Neumann KH 310D Active Studio Monitor with Digital Input and Delay |
|
Product Code:
KH310D
|
| The KH 310 D three-way active tri-amplified
monitor features a Mathematically Modeled Dispersion� Waveguide (MMD�), flexible
acoustical controls, various input options (analog and digital) and an extensive
range of mounting hardware. This allows the loudspeaker to be used in diverse
acoustical conditions, with any source equipment and in a wide variety of
physical locations. The KH 310 represents the latest in acoustic and electronic
simulation and measurement technologies to ensure the most accurate sound
reproduction possible.The KH 310 D is designed for use as a near-field monitor,
as a front loudspeaker in mid-sized multi-channel systems, or as a rear
loudspeaker in a larger multi-channel system. It can be used in project, music,
broadcast centers, OB vans, and post production studios for tracking, mixing,
and mastering. |

Low-distortion
high-frequency reproduction |
Elliptical
Mathematically Modeled Dispersion� (MMD�) waveguide, with wide
horizontal and narrow vertical dispersion
|
|
Smoother off-axis response,
More forgiving of diverse acoustical environments
Freedom of movement across the mixing console

|
Fabric dome,
neodymium magnet, midrange driver |
|
Dedicated driver reproduces
important midrange frequencies, which is especially important for speech
and vocals
Light weight dome has better transient response and less breakup modes
than cone designs
High power magnet reduces harmonic and intermodulation distortion |
|
Long throw composite
sandwich cone bass driver with Extremely Linear Force Factor� (ELFF�)
and ribbed surround |
|
Damping of break-up modes
and low distortion at high sound levels
Linear pistonic motor gives a very low harmonic distortion even at high
excursions
Reduced radial break-up modes on the ribbed surround |
