The latest advances in sound system technology such

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.
