Checks and Alignments
The SoundField System produces near perfect figure-of-eight patterns making it possible to
substantially check the microphone using speech tests only, preferably using headphones.
Set the microphone on a stand or boom at a comfortable height to walk around but low enough to
get your head over the top. Set the controls as follows:
.
1 Solos normal (off)
2 Osc off
3 Invert/End to suit microphone position
4 Gain to give comfortable listening level
5 Azimuth 0
6 Elevation 0
7 Dominance 0
8 In de-selected
9 Rec de-selected
10 Tape de-selected
11 Stereo pattern figure-of-eight
12 Stereo angle 0°
First solo each capsule and listen to one at a time to check the continuity of the microphone lead.
If a speech check is conducted at this point it should be possible to ascertain the direction of each
individual capsule in the horizontal and, if the test room is not too reverberant, the vertical.
LB - = left back down
LF + = left front up
RF - = right front down
RB + = right back up
Left and right are defined as being the left and right hand side of the stereo picture ie they will be
reversed if you face the front of the microphone.
This test is optional provided that a roughly equal signal is received from each capsule. (Bearing in
mind that two face forwards and two face backwards and that two face upwards and two face
downwards).
De-select all the solo buttons and select the SoundField in button.
The unit is now set to produce a forwards facing mono figure-of-eight.
