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!

7. INPUT Jack
This jack accepts input signals (coming from a guitar, some other musical instrument, or another effects unit). * The INPUT jack doubles as power switch. Power to the unit is turned on when you plug into the INPUT jack; the power is turned off when the cable is unplugged. When not using the effects unit, be sure to disconnect the plug from the INPUT jack.
8. REVERB Knob
This adjusts the amount of reverb applied to the sound.
9. LEVEL Knob
This adjusts the volume of the effect sound.
