Lexicon CP-1 Theory Of Operation page 18

The effectiveness of the ambience simulation is heavily dependent on the
source material and the playback room. If the playback room is large and
reverberant, its reflections may dominate those generated by the processor.
Carpet, drapes and furniture can all be used to break up or absorb undesir-
able reflections, making it easier to hear the processor's output. The balance
between the side, rear and front speakers is also very important. If the
channels are set up properly, no single speaker will be audible by itself.
Although the ambience effect in Nightclub and Concert Hall can provide
some reverberation (adjustable with the Liveness parameter), for long
decay times it is better to use the reverb effects: Cathedral and Church. The
Concert Hall ambience is not intended to be used on material which is more
appropriate to a smaller ambience, such as a small hall or a club. Highly
percussive material is almost always better in Nightclub, which is quite
successful in livening and expanding popular music.

Placement of side loudspeakers is criti-
cal! Placement B sounds much better
than A, especially when the room is well
damped.
