Split Chamber
General Description
The Splii Chamber program provides several presets which can be loaded into
any Dual Mono or Cascade setup. In the Dual Mono setups it passes audio Mono
In-Mono Out. In the Cascade setups, audio is routed Mono In-Stereo Out. The
Sptii Chamber program can simulate many diff erent types of acoustic spaces or
mechanical devices.
Th Split Chamber algorithm is great on anything. SIZES of 25 and larger set a
loweracousticdensity. SHAPand SPRD helpcreate the illusionof largerspaces
whicle using short reverb times. As in the Random Hall algorithm, the LINK
parameter couples SIZE to the RTIM and SPFZD.
Unlink provides a method of
setting stable RTIM and SPRD values, then adjusting SIZE to set the right
density and ‘krning”. Split Chamber is bright by design, so you may want to use
lower values of TDCY - maybe even as low as 1 .OkHz or 5OOHz.
The randomization circuit in Split Chamber is designed to reduce coloration and/
or frequency nodes caused by low frequency input. If you want to create your
own special Chambers or Halls, you should keep RAND set to 90 or 95.
Typically, SIZES of 14-24 meters with TDCYs higher than3.4kHz will emulate
bright sounding metal plates. Rememberto set SHAP and SPRD to extremely
low values to maintain the explosiveness of the reverb decay. Because plates
are very diiuse, any preset mimicking a plate should have DIFF set relatively
high (70-80) while BASS is kept to some value less than 1.2kHz.
DIFF and PDLY precede the reverberator. When Chamber programs are loaded
into Dual Mono setups, the audio will be Mono In-Mono Out. When loaded into
Cascade setups, audio is routed summed Mono In-Stereo Out.
