The McIntosh MC257 is a seven-channel solid-state power amplifier for systems that need substantial output across a complete surround layout. It supplies 250 watts to each of the three front channels when those channels are used alone, or 200 watts to each of seven channels with all channels operating.
Dynamic Power Manager maintains the stated output across 4- and 8-ohm loudspeakers, and the TripleView meter displays the three front-channel outputs together. Seven balanced and seven unbalanced inputs, two-zone capability, Power Guard, and Sentry Monitor support both theater and distributed-system configurations.
