KH 120A Active Studio Monitor |
|
Product Code:
KH120A
|
The KH 120 A
studio monitor is designed for use as a near-field loudspeaker or as a rear
loudspeaker in larger multi-channel systems. The KH 120 A represents the latest
in acoustic and electronic simulation and measurement technologies to ensure the
most accurate sound reproduction possible. It has a Mathematically Modeled
Dispersion waveguide (MMD (TM), flexible acoustical controls, analog class-AB
amplifiers, a large headroom analog input and an extensive mounting hardware
range. All of this provides the user with the maximum versatility over a wide
variety of acoustic conditions, source equipment, and physical locations.
The KH 120 is perfect for tracking, mixing and mastering in music, broadcast,
project and post-production studios. |
