VCR considerations

• Some combination TV/VCR units may not work with 3•2•1 GSX 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, 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 page53) so your 3•2•1 GSX
system will simulate surround sound effects from a mono source. Otherwise, you will hear
mono sound from both speakers.
Advanced setup options
The 3•2•1 GSX home entertainment system provides connections for producing higher
quality video and audio. The following describes how to use these connections.

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.
1. Insert one end of the S-video cable into the S-Video OUT jack on the media
center (Figure 14).
2. Insert the other end of the S-video cable into the S-VIDEO IN jack on your TV.

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.
