Hold - The meter pointer is locked to the high-
est power peak in a sequence of peaks.
It is electronically held to this power
level until a higher power peak passes
through the amplifier. The meter point-
er 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 MC462 Power Output Meter
indicates the actual power 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 MC462, allows
selection of either the Bal-
anced or Unbalanced Input.
Refer to figure 12.
Power On
To have the MC462 automatically turn On or Off
when a Preamplifier or A/V Control Center turns On
or Off, rotate the power switch to
the Remote position. For manual
operation, rotate the power switch
to the On or Off position as desired.
Refer to figure 9.
Note: There must be a power con-
trol connection between the
MC462 and the Audio Pre-
amplifier (or A/V Control Center), in order for the
remote power turn-on to function.
Meter Selection
Rotate the meter mode switch to select the meter op-
eration mode you desire. Refer to
figures 10 and 11.
Lights Off - Meter lights are
turned off and the
meter will contin-
ue to indicate the
power output.
Note: When Power Control Input of the
MC462 is connected to an Audio
Preamplifier or A/V Control Center
with Remote Meter Illumination
Control, the Meter Illumination will
automatically be remotely con-
trolled (On/Off) with the METER
Switch set to the WATTS or HOLD
position.
Watts- The meters respond to all the musi-
cal information being produced by the
amplifier. They indicate to an accuracy
of at least 95% of the power output with
only a single cycle of a 2000Hz tone
burst.
Auto Off Switch
The MC462 incorporates Power Save Circuitry to
automatically place the MC462 into the power saving
Standby Mode approximately 30 minutes after there
has been an absence of an audio input signal.
When there is a Power Control Connection be-
tween the MC462 and a Preamplifier with Power Save
Circuitry, the AUTO OFF Switch is bypassed (located
on the Rear Panel of the MC462). Refer to figure 13.
In the event there is no
Power Control Connection
and the Power Save Circuitry
is activating inappropriately
relative to your specific use of
the MC462, place the AUTO
OFF Switch in the DISABLE position.
Note: If the Power Save Circuitry has switched Power
to the MC462 OFF, place the POWER in the OFF
Position and then in the ON position to reset the
circuitry.
