General Notes

1.Caution: To prevent electrical shock make sure that the AC POWER CORD IS NOT CONNECTED TO THE MC2102 when inserting or removing Vacuum Tubes, as there are hazardous voltages present at the pins of the Tube Sockets.

2.When Vacuum Tubes are installed or removed, reattach the Tube Cover with the Original Tube Cover Screws.

3.If the MC2102 has been On, please allow the Hot Vacuum Tubes to cool first before removing them.

4.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.

5.For additional connection information, refer to the owner’s manual(s) for any component(s) connected to the MC2102.

6.It is very important that loudspeaker cables of adequate size be used, so that there will be minimum power loss. The size is specified in Gauge Numbers or AWG, (American Wire Gauge). The smaller the Gauge number, the larger the wire size.

Connection Terminals will accept up to a 8 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.

7.Pin configuration for the XLR Balanced Input connectors on the MC2102:

PIN 1: Shield or ground

PIN 2: + input

PIN 3: - input

Now you can take advantage of traditional McIntosh stan- dards of excellence in the MC2102 Power Amplifier. Two 100 watt high current output channels will drive any high quality loudspeaker system to its ultimate performance.

The MC2102 reproduction is sonically transparent and ab- solutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Performance Features

·Power Output

The MC2102 consists of two separate power amplifier channels, each capable of 100 watts into 2, 4 or 8 ohm loudspeakers in stereo. It may also be operated in mono at 200 watts into 1, 2, 4, 8 or 16 ohm loudspeakers.

·Bifilar Wound Transformers and Output Circuit The Power Output Sections utilize the famous McIntosh Patented Unity Coupled Circuit with a Bifilar Wound Out- put Transformer for low distortion, extended frequency re- sponse and cool operating output tubes.

·Balanced and Unbalanced Inputs

Balanced connections guard against induced noise and al- low long cable runs without compromising sound quality.

·Illuminated Power Meters

Two accurate, peak responding output meters continuously indicate the power delivered by each channel. A Peak Hold Meter Mode indicates the maximum power reached over a given time span. The meter illumination can be turned off so as not to detract from the listening environment, if de- sired.

·Gold Plated Connectors and Tube Socket Contacts Gold Plated Input Jacks and Output Binding Posts provide trouble free connections. Ceramic tube sockets with gold plated contacts provide protection from atmospheric con- tamination. Output Tube Sockets include Air-Pipe cooling at their bases.

·Glass Front Panel and Super Mirror Chassis Finish The famous McIntosh Illuminated Glass Front Panel and the Stainless Steel Chassis with Super Mirror Finish en- sures the pristine beauty of the MC2102 will be retained for many years.
