IMPORTANT NOTES
OPERATING PRECAUTIONS
Also check the suitability of the support surface to which the product is anchored (wall,
ceiling, structure, etc.), and the components used for attachment (screw anchors, screws,
brackets not supplied by RCF etc.), which must guarantee the security of the system /
installation over time, also considering, for example, the mechanical vibrations normally
generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless
this possibility is specied in the user manual.
9. RCF S.p.A. strongly recommends this product is only installed by professional qualied
installers (or specialised rms) who can ensure correct installation and certify it according
to the regulations in force.
The entire audio system must comply with the current standards and regulations regarding
electrical systems.
10. SUPPORTS AND TROLLEYS
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution. Sudden stops, excessive pushing force and uneven oors may
cause the assembly to overturn.
11. There are numerous mechanical and electrical factors to be considered when installing
a professional audio system (in addition to those which are strictly acoustic, such as sound
pressure, angles of coverage, frequency response, etc.).
12. HEARING LOSS
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure
level that leads to hearing loss is different from person to person and depends on the
duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic
pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore
necessary to wear ear plugs or protective earphones.
See the technical specications in loudspeaker instruction manuals to know their maximum
sound pressure levels.
To prevent the occurrence of noise on microphone / line signal cables, use screened cables
only and avoid putting them close to:
- Equipment that produces high-intensity electromagnetic elds (for example, high power
transformers)
- Mains cables
- Loudspeaker lines.
- Do not obstruct the ventilation grilles of the unit. Situate this product far from any heat
sources and always ensure adequate air circulation around the ventilation grilles.
- Do not overload this product for a long time.
- Never force the control elements (keys, knobs, etc. ).
- Do not use solvents, alcohol, benzene or other volatile substances for cleaning the
external parts of this product.

DESCRIPTION
ES 3323-II is a mixer-amplifier with 4 mic-line inputs on removable connectors (the
first input also has an XLR socket), a CD/USB – MP3/WMA player and tuner, 2 aux
inputs (one on the rear panel with dual RCA connector, one on the front player with
1/8” jack) for additional external music sources.
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
/ WMA files.
It is also possible to match a ‘Bluetooth’ device (e.g. a mobile phone) to the player.
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 for improving speech intelligibility.
Both the internal music source (CD/USB – MP3/WMA player and tuner) and the rear
panel AUX INPUT have separate tone controls.
Front panel LED’s indicate the device state (ON, PROT), the priority activation (PRIOR)
and the signal level (SIG/PK).
RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
MADE TO GUARANTEE RELIABILITY AND HIGH PERFORMANCE.

REMOTE VOLUME CONTROL
The MASTER and BGM remote volume controls are independent. Insert a potentiometer
between the respective contact and the ground.
The potentiometer nominal value affects the
operating range (referring to the front panel
settings): the higher the value, the wider the
adjustable range.
Its value can be typically from 10 kΩ to 100 kΩ,
the optimal action is obtained with an inverse
logarithmic curve potentiometer, but it is also
acceptable a linear response one.
The music remote control is relative to the activated music source (either internal or
external).
The maximum range that can be obtained is 40 dB (relative to the signal adjusted by the
main settings).
MUSIC SOURCE REMOTE SELECTION
It is obtained by connecting a push-button between the SEL e GND contacts.
The selection is cyclic: CD/USB – MP3 player and tuner, AUX INPUT
21
, no music.
importaNt: iF a remote coNtrol poteNtiometer is Not ForeseeN, it is Necessary to short-
circuit the respective coNtact to grouNd (through a wire), otherwise the master volume

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).
ES 3323 CAN OPERATE IN 3 DIFFERENT MODES:
1. SINGLE: as stand-alone amplier for both paging and music.
The music is not held in zones not paged during a priority event in progress.
2. DUAL AMPLIFICATION ‘A’: ES 3323 is linked to an additional external amplier (i.e.
RCF UP 2321) for paging only (while the internal one amplies the music only).
3. DUAL AMPLIFICATION ‘B’: ES 3323 is linked to an additional external amplier (i.e.
RCF UP 2321) for music only (while the internal one is for paging only).
‘vox’ is aN iNterNal circuit that autoMatically activates the chaNNel 1 priority wheN a sigNal is
detected oN the audio iNput 1.
OPERATION WITH NO PRIORITY EVENT IN PROGRESS
(after turning the amplier on or when a priority command ends).
If no priority command is present (including VOX and SEQUENTIAL COMMAND 29), all
the channels 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 6 control.
The volume of each input 1 ÷ 4 is adjusted separately by the controls 1, 2, 3, 4 1.
The music volume depends on either the control of the CD/USB – MP3 player and tuner (if
selected) or the AUX IN volume control 2 on the front panel.
The AUX INPUT 21 volume also depends on the rear panel GAIN 20 control.
the Music source (iNterNal or exterNal) caN be activated / Muted through the froNt paNel buttoNs

i. If necessary, attenuate the output level of each zone by using its respective attenuator

j. Adjust the channel 1 ÷ 4 volumes 1 if these inputs are connected.
Note: here above it is assuMed that reMote coNtrol poteNtioMeters are Not coNNected or, if
coNNected, these are teMporarily set to their Max. level.
THE PRIORITY COMMAND IS GOT:
- Through channels 1 ÷ 4, by connecting (in the removable connectors
15
) the respective
contact CMD to ground (GND); the priority remains activated if the link is stable (but the
input 2 and 3 SMART function).
- By the channel 1 through its VOX function (if enabled).
- Through BM 3003 / BM3001 paging microphones connected to the ‘RJ’ port
13
of
the channels 2 and 3, considering that removable connectors (for priority commands
and audio signals) cannot be used if lines are engaged (in order to avoid malfunction).
- By the SEQUENTIAL COMMAND
29
.
If any priority command is in progress (including VOX), only the channel with priority (among
inputs 1 ÷ 4, BM 3003 / BM 3001 paging microphones, SEQUENTIAL COMMAND) is sent
to the DIRECT OUTPUTS 34 for loudspeakers.
The selected music source and the other inputs are muted (even on ZONE OUTPUTS 33).
When a priority event is in progress, the ‘PRIOR’ LED 7 gets lit and the audio signal sent
to the PRE OUT 23 only includes the channel with priority.

PRIORITY
A priority command having a higher level
can override the previous one.
The priority levels are:
1. (highest) SEQUENTIAL COMMAND
2. channel 1 (including VOX)
3. channels 2 and 3 (interlocked each other)
4. channel 4
THE PRIORITY MODE (INCLUDING THE VOX FUNCTION) IS SET BY THE DIPSWITCH 3 PRESET
27
:
As soon as a priority event ends, the initial state will be restored (the channels 1, 2, 3, 4
and the selected music source will be mixed together, unless another priority event is in
progress).
About selective paging to A, B, C zones (separated ZONE OUTPUTS
33
), it is necessary
to consider:
- The state of front panel PAGING
10
and GENERAL 9 buttons.
- The setting of the dip-switches 1 and 2 PRESET
27
on the rear panel.
- The device requiring the priority (for instance, BM 3001 paging microphones can make
general calls only, BM 3003 can make selective calls).
The 3 zone attenuators
12
can adjust the level on the separate 70 V / 100 V ZONE OUTPUTS
33
, but the DIRECT OUTPUTS 34 (and the additional external amplier, if present) are
not affected by these controls.
The audio signal of an event with priority and ‘override’ is always sent to the separate
outputs with its. max. set volume, without being controlled by the zone attenuators.
The audio signal level of an event with normal priority is also adjusted by the zone
attenuators.

ENGLISH
THE 3-ZONE SELECTIVE PAGING IS CONTROLLED ACCORDING TO THE
FOLLOWING RULES:
1. If the GENERAL button 9 is on, when the priority is got by one of the channels 1
÷ 4 or a BM3001 paging microphone, paging will be general (‘all call’) in the OVERRIDE
mode (regardless of any other setting).
2. When the priority is got by the channels 2 – 3 (or by a BM 3001 paging microphones
connected to either the input 2 or 3) or the SEQUENTIAL COMMAND 29, paging (/ the
alarm tone) will be general (‘all call’) in the OVERRIDE mode (regardless of any other
setting).
3. From BM 3003 paging microphones (connected to the inputs 2 and 3), users can
always select the zones to be paged (OVERRIDE mode).
4. When the priority is got by the channel 1, paging will be always in the OVERRIDE
mode; the zone selection depends on both the dip-switch 1 of the PRESET group 27 and
the front panel PAGING buttons 10:
- If the DIP 1 is set to ‘PAGING A B C TO IN 4’, paging is always general (regardless of the
PAGING button selection).
- If the DIP 1 is set to ‘IN 1’, paging is selective to the zones chosen through the PAGING
buttons (note: if no zone is selected, paging is only sent to the DIRECT OUTPUTS 34).
5. When the priority is got by the channel 4, paging can be either normal or in the
OVERRIDE mode, according to the dip-switch 2 setting of the PRESET group 27 (and
also the front panel GENERAL button 9). The zone selection depends on both the dipswitch 1 (PRESET group 27 ) and the front panel PAGING buttons 10:
- If the DIP 1 is set to ‘IN 1’, paging is always general (regardless of the PAGING button
selection).
- If the DIP 1 is set to ‘PAGING A B C TO IN 4’, paging is selective to the zones chosen
through the PAGING buttons (note: if no zone is selected, paging is only sent to the
DIRECT OUTPUTS 34).

4 DIP-SWITCH GROUP (PER EACH CHANNEL 1÷4)
For each channel, it is possible to set the input gain (with or without PHANTOM power
supply) on/off, insert / remove the high-pass lter and enable / disable the chime, which is
played on every priority event.
INFORMATION ABOUT THE CHIME
The chime is not played when using the channel 1 VOX function (a priority command is
needed to play the chime).
Its melody can be either short or long (dip-switch 7 of the PRESET group

When the chime is playing (a few seconds), in the single mode operation, the music
(internal or external through the AUX INPUT) is muted.
SETTING AUTOMATIC STORE
All settings by the front panel buttons are automatically stored after 10 seconds since the
last button pressure.
If a priority event is in progress, it is possible to change the state of each single button
(by pressing it), but the respective effect will be actually applied and stored only when the
priority event ends.

RCF BM 3001 / BM 3003 PAGING MICROPHONES
RCF BM 3001 / BM 3003 PAGING MICROPHONES
Channels 2 and 3 have an input with RJ 45 socket, to which it is possible to connect 2
models of RCF paging microphones (not included):
- BM 3001 (for all calls only)
- BM 3003 (for 3-zone selective calls and ‘daisy-chain’ links of up to 12 paging
microphones in the same line).
Only one BM 3001 paging microphone can be connected to each RJ 45 input (max. 2:
one to the input 2, one to the input 3).
The BM 3001 operating mode and its priority depends on settings previously described.
it is possible to assigN the sMart fuNctioN to each bM3001 pagiNg MicrophoNe through the dip-
switches 5 (for the iNput 2) aNd 6 (for the iNput 3) of the preset group
27
.
ES 3323-II identies a BM3001 paging microphone through the ‘LINE with PHANTOM’
mode setting in the respective channel, therefore it is necessary to set the input dipswitches 3 and 4
16
properly (both set to ON).
WHEN USING BM3003 PAGING MICROPHONES, TO EACH RJ 45 IT IS POSSIBLE
TO CONNECT:
- a single BM 3003 paging microphone (without any additional power supply unit)
- a ‘daisy-chain’ made of max.12 BM 3003 by inserting an additional power supply unit.
After connecting one or more BM 3003 paging microphones, set the dip-switches
3 and 4
16
of the respective input to the ‘LINE’ mode (both set to OFF).
BM 3003 paging microphones always operate in the SMART mode, so set (/ leave) the
dip-switch 5 (for the input 2) and 6 (for the input 3) of the PRESET group
27
(SMART
function) to OFF.
IT IS POSSIBLE TO CONNECT A BM 3001 TO AN RJ 45 INPUT AND ONE (OR
MORE) BM 3003 TO THE OTHER, SO IT IS ALLOWED TO HAVE:
- No paging microphone
- 1 x BM 3001
- 2 x BM 3001 (one per each input)
- max. 12 x BM 3003 (to one input only)
- max. 12 x BM 3003 (to an input) + 1 x BM 3001 (to the other input)
- max. 24 x BM 3003 (max. 12 per each input).
importaNt: it is Not allowed to coNNect diFFereNt pagiNg microphoNe models to the
same iNput!
When BM 3003 paging microphones are linked (daisy-chain) in the same line, the rst
BM 3003 (that is directly connected to the ES 3323 amplier) does not need to be
powered by the additional power supply unit, which is necessary for all the others.
About paging microphone operation in details, refer to the respective user manuals.
When the chime is playing (if enabled), microphones are momentary muted.
Paging microphones can be disabled by events having a higher priority level than their
channels (2 and 3).
