KH 310 A – Active Studio Monitor

KH 310 A – Active Studio Monitor

Product Feature Benefit to the Customer
Powerful alloy fabric dome 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
Reduces reflections off the mixing console
New in-house simulated drivers Latest modeling techniques used to minimize non-linear (intermodulation) distortion
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
Two-color + dimmable Neumann logo Displays operation status and activation of the extensive protection system
Dimmable for low lighting level conditions or behind the screen applications
Compact sealed three-way cabinet design (magnetically shielded) No standing wave resonances
Fastest bass transient response
Reduced intermodulation distortion in midrange
One-piece front panel with no discontinuities Reduced diffraction and smoother frequency response
Powerful analog class AB amplifiers with large headroom Improved transient response
Independent thermo limiters for woofer, midrange dome and tweeter to protect the voice coils. Woofer soft clip and excursion limiters Fast acting, high reliability and allows extraction of the maximum performance from the system
Production consistency due to individual hand-alignment in final test Any KH 310 is “pair-matched” to any other KH 310
4-position bass, low-mid and treble acoustical controls More control in diverse acoustical environments
Wide range input gain and output level controls Easier interfacing with signal sources
Ground lift Reduced noise in electrically noisy environments and over-comes ground loops
Universal switched-mode power supply (100 … 240 V) One version works in any country and robust to poor quality mains supply
Extensive mounting hardware options More flexibility in mounting cabinets in more diverse locations and backwards compatibility with previous models
Optional robust metal grille Can be used, if required, to protect the drivers
Optional transportation accessories Stylish soft carry bag with space for cables
Robust wooden flight case
