panel can be used to select zones to be paged by either the
channel 1 or 4; a GENERAL call button is available as well. When connecting an additional external
amplifier and with no priority event in progress, the 3 PAGING buttons (if turned on) send the mix of
channels 1 ÷ 4 to the respective zones.
The 3 MUSIC buttons turn the music on (or send the mix of all inputs, when no priority event in
progress and ES 3323 is operating as a single stand-alone amplifier) in the respective zones.
The input1 has a signal detection circuit ('VOX') providing automatic priority operation.
All the inputs 1, 2, 3 and 4 can get the priority through an external command (connected to the
removable connector). The inputs 2 and 3 also have an RJ 45 socket for quick connection (through
CAT5 cable) of either a RCF BM 3001 or BM 3003 paging microphone or a line (daisy-chain) of BM
3003 (made of max. 12 microphones, by using an additional power supply unit).
A USB port (on the front panel) allows connection of a USB flash drive containing MP3 files.
Aux outputs are available to send the internal / external music source signals to additional amplifiers,
mixers, phone systems ('music on hold' function), etc. .
The 4 mic.-line inputs have a common 'presence' control and separate high-pass filters that are
useful to improve speech intelligibility.
Both the internal music source (CD/USB – MP3 player and tuner) and the AUX INPUT have separate
tone controls.
Front panel LEDs indicate the device state (ON, PROT), the priority activation (PRIOR) and the
signal level (SIG/PK).
