RCF S.p.A. thanks you for purchasing this product, which has been designed to guarantee

reliability and high performances.

DESCRIPTION

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

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 aux inputs are not used.

3 AUX 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).
