A&E Specifications
The digital audio device features 2 inputs and 6 outputs, capable of driving 3 separate audio amplifiers. All inputs and outputs are balanced analog signals accessed via removable terminal strip connectors with 24-bit analog-to-digital and digital-to-analog converters operating at a 96 kHz sample rate. The frequency response is 20 Hz - 20 kHz, -/+1 dB. Digital signal processing (DSP) functions include parametric equalizer, high pass and low pass filters, horn equalization, crossover (2, 3, and 4-way options), compression, and delay (0-682.656ms), and a 2 x 6 matrix. The processor supports 16 preset memories recallable by remote function. Remote control is accessible via 4 contact input terminals for memory recall, output volume control, and output muting. Switching of preset DSP parameters and matrix selection can be done via Web browser over Ethernet. Output volume can be attenuated using an external analog device. The processor includes control software for PC operation and settings, allowing access to 16 preset memories and a built-in library of manufacturer loudspeakers. Network connectivity is via RJ45 using a switching hub, supporting 10BASE-T/100BASE-TX Auto-Negotiation with TCP/IP protocol. The connection cable should be shielded Cat. 5 or higher twisted pair cable for LAN, with a maximum length of 100 m (109.36 yd.). The unit occupies one EIA component rack space with dimensions of 482 (W) x 44 (H) x 289 (D) mm (18.98" x 1.73" x 11.38"). It weighs 3.1 kg (6.83 lbs) and is finished in black aluminum front panel with a surface-treated steel plate case.
