Main Features

•Sophisticated DSP processing

Our proprietary sound-processing technology, called FIR-X Tuning, utilizes a linear-phase FIR filter—delivering excellent sound quality with high resolution and a smooth frequency response that is unaffected by phase interference near the crossover point.

•Easy sound optimization

D-CONTOUR (Dynamic CONTOUR) constantly monitors the output of multiple frequency bands, and applies the optimum EQ adjustments to each according to the listener’s preferences. There are two modes: an FOH/MAIN mode for use as a main speaker, and a MONITOR mode for use as a floor monitor, letting you select the preset tuning optimized for each application.

•Various input/output connectors and convenient, simple mixing function

The comprehensive set of connectors—including XLR for a mixer, phone for a musical instrument, and RCA pin for an audio player—provides maximum flexibility in use with a wide variety of applications. Also, the DHR features simple mixing functionality, enabling you to select either a direct output of channel 1 (CH1) (parallel connection) or a mixed output of CH1 and CH2, for convenient system setup.

•Lineup for a variety of applications

The models are optimized for various applications: the DHR15 is ideal for use as a main speaker delivering powerful sound and the DHR12M with its sound character optimized for monitoring is ideal for use as a compact floor monitor. The rotatable horn equipped DHR10 is ideal for use as a fixed installation, and can be installed vertically or horizontally with optional brackets.

•High-grade and durable wood cabinet for superior sound

The naturally textured wood cabinet of the DHR features a durable coating with high damage resistance to protect the cabinet from scratches and bumps during transport, installations and removal.

y[LIMIT] indicator

Indicates (lit in red) that the limiter is on when the output voltage of the amplifier has exceeded the maximum level, or when excessive integral power consumption is detected. If this indicator stays lit, lower the input level.

NOTE

Integral power consumption refers to the sum of power provided to the speaker driver per unit time.

u[SIGNAL] indicator

Indicates (lit in green) when an audio signal exceeding the threshold has been detected.

i[PROTECTION] indicator

Indicates (lit in red) when the protection circuit is active. The protection circuit will be activated and the speaker outputs will be muted in the situations listed below.

•If amplifier overheating is detected

•If overcurrent is detected

•When turning the power on; the protection circuit will be activated for a few seconds to prevent noise. The indicator turns off when the power supply has started normally.

If the protection circuit has engaged, 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.

Selects one of the D-CONTOUR (Dynamic CONTOUR) presets.

[FOH/MAIN]: Boosts the high and low frequency components so that the frequency response is suitable for a main speaker.

[MONITOR]: Reduces the low frequency range, which could otherwise tend to be boomy if the speaker is set directly on the floor. This enables you to hear mid and high frequency ranges clearly when using as a floor monitor.

[OFF]: Turns off D-CONTOUR. This is a generic frequency response setting.

!2[HPF] switch

Selects the cutoff frequency of the high pass filter. If you set this switch to [120Hz] or [100Hz], the low frequency components below each threshold will be cut. If you use the unit alone, set this switch to [OFF]. If you plan to use the unit along with a subwoofer, we recommend that you set this switch to [120Hz] or [100Hz].
