XLR Connectors
Below is the Pin configuration for the XLR Balanced Input Connectors on the MC205. Refer to the diagram for con- nection:
PIN 1: Shield/Ground
PIN 2: + Output
PIN 3: - Output
Power Control Connector
The MC205’s Power Control Inputs receive On/Off signals of +5 volts. An additional connection
is for controlling the illumination of 
the MC205 Power Output Meters.
The 1/8 inch stereo mini phone plug
connects to a McIntosh A/V Control Center Power Control Output.
Note: The Power Control Connecting Cable is available from the McIntosh Parts Department:
Data and Power Control Cable Part No.
Six foot, shielded 2 conductor, with 1/8 inch stereo mini phone plugs on each end.
Introduction
Now you can take advantage of traditional McIntosh stan- dards of excellence in the MC205 Power Amplifier. The five channel Power Amplifier produces a power output of 200 watts per channel and will drive quality Loudspeakers to a high level of performance. The MC205 reproduction is sonically transparent and absolutely accurate. The McIn- tosh Sound is “The Sound of the Music Itself.”
Performance Features
• Power Output
The MC205 consists of five Power Amplifier Channels, each capable of 200 watts into 4 ohm or 8 ohm Loudspeak- ers with less than 0.005% distortion.
• Power Guard
The patented McIntosh Power Guard Circuit prevents the amplifier from being over driven into clipping, with its harsh distorted sound that can damage your valuable Loudspeakers.
• Dynamic Power ManagerTM
The MC205’s Dynamic Power Manager (DPM) circuitry allows for the connection of either 4 ohm or 8 ohm Loud-
speakers, while at the same time delivering identical power output. A peak output current of 25 amperes per channel ensures that it will successfully drive high quality Loud- speakers such as McIntosh, for a truly exciting sound experience.
• Balanced and Unbalanced Inputs
Balanced connections guard against induced noise and al- low long cable runs without compromising sound quality.
• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection circuits ensure the MC205 will have a long and trouble free operating life.
• Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MC205 are peak responding, and indicate the power output of the amplifier.
• Power Control
The McIntosh Power Control Circuit allows for remote
• Special Power Supply
A regulated Power Supply and a very large Toroidal Wound Power Transformer, ensures stable noise free op- eration even though the power line varies.
•Fiber Optic Solid State Front Panel Illumination The even Illumination of the Front Panel is accomplished by the combination of custom designed Fiber Optic Light Diffusers and extra long life Light Emitting Diodes (LEDs). The glass Front Panel ensures the pristine beauty of the MC205 will be retained for many years.
