General Operation
In order to reduce the risk of damage to any equipment, properly connect all audio and power cables
before turning on any components in the system. Most important of all, ALWAYS TURN ON THE POWER
AMPLIFIER LAST TO AVOID DAMAGING THE SPEAKERS OR THE AMP.
The Bass and T
reble controls are mainly "boost" and the Mid control only "cut". While there is no absolutely
flat position, the response is reasonably flat with the controls set at TREBLE:2, MID:10, BASS: 2, with the
bright switch off. The circuit can be described as interacting, such that the frequencies affected by each
control is affected somewhat by the settings of the others.When all 3 tone controls are turned to 0 then
no signal is passed at all.
BBE’s exclusive "PARA-MID" midrange equalization offers even further control over the crucial mid-band
of the Bass’ overall tonal characteristics.
Compression is a feature that will be welcomed by any bass player. Adjust the LEVEL knob to eliminate
any volume peaks. An increase in sustain is also a desired result of large amounts of compression as deter
-
mined by the LEVEL control.
The BBE Process is a unique feature that only the BBE series of pre-amps possess. The BBE Process will pro-
duce a clear, crisp, full-bodied sound without adding any noise or harmonic distortion to the signal. The
BBE Process should be used as an extension of the Equalization controls to improve the overall quality of
the bass guitar's tone.
The Volume control will simultaneously adjust the BMAX's output volume from both outputs: The Bal-
anced and Unbalanced outputs. Use either the Unbalanced or the Balanced output to connect to a power
amp or a mixing console. The Unbalanced outputs are 1/4" monaural phone plugs while the Balanced
output is a male XLR connector with a Ground Lift switch to eliminate any multiple ground connections.
