JL Audio CR-1 Active Crossover
Brand: JL Audio
Product Code : CR1
The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles. We believe it has no equal, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analog signal purity.
CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass ﬁlters. Multiplying DACs with monolithic ratio matching are employed to adjust the analog circuit's ﬁlter frequencies. This offers superior tracking behavior and far more precise left/right channel balance, compared to conventional approaches.
Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each ﬁlter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.
To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analog audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene ﬁlm-and-foil capacitors and metallized-polypropylene ﬁlm capacitors, to name just a few.
CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.
