Stereo Headphone Amp delivers 5\\' rms into BO ancl an internal preset sets the phones level. Two stereo headphones can be connected simultaneously. Tape, Tape Preview, Tuner and Aux inputs have sensitivity variable by internal presets from 4OmV to 1V, so that any equipment can bg exactlv matched into this amp. Hum and Noise:- better than -70c18 I u n r v e i g h t e c iI . Magnetic Pick-up inpui has sensitivity of 5mV into 47k(). Disc Hum and Noise:- better t]lan -OBdB (unlveighted).

Tape Output levels variable by internal preset betu'een 40mV and 1V. Outputs for two separate pairs of loudspeakers. Outputs are short-circuit protected and fused. Mains facility outlets: one srvitched, two unswitched and all fused. Power amps. have individual fuses which also protect the pou'er supply. Maximum load: Not less than 4O per channei. Fast music transients are not limited by the output protection cirCuitry up to BOWpeaks into 8f). Peak overload detector LED's to indicate if input gain presets have been set too sensitive. Mono buttons switch one input or both inputs to both main channels. Tone cancel button to cut out all filters and tone controls for a perfectly flat response.
