Architect & Engineer Specifications : Symetrix Radius NX 12×8

The device shall provide twelve analog mic/line inputs that are adjustable from line to mic level with coarse gain, fine trim, phantom power, invert and mute, and 8 analog line outputs that are adjustable with fine gain and mute. All signal processing, mixing and routing functions (including I/O levels) shall be controllable via software. Audio inputs and outputs shall be accessed via rear panel 3.81 mm terminal block connectors.

An option card slot may accommodate either a 2 line VoIP interface card, 2 line analog telephone interface card, 4 channel digital input card, 4 channel digital output card, 4 channel mic/line input card, 4 channel AEC input card, 4 channel analog output card, 8×8 USB audio I/O card, or remain empty.

An internal DSP coprocessor module may be installed for additional application-specific processing such as acoustic echo cancellation (AEC).

A USB 2.0 audio I/O port with class 1.0 legacy modes on a high-retention Type B connection is configurable for up to 8×8 line I/O as well as 2×2 line I/O, 1×1 speakerphone, or 1×1 echo- cancelling speakerphone profiles.

Network audio expansion shall be provided by the Dante protocol with a capacity of 128 (64×64) channels. Primary and Secondary Dante network audio connections shall be provided for redundant network implementation. Connectors 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 display and a momentary switch. The display shall provide communications and system status, I/O metering, 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 eight contact closures or four potentiometer inputs along with eight 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 and RS-232 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 115 dB, A-weighted with a maximum input level of +24 dBu and maximum output level of +24 dBu.
