Frequently Asked Questions - ES 2160 RCF

How do I change the power supply voltage between 115V and 230V?

Disconnect the mains, remove the lid, locate the voltage change connector, set it to the desired position (230Vac or 115Vac) as indicated on the PCB, refit the lid, and replace the fuse with the correct rating for the new voltage.

Can I connect both 100V line and 4Ω speakers at the same time?

No, use only one output type at a time. Connecting both simultaneously will overload the amplifier.

How do I pair a Bluetooth device?

Ensure antenna is connected, enable Bluetooth on your device, press the BT PAIR ON/OFF button (LED flashes blue/red), search for ES2160 from your device, and pair. Audio will stream automatically.

What is the VOX function and how do I enable it?

VOX automatically activates priority on input 1 when a signal is detected. To enable, set DIP switch #4 in the PRESET group to VOX ON IN1.

How do I set the priority mode?

Use DIP switches #2 and #3 in the PRESET group. Options: Interlocked (only one priority at a time) or Graduated (higher priority overrides lower). Switch #2 selects which input has highest priority (IN1 or IN2).

How do I connect an RCF BM 3001 paging microphone?

Connect the microphone to RJ45 socket on input 2 or 3. Set the corresponding input DIP switches: #3 to PHANTOM, #4 to -20 dBu. The microphone will have priority capabilities.

Why is the MP3 player not playing from USB/SD?

Ensure the file format is MP3 with .mp3 extension. USB/SD must be formatted FAT12/16/32. Do not insert both USB and SD simultaneously. Max capacity 32 GB.

How do I adjust the chime volume?

Use the CHIME LEVEL trimmer (small screwdriver) on the rear panel. The chime type (short/long) is set via PRESET DIP switch #7.

What does the SIG/PK LED indicate?

Green: signal > -15 dB; Green+Red: signal 0 to +2 dB (optimal); Red (peak): signal ≥ +3 dB. Reduce master volume if red is continuous to avoid overload.

How do I clean the device?

Use a dry cloth only. Do not use solvents, alcohol, or abrasive cleaners. Clean only when power is off.

DESCRIPTION

ES 2160 is a 160 W mixer-amplifier, with 4 mic-line audio inputs on removable connectors (the first input has also an XLR socket), an MP3 player with Bluetooth and an aux input for a music source (i.e. CD players, tuners, etc.).

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 a single RCF BM 3001 paging microphone (through CAT5 cable).

The amplifier output is available either for low impedance speakers (min. 4 Ω) or 100 – 70 V constant voltage line (for speakers having 100 – 70 V transformers).

The MUSIC ON HOLD output directly sends the internal MP3 player signal to additional amplifiers, mixers, phone systems ('music on hold' function), etc. .

The PRE OUT output sends the signal (the same mix routed to the internal amplifier) to additional amplifiers.

The 4 mic.-line inputs have a common PRESENCE control and separate high-pass filters that are useful for improving speech intelligibility.

The internal MP3 player and the AUX INPUT have common tone controls.

Front panel LEDs indicate the device state (ON, PROT), priority circuit enabled (PRIOR) and the signal level / peak (SIG/PK).

FRONT PANEL

[1] Volume controls for each universal input (1, 2, 3, 4).

Note: unused input volume controls should always be turned fully counter clockwise (to 0).

[2] MP3 PLAYER [8] and AUX INPUT [14] volume control.
[3] AUX button (with LED). Press to turn on (the LED is lit) the AUX INPUT [14] (on the rear panel), which signal is sent to the internal amplifier (and also PRE OUT [18]). If activated, the internal MP3 player will be muted (the MP3 button LED will turn off).
[4] MP3 button (with LED). Press to turn on (the LED is lit) the MP3 player, which signal is sent to the internal amplifier (and also MUSIC ON HOLD [19] and PRE OUT [18] outputs). If activated, the AUX INPUT [14] on the rear panel will be muted (the AUX button LED will turn off).

The MP3 player signal is always sent to the MUSIC ON HOLD [19] output (that is not affected by the volume control and MP3 / AUX buttons).

[5] Internal amplifier MASTER volume control. Note: the audio outputs having RCA connectors (MUSIC ON HOLD [19] and PRE OUT [18]) 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 VOX function or an universal input or SEQ. CHIME CMD
Sig/Pk	Green the signal level is higher than - 15 dB
	Green + Red the signal level is in the 0 ÷ +2 dB range
	Red (peak) 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 input volume where a too high signal is present) when the SIG/PK LED is continuously indicating red.

[7] Main POWER switch (0 = off; 1 = on)
[8] MP3 PLAYER with Bluetooth (see the respective manual section).

REAR PANEL

[9] Four balanced audio inputs (1, 2, 3, 4) with sockets for removable connectors.

[15] GAIN AUX: AUX INPUT gain control.
[16] GAIN MP3: MP3 player gain control.
[17] TREBLE and BASS controls for both the internal MP3 player and the AUX INPUT.
[18] PRE OUT audio output (with RCA connector) that sends the same signal routed to the internal amplifier (signal that can be either a single source with priority or the mix of all the four inputs and either the internal MP3 player or the AUX INPUT).

Use PRE OUT to connect additional external amplifiers.

[19] MUSIC ON HOLD audio output (with RCA connector) that sends the internal MP3 audio signal (mono).

The MUSIC ON HOLD output is not affected by any volume control, nor a switch, and can be linked to a telephone system (in order to get the 'Music On Hold' function).

[20] 8 dip-switches PRESET to set the priority options:

1	MIX – MUSIC OFF	MIX: the MP3 player or the AUX INPUT is always present in the mix sent to the amplifier, even during a priority command.	MUSIC OFF: the MP3 player or the AUX INPUT is not sent to the amplifier during a priority command.
2	PR. IN1 – PR. IN2	PR. IN1: the input 1 has the highest priority level with override (but the SEQUENTIAL CHIME CMD.) through the relevant command (or VOX), if the dip-switch no.3 has been set to 'graduated priority'.	PR. IN2: the input 2 has the highest priority level with override (but the SEQUENTIAL CHIME CMD.) through the relevant command, if the dip-switch no.3 has been set to 'graduated priority'.
3	I/LCK – GR. PRIOR.	I/LCK: interlocked priority mode (read the 'Amplifier operation' section).	GR. PRIOR.: graduated priority mode (read the 'Amplifier operation' section).
4	OFF – VOX ON IN1	OFF: the channel 1 VOX function is off.	VOX ON IN1: the input 1 VOX function is turned on (automatic priority when a signal is detected).
5	OFF – SMART IN2	OFF: the input 2 priority is kept only if the relevant command is still present ('push' mode).	SMART IN2: the input 2 priority is switched on / off by every impulse of the relevant command ('toggle' mode).
6	OFF – SMART IN3	OFF: the input 3 priority is kept only if the relevant command is still present ('push' mode).	SMART IN3: the input 3 priority is switched on / off by every impulse of the relevant command ('toggle' mode).
7	SHORT – CHIME LONG	SHORT: short chime (before paging). CHIME LONG	G: long chime (before paging).
8	SHORT – SEQ. CHIME LONG	SHORT: the short chime is continuously played when the SEQUENTIAL CHIME CMD. is activated.	CHIME LONG: the long chime is continuously played when the SEQUENTIAL CHIME CMD. is activated.

[21] CHIME LEVEL (a trimmer adjustable by using a small screwdriver).

2. When Bluetooth external device is playing and then disconnected, audio source won't do any switch automatically, and it will be needed to select the MP3 source with SOURCE button.
3. When a MP3 source is playing and a Bluetooth device is connected, music will be switched to BT.

NOTES ABOUT MP3 FILES

• MP3: means MPEG Audio Layer 3 and refers to an audio compression type.
• This player reads MP3 files on USB flash drives and SD cards.
• The file extension must be .mp3.
• The max. directory (/ folder) level is 8, including the 'root'.
• It is advisable to use MP3 files having a sampling frequency of 44.1 kHz and a fixed bit-rate of at least 128 kbps (if higher, for instance 192 kbps, the sound quality will be better).
• The player may not play MP3 files in the order as written on the USB flash drive / SD CARD.

BLUETOOTH DEVICES

'Bluetooth' is a wireless technology standard for exchanging data over short distances from fixed and mobile devices (e.g. cellular phones).

The MP3 player includes a Bluetooth interface to receive audio signals from compatible external devices, which must have A2DP technology ('Advanced Audio Distribution Profile').

To connect your Bluetooth external device to the MP3 player:

1. Check if the antenna [26] on the rear panel is properly connected and oriented.
2. Enable 'Bluetooth' on the external device.
3. Push the MP3 player BT PAIR ON/OFF button [35] (its LED now flashes blue / red).
4. Within a minute, on the external device, start searching other devices with active Bluetooth; ES2160 should be displayed.
5. Pair the external device and ES 2160.
6. Start the audio playback on the external device (which should be now included in the available sources of the internal MP3 player).

When turning ES 2160 on, the MP3 player automatically tries to connect (via 'Bluetooth') to the last paired external device (if available).

AMPLIFIER OPERATION

'VOX' is an internal circuit that automatically activates the input 1 priority when a signal is detected on its sockets.

Power on (or when a priority command ends)

If no priority command is present (including VOX and SEQUENTIAL CHIME COMMAND), all the inputs 1, 2, 3, 4 and the MP3 PLAYER (or the AUX INPUT) are mixed together.

The music volume (either the MP3 PLAYER or the AUX INPUT source) depends on the front panel volume control [2] and also the respective GAIN control settings ( [15] or [16] ) on the rear panel.

Priority

If a priority command is present (or VOX), the MP3 PLAYER (or the AUX INPUT) can be either included in the mix sent to the amplifier or muted, according to dip-switch no.1 setting (see [20] : the eight dip-switch group).

During a priority command ('PRIOR' LED turns on), only the audio signal of the channel with priority (and the MP3 PLAYER / AUX INPUT, if enabled) is sent to the amplifier (and the PRE OUT output).

The MP3 PLAYER (or the AUX INPUT) is always muted in the mix 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 eight dip-switch group (see [20]):

DIP 2 DIP 3 MODE
---- I/LCK INTERLOCKED			Only the first priority command of inputs 1 to 4 (and also channel 1 VOX, if enabled through the dip-switch no.4) is accepted.Any other later 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 SEQUENTIAL CHIME CMD. .
PRIO IN1 GR. PRIOR.		GRADUATED PRIORITY 1GRADUATED PRIORITY 2	A priority command having a higher level can override the previous one. The priority levels are:1. (highest) SEQUENTIAL CHIME CMD.2. input 1 (including VOX)3. input 24. input 35. input 4
PRIO IN2 GR. PRIOR.			A priority command having a higher level can override the previous one. The priority levels are:1. (highest) SEQUENTIAL CHIME CMD.2. input 23. input 1 (including VOX)4. input 35. input 4

The dip-switch no.2 (8 dip-switch group) allows you to switch the priority level between the inputs 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 (all the inputs 1, 2, 3, 4, the MP3 PLAYER or the AUX INPUT will be mixed together, unless another priority event is in progress).

Sequential Chime Cmd.

The SEQUENTIAL CHIME COMMAND makes the chime (either short or long, depending on the dip-switch no.8 setting, see [20] ) be continuously played. This command has the highest priority level and always mutes the MP3 player (or the aux input) in the mix sent to the amplifier.

Channel 2 - 3 'push' / 'toggle' priority mode

The dip-switches no.5 and no.6 (eight dip-switch group, see [20]) allow the choice of the priority mode for inputs 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 (one per each input 1 to 4)

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

It is also possible to turn the PHANTOM power supply on/off, to insert or remove the high-pass filter and to enable or 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 eight dip-switch group, see [20]).

During the chime playback (a few seconds), the MP3 player (or the AUX INPUT) is not sent to the amplifier.

RCF BM 3001 paging microphone (not included)

Both inputs 2 and 3 have an RJ 45 socket, to which a single BM 3001 paging microphone 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], the second table).

When the BM 3001 paging microphone is on (ready to talk), its LED turns ON.

During the chime playback (if the 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 input 2 or 3, to which the paging microphone is connected).

SPEAKERS CONNECTION

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

100 / 70 V CONSTANT VOLTAGE OUTPUTS

• Each speaker shall have a line transformer with the input voltage equal to the line voltage (100 / 70 V).
• The speaker total power shall not be higher than the amplifier maximum power (160 W).

POWER OUTPUT

LOW IMPEDANCE OUTPUT (4 Ω)

• The speaker 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.
• Speaker models shall be chosen by considering the maximum power (160 W) that the amplifier can deliver.
• Speaker line should be as short as possible, as 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 (100V or 70V), as this overloads the amplifier.

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 amplifier is not connected to the mains (unplug the power cord).
• Remove the lid.

The voltage change connector is highlighted by a square.

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

Refit the amplifier lid.

Before connecting the amplifier 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).
