The latest advances in sound system technology such as multi-channel immersive sound surrounds and tri-amplification require more amplifier channels than ever before. That's why we designed our newest DCA amplifiers to give you four channels of power in a compact package that doesn't eat up precious rack space. And, compared to the cost of two stereo amplifiers, you'll find they leave more room in your budget as well. In addition to their superior performance we've packed these amps with useful features designed specifically for the cinema market.
