IMPORTANT NOTES

WARNING

1. 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.

1. 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.

1. 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.).

2. 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 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).

• Mains cables.

• Loudspeaker lines.

OPERATING PRECAUTIONS

• 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.

IMPORTANT NOTES

OPERATING PRECAUTIONS

RCF S.p.A. would like to thank you for having purchased this product, which has been designed to guarantee reliability and high performance.

AM 2160 and AM 2320 are mixer-amplifiers with 4 mic-line audio inputs on removable connectors (the first input also has an XLR socket) and 2 aux inputs for music sources (e.g. CD players, tuners, etc.).

Both the models have identical features, but the nominal power: AM 2160 is a 160 W amplifier; AM 2320 is a 320 W amplifier.

The amplifier output is available either for low impedance loudspeakers (min. 4 Ω) or 100 - 70 V constant voltage line (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).

The MUSIC ON HOLD aux output allows to send the music (the output signal of the device connected to the AUX INPUT A) 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.

The 2 aux inputs have independent tone controls (common for both aux inputs).

Front panel LED's indicate the device state (ON, PROT), the priority activation (PRIOR) and the signal level (SIG/PK).

FRONT PANEL

1VOLUME CONTROLS FOR EACH UNIVERSAL INPUT (1, 2, 3, 4).

Note: unused channels should always be turned counterclockwise (to 0).

2UX INPUT VOLUME CONTROL.

Note: turn counterclockwise (to 0) if aux inputs are not used.

3UX A BUTTON (with LED).

It turns on (LED is lit) / off the AUX INPUT A to the internal amplifier (and PRE OUT).

If activated, the AUX INPUT B signal will not be sent to the internal amplifier (the AUX B button LED will turn off).

The AUX INPUT A signal is always sent to the MUSIC ON HOLD output (that is not affected by the AUX A and AUX B buttons).

4UXB BUTTON (WITHLED).

It turns on (LED is lit) / off the AUX INPUT B to the internal amplifier (and PRE OUT).

If activated, the AUX INPUT A signal will not be sent to the internal amplifier (the AUX A button LED will turn off).

It takes 10 seconds (after pressing either the AUX A or the AUX B button) to store on its memory the last selection.

5 INTERNAL AMPLIFIER MASTER VOLUME CONTROL.

Note: the audio outputs having RCA connectors (MUSIC ON HOLD and PRE OUT) are not affected by the MASTER volume control.

6 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

10 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.

PAGING RELAY 24 V - 500 mA max

OPERATION

Vox' is an internal circuit that automatically activates the channel 1 priority when a signal is detected on the audio INPUT 1.
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).

1 The selected aux input is always excluded from the signal sent to the amplifier when the CHIMESEQUENTIAL 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):

POWER ON (OR WHEN

A PRIORITY COMMAND ENDS)

DIP 2 DIP3 MODE

...I/LCK 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 can override a previous priority) is the CHIME SEQUEN COMMAND.

PRIO IN1

GR. PRIOR.

GRADUATED PRIORITY 1

A priority command having a higher level can override the previous one.

The priority levels are:

1. (highest) CHIMESEQUENTIAL COMMAND
2. channel 1 (including VOX)
3. channel 2
4. channel 3
5. channel 4

PRIO IN2

GR. PRIOR.

GRADUATED PRIORITY 2

A priority command having a higher level can override the previous one.

The priority levels are:

1. (highest) CHIME SEQUENTIAL COMMAND
2. channel 2
3. channel 1 (including VOX)
4. channel 3
5. channel 4

1 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 aux input will be mixed together, unless another priority event is in progress).

The chime sequential command makes the chime (short or long, depending on the dip-switch no.8 setting, see 20) be continuously repeated. This command has the highest priority level and always removes the selected aux input from the signal sent to the amplifier.

The dip-switches no.5 and no.6 (8 dip-switch group, see 20) 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).

Each input gain can be set to either MIC or -20 dBu (0 dBu for the channel 1). 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.

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 20).

When the chime is playing (a few seconds), the selected aux input is not sent to the amplifier.

Channels 2 and 3 have an input with RJ 45 socket, to which a BM 3001 paging microphone

INFORMATION

ABOUT THE CHIME

can be connected (note: it is necessary to set the dip-switches no.3 and no.4 to the '-20 dBu + PHANTOM' mode, see 10, 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).

LOUDSPEAKER CONNECTION

Use 1 output only, DO NOT MIX 100/70 V and 4 Ω CONNECTIONS!

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

The loudspeaker total impedance shall not be lower than 4 .Note: a total impedance equal to 4 allows the amplifier maximum power delivery. A higher impedance leads to a reduction of the power delivered by the amplifier (e.g. 8 : approx. 12 power, 16 : approx. 14 power). An impedance lower than 4 overloads the amplifier.
- Loudspeaker models shall be chosen by considering the max. power (AM 2160: 160 W on a 4 Ω load; AM 2320: 320 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) and the constant voltage output (70V or 100V), as this overloads the amplifier.

LOW IMPEDANCE OUTPUT (4 Ω)

IMPORTANT: This manual section is for 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 voltage change connector is highlighted by a square.

If the mains voltage is 230V set the connector to the 230Vac position (see the picture 2), according to the PCB indication (looking at the connector front, the central pin is connected to the right one).

If the mains voltage is 115V set the connector to the 115 Vac position (see the picture 3), according to the PCB indication (looking at the connector front, the central pin is connected to the left one).

Refit 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 25) is the correct current rating for the mains voltages (read the fuse indication below the connector).
