FRONT PANEL DESCRIPTION
1.
Input jack – Accepts a standard 6.25mm (1/4
”
) audio jack for connecting active or passive basses using a properly
shielded cable.
2.
Gain – Adjusts the input gain of the preamp stage.
3.
Signal Level LED – This LED, when green indicates that the input is at least 0dBU (0.77V RMS). When red, it
indicates clipping in the preamp stage. If the preamp is clipping, turn down the gain on some of the preamp stage
controls (Gain, EQ or Compression as applicable).
4.
Mute ON/OFF – Engaging this switch will mute all outputs except for the Tuner Out. When not engaged, the
respective channel is activated.
5.

Equalizer – 4-Band EQ pr/- 12 dB of gain for each band.
• BASS – 100Hz
• LOW MID – 800Hz
• HIGH MID – 3kHz
• TREBLE – 10kHz
7.
Compression Amount – This knob controls, as the name says, the amount of compression by providing simultaneous control
over compression threshold and make-up gain. The Compression knob, whenever engaged should be used in conjunction with
the Gain control. Settings of up to about 12 o
’
clock add a subtle compression. This setting will only compress the most
aggressive transients in your signal. Setting the knob at ar
ound 3 o
’
clock yields a heavy compression effect, with more
make-up gain. We designed our compressor to be completely transparent and to not color the signal in any way.
8.
Compressor LED – When green, this indicates that the compressor is engaged. When orange, it indicates that the
signal is getting compressed.
9.
Compression ON/OFF – This switch engages/bypasses the compressor circuit.
10.
Volume – This knob controls the master volume.
11.
Amp Clip LED – This LED indicates that the output from the power amp module is clipping. If the power amp is
clipping, turn down the master volume.
