ARX EC-1 Specifications

Stereo 2 way, Mono 3 way
24dB Electronic Crossover
The ARX EC-1 and EC-2 are both flex-
ible yet affordable 24 dB per octave
Phase Correct electronic crossovers.
They have 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 val-
ue 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.
As a handy guide, a list of common
crossover points and their correspond-
ing 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 sin-
gle channel 3 way mode, with corre-
sponding Outputs on the rear panel.
• Balanced Inputs (and Outputs)
The EC-1 has electronically Balanced
Inputs, on TRS jack connectors, and
the EC-2 has Balanced Inputs and
Outputs, on XLR connectors.
The EC-2 also has an additional
summed Mono Low output, for appli-
cations that need a Mono Low feed
(e.g. Left and Right full-range plus a
single Sub Bass speaker).
• High Pass Filter
Both models feature a preset 30 Hz
HighPass filter to remove unwanted
subsonics which can damage speak-
ers and waste amplifier power.
In addition, each output has up to +6
dB of gain available, to compensate
for amplifiers and speakers of differ-
ing sensitivities.
• Universal AC Power
AC power range is a universal 100 to
120V or 220 to 240VAC, and is con-
nected to the unit via a standard IEC
connector, with built-in fuse and volt-
age change switch.
• Uncompromising Audio Quality
Innovative circuit design is pointless
unless it delivers stunning sound
quality, and here the EC-1 and EC-2
excel. Both are designed for uncom-
promising audio quality, and to
achieve this, Linkwitz Riley 24dB
(Fourth Order) state variable filters
are used throughout their circuitry.
This ensures a smooth Phase Cor-
rect transition through the crossover
region.
From Stage Monitors to Studio Mon-
itors, from Front of House to the Front
room of your House, the ARX EC-1
and EC-2 are both crossovers that
are suited to any application that re-
quires flawless, transparent sound.
