7. The MAC7200 Remote Control is capable of oper-ating other components. For additional informa-
tion go to www.mcintoshlabs.com.
8. RF Multipath interferance can occur when the MAC7200 receives two or more signals from the
Tuned in FM Broadcast Station. The first signal
received is the direct signal from the station and
additional signals received are delayed because
they have ref lected off of a building or terrain
(hill/mountain). This delay results in an increase
in distortion and a reduction in Stereo Separa-
tion. To reduce or eliminate Multipath, reorient
the direction of the FM Antenna for minimum
indication of Multipath even if the Signal Strength
indicates less signal. Refer to pages 33 and 34.
9. The IR Input, with a 1/8 inch mini phone jack, is configured for non-McIntosh IR sensors such as
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
MAC7200. The signal from a connected External
IR Sensor will have priority over the signal from
the Front Panel IR Sensor.
10. 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 regula-
tions concerning battery disposal.

owners manual(s) for any component(s) connected
to the MAC7200.
2. Apply AC Power to the MAC7200 and other McIn- tosh Component(s) only after all the system compo-
nents are connected together. Failure to do so may
cause a malfunction of system operations as the
Microprocessors Circuitry inside the components
is active when AC Power is applied.
3. The MAC7200 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 MAC7200 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 operat-
ing temperature, AC Power is removed from the
MAC7200. 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
13 and 14.
Note: The impedance of a Loudspeaker actually var ies 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 Manufac
turer for additional information about the actual
impedance of the Loudspeaker before connecting
it to the McIntosh MAC7200.

RS232-C Data Port Cable The RS232 Data Cable is a 3.5mm stereo mini phone
plug to a subminiature DB 9 connector: Output Terminal Connector When cables with spade lugs are used
for Loudspeaker Connection, the spade
lugs need an opening of at least 3/10 inch
(7.6mm). McIntosh Plug-In Jumper Connector The MAC7200 utilizes two phono style Plug-In Jump-
ers to connect the Preamplifier Output to the Power
Amplifier Input. Note: The Jumper Connector is available from the McIntosh Parts Department:
McIntosh Jumper Connector Part
No. 117781 FM Dipole Antenna
The MAC7200 FM Tuner Circuitry requires the con-
nection of an external Antenna for FM reception. A
FM Dipole Antenna is available from the McIntosh
Parts Department:
FM Dipole Antenna Part
No. 173033
XLR Connectors Below is the Pin configuration for the XLR Balanced Input
Connectors on the MAC7200. Refer to the diagram for con-
nection:

PIN 2: + Output
PIN 3: - Output Power Control and Trigger Connectors The Power Control Trigger Output
Jacks send and Passthru Input Jack
receives Power On /Off Signals
(+12 volt/0 volt) when connected
to other McIntosh Components.
An additional connection is for
controlling the illumination of the
Power Output Meters on McIntosh
Power Amplifiers. A 3.5mm stereo mini phone plug is
used for connection to the Power Control, Trigger and
Passthru Outputs. Data Port Connectors The Data Out Ports send Remote
Control Signals to Source Compo-
nents. A 3.5mm stereo mini phone
plug is used for connection. IR IN Port Connectors The IR IN Port also uses a 3.5mm
stereo mini phone plug and allows
the connection of other brand IR
Receivers to the MAC7200. Connector and Cable Information

McIntosh RAA2 AM Antenna
The AM Tuner Circuitry requires the connection
of the external McIntosh RAA2 Antenna for AM
reception. The RAA2 Antenna is supplied with the
MAC7200 Receiver. The AM Antenna is also avail-
able from the McIntosh Parts Department:

Caution: Do not connect the AC Power Cord to the MAC7200 Rear Panel until after the Loud-
speaker Connections are made. Failure to
observe this could result in Electric Shock. The connection instructions below, together with
the MAC7200 Connection Diagram located on the
separate folded sheet Mc2B, is an example of a typi-
cal 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 4.
The McIntosh MAC7200 Power Amplifier Circuit-
ry is designed for Loudspeakers with an impedance of
2 ohms, 4 ohms or 8 ohms. Connect a single Loud-
speaker only to the Right and Left Output Terminals. When connecting Loudspeakers to the MAC7200
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: Loudspeaker Cable Distance vs Wire Gauge Guide Loudspeaker Impedance 25 feet

1. Prepare the Loudspeaker Hookup Cable for attach- ment to the MAC7200 Power Amplifier:Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures F, G & H. If the cable
is stranded, carefully twist the strands together
as tightly as possible.
Notes: 1. If desired, the twisted ends can be tinned with solder to keep the strands together.
2. The prepared bare wire cable ends may be inserted into spade lug connectors.
3. Banana plugs are for use in the United States and Canada only.
