Stereo Miking Techniques

1. The phase reverse switch on the I/O module of the mixing console

Reverse the phase of the signal by 90 degrees

Coincident

Both set to omnidirectional

Different makes and models

Different distance from the sound source

13. A method using a pair of microphones, placed 10 feet apart, would be known as

15. Stereo LP phonograph records were introduced in

1969

1947

1957

1927

1983

16. A main advantage of an XY technique over a spaced pair technique would be...

Better mono compatibility

A wider stereo image

Better high frequency response

Better low frequency response

Cooler name

17. The Decca Tree was created by engineers working for

Neumann

Carnegie Hall

Bell Labs

Disney

18. An advantage of the MS method over XY is

XY has very poor localization characteristics

The XY method is not mono compatible

MS can give a better high frequency response to sound sources directly in front of the array

XY is only good for sound sources with a wide large strero image

MS does not require the use of condensor microphones

Inter-Aural Intensity differences

Inter-Aural Time differences

Phase differences

22. When using the XY technique, if the included angle of the capsules (pointing away from each other) is too narrow ...

You will end up with a mono signal

You will get a hole in the center of your stereo image

You will get phase cancellations in the 300Hz - 400Hz range

You will have to phase reverse the left channel

None of the Above

23. Which technique requires 2 PZM mics seperated by a foam block?
