Product Details

Introducing Jupiter.
Jupiter packages powerful DSP into a zero learning curve, turn-key audio processing solution drawing its inspiration from the apps paradigm of smartphones like the iPhone. Standing on the shoulders of Symetrix world-class SymNet DSP platform, Jupiter upholds our commitment to pristine sound.

Hardware: Choice made simple
The three Jupiter hardware offerings differ only in their audio input and output counts. All three use the same software and DSP processes, making your choice of hardware quick and easy.

Software: Easy from the start
Just like using productivity apps on your smart phone, you use Jupiter apps to do specific audio jobs with a simple download to Jupiter hardware. Tap into one of the multiple personalities of Jupiter no design time, zero learning curve. Jupiter handles every task, from automixing to loudspeaker management. The ever-growing library of downloadable Jupiter apps future-proofs your hardware investment.

Engineered by Symetrix
Jupiter brings you controllable and simple to use audio DSP. Engineered and built in the US by Symetrix Explore Jupiter.


Performance Data

  • Number of Inputs: Twelve (12), eight (8), or four (4) switchable balanced mic or line level on Jupiter 12, 8 or 4 respectively.
  • Connectors: 3.81 mm terminal blocks.
  • Nominal Input Level: +4 dBu line or -36 dBu mic level (software selectable) with 20 dB of headroom.
  • Mic Pre-amp Gain: +40 dB.
  • Input Trim: +/- 24 dB.
  • Maximum Input Level: +23 dBu.
  • Input Impedance: > 18 k balanced, > 9 k unbalanced, > 2 k with phantom power engaged.
  • CMRR: > 50 dB @ 1 kHz, unity gain.
  • Mic Pre-amp EIN: < -125 dBu, 22 Hz - 22 kHz, 100 source impedance.
  • Phantom Power: +20 VDC, 20 mA maximum per input.

  • Number of Outputs: Four (4), eight (8), or four (4) line level on Jupiter 12, 8 or 4 respectively.
  • Connectors: 3.81 mm terminal blocks.
  • Nominal Output Level: +4 dBu line level with 20 dB of headroom. For unbalanced analog output, do not connect the minus output terminal. Unbalanced configuration results in 6 dB lower output level.
  • Maximum Output Level: +24 dBu.
  • Output Impedance: 200 balanced, 100 unbalanced.

  • Sample Rate: 48 kHz.
  • Frequency Response: 20 Hz - 20 kHz, +/- 0.5 dB.
  • Dynamic Range: > 110 dB (A-Weighted), input to output.
  • THD+Noise: < -85 dB (un-weighted); 1 kHz @ +22 dBu with 0 dB gain.
  • Interchannel Crosstalk: < -90 dB @ 1 kHz, typical.
  • Latency: < 1.6 ms, input to output with all DSP inactive.

Architects & Engineers 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.
