JBL M552 Crossover

The M552 Electronic Crossover give you "constant directivity horn pre-emphasis," a special equalisation curve that optimises the sudio signal for JBL Bi-Radial® horns. The result is a system that delivers balanced power response across both the horizontal and vertical planes for superb coverage.

Key Features:
 
Constant-Directivity horn pre-emphasis allows for smooth, flat frequency response from JBL 2360 Series and 2380 Series Flat-Front Bi-Radial® horns, or other CD horns.
24 dB Linkwitz-Riley filters generate seamless transitions between loudspeaker components for improved high frequency driver protection as well as reduced lobing and phase distortion.
LF summing combines both channels for subwoofer applications where only one mono channel is needed.
Servo-balanced outputs provide automatic output level adjustment to accomodate either balanced or unbalanced feeds.
Outstanding 117 dB dynamic range for lowest noise and greater headroom, resulting in superb transient response.
Extremely low distortion: THD 0.004%.
Wide bandwidth, flat response; 10 Hz to 75 kHz.
Subsonic filtering for protection of low frequency transducers from over excursion.
RF filtering to defeat extraneous noise and ultrasonic oscillations.
External ground link terminals for independent access to signal and chassis grounds, permitting greater flexibility in system grounding.
XLR input and output connectors.
