- Before connecting the device to other devices, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum.

Handling caution

• When turning on the AC power in your audio system, always turn on the device LAST, to avoid speaker damage. When turning the power off, the device should be turned off FIRST for the same reason.
• 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 several hours without turning on the power until the condensation has completely dried out.
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any gaps or openings on the device. If this happens, turn off the power immediately and unplug the power cord from the AC outlet. Then have the device inspected by qualified Yamaha service personnel.
• 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.
• Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire.
• Do not rest your weight on the device or place heavy objects on it, and avoid use excessive force on the buttons, switches or connectors.
• Do not pull on any attached cable, such that of a microphone. Doing so may cause the speaker to topple, and result in damage or in injury.

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

Interference From Cell Phones

Using a cell phone near the speaker system can induce noise. If this occurs, move the cell phone further away from the speaker system.

Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.

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

The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualified Yamaha service personnel about replacing defective components.

DSR118W

■ 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 frequency 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 human 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 compact body in the class.

■ Powerful protection function

Separate advanced protection circuits in the speaker unit, amplifier unit, and power supply unit ensure optimum reliability and long equipment life.

Included Accessories

• AC power cord
• Owner's manual (this book)

Rear panel

INPUT PARALLEL THRU ① ② ③ PEAK LEVEL LINE+4dBu MIC YAMAHA POWERED SPEAKER MODEL DSR115 LIMIT PROTECTION POWER FRONT LED DISABLE HPF D-CONTOUR FLRX tuning

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 simultaneously. Please connect to only one of these jacks.

② THRU jack(s)

These are balanced XLR output jack(s). Input signals will be passed through unaffected, since these are parallel connected to the INPUT jacks.

③ 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.

4 LEVEL control

Adjusts the overall output level. Set the MIC/LINE switch (5) of the DSR112, DSR115 and DSR215 to LINE when connecting 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.

5 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 microphones), set the switch to the MIC (■) position. For high-level signals (such as electronic musical instruments and audio equipment), set the switch to the LINE (■) position.

⑥ 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 location of the speaker system. Try both settings and select the one that produces the best low-end sound.

⑦ LIMIT indicator

Lights when the output limiter is active. The output limiter will operate in the following situations, attenuating the output signals 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 consumption 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 consumption is detected, the LIMIT indicator will light when the amount of attenuation is 3dB or higher.

8 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 detected, 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 device down to prevent noise.

9 POWER indicator

Lights when the power switch (14) is set to on.

10 FRONT LED DISABLE switch

Selects turning on or off the LED at the lower left of the unit's front grill. The LED will light when this switch is set to off (■). Turn this switch on (■) when you want to turn off the LED.

NOTE

(DSR112/DSR115/DSR215) When the limiter for protecting the amplifier operates, the LED will light brighter than usual in proportion to the amount of attenuation (6dB or higher).

11 HPF switch (DSR112/DSR115/DSR215)

Toggles the HPF on or off. Press this switch to turn the HPF on (■), and the switch will light. When the switch is turned on, the high-pass filter cuts frequencies below 120Hz. We recommend that you turn this switch on if you connect the speaker directly to a microphone or use the speaker with a subwoofer.

⑫ D-CONTOUR switch (DSR112/DSR115/DSR215)

Toggles the D-CONTOUR (Dynamic CONTOUR) on or off. Press this switch to turn the D-CONTOUR on (■), and the switch will light. Turn this switch on if you want to emphasize the rhythm sound when playing dance music, etc., for example (page 6).
