- The HI-CUT button is in the ON position although you are not running a biamped rig. Switch the HI-CUT off
(button not depressed).

Using the Stageboard, you are unable to turn off the VARIMETRIC EQ or the FX LOOP, or you can only
activate VARIMETRIC B:
- The EQ or FX LOOP front panel selector switches were inadvertently left in the ON position. Press the
appropriate selector switch to disengage front panel control.
- The STAGEBOARD is not plugged in. Connect it to the BassBase.
- The MIDI module was previously active. Briefly press the MIDI LEARN button to clear the MIDI mode.
E5)
The sound is thin and muddy when the FX processor is active.
- The signal processor is causing phase shifting that is being added to the original signal in the parallel loop.
Turn the FX-MIX control all the way to the right (WET) to avoid phase cancellations.
E6)
The red CLIP LED keeps illuminating.
- The BassBase 600's input is overloaded. Press the -10 dB button or turn your instrument's volume pot
down.
- The BassBase 600's preamp is overloaded. Reduce the GAIN.
- The BassBase 600's FX LOOP is overloaded. Briefly disconnect the FX processor from the loop. If the CLIP
LED no longer illuminates, you must reduce the processor's output level.
E7)
When using the LINE OUT or HF OUT jacks, you experience annoying hum.
- You have just encountered a ground loop (possibly coming from a mixing console or power amp) or
interference (possibly from emanating from a transformer or neon lighting). In the first situation, ensure the
connection is galvanically separated by routing the signal through a DI box. Important: never sever the
ground!
For the second problem, switch off the source of interference or reroute the connector cable.
NOTE: The BassBase 600's DI OUT is transformer-balanced, in other words, it features an integrated DI
box. This type of output ensures that a ground loop is highly unlikely. You also have a GROUND LIFT
switch available.
