THE CONTROLS
1) LOEQ
Each channel has a LO EQ control that regulates the amount of
phase compensated bass equalization. This adjustment ranges from
-lOdBu fully counterclockwise to +11dBu fully clockwise at SOHz
relative to the input. In the middle position, there is a +3dBu boost.
2) PROCESS CONTROL
Each channel has a process control that, when minimum, switches
the unit into bypass mode. A slight turn clockwise will switch the BBE
702 into process mode, illuminating the "on" LED, where the high
frequencies are slightly attenuated. As the knob is turned clockwise,
it will increase the amount of amplitude compensation to the program
up to +6dBu.
3) LED STACK
Each channel is equipped with a set of LED indicators that instantly
show the relative amount of high frequency compensation as
compared to the mid band.
RED LED:
Marked
The amplitude of the high band
is too high as compared to the mid-band and is being compressed.
AMBER LED:
Marked "0": No amplitude compensation is needed.
The program spectral content is correct.
GREEN LED:
Marked
The amplitude of the high band is to low
as compared to the mid band and is being expanded to compensate.
CLIP LED:
This LED indicates that the input of the BBE 702 has
reached the maximum level of +20dBu (The clip LED lights +3dBu
prior to true clip on the BBE 702).
4) IN/AUTO SWITCH:
In the "in" position, the BBE 702 provides dynamic response to
the high frequency band in relation to the mid band. This in turn will
allow the BBE process to either expand or compress the high band.
The "out" position, on the other hand, provides for a factory
preset expansion ratio for the high band. This mode of operation can
also be used for program with a wide dynamic range so that it will
