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
