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 connec-
tion to the Power Control and the Passthru jacks.

Data Port Connectors

The Data Out Ports send Remote Control Signals to
Source Components. A 3.5mm stereo
mini phone plug is used for connec-
tion.

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
MA5200.

RS232-C Data Port Cable

The RS232 Data Cable is a 3.5mm stereo mini phone
plug to a subminiature DB 9 connector:

McIntosh Plug-In Jumper Connector

The MA5200 utilizes a phono style Plug-In Jumper to
connect the Preamplifier Output to the
Power Amplifier Input, one Jumper for
each channel.

Note: The Jumper Connector is available from the McIn-

tosh Parts Department:

McIntosh Jumper Connector Part No. 117781

XLR Connectors

Below is the Pin configuration for the XLR Balanced
Input Connectors on the MA5200. Refer to the dia-
gram for connection:

PIN 1: Shield/Ground

PIN 2: + Output

PIN 3: - Output

Power Control Connectors

The Power Control Output Jack sends and Passthru
Input Jack receives Power On/Off Signals (+12 volt/0

2. Apply AC Power to the MA5200 and other McIn-

nents 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.

The MA5200 includes an Auto Off Power Save

Feature and the default setting is enabled.

For

additional information including how to disable it,
refer to page 21.

is compatible with high output Moving Coil Phono
Cartridges such as the Sumiko Blue Point No.2.

5. When Power Amplifier Protection Circuitry of

the MA5200 has activated, the Front Panel Power
Guard LEDs are illuminated continuously and the
sound will be muted.

6. When the Power Transformer has overheated due

to improper ventilation and/or high ambient operat-
ing temperature, AC Power is removed from the
MA5200. Normal operation will resume when the
operating temperature is in a safe range again.

7. 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
12 and 13.

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 MA5200.

8. The MA5200 Remote Control is capable of operat-

ing other components. For additional information
go to www.mcintoshlabs.com.

9. The IR Input, with a 1/8 inch mini phone jack, is

configured for non-McIntosh IR sensors such as
a Xantech Model HL85BK Kit. Use a Connection
Block such as a Xantech Model ZC21 when two
or more IR sensors need to be connected to the
MA5200. 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 regulations
concerning battery disposal.
