General Information, Connector and Cable Information
General Information
1.For additional connection information, refer to the owner’s manual(s) for any component(s) connected to the MA7200.
2.Apply AC Power to the MA7200 and other McIntosh Component(s) only after all the system components are connected together. Failure to do so may cause a malfunction of system operations as the Microprocessor’s Circuitry inside the components
is active when AC Power is applied.
3.The MA7200 includes an Auto Off Power Save Feature and the default setting is enabled. For
additional information including how to disable it, refer to page 22.
4.When Power Amplifier Protection Circuitry of the MA7200 has activated, the Front Panel Power Guard LEDs are illuminated continuously and the sound will be muted.
5.When the Power Transformer has overheated due to improper ventilation and/or high ambient operating temperature, AC Power is removed from the MA7200. Normal operation will resume when the operating temperature is in a safe range again.
6.For the best performance and safety, it is important to always match the impedance of the Loudspeaker to the Power Amplifier connections. Refer to pages 10 thru 12.
Note: The impedance of a Loudspeaker actually varies as the Loudspeaker reproduces different frequencies. As a result, the nominal impedance rating of the Loudspeaker (usually measured at a midrange frequency) might not always agree with the impedance of the Loudspeaker at low frequencies where the greatest amount of power is required. Contact the Loudspeaker Manufacturer for additional information about the actual impedance of the Loudspeaker before connecting
it to the McIntosh MA7200.
7.The MA7200 Remote Control is capable of operating other components. For additional information go to www.mcintoshlabs.com.
8.The IR Input, with a 1/8 inch mini phone jack, is configured for non-McIntosh IR sensors such as a Xantech Model DL85K Kit. Use a Connection Block such as a Xantech Model ZC21 when two or more IR sensors need to be connected to the MA7200. The signal from a connected External IR Sensor will have priority over the signal from the Front Panel IR Sensor.
9.When discarding the unit, comply with local rules
or regulations. Batteries should never be thrown away or incinerated but disposed of in accordance with the local regulations concerning battery disposal.
10.For additional information on the
MA7200 and other McIntosh Products please visit the McIntosh Web Site at www.mcintoshlabs.com.

Connecting for Bi-Amplification
Connecting for Bi-Amplification
The MA7200 Power Amplifier, together with an additional separate Power Amplifier, may be used to Bi-Amplify a Loudspeaker System. In the illustration on this page, the Power Amplifier of the MA7200 is connected to the Midrange/High Frequency Section of the Loudspeaker. The additional separate Power Amplifier is connected to the Low Frequency Section of the Loudspeaker System.
Warning: The Loudspeaker System used for Bi-Amplification must have the jumpers removed from between the MID/HIGH and LOW Frequency Sections of the Loudspeaker System. Failure to remove them could result in damage to the MA7200 and/or the separate Power Amplifier.
MA7200 Connections:
1.Remove the “McIntosh Jumpers” from between the OUTPUT 1 Jacks and the PWR AMP In Jacks located on the Rear Panel of the MA7200.
Note: Place the “McIntosh Jumper” in a safe place for possible future use.
2.Using a pair of shielded RCA Type Audio “Y” Adapters connect the OUTPUT 1 Jacks to the PWR AMP In Jacks, for both Left and Right Channels.
3.Connect the remaining unconnected part of the “Y” Adapters to the separate Power Amplifier.
4.Referring to the Loudspeaker Connection Instructions on page 11, and in the Owner’s Manual supplied with the Power Amplifier and Loudspeaker, connect the MA7200 Output Terminals to the Loudspeaker MID/HIGH Input Terminals.
Note: The Loudspeaker Connection illustrations on this page are for the Left Channel. Connect the Right Channel Loudspeaker in the same manner.

How to Connect Loudspeakers
Caution: Do not connect the AC Power Cord to the MA7200 Rear Panel until after the Loudspeaker Connections are made. Failure to observe this could result in Electric Shock.
The connection instructions below, together with the MA7200 Connection Diagram located on the separate folded sheet “Mc2B”, is an example of a typical audio system. Your system may vary from this, however the actual components would be connected in a similar manner. For additional information refer to “Connector and Cable Information” on page 3.
The McIntosh MA7200 Power Amplifier Circuitry is designed for Loudspeakers with an impedance of 2 ohms, 4 ohms or 8 ohms. Connect a single Loudspeaker only to the Right and Left Output Terminals.
When connecting Loudspeakers to the MA7200 it is very important to use cables of adequate size, so
there is little to no power loss in the cables. The size is specified in Gauge Numbers or AWG (American Wire Gauge). The smaller the Gauge number, the larger the wire size:

4. Referring to figure K, connect the Loudspeaker hookup cables with
banana plugs into the hole at the top of the terminal to
the MA7200 Negative Output Terminal and Positive Output Terminal indentified as 2Ω
(ohms), 4Ω (ohms) or 8Ω (ohms) connection
to match the impedance of the Loudspeaker, being careful to observe the correct polarities.
Note: The illustration located on the separate folded sheet “Mc2B” is for connection to an
8Ω (ohms) Loudspeaker.
If the Loudspeaker’s impedance is in-between the available connections, use the nearest lower
impedance connection. Refer to “General Information” Note 6 on page 3 for additional information.
WARNING: Loudspeaker terminals are hazardous live and present a risk of electric shock. For additional instruction on making Loudspeaker Connections contact your McIntosh Dealer or McIntosh Technical Support.
