Output Mute switches on each channel are included for convenient and accurate setup operation, and a peak overload indicator monitors all critical points in the circuit to ensure low-distortion operation. A recessed switch on the front panel with an LED indicator allows for either normal or "divide by ten" frequency selection. The XR Series II models feature Ashly's exclusive "Response" control, allowing the user to select the best performance for a given application. The purpose of this control is to help offset the inaccuracies inherent in typical loudspeakers, where many anomalies can occur at the crossover point. This Response control adjusts the damping of the filter, affecting its shape near the crossover point. The "Butterworth" response, for instance, results in a gentle 3dB rise when the two filter output signals are combined. Similarly, a "6dB" setting produces a "Linkwitz-Riley" response for flat summing. Other responses are possible to correct for driver, cabinet, and room problems at the crossover point. No other crossover offers the ability to dynamically shape filter response as precisely. For the ultimate in sound system control and accuracy, the XR Series II models are the logical choice. 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 or mono four- (or five-) way, or even as a four-channel two-way configuration for bi-amplifying onstage monitor systems. The XR-4001 fulfills the needs of four-way stereo setups. All Ashly crossovers are U.L. Listed and backed by our exclusive Five Year Worry-Free Warranty.
