1. The heavy notes on the schematic denote the primary
signal path.
2. Unless otherwise noted, all voltages indicated on the schematics are measured under the following conditions: a. AC input at 120 volts, 50/60Hz. b. All voltages are +/-10% with respect to ground. A
high impedance (10 megaohm) voltmeter must be used.
3 . Unless otherwise specified:
a. Resistor values are in ohms. b. Capacitor values are microfarads (uF). c. Inductor values are in microhenries (uH).
4 . On PC board drawings, Square pad indicates:
a. Polarized Capacitors - Positive b. Diodes - Cathode c. Others - Pin 1

The power requirements listed are for each MC2KW Power
Module, two are required for each MC2KW Power Amplifier
2
Interconnect cables are supplied with the MC2KW Output Module and both MC2KW Power Modules connect to the MC2KW Output Module.
NOTES
5. WARNING
6. Soft startup procedure for servicing:
2
Parts marked with the symbol have critical characteristics. Use only replacement parts recom­mended by the manufacturer.
1. Interconnect output module and power modules 2 . Connect Output Module to 120VAC
3. Connect Power Modules to variac and set the output to zero.
4 . Turn Output Module power switch to on. (This will
energize the power relays in the Power Modules.)
5 . Gradually advance the variac to 120VAC while
monitoring the AC current.

REPACKING INSTRUCTION
MC2KW
OUTPUT
In the event it is necessary to repack the equipment for shipment, the equipment must be packed exactly as shown below. It is very impor­tant that the four feet are attached to the bottom of the equipment. This will ensure the proper equip­ment location on the bottom foam pad. Failure to do this will result in shipping damage. Also, to pro­tect the finish of the glass and metal surfaces it is advisable to place the MC2KW Output Module and the MC2KW Power Modules into the orginal pro­tective cotton blue bag before placing them into the shipping carton.
Note: Unless instructed otherwise, please return the McIntosh Custom Interconnect Cables along with the MC2KW Power Amplifier.
Use the original shipping carton and interior parts only if they are all in good serviceable condi-
tion. If a shipping carton or any of the interior part(s) are needed, please call or write Customer Service Department of McIntosh Laboratory . Please see the Part List for the correct part num­bers.
Note: The McIntosh MC2KW Output Module and
MC2HW Power Module use the same shipping carton.
