Properly Adjusting Input Gain
If using an active bass, start in Hi Output mode (Factory default setting), and with the input
gain fully off, play your bass like you normally would, including hard dynamic attacks.
Gradually turn the input gain up until you can see the OL led flash on the front panel of the
B|AMP. Once the OL led flashes, back off the knob 1/8 of a turn for additional headroom
before clipping. This is the optimal input level for your bass and playing style. Keep the
Instrument Level in Hi Output mode for this instrument.
If you can’t get the OL led to flash when the input gain is turned all the way up, that’s ok.
Leave the input gain turned all the way up and select Lo Output for Instrument Level and re-
adjust Master volume accordingly.
If using a passive instrument, start in Hi Output mode also and follow procedure described
above. If the OL led flashes under your normal playing conditions, stay in Hi Output mode. If
not, select Lo Output for Instrument Level, keeping the Input gain turned all the way up.
ð
For best S/N ration, when Lo Output mode is necessary, the instrument gain should
be turned all the way up.
ð
If the OL indicator flashes before reaching 9:00 on the Input gain knob, turn the
volume down on your bass, or, if your bass has a gain adjustment on its onboard
preamp, turn that gain down instead. Failure to do so could allow the input stage of the
B
|
AMP to be overdriven, limiting the dynamic range of your signal and creating
unnecessary distortion. In addition, if the output of your active bass is too hot, you
could unnecessarily and unknowingly be clipping your onboard preamp, introducing a
distorted signal to your amplification system right out of the gate! Try to adjust your
bass’ active output level to be the same as its passive level to ensure maximum
dynamic range and headroom before clipping. Remember, if your overall gain is set
too high, boosting any of your tone controls could easily clip your overall signal at the
output of your onboard preamp!
