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.
