on McIntosh Power Amplifiers. A 3.5mm stereo mini 
phone plug is used for connection to the Power Con-
trol, 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 Receiv-
ers to the MA5300.
RS232-C Data Port Cable
The RS232 Data Cable is a 3.5mm stereo mini phone 
plug to a sub miniature 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 MA5300 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
XLR Connectors
Below is the Pin configuration for the XLR Balanced 
Input Connectors on the MA5300. Refer to the dia-
gram for connection:
 
PIN 1: Shield/Ground
 
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 connec-
tion is for controlling the illumina-
tion of the Power Output Meters 
1. For additional connection information, refer to the 
owner’s manual(s) for any component(s) connected 
to the MA5300.
2. Apply AC Power to the MA5300 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 
Microprocessor’s Circuitry inside the components 
is active when AC Power is applied.
3. The MA5300 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.
4. When Power Amplifier Protection Circuitry of 
the MA5300 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 
MA5300. 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 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 MA5300.
7. The MA5300 Remote Control is capable of operat-
ing 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 
MA5300. 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 regula-
tions concerning battery disposal.
