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.
5. Hi-Pass
100Hz hi-pass filter is available to attenuate unwanted low frequency rumble or wind
noise. PLEASE NOTE: THE HI-PASS FILTER IS ACTIVE ACROSS BOTH THE
STEREO AND B-FORMAT OUTPUTS.
6. Pattern
The Polar Pattern control is continuously variable ranging from Omni through Sub-
Cardioid, Cardioid, Hyper-Cardioid to Figure-of-eight and sets the polar patterns used for
the stereo pair.
7. Mid Side
When the Mid/Side switch is engaged the stereo outputs will be M/S encoded. The Left
output channel provides the Mid signal and the Right output channel provides the Side
signal.
8. Width
Offers continuous adjustment of the stereo width from mono (‘0’) through to wide angle
stereo (‘10’).
9. Headphone Monitoring
Front panel headphone monitoring is provided with a continuously variable volume
control. The headphone section monitors the Left/Right stereo output. Connection is via a
stereo 1/4 inch jack socket (TRS) and is for use with headphones having an impedance of
100 ohms or greater.
