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.

Weight: 1.7 kg | Behringer DCX2496 Overview
The DCX2496 ULTRADRIVE PRO from Behringer is a digital loudspeaker management system, that provides excellent audio quality, along with a comprehensive feature list. It allows for precise set-up of multiple loudspeaker arrays, suitable for live sound, fixed installations that require control of loudspeaker systems, and other contractor-installed applications.
Each of the three-inputs and six-outputs have fixed processing blocks, including gain, delay, EQ and dynamic EQ on the input channels, and gain, crossover, EQs, limiter and delays on the output side. One of the inputs can accept a stereo AES/EBU digital signal. An integrated sample rate converter assists in accepting various sample rates. Additionally, an internal input-sum signal is easily set-up.
Four different mono and stereo output operating modes are available, all with individual crossover filter types with selectable roll-off characteristics. Input and output delays allow for time adjusting signals to compensate for ambient temperature changes or for adjusting arrival time differences for individual speaker clusters. EQs can be used for both musical enhancement or for level-dependent equalization. Brick-wall limiters guarantee speaker protection.
Remote control of one or several units can be accomplished utilizing downloadable software for a Windows based computer. Set-ups can be saved to the software, or to an optional PCMCIA card for the ultimate in portability. Servo-balanced, gold-plated XLR connectors for all inputs and outputs guarantee excellent connectivity.
