Parasound Halo C1 Controller - Manual (Page 48)

Connecting Audio Amplifiers to the C 1
The basic home theater setup is 5.1 channels: Front (left and right), Surround (left and right) and
Center (front), plus a subwoofer (the “.1” in the array). That’s sufficient for the Dolby Digital, and
DTS soundtracks on most DVDs and the Dolby Surround soundtracks on most videocassettes,
Laserdiscs, and broadcasts.
The two surround back channels are optional, as the diagram indicates. They are needed for optimum
surround from 7.1-channel Dolby Digital Surround EX or DTS ES soundtracks and from 7.1-channel
sources that use the 7.1-channel analog inputs. However, if you have surround back speakers, the C 1
will extract ambience information to feed them when you select the DTS Neo:6 Cinema or Neo:6
Music modes (which also work with non-DTS program material). If your system does not yet have
surround back speakers, 7.1-channel soundtracks will be reproduced as regular 5.1-channel surround.
As you can see from the diagram, if you start with a five-channel amp and want to expand your sys-
tem later, you can add a stereo (two-channel) amp to drive the additional speakers.
Amplifier Alternatives
The amplifier setup shown above – a five-channel amplifier and an optional two-channel amp,
both connected to the 7.1-channel unbalanced analog outputs -- is far from mandatory. A five-
channel amplifier is convenient, compact, and cost-effective, a two-channel amp is a convenient
way to add a pair of channels, and most amplifiers have unbalanced inputs.
If you own a two-channel amplifier that’s better or more powerful than your five-channel amplifi-
er, we recommend you use it for the left and right front channels to assure the best possible
sound when playing stereo music.
It would also be possible to use the balanced outputs on the C 1, as long as your amplifiers
have balanced inputs. For powered subwoofers, unbalanced connections are commonly used,
as few subwoofers have balanced input jacks.
