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

More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 234xs Crossover you'll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The 234xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 234xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 234xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs.
