Troubleshooting

Sounds not output

Is the mute function switched on?

If you have a foot switch connected, set both the foot switch and the front panel MUTE switch to OFF.

Is the power to the external effects processor turned off or the effect volume turned completely down?

With an external effects processor connected, and using a series connection, only the effect sound is output (p. 12). Check the 
external effects processor’s output level.

D-BASS 115X TWEETER LEVEL knob has no effect

Is the TWEETER knob on the D-BASS 210/115 connected to the INPUT jack turned completely down?

When the TWEETER knob on the D-BASS 210/115 is turned down all the way, the signals in the tweeter’s frequency range 
are not output from SUB OUT, diminishing the effect of the 115X’s TWEETER knob.
