1. INPUT: Use this jack to connect your
instrument to the amplifier by means of a
shielded instrument cable.
2. -15dB PAD: This switch, when depressed,
attenuates the input signal by 15dB.
Attenuation allows the Gain control (#4) to be
used over a larger portion of its range. If clip-
ping is indicated with the Gain control near
minimum, attenuation is needed.
3. PEAK: This LED illuminates when the
signal level into the preamp approaches
clipping. Adjust the Gain control (#4) until a
strong signal from your instrument causes
this LED to flash.
NOTE: If the LED flashes frequently with
the Gain at a low setting, use the -15dB
Pad (#2) to attenuate the input signal and
readjust the Gain.
4. GAIN: Use this control to adjust the input
signal level. For the best signal to noise
ratio, adjust this control until the Peak LED
(#3) flashes on strong signals.
5. BASS: This is the primary low frequency
control which allows for 13dB of boost or
15dB of cut at 40Hz.
6. ULTRA-MID: This is the primary
midrange control. Rotate the control to the
left of center for a “contoured” sound (more
distant, less midrange output) or to the
right of center for a pronounced (more up-
front) tone.
7. TREBLE: This is the primary high fre-
quency control which allows for 16dB of
boost or 21dB of cut at 8kHz.
8. MASTER: Set the overall output level of
the amplifier with this control. The Effects
Loop and Bal. Out (#20,21,24) are not
affected by the Master control.
9. LIMITER: The B2RE uses an internal
Optocoupler Limiter to assist in keeping the
power amplifier’s output “clean” at extreme
volume levels. (All amplifiers begin to clip
their output signals as they approach maxi-
mum output levels, resulting in distortion
which may damage your speakers.) To
engage the Limiter, depress the Limit
switch. Whenever the amplifier is at full
power, the adjacent Limit LED will flash.
This is an indication that the limiter is keep-
ing peak signals from clipping the output.
NOTE: Playing at full power with the Limiter
off will give you increased output power, but
the sound may be distorted. Use discretion
when playing without the Limiter.
10. EQ: Depress this switch to activate the
Graphic EQ. The adjacent On LED illumi-
nates when the EQ is on.
11. (NINE BAND GRAPHIC EQUALIZER):
These sliders control the output of the fre-
quencies indicated above each control.
The center position of each control is flat
(no boost or cut).
12. ON: This LED indicator illuminates
when the POWER switch (#13) is ON.
13. POWER: This heavy-duty rocker
switch applies the power to the amplifier.
The amp is ON when the top of the switch
is depressed, OFF when the bottom of the
switch is depressed.
