Caution: The MC2301 Amplifier weight is 116 pounds
(52.6 kilograms). It requires two or more per-
sons to safely handle when moving the ampli-
fier.
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 MC2301.
3. The MC2301 mutes the speaker output for approxi-
mately fifteen seconds when first turned on.
4.
The MC2301 incorporates the very latest in Fully Bal-
anced Circuitry. As a result, the Loudspeaker Nega-
tive Connections are above chassis ground. Do not com-
bine any connections together, ground them or connect
with another MC2301 or other Power Amplifier.
5. For the best performance and safety it is important
to always match the impedance of the loudspeaker
to the Power Amplifier connections. Refer to step 5
on page 10.
Note: The impedance of a Loudspeaker actually var-
ies as the Loudspeaker reproduces different
frequencies. As a result, the nominal impedance
rating of the Loudspeaker (usually measured at
a midrange frequency) might not always agree
with the impedance of the Loudspeaker at low
frequencies where the greatest amount of power
is required. Contact the Loudspeaker Manufac-
turer for additional information about the actual
impedance of the Loudspeaker before connecting
it to the McIntosh MC2301.
5. When discarding the unit, comply with local rules
or regulations. Batteries should never be thrown
