MI347 Power Amplifier

The McIntosh MI347 is a seven-channel digital power amplifier designed around a complete surround system. Its three front channels provide 250 watts into 8 ohms or 300 watts into 4 ohms, while the four surround channels provide 125 watts into 8 ohms or 200 watts into 4 ohms.

Seven balanced and seven unbalanced inputs support connection to a theater processor, and the 3U rack-mountable chassis keeps all channels together. On/off signal sensing, Power Control, Power Guard, and Sentry Monitor support automated, supervised operation in a custom installation.
