The KH 80 DSP two-way active bi-amplified monitor features a DSP engine with network control, a Mathematically Modeled Dispersion™ Waveguide (MMD™), an analogue input 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 80 represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible.
The KH 80 DSP is designed for use as a near-field monitor, as a front loudspeaker in small multi-channel systems, or as a rear loudspeaker in a compact multi-channel systems. It can be used in project and music studios, broadcast centers, OB vans, and post production studios for tracking, mixing, and mastering. It is also well suited for use in domestic environments.
