How to Operate the MC205
How to Operate the MC205
Power
With the POWER Switch set to the OFF/REMOTE Posi- tion, the MC205 will turn On or Off when
an A/V Control Center turns On or Off. For manual operation, place the POWER Switch to the ON Position as desired. Refer to figure
8.
Note: There must be a power control connec- |

Meter Illumination
Place the METER LIGHTS Switch to the ON position for Illuminated Meters or place the switch
to the Off position for no Illumination. When Power Control Input ZA (Zone
A only) of the MC205 is connected to a McIntosh A/V Control Center or Pream- plifier with Remote Meter Illumination Control, the Meter Illumination will auto- matically be remotely controlled (On/Off) with the METER LIGHTS Switch to set to the ON position. Refer to figure 9.
Impedance Switch
The MC205’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 figure 10. Place the IMPEDANCE Switch, located on the rear panel, to the position (4 ohm or 8 ohm) that matches the impedance of the connected Loudspeak-
ers. In the event that some of the Loud-
speakers in the system are of different impedance, use the impedance of the Left and Right Front Loudspeakers to set the IMPEDANCE Switch position. Refer to
figure 11.
Power Output Meters
The MC205 Power Output Meters are calibrated to allow for the direct reading of either the Power Output in Watts or Decibels for Loudspeakers connected to Channels 1, 3 and 5. The meters respond to all the musical information being produced by the amplifier. They indicate to an accu- racy of at least 95% of the power output with only a single cycle of a 2000Hz tone burst. Refer to figure 12.
