 MS-A1004 is a compact, four-

channel amplifier that gives you up to 400 watts of raw power to use any way you see fit. It connects to any line-level 
or speaker-level output, and features onboard displays for easy, foolproof installation and configuration. A digital input 
mixer lets you map your inputs to any speaker outputs, and sophisticated network circuitry puts you in precise control 
of the crossover points and slopes of each channel pair. With great power comes great possibilities – not to mention 
great sound – and the MS-A1004 delivers on all counts.
