Surround sound and the PRE

40
It would seem that there is no way to properly integrate a surround sound
processor with a preamplifier for a high quality, dual-purpose system.
The PRE solves this dilemma by virtue of a specially designed surround sound
processor interface. The
tape2/ssp
• as a normal tape2
inappropriate for a surround sound processor)
• as an input (which passes the front Left and Right outputs of
ssp
your surround sound processor through to the power amplifier
without any change in volume or balance)
• the PRE may be "toggled" between these two modes by pressing
and holding the
tape2/ssp
color (amber for
tape2
When using the " " input of the PRE, the volume and balance controls are
ssp
defeated and the preamplifier operates in unity gain mode. This feature yields
control over the volume of the various loudspeakers to the surround sound
processor, where it belongs during surround sound playback.

When you are ready to return to normal, two-channel stereo, simply select any
other input on the PRE. Your video sources may then be connected to your
surround sound processor while your music sources are connected to the PRE.
(Incidentally, if you wish to send a music signal to your surround sound pro-
cessor for special effects, simply select it as the record path's source and moni-
tor the ssp input on the main path. Doing so will send the music on a "detour"
through the processor, much as it would if it were routed to a tape deck for
recording.)
Thanks to this design innovation, it is possible for the first time to cor-
rectly integrate a surround sound processor with a preamplifier, send-
ing the processor's Left and Right outputs through the PRE (and on to the
power amplifier for the main front speakers). Since the output level of these
