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

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.

 floating point processor and high performance 24-bit Analog Converters. The high-bit DSP prevents noise and distortion induced by truncation errors of the commonly used 24-bit fixed-point devices. A complete set of parameters include I/O levels, delay,polarity, 6 bands of parametric EQ per channel, multiple crossover selections and full function limiters. The DX 4008 can be controlled or configured in real time on the panel or with the intuitive PC GUI accessed via the RS 232 interface. Software upgrade for CPU and DSP via PC keeps the device current with newly developed algorithms and function once available. Multiple setup storage and system security complete this professional package.
