6. VOLUME Knob
This adjusts the total volume level of the unit’s internal
speaker.
When connecting the D-BASS 210/115 SUB OUT jack to
the 115X’s INPUT jack, adjust the volume balance
between the 115X and the D-BASS 210/115 speaker
output.
* Does not affect THRU OUT.
7. POWER Switch
This switches the power on and off.
* If you need to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from the power
outlet. Refer to “Power Supply” (p. 7).
* Once the connections have been completed, turn on power to
your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction and/
or damage to speakers and other devices.
1. Turn on the device connected to the D-BASS 115X’s
input jack.
2. Turn on the D-BASS 115X.
3. Switch on any equipment connected to the D-BASS
115X’s SUB OUT jack.
Turn off the devices in the reverse order to which they
were switched on.
* This unit is equipped with a protection circuit. A brief interval
(a few seconds) after power up is required before the unit will
operate normally.
* Always make sure to have the volume level turned down before
switching on power. Even with the volume all the way down,
you may still hear some sound when the power is switched on,
but this is normal, and does not indicate a malfunction.
