level of the input source with the INPUT TRIM control,
otherwise the sound will be distorted.

main right and center channels while maintaining overall

H Rec Out Selector
Selects the source to be recorded to a tape deck 1 or

the setting of the INPUT SELECTOR decides the source to
be recorded to a tape deck or VCR.

such as a camcorder to these jacks. If the connected video
equipment has a S video output terminal, connect it to the S
VIDEO jack to obtain a high resolution picture. The source

SELECTOR and REC OUT selector.
