This apparatus shall not be exposed to dripping or splashing. No objects filled with liquid, such as vases, shall be placed on this apparatus. No naked sources (such as lighted candles) should be placed on this apparatus.

4. Never attempt to carry out any operations, modifications or repairs that are not expressly

described in this manual. Contact your authorized service centre or qualified personnel should any of the following occur:

• The product does not function (or functions in an anomalous way).

• The power supply cable has been damaged.

• Objects or liquids have got into the unit.

• The product has been subject to a heavy impact.

5. If this product is not used for a long period, disconnect the power cable.

6. If this product begins emitting any strange odours or smoke, switch it off immediately and

disconnect the power supply cable.

7. The terminals marked with the symbol

are HAZARDOUS LIVE and their connection is to be made by an INSTRUCTED PERSON or the use of ready-made cables is required.

8. Do not connect this product to any equipment or accessories not foreseen.

For suspended installation, only use the dedicated anchoring points and do not try to hang this product by using elements that are unsuitable or not specific for this purpose. Also check the suitability of the support surface to which the product is anchored (wall, ceiling, IMPORTANT28 ENGLISH 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 specified in the user manual.

9. RCF S.p.A. strongly recommends this product is only installed by professional qualified installers (or

specialised firms) 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 floors 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.).

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 specifications in loudspeaker instruction manuals to know their maximum sound pressure levels. IMPORTANT NOTES 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 fields (for example, high power transformers)

• 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.29 ENGLISH RCF S.p.A. thanks you for purchasing this product, which has been designed to guarantee reliability and high performances. DESCRIPTION ES 3160 is a mixer-amplifier with 4 mic-line audio inputs on removable connectors (the first input also has an XLR socket), CD/USB – MP3 player and tuner and an aux input for an additional external music source.The amplifier nominal power is 160 W, available on either a low impedance output (min. 4 Ω) or 100 – 70 V constant voltage output (for loudspeakers having 100 – 70 V transformers).Input 1 has a signal detection circuit (‘VOX’) providing automatic priority operation.All inputs 1, 2, 3 and 4 can access the priority through an external command (connected to the removable connector). Inputs 2 and 3 also have an RJ 45 socket for quick connection of an RCF BM 3001 paging microphone (through CAT5 cable).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 for improving speech intelligibility.Both the internal music source (CD/USB – MP3 player and tuner) and the 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). FRONT PANEL 1 Volume controls for each universal input (1, 2, 3, 4) Note: unused channels should always be turned counterclockwise (to 0). 2 AUX INPUT volume control Note: turn counterclockwise (to 0) if the aux input is not used.

ENGLISH 3 AUX IN button (with LED) It turns on (LED is lit) / off the AUX INPUT to the internal amplifier (and PRE OUT). If activated, the CD/USB – MP3 player / tuner signal will not be sent to the internal amplifier (the INTERNAL button LED will turn off).

The AUX INPUT signal is always sent to the MUSIC ON HOLD output (that is not affected by the AUX IN button). 4 INTERNAL button (with LED) It turns on (LED is lit) / off the CD/USB - MP3 player / tuner to the internal amplifier (and PRE OUT). If activated, the AUX INPUT signal will not be sent to the internal amplifier (the AUX IN button LED will turn off).

The CD/USB MP3 player / tuner signal is always sent to the INTERNAL PROGRAM output (that is not affected by the INTERNAL button).

It takes 10 seconds (after pressing either the AUX IN or INTERNAL button) to store on its memory the last selection. 5 CD/USB – MP3 player and tuner (read the relevant manual section at page 36). 6 Internal amplifier MASTER volume control Note: all audio outputs via RCA connectors (INTERNAL PROGRAM, MUSIC ON HOLD, PRE OUT) are not affected by the MASTER volume control. 7 LEDs ON green: the device is switched on PROT red: overload protection orange: thermal protection PRIOR yellow: priority by either the VOX function or an universal input or the SEQ. COMMAND. SIG/PK green: the signal level is higher than – 15 dB green + red: the signal level is in the 0 ÷ +2 dB range red: the signal level is equal or higher than +3 dB

0 dB = signal level that allows to get the amplifier maximum power.

The internal ‘limiter’ circuit helps to avoid the amplifier overloading, yet it is advisable to reduce the MASTER volume (or a single channel volume where a ‘too high’ signal is present) when the SIG/PK LED is continuously indicating red. 8 Main POWER switch (0 = off; I = on)31 ENGLISH REAR PANEL 9 2 RJ 45 sockets (channels 2 and 3) to connect 1 RCF BM 3001 paging microphone per socket.

Either the MUSIC ON HOLD output (if an external music source has been connected to the AUX INPUT) or the INTERNAL PROGRAM output can be used for the connection to a telephone system (in order to have the ‘music on hold’ function).33 ENGLISH

MIX: the music source (internal or external) is always present in the (mixed) signal sent to the amplifier, even during a priority command. MUSIC OFF: the music source (internal or external) is not sent to the amplifier during a priority command.

PRIO INPUT 1 PRIO INPUT 2 PRIO INPUT 1: the channel 1 has the highest priority level with override (but the CHIME SEQUENTIAL COMMAND) through the relevant command (or VOX), if the dip-switch no.3 has been set to ‘graduated priority’. PRIO INPUT 2: the channel 2 has the highest priority level with override (but the CHIME SEQUENTIAL COMMAND) through the relevant command, if the dip-switch no.3 has been set to ‘graduated priority’.

OFF: the channel 1 VOX function is off. VOX ON INPUT 1: the channel 1 VOX function is on (automatic priority when a signal is detected on the audio INPUT 1).

OFF SMART INPUT 2 OFF: the channel 2 priority is kept only if the relevant command is still present (‘push’ mode). SMART INPUT 2: the channel 2 priority is switched on / off by every impulse of the relevant command (‘toggle’ mode).

OFF SMART INPUT 3 OFF: the channel 3 priority is kept only if the relevant command is still present (‘push’ mode). SMART INPUT 3: the channel 3 priority is switched on / off by every impulse of the relevant command (‘toggle’ mode).

CHIME: the chime (selected by the dip- switch no.7) is continuously played when the ‘CHIME SEQUENTIAL COMMAND’ is activated. SIREN ON SEQ.CMD: an alarm tone is sent when the ‘CHIME SEQUENTIAL COMMAND’ is activated. o 8 dip-switches PRESET to set the priority options:34 ENGLISH p CHIME LEVEL (a trimmer adjustable by using a small screwdriver). [ CHIME SEQUENTIAL COMMAND with removable connector (activated when the 2 pins are short-circuited) to send either the chime continuously (the chime type can be selected by the dip-switch no.7, see 21-7) or an alarm tone.

If the dip-switch no.8 is set to “SIREN ON SEQ.CMD”, the alarm tone will have the maximum volume level (adjustable by the MASTER volume only). ] Internal relay contacts (3 pole removable connector). The internal relays switches when a priority command is present.

Max. voltage: 24 V; max. current: 0.5 A A Amplifier output (max. 160 W) to loudspeakers (100 / 70 V constant voltage line – 4 Ω impedance). Use ONE output only (read the section ‘Loudspeaker connection’). S 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 music source are mixed together. The music source can be:

• The internal CD/USB – MP3 player and tuner.

The music volume depends on either the CD/USB – MP3 player / tuner VOL control (if selected) or the AUX IN volume control on the front panel (see 2). AUX INPUT level also depends on the relevant GAIN control setting (see 16) on the rear panel.

The music source (internal or external) can be activated / muted through the front panel buttons (see 3 and 4).

INTERLOCKED INTERLOCKED Only the first priority command of channels 1÷4 (and also channel 1 VOX, if enabled through the dip-switch no.4) is accepted. Any other priority command will not be accepted until the previous is removed. Note: the only event that can always be activated later (and override a previous priority) is the CHIME SEQUENTIAL COMMAND. PRIO INPUT 1 GRADUATED PRIOR. GRADUATED PRIORITY 1 A priority command having a higher level can override the previous one. The priority levels are:

1. (highest) CHIME SEQUENTIAL COMMAND

2. channel 1 (including VOX)

PRIO INPUT 2 GRADUATED PRIOR. GRADUATED PRIORITY 2 A priority command having a higher level can override the previous one. The priority levels are:

3. channel 1 (including VOX)

The dip-switch no.2 (8 dip-switch group) allows you to switch the priority level between the channels 1 and 2. This setting does not work in the interlocked priority mode. 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).

“CHIME SEQUENTIAL COMMAND”

The CHIME SEQUENTIAL COMMAND either makes the chime (short or long, depending on the dip-switch no.7 setting, see 21) be continuously repeated or starts the alarm tone (option set by the dip-switch no.8, see 21). This command has the highest priority level and always removes the music from the signal sent to the amplifier. PRIORITY If a priority command is present (or VOX), the music source can be either included in the mixed signal sent to the amplifier or excluded, according to dip-switch no.1 setting (see 21: the 8 dip- switch group). During a priority command (‘PRIOR’ LED turns on), only the audio signal of the channel with priority (and the music, if turned on) is sent to the amplifier (and the PRE OUT output).

The music source 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 21):36 ENGLISH When the chime is playing (a few seconds), the (internal / external) music source is removed from the signal sent to the amplifier. RCF BM 3001 PAGING MICROPHONE (NOT INCLUDED) Channels 2 and 3 have an input with RJ 45 socket, to which a BM 3001 paging microphone can be connected (note: it is necessary to set the dip-switches no.3 and no.4 to the “MIC with PHANTOM” mode, see 12, second table).

When the BM 3001 paging microphone is on (ready to talk), its LED turns ON. When the chime is playing (if chime is enabled), the BM 3001 microphone is momentarily muted. The paging microphone priority mode depends on the settings mentioned above. The paging microphone is muted by events having a higher priority level (than the channel 2 or 3, to which the paging microphone is connected).

CHANNEL 2 - 3 ‘PUSH’ / ‘TOGGLE’ PRIORITY MODE

The dip-switches no.5 and no.6 (8 dip-switch group, see 21) allow choice of priority mode for channels 2 and 3 between ‘push’ (the priority is kept only if the command is still present) and ‘toggle’ (the priority is switched on / off by every impulse of the command). Note: the chosen priority mode is applied to both BM 3001 paging microphones (if present) and priority commands (of removable connectors). 4 DIP-SWITCH GROUP (PER EACH CHANNEL 1÷4) Each input gain can be set to either MIC or LINE. It is also possible to turn the PHANTOM power supply on/off, to insert / remove the high-pass filter and to 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 no.7 of the 8 dip-switch group, see 21).37 ENGLISH FRONT PANEL 1 CD/USB – MP3 PLAYER / TUNER power on / off button. 2 SRC (source) button: source selection among tuner, CD (when inserted), USB (if a USB flash drive is present). 3 FM/AM button: tuner band selection between FM (frequency modulation, 3 groups: FM1, FM2, FM3) and AM (medium wave amplitude modulation, 2 groups: MW1, MW2). 4 DISP (display) button: it sequentially changes the (available) information on the display:

— DOCUMENT (documentary) r TA/AF (traffic announcements / alternative frequency) button (FM tuner only) Some radio stations with RDS (‘Radio Data System’) service periodically provide traffic information. These stations can be identified by the TP indication on the display. If this button is pushed and immediately released:

• When tuned to a radio station that provides traffic information, it will enable (TA is displayed) or disable the traffic information reception mode that has a particular preset volume (read the ‘FUNCTION MENU’ section).

• When tuned to a radio station that does not provide traffic information, according to the setting of the FUNCTION MENU TA parameter, it will start the automatic search of a station providing traffic information (TA SEEK is displayed) or it will be just displayed that this service is not currently available (NO TA/TP).

If the TA (traffic announcements) function is enabled, the band scan (either manual by pushing the SEEK button or automatic by pushing the AMS button), will consider the radio stations broadcasting the TP (traffic programme) identification code only. If this button is pushed and held for a few seconds, the ‘alternative frequency’ function turns on (AF is displayed) / off. This function (when enabled) allows the automatic search of an alternative station having a similar programme to the one selected when the signal reception degrades.

If the alternative frequency function is not available, the AF indication on the display will blink.41 ENGLISH

EON (enhanced other networks) If EON data are received (EON is displayed), TA and AF functions will be enhanced:

70 / 100 V CONSTANT VOLTAGE OUTPUTS

• Each loudspeaker shall have a line transformer with the input voltage equal to the line voltage (70 / 100 V).
• The loudspeaker total power shall not be higher than the amplifier maximum power. LOW IMPEDANCE OUTPUT (4 Ω)

• The loudspeaker total impedance shall not be lower than 4 Ω. Note: a total impedance equal to 4 Ω allows the amplifier maximum power delivery. A higher impedance leads to a reduction of the power delivered by the amplifier (e.g. 8 Ω: approx. ½ power, 16 Ω: approx. ¼ power). An impedance lower than 4 Ω overloads the amplifier.
• Loudspeaker models shall be chosen by considering the max. power (160 W on a 4 Ω load) that the amplifier can deliver.
• Loudspeaker line should be as short as possible, long cables may need large wire cross-sections.
• Do not use, at the same time, both the low impedance output (4 Ω) and the constant voltage output (70V or 100V), as this overloads the amplifier.100V0POWER OUTPUT100V70VCOM100V0 100V070V0POWER OUTPUT100V70VCOM70V0 70V0 100 V 70 V POWER OUTPUT 100V70VCOM45 ENGLISH

POWER SUPPLY VOLTAGE CHANGE

IMPORTANT: This manual section concerns qualified personnel only. The following instructions are to be ignored by the user. Make sure the device is not connected to the mains (unplug the power supply cable). Remove the lid. The power supply circuit is under the ventilation screen (see picture 1), which can be removed by unscrewing the 2 screws. The voltage change connector is highlighted by a square. If the mains voltage is 230 V, set the connector to the 230Vac position (see the picture 3), according to the PCB indication (looking at the connector front, the central pin is connected to the right one). If the mains voltage is 115 V, set the connector to the 115 Vac position (see the picture 4), according to the PCB indication (looking at the connector front, the central pin is connected to the left one). Refit the power supply circuit metallic screen and the device lid. Before connecting the device to the mains, make sure that the fuse (inside the IEC power supply connector of the rear panel, see 26) is the correct current rating for the mains voltages (read the fuse indication below the connector).
