Audica Professional Micro Series 4-Channel Power Amplifier MICROplus

The Audica Professional MICROplus is an ultra-compact 4-channel power amplifier with the same size and style of head-unit mounting as the MICROzone pre/amp/controller, which it is designed to partner. It delivers 4 x 80W into 4 Ohm per channel, 2 x 80W into 4 Ohm plus 1 x 160W bridged into 8 Ohm or 2 x 160W into 8 Ohm with twin channels bridged. Features include 4-channel limiting and protection and individual channel bar indicators showing output level, clip and fault. The unit has rear-mount level control, phono in/out and screw terminal loudspeaker outputs for each channel. Being a straight gain amplifier, the MICROplus is designed to be used in conjunction with the MICROzone, which provides pre-amp functions and the equalization for the MICROseries loudspeakers. Programme power output: 80W into 4 Ohms, 40W into 8 Ohms Bridge Mode (per pair of channels): 160W into 8 Ohms Sine wave r.m.s. power output: 55W into 4 Ohms, 28W into 8 Ohms (restricted by limiter operation) Peak power output: 160W into 4 Ohms, 80W into 8 Ohms Gain: -infinity to 28.2dB (adjustable on rear panel) Frequency Response: <10Hz to 35kHz (-3dB), less than 1dB down @ 20kHz Signal to Noise ratio: 86dB (22Hz to 22kHz), 90dB (A-weighted) THD: <0.03% (at 1kHz and 25W), <1% (20Hz-20kHz) all output levels Input level for 55W output (limiter operation begins): 610mV r.m.s. at maximum gain setting Input impedance: 10k ohms
