Our take on the McIntosh MC7108 8-Channel Configurable Power Amplifier

The McIntosh MC7108 is a multi-channel power amplifier that can be set up for 4, 5, 6, 7 or 8 channels. In its standard form it gives eight 40-watt channels; bridging pairs turns them into 100-watt channels, so you trade channel count for power. That flexibility suits home theater and multi-zone stereo systems that need many modest channels or a few stronger ones. Against fixed-channel multichannel amps, its configurable bridging is the main draw, though 40 watts per channel is modest and bridged outputs are rated only for 4-ohm loads.

About the McIntosh MC7108 8-Channel Configurable Power Amplifier

The McIntosh MC7108 is a multi-channel solid-state power amplifier that can be set up for 4, 5, 6, 7 or 8-channel operation. In its standard configuration it provides eight channels at 40 watts each. Pairs of channels can be bridged to make 100-watt outputs, so channel count can be traded for more power.

Connections are RCA inputs and outputs, screw terminals for the speakers, and 12V triggers. The power cord is captive. Power Guard prevents clipping, and total harmonic distortion stays at or below 2% with up to 14dB of overdrive at 1000Hz.

Channels
Configurable for 4, 5, 6, 7 or 8 channels
8-channel mode
8 x 40W
7-channel mode
6 x 40W + 1 x 100W bridged

Questions and answers

How does bridging change the channel count?
Each bridged 100-watt channel uses a pair of amplifier channels. So 8 channels of 40 watts become 4 channels of 100 watts, with 5, 6 and 7-channel mixes in between.
What speaker impedance do the bridged outputs need?
Bridged operation is rated for 4-ohm loudspeaker loads. Check your speakers' impedance before bridging.
Is 40 watts per channel enough for home theater?
It depends on your speakers and room. Eight 40-watt channels suit efficient surround speakers; bridge pairs for 100 watts on the front channels if you need more headroom.
Can it run a stereo system and a theater setup?
Yes. You can assign channels to different zones or bridge pairs for a stronger stereo pair, which is the point of the configurable layout.
What should I check on a used unit?
Ask about channel-by-channel testing, the volume trimmers and the lamps, since these are common service points on older units.
Where is the McIntosh MC7108 8-Channel Configurable Power Amplifier cheapest?
