Controls and functions

Features

 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 avail­able for improved portability.

Basic Setup

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 fre­quency 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.

CAUTION

If multiple powered speakers are connected in daisy-chain fashion, turn each device on
in sequence starting from the one nearest to the sound source, and turn them off start­ing from the one farthest from the sound source.

Installing a Speaker Pole

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 follow­ing conditions are met.

Subwoofer Top-mounted speaker Pole length

DXS18 Weight 28.0 kg or less, height 76 cm or less (DSR115) 120 cm or less
DXS15mkII Weight 19.3 kg or less, height 61 cm or less (DXR12) 100 cm or less

DXS12mkII

Weight 14.6 kg or less, height 51 cm or less (DXR10) 82 cm or less
Weight 13.5 kg or less, height 46 cm or less (DXR8) 90 cm or less

Installing Wheels

Installing optional wheels SPW-1 at the back of the DXS enables you to transport the unit easily. To install
the wheels, use the screws already installed in the DXS unit.
Please do not use the speaker once the screws are removed. This causes air leaks to occur in enclosure,
resulting in undesirable performance.

CAUTION

• For details on installing the wheels or special precautions you should take, please
refer to the relevant manual for the wheels.

• Do not install wheels other than the SPW-1.

q Pole sockets

Adapts to commercially available speaker poles of 35 mm diameter and
M20 screws. For details on installing speaker poles, refer to “Installing
a Speaker Pole.”

w Feet cups

When stacking multiple DXS units, align the rubber feet of the upper
DXS unit to the feet cups of the lower.

CAUTION

Do not stack more than two DXS units.

e Front LED

Turns on when the power is on. Lights more brightly when the output
limiter is active. Using FRONT LED DISABLE switch (!9) allows you
to defeat the front LED altogether.

r Wheel mounting holes

Optional SPW-1 wheels can be installed at these locations. For details
on installing the wheels or special precautions you should take, please
refer to the relevant manual for the wheels.

t AC IN inlet (V-Lock)

Connect the AC power cord included with the unit. The AC power cord
includes a locking mechanism with a latch. First connect the DXS to the
AC power cord, and then connect the power cord to the AC outlet.
When removing the cord, push the latch while pulling the cord out.

CAUTION

Turn off the power before you connect or discon-

y Power switch

Turns the power to the unit on ( ) or off ( ).
If you are using multiple units, turn on the power to each unit one by
one. If you turn on the power to multiple units simultaneously, a tempo­rary drop in the power voltage may occur, possibly resulting in abnor­mal operation of the units.
Also, rapidly turning the unit on and off in succession can cause it to
malfunction. After turning the unit off, wait for about 5 seconds before
turning it on again.

nect the power cord.

CAUTION

A slight electrical current will flow even when the
power switch is turned off. Make sure to unplug
the power cord from the power outlet when not
using the speaker for an extended period of time.

u INPUT jacks

These are balanced input XLR jacks (line-level), and this device outputs
the mixed signals of L and R.

i OUTPUT jacks

These are balanced output XLR jacks for connecting full-range speak­ers or additional DXS units. The output signal can be switched via the
THROUGH/HPF POST switch (o).
L/R output from the OUTPUT jacks correspond to L/R input to the
INPUT jacks. The mixed signal of L/R is not output.

o THROUGH/HPF POST switch

Switches the signals output from the OUTPUT jacks (i).

• THROUGH: Outputs unaffected signals from INPUT jacks (u).

Select when using HPF of the connected speaker or connecting addi­tional DXS units.

• HPF POST: Outputs signal input from INPUT jacks (u) after pass-

ing through a HPF. The cutoff frequency of the high pass filter is the
frequency specified with the X-OVER switch (!2). Because the out­put level from the OUTPUT jacks is linked to the LEVEL control
(!1), the levels of this unit and the full-range speaker change simulta­neously.

!0 PEAK indicator

Lights red when the input level reaches 3 dB below clipping. If the indi­cator lights frequently, adjust the volume of the input source or lower
the LEVEL control (!1) so that the indicator flashes only briefly at the
highest input levels.

!1 LEVEL control

Adjusts the output level.

!2 X-OVER switch

Specifies the crossover frequency at 120 Hz, 100 Hz, or 80 Hz. The out­put from the unit is processed through a low pass filter to cut the range
of the selected frequency or higher. When setting THROUGH/HPF
POST switch (o) to [HPF POST], the output signals from the OUT­PUT jacks are processed through a high pass filter to cut the range of
the selected frequency or lower, and the crossover frequency is linked to
that of the connected speaker.

CAUTION

Make sure to lower the input level when switching.

!3 D-XSUB switch

Switches the low-range frequency response characteristics.

• NORMAL: A generic setting corresponding to various applications.

• BOOST: Boosts the frequency range enhancing and providing punch

to the sound.

• XTD LF (eXTenDed LF): Extends the bottom of the low frequency

range.

!4 CARDIOID switch

Connection of multiple DXS units enables the use of Cardioid mode.
For details on Cardioid mode and using the switch, refer to “Setup of
Cardioid Mode” on the opposite page.

!5 POLARITY switch

Switches the polarity of the unit, normal or inverted. When the polarity
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 sec­onds. The indicator turns off when the power supply has started nor­mally.)

!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.

Directional characteristics

Because directivity in the low frequency range is weak, the output sound from the subwoofer diffracts not
only toward the audience but also to the stage in almost the same sound pressure. By using the Cardioid
mode, bass to the audience is summed up and bass to the stage is canceled. This suppresses the bass volume
on the stage, providing a greater allowance before howling, and provides more powerful bass for the audi­ence.

NOTE

• Use the same model and input signal for the DXS. You can also use the units connected in daisy chain
fashion with setting the OUTPUT jack to [THROUGH].

• To obtain the optimum Cardioid characteristics, locate the cabinet away from walls by more than 1.2 m.

Two-unit, side-by-side placement

Place the two DXS units facing in opposite directions. Set the CARDIOID switch of the DXS facing the
audience to off, and that of the DXS facing the stage to on. Make sure that the other settings (LEVEL,
POLARITY, X-OVER) of the units are set the same.

Two-unit, vertically stacked placement

You can also construct a system for Cardioid mode by vertically stacking two units. Set the CARDIOID
switch of the DXS facing to the stage side to on. Make sure that the other settings (LEVEL, POLARITY, X­OVER) of the units are set the same.

CAUTION

• When vertically stacking DXS units, make sure they are stable and not in danger of
falling over.

• Align the rubber feet of the upper DXS unit to the feet cups of the lower DXS.

• When using vertically stacked DXS units, do not place any objects (such as full-range
speakers or another DXS) on top of them or insert speaker poles.

2

Three-unit, side-by-side placement

Set the CARDIOID switch of only the DXS unit facing the stage to on. Set the levels of the two DXS units
facing the audience to the same. Set the level of the DXS unit facing to the stage approximately 6 dB greater
than the DXS units facing the audience.

About Cardioid mode

The distance between a speaker (A) facing to the audience sound source speaker and another speaker (B)
facing to the stage is defined as d. A delay is applied to the sound from speaker B, equivalent to distance d.

The sound of each speaker is cancelled on the stage
side and summed together on the audience side. The
directional characteristics of this combination are
represented in the polar pattern illustration at right.
Since the form resembles a heart shape, it is called
Cardioid mode.
