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.
