How to Operate
Power On
With the POWER Switch set to the REMOTE Position, the
MC207 will turn On or Off when an A/V Control Center
turns On or Off.
When connected to a McIntosh
A/V Control (or Preamplier) with
the Power Save Feature set active,
the MC207 will switch Off after a
period of inactivity. For additional
information please refer to the
McIntosh A/V Control (or Pream-
plier) Owner’s Manual.
For manual operation, place
the POWER Switch to the ON Po-
sition as desired. Refer to gure 8.
Note: There must be a power control connection between
the MC207 and the McIntosh A/V Control Center (or
Preamplier) in order for the remote power turn-on and
Power Save feature to function.
Meter Illumination
Rotate the METER LIGHTS Switch to select Meter Illumi-
nation On or Off. Refer to gure 9.
Note: When the MC207 is
connected to a McIntosh
MX132, MX134 or MX135
A/V Control Center with
a DB25 conductor cable,
the meter illumination will
automatically switch On
during the Loudspeaker Level
Setup Adjustment.
Impedance Switch
The MC207’s Dynamic Power Manager
®
Circuitry allows
for the connection of either 4 ohm or 8 ohm Loudspeakers
to its output terminals, while at the same time delivering
the same power output. Refer to gure 10.
Place the IMPEDANCE Switch to the po-
sition (4 ohm or 8 ohm) that matches the
impedance of the connected Loudspeakers.
In the event that some of the Loudspeakers
in the system are of different impedance,
use the impedance of the Left and Right
Front Loudspeakers to set the IM-
PEDANCE Switch position. Refer to
gure 11.

The MC207 Power Output Meters are calibrated to allow
for the direct reading of either the Power Output in Watts
or Decibels going to the Front Left, Center and Right
Loudspeakers. The meters respond to all the musical infor-
mation being produced by the amplier. They indicate to
an accuracy of at least 95% of the power output with only a
single cycle of a 2000Hz tone burst. Refer to gure 12.
