The JBL M552 Electronic Crossover gives you "constant directivity horn pre-emphasis," a special equalization curve that optimizes the audio signal for JBL Bi-Radial horns.
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 accommodate 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.
