Product Description
The BBE 822A is an intelligent audio processor designed to solve a series of connplex problems as described in the previ¬
ous section. It is, however, very simple to set up and operate and once installed will function flawlessly without further attention.
It is a dual channel, rack-mountable device for use in H-4dBu balanced line level applications, such as those found in
recording studios, large concert systems and industrial audio applications. The BBE 822A takes up one EIA standard rack
space of 19 inches width and 1.75 inches height (1U). There are two completely separate channels to allow for either full
stereo program or two independent mono channels, such as separate processing for a snare drum tape track in channel
A and a synthesized bass track in channel B.
BBE applies different phase correction algorithms to three separate frequency bands. A variable front panel control for
each channel allows the user to adjust the amount of process desired.
Using Your New BBE 822A
BBE is a process to be added before all other mixing of reverb, special effects or equalization. The BBE 822A should
be used to increase the clarity and intelligibility of the total finished mix or an individual track, ie. vocal or instrument.
Unlike many aural exciters and equalizers, the BBE 822A will not add any extra noise or harmonics to the sound. Thus,
there will be no future problems in duplication or mastering caused by aberrant high frequency distortion. Since the BBE
technology is a single-stage process, there is no need for encoding or decoding.
Always "A - B" the processed to unprocessed sound with the process in/out switch to adjust the amount of processing
required.
Things to Remember
The BBE 822A is designed to work in a line-level environment. The program average levels feeding the input of the unit
should be around “0” VU or anywhere from -20dBu to -i- 8 d B u . The BBE 822A drives load impedances down to 600
Ohms and supplies up to +23dBu levels at which point it will clip. The BBE 822A accepts both unbalanced and balanced
inputs and supplies floating outputs on the XLR connections. Both the inputs and outputs are active balanced while having
the tip on V 4 " jacks hot.
If the program material has excessive background noise, the noise may be modulated with the program. In this case,
an equalizer or other type of noise reduction system may be inserted in front of the BBE 822A to roll off the noise first.
