When Using D-BASS 210/115 & 115X in Stack Configuration

Adjusting the Tone
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.
* Since the FREQUENCY knob also affects the overall low-frequency volume, we recommend that you readjust the VOLUME knob each
time you make an adjustment with the FREQUENCY knob. In general, you can make adjustment easier by turning up the VOLUME
knob slightly when you turn down the FREQUENCY knob setting, and turning down the VOLUME knob slightly when you turn up the
FREQUENCY knob setting.
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.
