How to Operate the MC1201

How to Operate the MC1201

Power On

To have the MC1201 automatically turn On or Off when a

control center turns on or off,

rotate the power switch to the

remote position. For manual op-

eration, rotate the power switch

to the On or Off position as de-

sired. Refer to figure 8.

Note: There must be a power

control connection

between the MC1201 and

the McIntosh Control

Center, in order for the remote power turn-on to

function.

Meter Selection

Rotate the meter mode switch to select the meter operation

mode you desire. Refer to figures 9 and 10.

Lights Off - Meter lights are

turned off and the

meter will con-

tinue to indicate

the power output.

Watts- The meters re-

spond to all the

musical informa-

tion being pro-

duced by the am-

plifier. They indicate to an accuracy of at least

95% of the power output with only a single

cycle of a 2000Hz tone burst.

Hold - The meter pointer is locked to the highest

power peak in a sequence of peaks. It is elec-

tronically held to this power level until a

higher power peak passes through the ampli-

fier. The meter pointer will then rise to the

newer higher indication. If no further power

peaks are reached, the meter pointer will very

slowly return to its rest position or lower

power level. The decay rate is approximately

6dB per minute.

Note: The MC1201 Power Output Meter

indicates the actual wattage delivered to

the loudspeakers by responding to the

combination of current and voltage

output.

Input Mode Switch

The Input Mode Switch, which is located on the Rear

Panel of the MC1201, allows

you to select either the Bal-

anced or Unbalanced Input. Re-

fer to figure 11.
