BBE Sonic Maximizer BBE 422 - Manual (Page 4)

Product Description
The BBE 422 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 -tOdBu unbalanced line level applications such as those found in semi-
professional and musical instrument applications. The BBE 422 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 a house PA. 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. A variable front panel control for
each channel allows the user to adjust the amount of process desired.
Using Your New BBE 422
BBE'" is a process to be added before all other mixing of reverb, special effects or equalization. The BBE 422 is used to
increase the clarity and intelligibility of the program material.
Unlike many aural exciters or equalizers, the BBE 422 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.
Things To Remember
The BBE 422 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 422 drives load impedances down to about IK Ohm and supplies a maximum level of -M4dBu.
The inputs and outputs are unbalanced types and input to the BBE 422 should be kept at maximum level. Plugging a guitar or
a microphone directly into the BBE 422 will not work, as the output level is much too low. In this application a BBE 401 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 422 to roll off the noise first. Post­
amplification of the BBE 422 is not necessary and not recommended, as the BBE 422 can drive any semi-pro gear with
-lOdBu input to full level directly. This assumes that the BBE 422 is operating in the aforementioned fashion with -lOdBu
input levels.
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 may result.
