Powering
The MTR231 is a condenser microphone and therefore requires 48V phantom
power. Phantom power is provided by a mixer's preamplifier channel or if neces-
sary, an external phantom power supply and sent to the microphone along a bal-
anced microphone cable.
To ensure the longevity of your equipment, and is good mixing etiquette, always
turn down the master fader and monitor controls to zero when switching the phan-
tom power on or off.
Poor microphone performance can be attributed to phantom power issues. If you
notice that the microphone is exhibiting reduced signal output, increased noise, or
decreased headroom (distortion), there may be an issue with the phantom power
supply or the microphone cables.
Setting the Microphone Level
When connecting the MTR231 to a mixer, use a balanced cable and be sure that
the input is balanced and connected to a channel that is set for microphone level.
Also, be sure that the phantom power is engaged. Most mixers and recorders of
reasonable quality will offer a microphone input with mic trim (usually called Trim
or Gain) control. The purpose of the mic trim control is to optimize the amount of
good signal over any noise that may be associated with the mixer's electronics. A
good mic pre with trim will have a peak or clip indicator. To set an optimal level
on the mic, place the MTR231 in front of the desired sound source and slowly
raise the mic trim control until you see the PEAK LED light up. Then, turn the mix
trim control down until the LED does not light any more. For most applications,
the ideal setting is to set the trim control as high as possible without lighting the
peak indicator.
