General Notes
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 MC202.
3. The MC202 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 MC202: PIN 1: Shield or ground
PIN 2: + input
PIN 3: - input
6. In the event that the MC202 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 MC202 has returned to a safe operating
temperature, normal operation will resume.
Introduction
Now you can take advantage of traditional McIntosh standards of excellence in the MC202 Power Amplifier. Two
200 watt high current output channels will drive any high
quality loudspeaker system to its ultimate performance.
The MC202 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is The Sound of the
Music Itself.
Performance Features
· Power Output
The MC202 consists of two separate power amplifier channels, each capable of 200 watts into 2, 4 or 8 ohm speakers
with less than 0.005% distortion.
· High Current Output
A peak output current of 50 amperes per channel ensures
that the MC202 will successfully drive high quality loudspeakers such as McIntosh for a truly exciting sound experience.
· 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 MC202 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 Meters on the MC202 are
peak responding, and indicate the 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.
