Multi-zone amplifiers with 2 microphone inputs and a switchable stereo input for each zone. An inbuilt media player section offers playback of mp3 audio tracks from USB drive or SD card and also has a B/T wireless receiver and FM radio tuner. A rotary switch for each output zone selects the stereo playback audio from a choice of 2 rear stereo inputs, a front 3.5mm stereo input or the built-in media player. Mic inputs 1 and 2 are live to all output zones at all times. Speakers are connected from the rear panel Euroblock terminals to deliver up to 200W per output at 4 Ohms. Designed for installations requiring high quality stereo sound in multiple rooms or listening areas.Power supply[tab]230Vac, 50Hz (IEC)[br]Fuse[tab]F5A, 250V[br]Amplifier : construction[tab]Class D[br]Frequency response[tab]20Hz - 20kHz ±0.5dB [br]Microphone inputs[tab]2 x 6.3mm jack (mono)[br]Line inputs[tab]Line 1: L+R (6.3mm jack/RCA), Line 2: L+R (RCA)[br]Input sensitivity : line[tab]0.775Vrms[br]Auxiliary input[tab]3.5mm stereo jack[br]Input sensitivity : aux[tab]0.480Vrms[br]Input impedance[tab]20k Ohms (balanced), 10k Ohms (unbalanced)[br]Audio source[tab]USB/SD mp3 playback, FM tuner, B/T receiver[br]B/T wireless version[tab]2.3[br]Input controls[tab]Aux, Media, Line1, Line2, Mic1, Mic2, Talkover[br]Antenna connection[tab]F type (FM tuner)[br]Dynamic range[tab]92dB[br]THD +N[tab]<0.1%[br]Protection[tab]Thermal, over-current, over-voltage, short-circuit[br]Dimensions[tab]482 x 300 x 88mmLine output[tab]8 x RCA[br]Output power rms @ 4 Ohms[tab]8 x 200W[br]Output power rms @ 8 Ohms[tab]8 x 100W[br]Speaker outputs[tab]4 x 4-terminal Euroblock [br]Output controls[tab]4 x source select, Ch1 - Ch8 level[br]Weight[tab]8.96kg
