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.

Full-featured Speaker Processing in a 1U Space
Speaker processing can be a complicated business requiring a substantial array of equipment, but the Yamaha SP2060 offers everything you need in a single rack space. This innovative 24-bit, 96-kHz digital speaker processor delivers excellent sound quality, an impressive variety of processing functions — gain, delay, PEQ, comp, crossover, limiter, and an all-pass filter for phase adjustment — and intuitive programming from Yamaha's DME Designer application running on a personal computer. It has two analog inputs and six analog outputs, plus two AES/EBU format digital inputs for connectivity with a broad range of systems. And if you use Yamaha Installation Series Speakers, all you need to do is select one of the many optimized presets provided for great sound with minimum measurement and setup time. The SP2060 is a compact, portable 1U unit that is ideal for live sound or installations.

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
