The XR-1001 is a stereo two-way or mono three-way crossover the XR-2001 offers the unique ability to operate as a stereo three-way, a mono four (or five) way, or even in a four-channel two-way configuration for bi-amplifying on-stage monitor systems and the XR-4001 fulfills the needs of four-way stereo setups. XR crossovers are sonically accurate, are flexible enough to suit a wide variety of systems, and afford maximum protection for speakers and drivers.

Ashly’s XR-Series crossovers are based upon a powerful state-variable filter circuit guaranteeing that two adjacent frequency band outputs always remain in phase. Our crossovers offer a number of useful and unusual features, including continuous tuning, a response control, and a unique output stage which maintains low noise at any level setting. These models also include a 200:1 tuning range, individual output mute switches, and both TRS and XLR connectors. Like other Ashly products, your crossover features low noise and distortion, active balanced inputs, a peak level indicator, a precision regulated power supply, protection against abnormal input or output conditions, and rugged mechanical construction. Conservative design and an unusually thorough procedure for quality control have earned Ashly a reputation for dependability in the recording, sound reinforcement, and broadcast fields.

This control, found adjacent to the crossover frequency control, adjusts the damping of the filter affecting the response shape of the filters at the crossover point. This helps offset the inaccuracies inherent in typical loudspeakers, thereby helping you to achieve a flat system response. Dial calibrations refer to the amount of attenuation effected by the filter at the crossover frequency, i.e., a setting of 3dB means that the filter’s high-pass and low-pass outputs are each “rolled off 3dB at the crossover point”. This describes Butterworth filter response, or a gentle 3dB peak at the crossover point when the two filter output signals overlap. To obtain a flat signal, or “Linkwitz-Riley” response through the crossover region, set the Response control to “6”. This attenuates each output of the filter by 6dB at the crossover point (two identical signals added together yield a +6dB increase). To obtain a notch at the crossover point, turn down the response control past "6" to best suit your needs.
