Introduction
·
Power Output
The MC206 consists of six Power Amplifier Channels,
each capable of 200 watts into 4 ohm or 120 watts into 8
ohm loudspeakers with less than 0.005% distortion.
·
High Current Output
A peak output current of 25 amperes per channel ensures
that the MC206 will successfully drive high quality loud-
speakers such as McIntosh for a truly exciting sound expe-
rience.
·
Power Guard and Sentry Monitor
The MC206’s Patented McIntosh Power Guard Circuits
prevent each of the amplifier channels from being
overdriven into clipping, with its harsh distorted sound that
can also damage your valuable loudspeakers. The Sentry
Monitor Power Output Protection Circuits ensure the
MC206 will have a long and trouble free operating life.
·
Illuminated Power Meters
Three Front Panel Illuminated Power Output Meters can be
selected to precisely indicate the power output of each of
the six channels.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MC206 Power Amplifier. Six
200 watt high current output channels will drive any high
quality loudspeaker system to its ultimate performance.
The MC206 reproduction is sonically transparent and abso-
lutely accurate. The McIntosh Sound is “The Sound of the
Music Itself.”

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 owner’s
manual(s) for any component(s) connected to the MC206.
3. The MC206 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. The
MC206 Loudspeaker Connection Terminals will accept up to a
10 AWG 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. In the event that the MC206 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 MC206 has returned to a safe operating
temperature, normal operation will resume.
6. The Multi-Channel Input DB25 Connector allows for easy
connecting of a McIntosh MX130/132 or C39 A/V Control
Center, Audio and Power Control connections, to the MC206.
If a McIntosh MSE1 Surround Expander is connected to the
MX130/132 or C39, then discrete Audio and Power Control
Cables should be used between them and the MC206. The
Diagram and Pin Identification list for the Multi-Channel
Input is as follows:
