This series dubbed the “Apple” range have been completely redesigned by Biema to offer vastly improved cooling, efficiency and circuit protection. This range is designed to function as a high power stereo (non-bridgeable) amplifier for use in foreground sound reinforcement ie: pubs, clubs, cinemas and multi-function venues. The variable speed cooling fan and ‘T’ shaped heatsink tunnel ensure the amplifier performs well even in demanding conditions. The protection circuitry employed ensures the integrity of the amplifier during overload condition, output terminal short circuit and output clipping.
