Jupiter 4 Jupiter 8 Jupiter 12 with ARC-WEB

Jupiter packages powerful DSP into a zero learning curve, turn-key family of audio processors. Standing on the shoulders of Symetrix’ world-class open architecture DSP platforms, Jupiter upholds our commitment to pristine sound.

Three audio input/output options.  Jupiter 4 (4 in, 4 out), Jupiter 8 (8 in, 8 out), and Jupiter 12 (12 in, 4 out).

High feature to cost ratio.  Near zero programming time slashes installation costs.

Over 70 apps for turn-key design.  Categories include mixing and routing, public address / distribution, sound reinforcement, special purpose DSP. Signal routings, whether simple or complex, are fully tested and ready to go right out of the box. Learn more about the available apps Here.

Control made easy.  Multiple control options include zero cost ARC-WEB browser interface and low-cost Symetrix ARC wall panels. A stable, human readable protocol is used to program third-party touch screens.

Incredible sounding DSP.  An abundance of DSP resources power apps that are packed with features like dynamics, EQ, FIR filters, feedback fighters, loudspeaker management, automixing, and matrixing.

Help is built in.  The software connection wizard provides fast and easy IP linking to the DSP hardware. The external control wizard guides effortless programming of multiple user control devices.

Architect and Engineer Specifications

The device shall provide twelve, eight or four inputs (Jupiter 12, 8 or 4 respectively) that are selectable as line or mic level with phantom power and four, eight or four (Jupiter 12, 8 or 4 respectively) line level outputs. All signal processing, mixing and routing functions (including input gains) shall be controllable via software. Audio inputs and outputs shall be accessed via rear panel 3.81 mm terminal block connectors.

The Graphical User Interface (GUI) software shall be installer programmable using the Windows® XP or higher operating system. Computer connection and control shall be via the device’s rear panel Ethernet connector. The GUI shall provide the management of apps, device files and display and control of all signal processing and configuration functions including, but not limited to: Input and Output Gain • Highpass Filtering • Lowpass Filtering • FIR Filters • Crossovers • Parametric Equalization • Graphic Equalization • Expansion • De-Essing • Compression • Limiting • Automatic Gain Control • Ambient Noise Compensation • Feedback Elimination • Automatic Mixing • Priority Mixing • Signal Routing • Delay • Polarity.

The front panel shall include input and output signal level indicators as well as indicators for POWER, NETWORK, and ARC.

External control shall include preset selection as well as I/O level control and muting, and shall be via industry-standard CAT5 cable with RJ45 connectors using the optional ARC wall panel remote controls. 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. Third-party control systems may interface over IP using a published ASCII control protocol.

Audio conversion shall be 24-bit, 48 kHz. The dynamic range of the processor shall not be lower than 110 dB A-weighted.
