1. LED Bargraph
8 segment LED bargraph meter displays the mic level over a range of -30dB to +12dB
and has a peak hold function.
2. Gain
A switched gain control adds further gain to the microphone in 3dB steps. There are 14
steps with a total of 42dB available. A switch has been selected in preference to a
potentiometer to provide excellent level matching of the four capsule signals.
3. End Fire
The End Fire mode should be selected when the microphone is horizontally pointed at
the sound source (
sound source ) as you would with a flashlight.
Selecting End Fire maintains the correct three-dimensional perspective in both surround
and stereo when the mic is used in the horizontal position.
If you do not select this mode when the microphone is horizontal it will result in the
Front/Back depth and Up/Down height information being reversed. When making B-
Format recordings for later surround or stereo post production with the Surround Zone
software or hardware digital DSF-3/analogue SP451 processors, it is important to
document the status of the End Fire switch. This mode is particularly necessary when the
microphone is mounted in a Rycote or on a fishpole and pointed directly at the sound
source.
