Navigating the Front Panel
How to Operate
Power Control
The POWER CONTROL is located on the Front Panel
of the MC3500. Set the Control to the
REMOTE Position. Refer to figure 10.
The MC3500 Power Amplifier will
turn ON or OFF as the Preamplifier it
is connected to (via the Power Control
Connection) turns On or Off . For
manual operation, place the POWER
CONTROL to the ON Position as desired. The LED
indicator located on the Front Panel is illuminated
when the MC3500 is connected to an active AC
Outlet.
When the MC3500 is first switched On, there is a
Warmup period of time during which no sound will be
heard and the WARMUP LED will illuminate. During
this period, the Power Output Meter needle will
gradually rise to show the warmup percentage. After
the needle reaches 100%, the MC3500 will begin
playing sound, the WARMUP LED will switch off,
and the needle will return to displaying the appropri-
ate Output based on the Meter Control Knob position
(see below).
Meter Control
The Meter Control Knob changes how the Power
Output Meter behaves. If the Knob is set to WATTS,
the Meter will continuously respond to and display
the current Output of the MC3500.
Refer to figure 11.
If the Knob is set to HOLD, the
Meter will display the highest peak
Output in a series of peaks, until a
greater peak is read. If no greater
peak is read, the Meter will begin to
lower at a rate of approximate 6dB per minute.
