It also can be custom installed in side of the Integrated Amplifier, so that airflow is not oba piece of furniture or cabinet of your choice. The four feet structed. Allow 20 inches (50.8cm) depth behind the front may be removed from the bottom of the MA7000 when it panel.
Rear Panel Connections Connect the MA7000 power cord to a live AC outlet.
Connecting Components The MA7000 has the ability to automatically switch power On/Off to McIntosh Source Components via the Power Control connections. The Data Port Connections allow for the remote operation of basic functions using the MA7000 Remote Control. With an external sensor connected to the MA7000, remote control operation of the system is possible from another room and/or when the MA7000 is located in a cabinet with the doors closed.
How to Connect Connecting Loudspeakers Caution: The supplied AC Power Cord should not be connected to the Rear Panel of the MA7000 Amplifier until after the Loudspeaker Connections have been made. Failure to observe this could result in Electric Shock. For additional instruction on making Loudspeaker Connections contact your McIntosh Dealer or McIntosh Technical Support.

How to use the Remote Control How to use the Remote Control The supplied Remote Control is capable of directly controlling the functions of contemporary McIntosh Source Components connected to the MA7000 via the Data Ports. Input Source Selection Press the appropriate Source Push-button to select the desired program source. Mute Press the MUTE Push-button to mute the audio in all outputs except the REC OUTPUT. The MUTE LED above the push-button will flash on and off to indicate that Mute is active.
Front Panel Displays, Controls, Push-buttons and Jack LED indicates when the Left Channel Amplifier POWER GUARD circuit activates Meter indicates the Right Channel Output of the amplifier Equalizer Controls provide 12dB of boost or cut at the center frequencies indicated above each control The LEDs above the push-buttons indicate the current source selected.
How to Operate the MA7000 How to Operate the MA7000 Power On The Red LED above the STANDBY/ON Push-button lights to indicate the MA7000 is in Standby mode. To Switch ON the MA7000, press the STANDBY/ON Push-button on the Front Panel or the Power Push-button on the Remote Control. The MUTE LED will light for approximately two seconds after turn on. Refer to page 12 and figure 7. Note: For an explanation of the Remote Control Push-button functions, refer to pages 10 and 11.
How to Operate the MA7000, con’t How to Operate the MA7000, con’t Using a Separate Power Amplifier There are two different ways to use a separate power amplifier with a MA7000. The first way is to use the separate amplifier instead of the MA7000 built-in Power Amplifier. Connect the Loudspeakers to the separate power amplifier and remove the McIntosh Jumpers that are located between the OUTPUTS 1 Jacks and the POWER AMP INput Jacks. Refer to figure 8.
Technical Description Technical Description McIntosh Laboratory, the company who introduced the world’s first amplifier that could be called “High Fidelity”, has done it again. The McIntosh engineering staff has created a power amplifier without compromise, using the most advanced McIntosh circuit design concepts.
sealed with tiny leads protruding from either end. Refer to figure 10. These leads extend into the tube and overlap one another with a separation of a few thousandths of an inch. The leads are made from a ferrous material that Figure 10 is influenced by a magnetic field. They are first plated with gold as a base material, then with rhodium and finally ruthenium. Ruthenium is the best contact material known. The glass assembly is then placed in the center of a multilayer coil of copper wire.
Technical Description, con’t Autoformers All solid state power amplifier output circuits work best into what is called an optimum load. This optimum load may vary considerably from what a loudspeaker requires. In the case of more than one loudspeaker connected in parallel, the load to the power amplifier may drop to two ohms or even less.

Packing Instructions Packing Instructions In the event it is necessary to repack the equipment for shipment, the equipment must be packed exactly as shown below. It is very important that the four plastic feet are attached to the bottom of the equipment. Four 1/4 - 20x2-1/4 inch screws and washers must be used to fasten the unit securely to the bottom pad and wood skid. This will ensure the proper equipment location on the bottom pad. Failure to do this will result in shipping damage.
