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.
