3.2 Input Section
3. 2.a. +48v
Phantom power switch for condenser microphones or
direct injection boxes.
3.2.b. pad
Using this switch inserts a 20dB attenuation into the
mic input amp. If the signal source is too loud, you use
this in conjunction with the mic/line gain to allow you
more control on the channel faders.
3.2.c. phase
Use this switch to reverse the phase of any mic input
coming from a mic or signal that may be out of phase with
other mics or signals. A good way to check for "out of
phase" is to push the mono switch on the master section
and listen closely to the mix. If you hear " something
that sounds strange or completely missing in your mix,
push the phase switch on those channels suspected. If
the sound returns or sounds better, that channel was out
of phase with the others. You can have an acoustical phase
cancellation as well when using multiple mics on the same
signal such as drums, vocals, horns, strings, etc.
Physically moving mics inches will in most cases correct
an acoustical phase cancellation.
3.2.d. gain (very important)
This is the single most important control on your
console.
When this control is set properly, you can achieve the
very best signal to noise ratio and get the most headroom
needed for high quality recordings. After plugging in a
mic, push the "channel to pfl mode" switch on the master
section. Now push the solo switch just above the
channel fader on the channel you're setting, (with the
channel fader off). Turn the gain control clockwise until
you see a "0" output level on the master meters. Now slide
up the channel fader to "0".
Remember, if the signal source gets louder or softer, you
may have to go back and check this setting. The volume can
also change if you boost or cut in the equalizer section.
Be sure the signal being miked stays the same volume when
you start recording, or you'll need to go back and do all
this again.
IT'S IMPERATIVE TO DO THIS WITH EVERY MICROPHONE INPUT
OR LINE INPUT TO ACHIEVE THE HIGH QUALITY AND SPECS D&R
PRODUCTS ARE KNOWN FOR.
NOTE: Do not use the output meter on the same module for
setting levels. It will read higher.
3.2.e. line
Switches the channel input to line level. The line input has
its own input jack and is controlled by the (dual) Gain
control.
