Features

1,020 W power and 136 dB max. SPL and LF extension down to 32 Hz

pass type enclosure, the DXS18 is able to realize 136 dB maximum SPL, and an extended LF down to 32

Hz with exceptional clarity and minimal distortion.

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 DXS18 speakers, effectively reducing the SPL of bass directed towards the stage

while increasing the bass levels directed towards the audience.

Reliability

The DXS18 features advanced protection circuits in the speaker unit, amplifier unit, and power supply

that ensure optimum reliability and extended equipment life.

Durability

The DXS18’s sturdy plywood cabinet is covered with an extremely durable LINE-X finish that provides

Owner’s Manual

Input the output signal from a source, such as a mixer, to the INPUT jack of the DXS18, and input the out-

put signal from the OUTPUT jack of the DXS18 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 DXS18 and the cutoff frequency of the high pass filter of the full-range speaker. The same fre-

quency range output from the DXS18 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 DXS18,

set this to [HPF POST] to use the high pass filter in the DXS18.

The pole sockets of the DXS18 are compatible with commercially available speaker poles of 35 mm diame-

ter and M20 screws.

Installing optional wheels SPW-1 at the back of the DXS18 enables you to transport the unit easily. To

install the wheels, use the screws installed in the DXS18 unit, after removing them from the 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 printing date. Since Yamaha makes continuous

improvements to the product, this manual may not apply to the specifications of your particular product. To obtain the latest

manual, access the Yamaha website then download the manual file. Since specifications, equipment or separately sold

accessories may not be the same in every locale, please check with your Yamaha dealer.

w Feet cups

When stacking multiple DXS18 units, align the rubber feet of the upper

DXS18 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) enables

you keep the LED always off.

r Wheel mounting holes

Optional SPW-1 wheels can be installed to the holes. For details on

installing the wheels or special precautions you should take, please

refer to the relevant manual for the wheels.

t AC IN socket

Connect the supplied AC power cord here. First, connect the power

cord to the DXS18, then insert the power cord plug into the AC outlet.

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 out-

puts the mixed signals of L and R.

i OUTPUT jacks

These are balanced output XLR jacks for connecting full-range speak-

ers or additional DXS18 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 DXS18 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

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.

!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 DXS18 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 set-

ting may improve low-range response, depending on the type and loca-

tion 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.

SPL and LF extension down to 32 Hz Powered by a 1,020 W amplifier with an 18" woofer with a 4" voice coil and housed in a sturdy bandpass type enclosure, the DXS18 is able to realize 136 dB maximum SPL, and an extended LF down to 32 Hz with exceptional clarity and minimal distortion.
PAGE 2
Setup of Cardioid Mode PRECAUTIONS Three-unit, side-by-side placement 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.
