Product Description
The BBE 822 is an intelligent audio processor designed to solve a series of complex problems as described in the previous
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 -\-46Bu balanced line level applications, such as those found in
recording studios, large concert systems and industrial audio applications. The BBE 822 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 822
BBE'” is a process to be added oefore all other mixing of reverb, special effects or equalization. The BBE 822 should be
used to increase the clarity and intelligibility of the total finished mix or an individual track, i.e.: vocal or instrument.
Unlike many aural exciters and equalizers, the BBE 822 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 and 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 822 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-8dBu. The BBE 822 drives load impedances down to 600 Ohms and
supplies up to -h24dBu levels at which point it will clip. The BBE 822 accepts both unbalanced and balanced inputs and
supplies floating outputs on the XLR connections. The “tip” is hot on the V4 inch jacks. The inputs are active balanced and the
outputs are transformer isolated.
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 822 to roll off the noise first. Post¬
amplification of the BBE 822 is not necessary and not recommended, as the BBE 822 will drive any other device in the studio
audio chain to full level directly. This assumes that the BBE 822 is operating in the aforementioned fashion with line-levels.
