The BMA-MAT4120 is a 4 channel mixer amplifier with four power outputs of 120W.
The inputs and outputs can be matrix selected, thus it is a high integrated 4 channel audio matrix system solution with Mp3 player for hotel, shopping mall, sports center,entertainment center, etc.
Each inputs could be easily designed to different four zones by front panel selector, moreover each inputs are supplied with separate bass, treble and volume control for precise sound effect for each area.
Three Combo Mic/Line inputs with selector and phantom power, thus the microphone input support both phone jack and XLR type. Two RCA type line inputs, built-in Mp3 player on front panel, one tel input and one RJ45 port for a remote paging microphone BPC-4.
A RS232 serial communication port is supplied for third party system communication. A priority input could be used to override all other inputs. A monitor is also built-in for in room monitoring use. 4 channel separate line inputs and speaker outputs are provided for easy wiring. 70V, 100V and 4 Ω speaker outputs all are supplied for versatile sound loudspeaker matching. Extensive protection functions from thermal, short-circuit, clip and Overload. FEATURES
