[. . . ] Warning: To reduce risk of fire or electrical shock, do not expose this equipment to rain or moisture. This unit is capable of producing high sound pressure levels. Continued exposure to high sound pressure levels can cause permanent hearing impairment or loss. User caution is advised and ear protection is recommended when playing at high volumes. [. . . ] The MCC301M Line Level OUTPUT is wired as a "Y" connection with the INPUT to pass the input signals on to additional amplifiers (keep cable lengths as short as possible). The McIntosh MX406 Control Center is capable of driving several additional power amplifiers with no degradation of the signal. The MCC301M can accept speaker level inputs at its Input Jacks. Refer to the diagram for (-) NEGATIVE SPEAKER OUTPUT connection. Customer Service If it is determined that your McIntosh product is in need of repair, you can return it to your dealer.

(+) POSITIVE SPEAKER OUTPUT 3 Introduction Now you can take advantage of traditional McIntosh standards of excellence in the MCC301M Power Amplifier. A 300 watt high current output will drive any high quality loudspeaker to its ultimate performance. The MCC301M reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is "The Sound of the Music Itself. " · Thermal Protection with Multi-Speed Cooling Fans Built-in thermal protection circuits guard against overheating which could shorten the normal long life expectancy of your McIntosh Power Amplifier. Cooling fan speed is controlled by temperature sensors attached to the interior of the extruded aluminum cooling tunnel. The cooling fans are controlled by temperature sensors, attached to the interior of the tunnel. If the program material contains sustained loud passages demanding high power, the fans 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 LED will light. The fans 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 housings and heat tunnel vents can allow internal components to be damaged by exposure to water, chemicals or any form of road dust or debris. Removing the Glass Panel To access the MCC301M Controls, remove the glass panel by removing the four hex bolts with the supplied 3/32" hex key. 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. [. . . ] The equalizer is not intended to act as a tone control. The one-band equalizer is best utilized as a notch filter to reduce a peak (as located by real-time analysis with an RTA) in your system's frequency response. If you are attempting to equalize a system without RTA data, play 11 How to Replace the Fuses How to Replace the Fuses If the MCC301M produces no sound, there is no Illumination of the Meter on the Top Glass Panel, and the power connections seem secure, one or more of the Amplifier's Fuse(s) may have failed. Under normal operating conditions your amplifier's fuses should not fail. [. . . ]
