SAMSON S-3 WAY Stereo/Mono Crossover

The S 3-way is a versatile 2-way, 3-way and 4-way crossover with a difference. First, it's a perfect 2-way
or 3-way stereo crossover. But its mode is also switchable for use as a 4-way mono crossover. The input
gain features +/-12dB range with LED metering and Peak indicators. S 3-way features Low, Mid and High
Frequency outputs with +/-6dB of gain control. Each output incorporates a Mute switch for monitoring the
individual frequency bands and a phase switch to invert the phase of the output. The first crossover point
is sweepable in three ranges: from 35Hz to 800Hz, from 350Hz to 8kHz with the 10X-Multiplier switch
engaged, or from 16Hz to 400Hz in 4 way low-mode. The second crossover point is sweepable from 175Hz
to 4kHz or from 350Hz to 8kHz depending on the setting of the mode switch.
The S 3-way also includes a Delay section with up to 2ms of delay to time-align low frequency outputs for
improved phase response of any PA system. S 3-way's global section features a variable threshold Limiter,
a CD function (for constant directivity horns) and High Pass Filter.

Based on a two-in, six-out topology, the DC-One is designed primarily for users of small-to-medium sized sound systems in both mobile and installed applications. While the unit is an all-new development based on a powerful SHARC processor, it is 100 percent compatible with all settings from other Electro-Voice signal processors. A large part of DC-Oneʼs development was aimed at ensuring that users can easily handle its serious digital horsepower and high-end audio performance. Free. PC-Editor software is available, or the DC-One can be operated via the front panel.   A/D Conversion    24-Bit Delta-Sigma

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
