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.
