Architect and Engineer Specifications: Prism 4×4.

The half rack device shall provide four analog mic/line inputs that are adjustable from line to mic level with coarse gain, fine trim and phantom power plus four analog line outputs that are adjustable with fine trim. Levels, phantom powers, signal inversions and mutes shall be controllable via software. Audio connections shall be accessed via rear panel 3.81 mm terminal block connectors.

Network audio expansion shall be provided by the Dante™ protocol with a capacity of 128 (64×64) channels. The connector shall be 1000 Base-T RJ45 utilizing CAT6 cable.

A designer software application shall be provided that operates on a Windows computer, with network interface installed, running Windows® 7 or higher operating system. Computer connection for configuration shall be via the device’s rear panel Ethernet connector. All internal processing shall be digital (DSP). Available DSP components shall include (but not be limited to) various forms of: mixers, equalizers, filters, crossovers, dynamics/ gain controls, routers, delays, remote controls, meters, generators, onboard logic, and diagnostics.

The front panel shall include a white on black 256×64 pixel OLED display and momentary switch. The display shall indicate unit name, IP address, MAC address, Site File version, and fault messages.

External control shall include dedicated software screens as well as preset selection, I/O level control and muting using the optional ARC wall panel remote controls via industry-standard CAT5 cable with RJ45 connectors. A built-in web server shall provide four instances of ARC-WEB, which allows for user control from nearly any web browser or mobile device. Logic I/O shall consist of four contact closure or two potentiometer inputs along with four logic outputs. The logic outputs may be used to drive LEDs directly or control external relays or switchers. All program memory shall be non-volatile and provide program security should power fail. The device shall provide an on board real time clock to facilitate automatic, timed changing of presets and may sync to NTP. Third-party control systems may interface over IP using a published ASCII control protocol.

Audio conversion shall be 24-bit, 48 kHz and internal processing shall be 32-bit or 40-bit floating point, 48 kHz. The dynamic range shall not be lower than 113 dB, A-weighted with a maximum input level of +23 dBu and maximum output level of +24 dBu.

The device shall be powered over Ethernet (PoE+) by an IEEE 802.3at Class 4 standard compliant switch, or the included injector. The device can be powered from either the Dante or Host RJ-45 port. The device shall meet UL/CSA and CE safety requirements and comply with CE and FCC Part 15 emissions limits. The device shall be RoHS compliant. The chassis shall be constructed of cold rolled steel, and may be surface mounted or mount into a standard 19” 1U EIA rack using an available bracket or rack tray. The device shall be a Symetrix Prism 4×4.
