The Jupiter 4 is a professional audio DSP processor delivering four switchable balanced mic/line inputs and four line-level outputs. Engineered by Symetrix for pristine sound quality, it features comprehensive signal processing including parametric and graphic equalization, compression, limiting, expansion, automatic mixing, and routing. Operating at 24-bit/48 kHz with >110 dB dynamic range (A-weighted), it provides low latency (<1.6 ms) performance. The unit utilizes a zero learning curve "apps" paradigm for specific audio processing tasks. Housed in a 1U rack-mountable chassis with 3.81 mm terminal block connectors, it connects via Ethernet for control and integrates with ARC remote panels.
