SX Series

Introduction
Specification

The SX range are rugged yet light weight amplifiers capable of producing quality sound at all power levels. There are three models in the range, all occupy only 2 rack spaces and are forced cooled via a thermally controlled fan.

There are 3 modes of operation available stereo, mono or bridged and the input sensitivity can be trimmed by +-3dB for system matching. The inputs use combined XLR and jack socket combination connectors with a separate link socket to feed additional amplifiers. The outputs use industry standard four pole connectors with binding posts giving total flexibility. Front panel status LEDs provide visual indication of signal levels (SIG, -20, -10 and PEAK), BRIDGED mode and POWER.

The two large level controls aid precise volume setting and the durable black finished steel cabinet can handle life on the road. With the highest powered model (SX4500) weighing only 12.5kg the SX range price/performance/ratio is your only choice!
