Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

Selection of pick-up patterns
Switch C serves to set the mic to five different pick-up patterns:
Omnidirectional
The push-pull transducer incorporated into the MKH 80 reduces the mic´s directivity to a minimum for high frequencies. The mic has a neutral response to direct and diffuse signals. This feature provides a sense of space and depth and allows large sound sources to be miked. For close-miking, sound reproduction does not become overbrilliant or shrill. No proximity effect.
C
Wide-angle cardioid
The wide-angle cardioid pick-up pattern is a combination of the omnidirectional and the cardioid pickup pattern. A rear attenuation of 10 dB allows a moderate attenuation of diffuse signals from the rear and thus a good reverberation balance for longer distances to the sound source, even in rooms which are acoustically less perfect. Like the omnidirectional pickup pattern, the wide-angle cardioid pick-up pattern is particularly well suited to mike large sound sources. For close-miking, the mic´s bass emphasis is less high than with the cardioid pick-up pattern. 16
