METER RANGE
The METER RANGE switch has two positions: WATTS
and HOLD.
WATTS
In the WATTS position, the meter needle indicates the
variations in program loudness. Although the primary out-
put calibration of the meters is from 0.0027 watts (2.7
milliwatts) up to 270 watts, the rated power output of the
MC 7270, the additional indication to the right of the 270
watts mark, is 540 watts. While the MC 7270 cannot
reach this power level continuously it is possible for short
interval peaks to considerably exceed the 270 watts con-
tinuous rating.
HOLD
In the HOLD position, the meter needle locks to the
highest power peak in a sequence of peaks. The meter is
driven to maximum power, electronically held there until
a higher peak passes through the amplifier, which moves
the meter needle to a new indication. If no further peaks
are reached the meter needle will very slowly return to
its rest position (decay rate: 6 dB per minute).
POWER
The power switch turns the MC 7270 ON or OFF. The
switch does not control the power outlet on the back
panel. If you wish to control the AC power from a
preamplifier control center, leave the switch in the ON
position. Be sure the AC cord of the MC 7270 is plugged
into the controlled outlets on the rear of the preamplifier
control center.
OFF: In the OFF position the AC power to the amplifier
is turned off.
