The Russound MCA-66 is a centralized multiroom audio controller and amplifier that lets six rooms each pick from six shared sources. All six zones are amplified on board at 20 watts per channel into 8 ohms, so a single rack unit can drive in-ceiling or in-wall speakers throughout a home or small business without separate power amplifiers.
Source connections include six stereo RCA line inputs plus three coaxial and one optical digital input (six sources maximum in total). Zones 1 and 2 also provide line-level outputs that can be set fixed or variable, handy for feeding a larger amplifier or a powered subwoofer. For control, the MCA-66 offers an Ethernet port, RS-232, RNET in/out links, six routed IR outputs, home-theater and paging triggers, and six keypad ports. It works with the Russound app, IPK-1 keypads and XTS7 touchscreens, and supports Alexa voice control. When six zones are not enough, up to six MCA-66 units can be linked to reach 36 zones.
