How to Operate the MCC406M Introduction The McIntosh MCC406M is a highly versatile amplifier that can be configured in many ways. This manual gives examples of some of the most common configurations. The best way to set the filter controls is through the use of a real-time spectrum analyzer and the expertise of a professional installer. This manual will guide you through the basic operation, however we suggest you refer to your Dealer for further information on the use of this unit.
How to Operate in Six or Five Channel Mode How to Operate in Six Channel Mode How to Operate in Five Channel Mode In the 6 Channel Operating Mode, channels 1 thru 4 operate as independent 50 watt amplifiers; channels 5 and 6 each provide 100 watts of power output. A typical six channel application is to use an Electronic Crossover Network ahead of the MCC406M Power Amplifier and each amplifier channel powers Loudspeaker Drivers directly. A second power amplifier is used to drive the Subwoofer.
How to Operate in Four or Three Channel Mode How to Operate in Four Channel Mode How to Operate in Three Channel Mode In the 4 Channel Operating Mode channel pairs of (1 and 2) and (3 and 4) are bridged to provide 200 watts each. Channels 5 and 6 are driven independently for 100 watts output for each channel. Refer to figures 8 and 9, along with page 11 of this Owner’s Manual. In the 3 Channel Operating Mode channel pairs of (1 and 2), (3 and 4) and (5-6) are bridged.
