About the EC-2
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.

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
