Main Features of the DSR Series

■ Speaker processing functionality

provided by internal DSP

(DSR112/DSR115/DSR215)

The internal DSP delivers high-resolution sound by using

speaker processing functionality that has been optimized for

each model of the DSR series.

■ FIR-X tuning™ feature

(DSR112/DSR115/DSR215)

Linear phase FIR filter provides natural sound quality and

smooth frequency response without phase cancellation

around the crossover point.

■ D-CONTOUR (Dynamic CONTOUR)

feature (DSR112/DSR115/DSR215)

D-CONTOUR is a newly developed three-band multiband

compressor. It dynamically adjusts the level of each fre-

quency range according to the volume of speaker outputs. It

boosts the high and low frequencies when the volume level is

low, and it reduces the amount of boost when the volume

level is high. So that it delivers powerful sound tailored to hu-

man hearing. For example, this is useful for dance music,

etc., if you want to emphasize the rhythm.

■ Light and compact

Featuring class-D amplifier, switching power supply with

PFC, and light powerful magnetic neodymium magnet

(DSR112 and DSR115 only) provides top-level light and com-

pact body in the class.

■ Powerful protection function

Separate advanced protection circuits in the speaker unit,

amplifier unit, and power supply unit ensure optimum reliabil-

ity and long equipment life.

Controls and Functions

Rear panel

INPUT jacks

These are balanced XLR and phone input jacks.

The DSR118W has XLR jacks (L, R) only.

NOTE

You may use either the XLR or the phone jack, but not both types si-

multaneously. Please connect to only one of these jacks.

THRU jack(s)

These are balanced XLR output jack(s). Input signals will be

passed through unaffected, since these are parallel con-

nected to the INPUT jacks.

PEAK Indicator

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

If the PEAK indicator frequently lights, adjust the volume of

the input source so that the PEAK indicator flashes briefly on

the highest input levels.

LEVEL control

Adjusts the overall output level. Set the MIC/LINE switch ()

of the DSR112, DSR115 and DSR215 to LINE when connect-

ing a device (such as a mixer) whose specified output level

is +4dBu. In this condition, set the LEVEL control to roughly a

12:00 position to obtain sufficient output.

MIC/LINE switch (DSR112/DSR115/DSR215)

Set this switch to MIC or LINE for INPUT jacks, depending on

the level of the input signal. For low-level signals (such as mi-

crophones), set the switch to the MIC ( ) position. For high-

level signals (such as electronic musical instruments and au-

dio equipment), set the switch to the LINE () position.

POLARITY switch (DSR118W)

Selects the subwoofer polarity. You will usually set this switch

to NORMAL (). However, an INVERTED ( ) setting may

improve low-range response, depending on the type and lo-

cation of the speaker system. Try both settings and select the

one that produces the best low-end sound.

LIMIT indicator

Lights when the output limiter is active. The output limiter will

operate in the following situations, attenuating the output sig-

nals to the amplifier.

•If the output voltage of the amplifier has exceeded the

maximum value

•If excessive integral power consumption is detected

•If the amplifier overheats

NOTE

• The integral power consumption refers to the sum of power con-

sumption provided to the speaker driver per unit time.

• (DSR112/DSR115/DSR215) If the output voltage of the amplifier has

exceeded the maximum value, or if excessive integral power con-

sumption is detected, the LIMIT indicator will light when the amount

of attenuation is 3dB or higher.

PROTECTION indicator

Lights when the protection system is active. The protection

system will operate in the following situations.

NOTE

If the protection system has engaged after the problem was de-

tected, waiting until the amplifier cools down or powering off and on

again will return to normal operation. If the unit does not return to

normal operation, please contact your Yamaha dealer.

•If amplifier overheating is detected:

The speaker output will be muted.

•If DC output is detected:

After the indicator lights, the speaker output will be muted,

and the power supply section will be shut down.

•If overcurrent is detected:

The speaker output will be muted.

•When turning the power on:

Lights for about two seconds when the power supply starts.

The indicator turns off when the power supply has started

normally.

•When turning the power off:

If the power switch is set to off, or if the power turns off by

an unexpected error, the protection system will shut the de-

vice down to prevent noise.
