System Setup
VCR considerations
•Some combination TV/VCR units may not work with 3•2•1 Series II home entertainment systems. Please refer to your TV/VCR owner’s manual for information.
•A stereo VCR is required for optimal sound performance. If your VCR has only one audio output and is not labeled Stereo or Hi-fi, you have a mono VCR. You will need a Y-adapter cable (available at electronics stores) to connect audio to the media center. For this setup, you will need to select “Mono decoding” (see “TV, CBL-SAT, and AUX settings menu” on page 43) so your 3•2•1 system will simulate surround sound effects from a mono source. Otherwise, you will hear mono sound from both speakers.

TV (S-video)-to-media center connections
IMPORTANT
If you use S-video to connect your TV to the media center, you must also use S-video to connect all other devices (such as a cable box and VCR) to the media center.
Making S-video connections (higher quality video)
An S-video input jack, provided on many TVs, delivers a higher quality TV picture than the composite video output connection shown in Figure 11. For this connection you will need an S-video cable which can be purchased from your Bose dealer or a local electronics retailer.
•Insert one end of the S-video cable into the S-Video OUT jack on the media center (Figure 14).
•Insert the other end of the S-video cable into the S-VIDEO IN jack on your TV.
