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 cross-
over 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 function-
ality, 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 brack-
ets.
• 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.

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.
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 indi-
cator turns off when the power supply has started nor-
mally.
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.

Setup Examples
Fixed installations—using the DHR10
DHR10 can be neatly installed on a ceiling or a wall, either horizontally or vertically, with the separately sold Yamaha UB-
DXRDHR10 U-bracket. For instructions on installing the U-bracket, refer to the corresponding manual for the UB-DXRDHR10.
Also, the DHR10 features a rotatable horn (90 degrees). When shipped from the factory, the directivity of DHR10 in a vertical ori-
entation is the setting which makes the sound expand in a horizontal direction, and inhibits or narrows the sound in a vertical
direction. We recommend changing the directivity by rotating the horn when you want to install the DHR10 horizontally and
broaden the directivity.
The UB-DXRDHR10 can be used together with separately sold optional brackets, such as the Yamaha BBS251 Baton Bracket.
NOTE

Installation Examples
Suspended Installation Using Eye Bolts (DHR15 and DHR10 only)
Attach commercially available long eye bolts (30–50 mm in length) to the screw holes located at the top (two locations) and on
the lower rear (one location). The screw diameter is M10. Keep in mind that you will need two points at the top to suspend the
unit.
Yamaha cannot be held responsible for damage or injury caused by insufficient strength of the support structure or
improper installation.
The screw holes for eye bolts go through the cabinet wall. When not using eye bolts, tighten the flat-head screws in order to prevent air leaks.
CAUTION
• Before doing any installation or construction work, consult with your
Yamaha dealer.
• The installation should be checked thoroughly at regular intervals.
Some fittings may deteriorate over extended periods of time due to
wear and/or corrosion.
• When choosing the installation location, suspension wire and
mounting hardware, make sure all are strong enough to support the
weight of the speaker.
• Make sure to take precautionary measures using wires to prevent the
speaker from falling down in the event of an installation failure.
• When installing the safety wire to the wall, install it higher than the
wire’s attachment point on the speaker, with as little slack as possi-
ble. If the wire is too long, and the speaker happens to fall, the wire
may snap as a result of too much strain.
• Make sure to use eye bolts according to the standards and safety
regulations in your area.
Safety wire can be attached to the screw holes for
eye bolts and to the screw holes for the U-bracket
(DHR10 only) located at the center of the handle.
The illustration below is an example of using the U-
bracket.
