Active Studio Monitor RL 900A.
The active three-way monitor RL 900A is a good choice for an all purpose main loudspeaker in Audio- and Video production studios. The mid- and high-frequency driver is coaxial composite with a 15" bass system. Through the operation in a bass reflex cabinet is reaching an optimal efficiency. The mid range system has a kidney-shaped radiation characteristic, so that the directivity index completes himself with the bass system. We spend much effort in developing constructive ways to ensure a low degree of non-linear distortion and high fidelity of sound. The speakers power concentration is designed for a long distance monitoring situation. The whole system provides a high acuity of focus. The three-way MOSFET-amplifier with active crossover is situated at the back of the cabinet and is easily accessible for maintenance. An intermittent LED indicates sound pressure levels within the overload margin of 3 dB and warns of clipping. Beyond this limit the output level of the high- and mid-frequency drivers get damped by 20 dB to protect the speaker's components. To compensate their placement the speaker features two controllers to continuously adjust the low-frequency response. There are various stands available as optional extras, which fit in the integrated appliance. We also offer this monitor magnetically shielded.
