ES3160

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, 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 highpass 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 LEDs indicate the device state (ON, PROT), the priority activation (PRIOR) and the signal level (SIG/PK).
