19 POWER, PEAK, & LEVEL METER
POWER
This blue LED comes on when the power of the
mixer is being turned on.
PEAK
PEAK LEDs will light up to indicate possible signal
overload.
LEVEL METER
These level meters offer visual display of the MAIN
output level when the “ TO PHONES” button at 2T RTN
section is released. With 3-segment LEDs consisted
of green, yellow and red LEDs, they begin from -20dBu
to +6dBu. This meter is calibrated to 0 = +4 dBu, as
indicated on the panel.
20 POWER SOCKET
This 3-PIN socket connects to an AC Adaptor that
sends power into the mixer. Having an external power
supply helps to avoid possible power interference and
guarantees good sound quality. Before connecting to
the external power supply, please make sure the
voltage of the AC power supply is exactly the one used
in your country. The chart below lists the part number
and the voltage of the power supply.
21 POWER SWITCH
Turn the unit on with this switch. Turn down the
MAIN out level control to the minimum level before
switching on the power. The blue LED at the front panel
will come on when power is being turned on.
MASTER SECTION
14 +48V PHANTOM POWER
Condenser microphones need phantom power.
Therefore, you should turn it on when using condenser
microphones. Located at the control panel, a master
switch provides total control over two mic input. Turn
all level controls to the minimum level before switching
on phantom power, and always plug in microphones
before turning on phantom power. Doing so would
prevent harming the equipment as well as avoid
producing unwelcome noise.
WARNING: Do not use unbalanced microphone with
Phantom Power on; it might damage your
microphone.
15 TO L/R
2T RTN signal will be sent to main out if you push
this button.
16 TO PHONES
When this button is depressed, the signal from 2T
RTN is sent to the PHONES output, and the signal level
is displayed on the LED LEVEL METERS.
17 PHONES
Adjust this knob to control the signal level going to
the headphones (PHONES) output.
18 MAIN L/R LEVEL CONTROL
A rotary level control determines the final output
level of the final level of MM502. Its setting will also
affect the final output level of 2T REC.
