The DX400 is a robust, one rack space amplifier suitable for the smaller PA system and studio monitoring. 

The steel enclosure houses the reliable bi-polar amplifiers that are cooled by twin variable speed fans. Signal inputs are via xlr, jack and RCA phono connectors whilst the outputs have binding posts and industry standard 4 pole connectors. Signal status employs SIG and CLIP leds and volume is controlled by individual level controls. Its small size and low weight make it a great full range amplifier that will sound good on live or monitoring duties.
