Cooling fan speed is controlled by temperature sensors attached to the interior of the extruded aluminum cooling tunnel. The fan is normally off. When needed, the fan will automatically switch on, and speed is increased as needed for additional cooling. • Fully Discrete Design The MCC204 has a fully complimentary double balanced amplifier design and is identical to that found in McIntosh’s leading home amplifiers. • Balanced Inputs with Pass Through The Balanced Inputs cancel out interference noise that is produced by other sources in the vehicle and can be directly connected to the bridged speaker output of any head unit. The MCC204 provides four line level outputs, for the convenience of connecting multi-amplifier systems. • Remote Subwoofer Control and Line Output The subwoofer level can be controlled via an external rotary control, which can be remotely mounted in the vehicle. A line level summed output is provided to drive an external subwoofer power amplifier. The inputs to both channels are summed for this output. • Gold Plated Terminals McIntosh provides gold plated input and output terminals on the amplifiers for superior corrosion resistance. It is a very important feature in the automotive environment. Speaker wires to 10 AWG and DC input wires to 4 AWG can be accommodated. 4 Dimensions Dimensions The following dimensions can assist in determining the best location for your MCC204. There is additional information on the next page pertaining to installing the MCC204 into your vehicle.

Amplifier Ventilation Always provide adequate ventilation for the MCC204. The amplifier requires an adequate airflow into the cooling fan, which is located on the left side of the amplifier. The warm air exits the amplifier through vents on the heatsinks. See figure I. Be sure to provide at least 1-1/2 inches clearance in front of the cooling fan and 1 inch clearance at the sides of the heatsinks. The cooling fan is controlled by temperature sensors, attached to the interior of the tunnel. The fan is normally off. If the program material contains sustained loud passages demanding high power, the fan will turn-on to increase cooling. If cooling is still not sufficient, additional heating will shut down the amplifier’s internal power supply completely and the Power Guard LEDs will light. The fan will continue to run and once normal temperatures are restored, operation will resume. The amplifier can be mounted vertically or horizontally and may be located under a seat if adequate clearance is available. The preferred installation method is to mount the amplifier directly to the vehicle frame using the hardware supplied with the amplifier. It is not recommended that the amplifier be mounted under the hood or in a location where it will be directly exposed to the elements. The openings in the fan housing and heat tunnel vents can allow internal components to be damaged by exposure to water, chemicals or any form of road dust or debris. Figure 1 Cool Air Figure 2 Removing the Glass Panel To access the MCC204 Controls, remove the glass panel by removing the four hex bolts with the supplied 3/32” hex key. See figure 2. Attach the supplied suction cup to the top center of the glass panel and carefully raise it high enough to put your hand under. Temporarily place the removed glass panel in a safe place, remove the suction cup and save it for future use. Removing the End Caps To access the MCC204 Connecting Terminal Blocks, remove the Glass Panel first (the above step) and then remove the Phillips Screws holding the End Caps on both sides of the amplifier and lift the end caps off. See figure 3.
