Sonosax SX-R4+





Sonosax SX-R4+ [SX-R4+]
The Sonosax SX-R4+ is a 16-track recorder with dual SD-card recording and an I/O architecture that combines analog mic/line and digital AES3/AES42 sources. The four XLR inputs are individually configurable as analog (mic/line) or digital (AES3/AES42 with ASRC), with front-panel control. Recording is uncompressed BWF with iXML metadata on 2× SD (SDHC/SDXC), with sample rates from 44.1 to 192 kHz at 24- or 32-bit. Timecode is provided on a Lemo connector with independent in/out.
Main Features
- Up to 16-track recording on 2× SD cards (SDHC/SDXC).
- 4× XLR-3F inputs, individually configurable as analog mic/line or digital AES3/AES42 (with ASRC).
- Front-panel per-channel control: level control, LF cut and phase reversal; analog also provides 48 V phantom.
- 2× electronically balanced line inputs on TA-3 with front-panel level control.
- WiFi dynamic web-app interface and 2.4" TFT color touch screen.
- Timecode accuracy 0.5 ppm; 23.976 / 24 / 25 / 29.97 DF/NDF / 30 DF/NDF.
