| Content | Advanced Feedback Suppression Processor with Full LCD Display
The AFS2 Dual-Channel Advanced Feedback Suppression Processor from DBX protects your ears and audio equipment from annoying and potentially damaging audio feedback without altering your sound. The AFS2 features application-specific filter types for speech, music low, music medium, and music high. The 24 fixed or live narrow-band notch filters are capable of removing frequencies at 1/80 of an octave, ensuring an optimal frequency response without the possibility of feedback.
The front panel features the wizard function to take the guesswork out of setting up any room by incorporating an advanced feedback suppression module and providing a full LCD display for system settings and menus. Additionally, the AFS2 offers a five-segment LED for accurately monitoring input levels for each channel, while the notch filter indicator allows you to monitor the number of filters applied. Dedicated bypass buttons are included to help isolate problem channels. The rear panel offers XLR and 1/4" inputs and outputs, both switchable between +4 and -10 dB operations. A USB port has been provided for firmware updates. The AFS2 ships with a standard IEC power cable.

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

| Behringer DCX2496 Overview
The DCX2496 ULTRADRIVE PRO from Behringer is a digital loudspeaker management system, that provides excellent audio quality, along with a comprehensive feature list. It allows for precise set-up of multiple loudspeaker arrays, suitable for live sound, fixed installations that require control of loudspeaker systems, and other contractor-installed applications.
Each of the three-inputs and six-outputs have fixed processing blocks, including gain, delay, EQ and dynamic EQ on the input channels, and gain, crossover, EQs, limiter and delays on the output side. One of the inputs can accept a stereo AES/EBU digital signal. An integrated sample rate converter assists in accepting various sample rates. Additionally, an internal input-sum signal is easily set-up.
Four different mono and stereo output operating modes are available, all with individual crossover filter types with selectable roll-off characteristics. Input and output delays allow for time adjusting signals to compensate for ambient temperature changes or for adjusting arrival time differences for individual speaker clusters. EQs can be used for both musical enhancement or for level-dependent equalization. Brick-wall limiters guarantee speaker protection.
Remote control of one or several units can be accomplished utilizing downloadable software for a Windows based computer. Set-ups can be saved to the software, or to an optional PCMCIA card for the ultimate in portability. Servo-balanced, gold-plated XLR connectors for all inputs and outputs guarantee excellent connectivity.
