3. End Fire
The End Fire mode should be selected when the microphone is horizontally pointed (
) at the
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 information and the Up/Down height information being reversed. This mode is particularly
necessary when the microphone is mounted in a Rycote or on a fishpole and pointed directly at the
sound source.
To enable End Fire press the “End Fire” button - this will change the display to show the End Fire
status in the middle of the screen – further presses of the “End Fire” button will toggle the status
of End Fire on and off.
To return back to the main screen either press the “End Fire” button again or wait for the gain screen
to automatically time out.
4. Invert
The INVERT mode maintains the correct three-dimensional perspective in both surround and
stereo when the microphone is suspended upside down above the sound source ( ). Not
selecting this mode with the mic suspended will result in the Left/Right width information and
Up/Down height information being reversed. It is important to document the status of the Invert
switch when making B-Format recordings for later post production.
To enable Invert press the “Invert” button - this will change the display to show the Invert status
in the middle of the screen – further presses of the “Invert” button will toggle the status of
Invert on and off.
To return back to the main screen either press the “Invert” button again or wait for the gain screen to
automatically time out.
5. High Pass Filter
The variable High-Pass filter – second order Butterworth – will filter the incoming microphone
signals and will affect all output signals. Enabling the High-Pass filter is ideal for removing
unwanted low frequency rumble such as wind noise, etc.
To enable the High Pass Filter press the “High Pass Filter” button - this will change the display
to show the High Pass Filter status in the middle of the screen – further presses of the “High
Pass Filter” button will toggle the status of Invert on and off and the rotary controller will alter
the cut-off frequency.
To return back to the main screen either press the “High Pass Filter” button again or wait for the
gain screen to automatically time out.
