Roland 210 User Manual

The following steps are effective in adjusting the tone when the D-BASS 210/115 and 115X are used together (stacked).

■ Setup

• Before connecting the 115X, make tone adjustments roughly on the 210/115 alone first.

• After connecting the 115X, start out with all of the unit's knobs set to the center position.

■ Selecting the Mode

• Select the desired 115X mode.

If it is a greater sense of volume that you want, select FULL RANGE.

If you are aiming for a tight, low sound, select SUB WOOFER.

■ Adjusting in FULL RANGE Mode

• You can adjust the volume balance of the 210/115 and the 115X using the 115X’s VOLUME knob.

• As you listen to the overall combined tone from the 210/115 and the 115X, adjust the TWEETER LEVEL knob.

Use a lower setting if there is excessive reverberation in the high end.

If you have trouble eliminating the muffled sound, use a higher setting.

■ Adjusting in SUB WOOFER Mode

• As you listen to the overall combined tone from the 210/115 and the 115X, adjust the tone with the VOLUME and 

FREQUENCY knobs.

Adjust the volume of the lower range with the VOLUME konb, and adjust the tone of the lower range with the FREQUENCY 
knob.

The aim of these adjustments is to achieve a smooth, continuous link in the low frequencies between the 210/115 and the 
115X.

Setups in which an acoustic bass is played through a bass amp can tend to cause 
feedback in the low-mid frequencies when the sound output from the speaker enters 
the f-hole in the bass body, resulting in a boomy reverberant sound. If this occurs 
when using a D-BASS stacked configuration, you can suppress low-mid 
reverberation by lowering the FREQUENCY setting in SUB WOOFER mode, thus 
making it difficult for feedback to occur.
