HOW THE BBE PROCESS WORKS
The BBE Process has been designed to make music programs more intelligible and life-like
than normally achieved with existing audio systems. The BBE Process works dynamically
by boosting the harmonic content of the music program, as determined by the signal input,
and imparting a linear phase shift across the audio spectrum. The phase shift allows for a
separation of the high, mid and low frequencies so that they do not arrive at the speaker
network at precisely the same time. This prevents the higher frequencies from being
smothered. (As the phase shift is minimal, 2 milliseconds, it is not perceived as a delay or
echo.) The amount of harmonic amplification is variable as selected by the PROCESS
knob, to achieve crisp, tight music program. The LO CONTOUR knob is a bass frequency
adjustment. When turned clockwise, the LO CONTOUR will add power and warmth to the
music program. If your musical tastes require the bass frequencies be reduced, turn the
knob counter-clockwise.
Although the majority of the process is achieved with the higher frequencies of the music
program, the BBE Process will make a significant difference with the entire program. For
example: An "A" at 440Hz on a guitar is fundamentally the same note as an "A" at 440Hz
on a piano. What allows a listener to identify the respective instruments is the harmonic
content. By realigning the phase relationship and amplitude of the harmonic frequencies,
the distinctive sound of a guitar, a piano, or any musical instrument, is much more evident.
FRONT PANEL CONTROLS AND CONNECTIONS
NOTE: BOTH CHANNELS OF THE BBE 862 ARE INDEPENDENT FROM EACH OTHER
AND MAY PROCESS A STEREO SIGNAL SOURCE OR TWO INDEPENDENT SIGNAL
SOURCES. NO DAMAGE WILL BE INFLICTED TO THE BBE 862 IF ONLY ONE
CHANNEL IS UTILIZED.
CHANNEL A
1. LED DISPLAY: The LED display is used to indicate the output signal level of
the BBE 862. Each number on the front panel corresponds to the output signal
level, measured in decibels. Example: The "+10" indicates a lOdBu signal level,
"0" refers to OdBu, and so on. Once an input signal level has been established,
increasing the BBE PROCESS and LO CONTOUR, will increase the output
