Product Description; Things To Remember - BBE 422A User Manual

Product Description
The BBE 422A 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 -lOdBu unbalanced line level applications such as those found
in semi-professional and musical instrument applications. The BBE 422A takes up one EIA standard rack space of 19
inches width and 1.75 inches height (1U). There are two separate channels to allow for either full stereo program or two
independent mono channels: A house P.A. mix feed for one channel and the stage monitor feed for the other channel.
BBE® applies different phase correction algorithms to three separate frequency bands. The variable front panel control
allows the user to adjust the amount of process desired.
Using Your New BBE 422A
BBE® is a process to be added before ail other mixing of reverb, special effects or equalization in order to increase the
clarity and intelligibility of the program material.
Unlike many aural exciters or equalizers, the BBE 422A does 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 to suit your own musical tastes.
Things To Remember
The BBE 422A is designed to work in -lOdBu levels. This is suitable for most semi-pro mixers, P.A. consoles, home
stereos or disco equipment. The BBE 422A drives load impedances down to about IK Ohms and supplies a maximum
level of +16dBu. Plugging a guitar or a microphone directly into the BBE 422A will not work, as the output level is much
too low. In this application, a BBE 411 can be used as it accepts low level devices.
If the program material has excessive background noise, the noise may be modulated with the program. In this case,
an equalizer or some type of noise reduction system should be inserted in front of the BBE 422A to roll off the noise first.
WARNING!
It is good practice to turn on any effects boxes such as BBE, equalizers, expanders, surround sound accessories,
etc., and the preamp BEFORE turning on the power amplifier. Otherwise damage to the speakers and/or amplifier
may result.
