Connector and Cable Information

Introduction

Now you can take advantage of traditional McIntosh

standards of excellence in the MC312 Power Amplifi-

er. The 300 watts power per channel with high current

output will drive any pair of high quality Loudspeak-

ers. The MC312 reproduction is sonically transparent

and absolutely accurate. The McIntosh Sound is “The

Sound of the Music Itself.”

Performance Features

• Power Output

The MC312 is a Power Amplifier with a capability

of 300 watts per channel into 2, 4 or 8 ohm speakers

with less than 0.005% distortion. The Power Amplifier

Circuitry uses ThermalTrak

1

Output Transistors for

lower distortion and cool operation.

• Patented Autoformer

McIntosh designed and manufactured Output Auto-

formers provide an ideal match between the amplifier

output stages and speaker loads of 2, 4 and 8 ohms.

The Autoformers also provide perfect DC protection

for your valuable loudspeakers.

• Balanced and Unbalanced Inputs

Balanced connections guard against induced noise and

allow long cable runs without compromising sound

quality.

• Power Guard

The patented McIntosh Power Guard circuit prevents

the amplifier from being over driven into clipping,

with its harsh distorted sound that can also damage

your valuable loudspeakers.

• Sentry Monitor and Thermal Protection

McIntosh Sentry Monitor power output stage protec-

tion circuits ensure the MC312 will have a long and

trouble free operating life. Built-in Thermal Protection

Circuits guard against overheating.

• Special Power Supply

A very large Power Transformer and Large Capaci-

tors ensure stable noise free operation even though the

power line varies.

• Illuminated Power Meters

The Illuminated Power Output Watt Meters on the

MC312 are peak responding, and indicate the true

power output of the amplifier. The Peak Watt Hold

Mode allows the meter to temporarily stay at the high-

est power output and then slowly decay. The Front

Panel Meter Illumination may be switched Off at any

time.

• McIntosh Custom Binding Posts

McIntosh patent pending gold plated output terminals

deliver high current output. They accept large diam-

eter wire and spade lugs. Banana plugs may also be

used only in the United States and Canada.

• Glass Front Panel and Super Mirror Chassis

Finish

The famous McIntosh Illuminated Glass Front Panel

uses long life Light Emitting Diodes (LEDs) and

the Stainless Steel Chassis with Super Mirror Fin-

ish ensures the pristine beauty of the MC312 will be

retained for many years.

XLR Connectors

Below is the Pin configuration for the XLR Balanced

Input, Input/Output Connectors on the MC312. Refer

to the diagram for connection:

PIN 1: Shield/Ground

PIN 2: + Input/Output

PIN 3: - Input/Output

Power Control Connector

The MC312 Power Control Input receives an On/Off

signal from +5 to +12 volts. The Power Control Output

will in turn provide a +12 volt

Output Signal with a total cur-

rent up to 50mA. An additional

connection is for controlling

the illumination of the MC312

Power Output Meters. The 1/8

inch stereo mini phone plug connects to a McIntosh

Preamplifier or A/V Control Center Power Control

Output.

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

(7.6m m).
