The Episode® EA-AMP-8D-70A is an efficient eight-channel, Class-D amplifier that delivers a powerful 70 watts RMS per channel. Perfectly at home in multi-room applications, it features audio sensing turn-on, loop outputs, adjustable gain control and bridgeable outputs, giving installers the versatility required for today's sophisticated audio systems. Three convenient turn-on modes make it easy to integrate with simple volume controls or sophisticated control systems. Audio-sense is perfect for Sonos or Apple Airplay multi-room audio – when the last source shuts down, the amplifier will gracefully go into a power-saving standby mode. The 12V trigger inputs and outputs allow you to use a preamp or control system to turn the amp on or off, or have it "wake up" another device when the amp is activated. From single source with volume controls (Global A/B) to independent sources at each room (Direct) – or any combination in between – this amplifier has the flexibility you need. Global A/B provides two independent global sources that can be mapped to desired channel pairs. When using a stack of amplifiers, the loop outputs are a convenient way to daisy-chain the signal to downstream components. This eliminates the need for RCA splitters and gives a much cleaner (and faster) install. The EA-AMP-8D-70A offers gain adjustments for each channel pair, allowing you to independently trim output levels in each zone whether using the global or line level inputs. In volume control-based systems, these may be used to prevent harmful clipping that could cause damage to the amplifier or speakers.
