Condenser microphones
– Condenser microphones feature excellent sound quality, but
require a power source to operate. A few use internal batteries. Most expect to receive
power from the mixer’s microphone input (this is called,
phantom power
). Your mixer can
provide phantom power at any or all microphone inputs.
To select phantom power:
Move the switch corresponding to the condenser mic’s channel to the
ON
position as shown.
If condenser mics get moved among several channels, set
all
their switches to
ON
. Mics that
use phantom power won’t work without it. Dynamic microphones don’t need phantom
power, but usually tolerate it. Switch Phantom Power
OFF
for wireless receivers unless their
instructions direct otherwise.
Input Gain
– Each input’s
gain
(amplifying ability) can be set to better match levels of
different mics. A rotary switch above each input connector adjusts that input’s gain in four
10dB choices. Adjust if needed with a small screwdriver. Generally, condenser mics are
“hot” and can use a lower gain setting. Dynamic mics typically need more gain – the older
the mic, the more gain needed. We suggest adjusting each input’s gain preset so that you
get a satisfying volume with its front panel control between half and 2/3 up.
Stereo Sources
– Use a “Y” adapter to combine the
Left
and
Right
channel of stereo sources
(such as CD players). Connect the resulting mono output to one of the two auxiliary inputs
at the mixer.
Multiple sources
– If you have more than two auxiliary (non-microphone) sources, we
do
not
recommend combining them with “Y” adapters. Different sources may not perform
properly if paralleled with “Y” adapters. Instead, configure an unused MIC input (such as
MIC 10
) as an extra music input – See page 29.
