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.

The ARX EC-2 is a flexible yet affordable 24 dB per octave Phase Correct active crossovers. It has 2 modes of operation; as either Stereo 2 way or a Mono 3 way units, with a switch on the back panel selecting either mode.
Features Ultra low noise circuitry Totally phase aligned at crossover point Switchable Dual Channel 2 way or Single Channel 3 way Unique 'semi-fixed' crossover point 24dB per octave (Fourth Order) Linkwitz-Riley filters Separate Summed Mono Output Balanced Inputs and Outputs Built in High Pass filters Intuitive, 'user friendly' layout Flawless performance in any audio environment
Tamper-Proof Crossover Points The crossover points are determined internally by the value of 4 resistors per channel; changing the resistor value changes the crossover point. This 'semi fixed' method avoids the pitfalls of externally adjusted crossover points, making the crossover points tamper-proof once they are set. Idle fingers can't fiddle with the crossover points and create havoc with the system! As a handy guide, a list of common crossover points and their corresponding resistor values are printed inside the unit's lid, and also set out in the Owner's Manual. On the front panel are level controls for Low and High in dual channel 2 way mode, and Low, Mid and High in single channel 3 way mode, with corresponding Outputs on the rear panel.
Balanced Inputs and Outputs EC-2 has Balanced Inputs and Outputs, on XLR connectors. The EC-2 also has an additional summed Mono Low output, for applications that need a Mono Low feed (e.g. Left and Right full-range plus a single Sub Bass speaker). High Pass Filter There is also a preset 30 Hz HighPass filter to remove unwanted subsonics which can damage speakers and waste amplifier power. In addition, each output has up to +6 dB of gain available, to compensate for amplifiers and speakers of differing sensitivities. Universal AC Power AC power range is a universal 100 to 120V or 220 to 240VAC, and is connected to the unit via a standard IEC connector, with built-in fuse and voltage change switch. Uncompromising Audio Quality Innovative circuit design is pointless unless it delivers stunning sound quality, and here the EC-2 excels. It has been designed for uncompromising audio quality, and to achieve this, Linkwitz Riley 24dB (Fourth Order) state variable filters are used throughout, ensuring a smooth Phase Correct transition through the crossover region. From Stage Monitors to Studio Monitors, from Front of House to the Front room of your House, the ARX EC-2 is a crossover that is suited to any application that requires flawless, transparent sound. You'll never compromise on Quality when you choose ARX
