Crestron AMP 2210HT

The Crestron AMP-2210HT is a two-channel commercial power amplifier whose outputs each switch, via a simple selector, between low-impedance and high-power 70V constant-voltage speaker systems. Each channel is rated for 210 watts at 70V or 4 ohms, or 120 watts at 8 ohms, and the two channels can be bridged to deliver 420 watts into a single 8 ohm load.

The HT designation marks the high-power 70V path, which is not transformer isolated on this model, an approach that trims weight and cost for installations that do not require isolation. Balanced inputs, a damping factor above 100, and a signal-to-noise ratio better than 103 dB give it clean, controlled output. The 1U chassis stands free or mounts in a 19-inch rack using the included adhesive feet and rack ears.
