General Notes
Caution: The MC602 Amplifier weight is 155 pounds
(70.31 kilograms). It requires two or more persons
to safely handle when moving the amplifier.
1. The following Connecting Cable is available from the
McIntosh Parts Department:
Power Control Cable Part No. 170-202
Six foot, 2 conductor shielded, with two 1/8 inch stereo
mini phone plugs.
2. For additional connection information, refer to the owners
manual(s) for any component(s) connected to the MC602.
3. The MC602 mutes the speaker outputs for approximately two
seconds when first turned on.
4. It is very important that loudspeaker cables of adequate size
be used, so that there will be no power loss. The size is
specified in Gauge Numbers or AWG, (American Wire Gauge).
The smaller the Gauge number, the larger the wire size:
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 14 Gauge.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 12 Gauge.
5. Pin configuration for the XLR Balanced Input connectors on
the MC602: PIN 1: Shield or ground
PIN 2: + input
PIN 3: - input
6. In the event that the MC602 over heats, due to improper
ventilation and/or high ambient temperature, the protection
circuits will activate. The Front Panel Power Guard LEDs
will continuously indicate ON and the audio will be muted.
When the MC602 has returned to a safe operating
temperature, normal operation will resume.
7. The MC602 incorporates the very latest in Fully Double
Balanced Circuitry. As a result, the Loudspeaker Negative
Connections are above chassis ground and are not common
between channels. Do not combine any connections together
or ground them.
Now you can take advantage of traditional McIntosh standards of excellence in the MC602 Power Amplifier. Two
600 watt high current output channels will drive any high
quality loudspeaker system to its ultimate performance.
The MC602 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is The Sound of the
Music Itself.
Performance Features
· Power Output
The MC602 consists of two separate power amplifier channels, each capable of 600 watts into 2, 4 or 8 ohm speakers
with less than 0.005% distortion.
· Full Balanced Circuity
The MC602 is fully balanced from inputs to outputs. Each
channel consists of two matched power amplifiers operating in push-pull with their outputs combined in a McIntosh
Autoformer. The double balanced configuration cancels
virtually all distortion.
· Power Guard
Both channels include the patented McIntosh Power Guard
circuit that prevents the amplifier from being overdriven
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 protection
circuits ensure the MC602 will have a long and trouble free
operating life. Built-in Thermal Protection Circuits guard
against overheating.
· Patented Autoformers
McIntosh designed and manufactured Output Autoformers
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.
· Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MC602
are peak responding, and indicate the true power output of
the amplifier. The Peak Watt Hold Mode allows the meters
to temporarily stay at the highest power output and then
slowly decay.

Installation
Caution: The MC602 Amplifier weight is 155 pounds
(70.31 kilograms). It requires two or more persons
to safely handle when moving the amplifier.
The MC602 can be placed upright on a table or shelf,
standing on its four feet. The
four feet may be removed
from the bottom of the
MC602 when it is custom installed as outlined below. The
four feet together with the
mounting screws should be
retained for possible future
use if the MC602 is removed
from the custom installation
and used free standing. It also
can be custom installed in a
piece of furniture or cabinet of
your choice. The required
panel cutout, ventilation cutout and unit dimensions are
shown.
Always provide adequate
ventilation for your MC602.
Cool operation ensures the
longest possible operating life
for any electronic instrument.
Do not install the MC602 directly above a heat generating
component such as a high
powered amplifier. If all the
components are installed in a
single cabinet, a quiet running
ventilation fan can be a definite asset in maintaining all
the system components at the
coolest possible operating
temperature.
A custom cabinet installation should provide the following minimum spacing dimensions for cool operation.
Allow at least 6 inches (15.24
cm) above the top, 2 inches
(3.81cm) below the bottom
and 1 inch (2.54 cm) on each
side of the amplifier, so that
airflow is not obstructed. Allow 22 inches (55.88 cm)
depth behind the front panel.
