Introduction
Thank you very much for purchasing the DXS Powered Subwoofer. The DXS is a powered subwoofer used
for sound reinforcement and temporary installations. This owner's manual explains how to set up and use
the subwoofer in live venues and temporary PA installations to enhance low-end sound. Be sure to read this
manual before using this subwoofer, in order to make sufficient use of the many functions that this product
offers. Also, be sure to keep this manual after you are finished reading it.

Features
EN
High power, high sound pressure, superior low-end playback capabilities
Adopting a bandpass type enclusure for high sound pressure. The DXS features a high-resistance input,
low distortion woofer and a 1,020 W power amplifier to achieve superior low-end playback capability
and high sound pressure.
Flexible features
• D-XSUB: D-XSUB is a DSP technology that gives users additional dynamic control of the frequency
range to meet the demands of a variety of applications or musical styles.
• Selectable X-OVER (80/100/120 Hz): Selecting the cut-off frequency and LPF/HPF settings offers
users more flexibility to adapt to various applications.
• Cardioid mode: The Cardioid mode setting adds additional control of low frequencies for sub-woofer
arrays of two or more DXS speakers, effectively reducing the SPL of bass directed towards the stage
while increasing the bass levels directed towards the audience.
Reliability
A high-performance DSP control protects the speaker and amplifier. The DXS can be used worry-free,
even under harsh operating conditions.
Durability
The DXS's sturdy plywood cabinet is covered with an extremely durable polyurea finish that provides
added protection from outside elements.
Fast and easy setup
M20 and Ø35 mm dual pole sockets allow for more flexible set up, while optional casters are also avail-
able for improved portability.

to the sound.
• XTD LF (eXTenDed LF): Extends the bottom of the low frequency
range.

Connection of multiple DXS units enables the use of Cardioid mode.

is inverted, the INVRT indicator lights.
In most cases, this should be set to normal; however, the inverted setting
may improve low-range response, depending on the type and location of
the speaker system. Select a setting that produces the best low-end
sound.
!6 LIMIT indicator
Lights when the output limiter is active. The output limiter operates in
order to protect the speaker and amplifier, attenuating the output signal
to the amplifier. If the indicator lights frequently, adjust the volume of
the input source or lower the LEVEL control (!1 ) so that the indicator
only occasionally lights at the highest input levels.
!7 PROTECTION indicator
Lights when the protection system is active. The protection system
operates and the speaker output is muted in the following situations.
• If amplifier overheating is detected.
• If overcurrent is detected.
• Immediately after turning the power on. (The protection system is
activated to prevent noise and the indicator lights for about two sec-
onds. The indicator turns off when the power supply has started nor-
mally.)
!8 POWER indicator
Lights when the power is on.
!9 FRONT LED DISABLE switch
Turns the FRONT LED at the front of the unit on or off. The LED lights
when this switch is set to off. Turn this switch on to disable the LED.
Input the output signal from a source, such as a mixer, to the INPUT jack of the DXS, and input the output
signal from the OUTPUT jack of the DXS to the input jack of a full-range speaker.
• X-OVER switch (!2 )
It is recommended that you match the crossover frequency (the cutoff frequency of the low pass filter)
of the DXS and the cutoff frequency of the high pass filter of the full-range speaker. The same fre-
quency range output from the DXS and the full-range speaker may cause interference with each other
and degrade the frequency characteristics.
• THROUGH/HPF POST switch (o)
If the full-range speaker is properly equipped with a high pass filter, you should set this to
[THROUGH]. The [THROUGH] setting enables you to control the level independently and minimize
signal delay. If the full-range speaker is not equipped with a high pass filter or the high pass filter in the
full-range speaker cannot be set to the same cutoff frequency as that of the low pass filter of the DXS,
set this to [HPF POST] to use the high pass filter in the DXS.

Basic Setup
This is a pole socket used to mount a full-range speaker atop the DXS. The pole socket is compatible with
35 mm or M20 speaker poles, available commercially. When using the pole socket, be sure that the follow-
ing conditions are met.
