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

 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.

Owner’s Manual

• The DXS18 is mainly used for the explana-

tions in this manual.

• The illustrations as shown in this manual are

for instructional purposes only.

• The company names and product names used

in this manual are the trademarks or registered

trademarks of their respective companies.

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.

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.

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.

* If any specific problem should persist, please contact your Yamaha dealer.

* The contents of this manual apply to the latest specifications as of the publishing date.

w Feet cups

When stacking multiple DXS units, align the rubber feet of the upper

DXS unit to the feet cups of the lower.

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.

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 tempo-

rary drop in the power voltage may occur, possibly resulting in abnor-

mal 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.

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 speak-

ers 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 addi-

tional 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 out-

put level from the OUTPUT jacks is linked to the LEVEL control

(!1), the levels of this unit and the full-range speaker change simulta-

neously.

!0 PEAK indicator

Lights red when the input level reaches 3 dB below clipping. If the indi-

cator 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 out-

put 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 OUT-

PUT 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.

!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 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.
