RCF ES 3160-II CD-USB-Bluetooth/MP3 Digital Receiver Amplifier

The ES 3160-II CD-USB-Bluetooth/MP3 Digital Receiver Amplifier from RCF is a mixer-amplifier with 4 mic-line audio inputs on removable connectors (the first input also has an XLR socket), CD-USB/Bluetooth/MP3 player and tuner, and an aux input for an additional external music source. The amplifier’s nominal power is 160W, available on either a low-impedance output (minimum 4 Ohms) or 100 or 70V constant voltage output (for loudspeakers having 100 or 70V transformers). Input 1 has a signal detection circuit (VOX) providing automatic priority operation.

All the four inputs can access the priority through an external command (connected to the removable connector). Inputs 2 and 3 also have an RJ45 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 LEDs indicate the device state (ON, PROT), priority activation (PRIOR), and signal level (SIG/PK).
