The XR-Series crossovers are the product of an intensive research effort started in 1972 which combined a reexamination of traditional crossover theory with practical field use. Over the years, a number of refinements and new models have been added to our crossover series, but the original design goals have remained the same: to produce a crossover which is sonically accurate, is flexible enough to suit a wide variety of systems, and affords maximum protection for speakers and drivers.
All Ashly crossovers are based upon the same powerful state-variable filter circuit, which guarantees 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, 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.
Response Control an Ashly Exclusive... 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. The 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 "Linkowitz-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.
The purpose of this control is to help offset the inaccuracies inherent in typical loudspeakers, thereby helping you to achieve a flat system response. NOTE: The Response control is not a "slope" control. A 24dB/octave crossover will always have a slope of 24dB/octave. The Response control only affects filter response shape in the immediate vicinity of the crossover frequency; the ultimate crossover slope is a fixed parameter.

Providing 48-bit filter algorithms, 24-bit AD/DA conversion and a dynamic range of 115 dB, the DSP 244 sets new standards for digital loudspeaker controllers and processors. The DSP 244 is an universal Digital Sound System Processor that provides 2 inputs and 4 outputs; plus internal summing of the inputs 1 and 2. Via matrix it is possible to assign the outputs to any input or to the sum of the inputs. It is further possible to establish the following configurations: Stereo or Dual 2-Way systems, 3-Way + Direct and 4-Way systems, each with Mono Subchannel, but also full range systems. High and low-pass filters are provided for the frequency crossover functions in all operation modes. The selection includes Linkwitz-Riley, Butterworth and Bessel type filters with switchable slopes between 6, 12, 18 and 24 dB/oct. A huge number of additional filters offers extremely flexible correction of the frequency response. Each input incorporates a 5-band equalizer, allowing to assign high and low-pass, high and low-shelving or parametric peak-dip filters to its individual filter sections. Next to the frequency crossover filters, four additional filters are employed in each output channel, which also can be set to work as high or low-pass, high or low-shelving filters, parametric peak-dip filters, or all-pass filters. Additional filtering is provided through 2. order high-passes for the realization of B-6 alignment, or special LPN-filters (Low-Pass Notch filters) for correcting the frequency and phase responses of optimally vented woofer cabinets. Each channel additionally provides a delay, a polarity switch, a programmable level control and a digital compressor / limiter while the master delays are located in the input channels.
