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!

killing ground lift switch that (unlike other acoustic preamp/DI's) works even when phantom power is applied to the preamp.
QUICK START
1. If you are using the XLR output, set the Pre / Post switch to "Post" position. 2. Adjust the Input gain so that the Clip/Low Battery light barely flashes with strong strumming. 3. Strum hard and raise the Smooth knob up until you hear the Compressor take the percussive edge off your highs. 4. Phase: Flip the Phase switch to the position that sounds best and suppresses mid-bass feedback 5. Notch: To squelch deep bass feedback, adjust the Notch dial between 1:00 and 2:30. The Notch is off in the 7:00 position.
