4 Important Information 1. An optional McIntosh External Subwoofer Rotary Control, Model Number R1163, is available from your McIntosh Dealer. 2. Do not connect the Amplifier Speaker Negative Terminal Connection directly to the Vehicle Chassis. Failure to observe this could result in damage to your Amplifier. 3. For additional connection information, refer to the owner s manual(s) for any component(s) connected to the MCC406M Amplifier. 4. There is a built-in turn on delay which will mute the speaker outputs for approximately two seconds when the amplifier is turned on. 5. It is very important that loudspeaker cables of adequate size be used in your music system, to ensure that there will be no power loss or heating. If your loudspeaker cables are 25 feet (7.62m) or less, use at least 16 Gauge wire size or larger. 6. It is advisable to place an in- line fuse as close as possible to the battery. 7. The MCC406M can accept speaker level inputs at its Input Jacks. Refer to the diagram for connection. Performance Features Introduction - -- - - Power Output The MCC406M consists of six separate power amplifier channels, with four channels each capable of 50 watts and two channels each capable of 100 watts with less than 0.005% distortion. - -- - - Six Bridgeable Channels The MCC406M includes four 50 watt amplifier channels. Each pair of channels can be set in bridged configuration for 200 watts output into a 4 ohm Loudspeaker. The two 100 watt channels may also be bridged for 400 watts out- put into a 4 ohm Loudspeaker. Now you can take advantage of traditional McIntosh stan- dards of excellence in the MCC406M Power Amplifier. The MCC406M has 400 watts of combined power output with high current capability from six, five, four or three channels and will drive any high quality Loudspeaker Sys- tem to its ultimate performance. The MCC406M reproduc- tion is sonically transparent and absolutely accurate. The McIntosh Sound is The Sound of the Music Itself. (-) NEGATIVE SPEAKER OUTPUT (+) POSITIVE SPEAKER OUTPUT - -- - - High Current Output A peak output current of 20 amperes ensures that the MCC406M will successfully drive high quality Loud- speakers, such as McIntosh, for a truly exciting sound ex- perience. - -- - - Variable Crossover Filters The 12dB per octave high pass filters have variable corner frequencies from 5Hz to 5,000Hz and 12dB per octave low pass filters with variable corner frequencies from 50Hz to 5,000Hz. - -- - - Illuminated Watt Meters The MCC406M has Output Watt Meters that display the combined output in watts for all six channels. The meters respond 95% full scale to a single cycle tone burst at 2kHz. It is almost ten times faster than a professional VU meter. - -- - - Power Guard and Sentry Monitor All channels include the patented McIntosh Power Guard circuit that prevents the amplifier from being overdriven into clipping with its harsh distorted sound that can also damage your valuable Loudspeakers. McIntosh Sentry Monitor power output stage protection circuits are present on all channels to ensure the MCC406M will have a long and trouble free operating life. - -- - - Speaker Protection If for any reason, a DC (Direct Current) voltage appears at the speaker output terminals, a built-in circuit turns off the amplifier power supplies to prevent damage to your valu- able Loudspeakers. - -- - - Thermal Protection with Multi-Speed Cooling Fans Built-in thermal protection circuits guard against overheat- ing which could shorten the normal long life expectancy of your McIntosh Power Amplifier. Cooling fan speed is con- trolled by temperature sensors attached to the interior of the extruded aluminum cooling tunnel. The fans normally run at a quiet low speed, when needed the fans will auto- matically switch to a higher speed for increased cooling. - -- - - Subwoofer Output Remote Control An optional Subwoofer Remote Control Accessory may be connected to the MCC406M and allows varying the Subwooofer output level.
