Setup of Cardioid Mode

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 audi-

ence.

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.

You can also construct a system for Cardioid mode by vertically stacking two units. Set the CARDIOID

OVER) 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.

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.

PRECAUTIONS

PLEASE READ CAREFULLY BEFORE

PROCEEDING

Please keep this manual in a safe place for future

reference.

WARNING

Always follow the basic precautions listed below

to avoid the possibility of serious injury or even

death from electrical shock, short-circuiting,

damages, fire or other hazards. These precautions

include, but are not limited to, the following:

Power supply/power cord

• Do not place the power cord near heat sources such as

Off

heaters or radiators, and do not excessively bend or

otherwise damage the cord, place heavy objects on it, or

place it in a position where anyone could walk on, trip

over, or roll anything over it.

• Only use the voltage specified as correct for the device.

The required voltage is printed on the name plate of the

device.

• Use only the supplied power cord/plug.

If you intend to use the device in an area other than in the

Stage

one you purchased, the included power cord may not be

compatible. Please check with your Yamaha dealer.

• Check the electric plug periodically and remove any dirt

or dust which may have accumulated on it.

• When setting up the device, make sure that the AC outlet

you are using is easily accessible. If some trouble or

malfunction occurs, immediately turn off the power switch

and disconnect the plug from the outlet. Even when the

power switch is turned off, as long as the power cord is

not unplugged from the wall AC outlet, the device will not

be disconnected from the power source.

•

Remove the electric plug from the outlet when the

device is not to be used for extended periods of time, or

during electrical storms.

•

Be sure to connect to an appropriate outlet with a

protective grounding connection. Improper grounding

can result in electrical shock, fire, or damage.

Do not open

• This device contains no user-serviceable parts. Do not

open the device or attempt to disassemble the internal

parts or modify them in any way. If it should appear to be

malfunctioning, discontinue use immediately and have it

inspected by qualified Yamaha service personnel.

Water warning

• Do not expose the device to rain, use it near water or in

damp or wet conditions, or place on it any containers

(such as vases, bottles or glasses) containing liquids

which might spill into any openings. If any liquid such as

water seeps into the device, turn off the power

immediately and unplug the power cord from the AC

outlet. Then have the device inspected by qualified

Yamaha service personnel.

• Never insert or remove an electric plug with wet hands.

Hearing loss

• Do not use the device for a long period of time at a high or

uncomfortable volume level, since this can cause

permanent hearing loss. If you experience any hearing

loss or ringing in the ears, consult a physician.

• Before connecting the device to other devices, turn off the

power for all devices. Also, before turning the power of all

devices on or off, make sure that all volume levels are set

to the minimum. Failing to do so may result in hearing

loss, electric shock, or device damage.

• When turning on the AC power in your audio system,

should be turned off FIRST for the same reason.

Fire warning

• Do not place any burning items or open flames near the

device, since they may cause a fire.

If you notice any abnormality

• If any of the following problems occur, immediately turn

off the power switch and disconnect the electric plug from

the outlet.

- The power cord or plug becomes frayed or damaged.

To avoid the possibility of malfunction/damage to the product, or damage to other property, follow the notices below.

 Handling and maintenance

• Do not use the device in the vicinity of a TV, radio, AV equipment, mobile phone, or other electric devices. Otherwise, the

device, TV, or radio may generate noise.

• Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater,

or in a car during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the

internal components.

• Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel.

• When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-

impregnated wiping cloths.

• Condensation can occur in the device due to rapid, drastic changes in ambient temperature—when the device is moved

from one location to another, or air conditioning is turned on or off, for example. Using the device while condensation is

present can cause damage. If there is reason to believe that condensation might have occurred, leave the device for sev-

eral hours without turning on the power until the condensation has completely dried out.

• When placing the speaker face down, always place it on a flat surface.

• Do not touch the speaker driver unit.

Audience side

• Air blowing out of the ports is normal.

• Always turn the power off when the device is not in use.

 Connectors

• XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (–).
