Antelope Audio Satori + R4S

Antelope Audio Satori + R4S Monitoring Controller

The Satori delivers mastering-grade monitoring transparency in a compact 1U format, paired with the ergonomic R4S remote for complete control from the mix position. This TEC Award-winning system combines pristine analog circuitry with flexible digital control, making it equally at home in mastering suites, professional studios, and high-end project facilities. The included remote replicates all front panel functionality, allowing engineers to manage sources, outputs, and headphone feeds with tactile precision from anywhere in the room.

Audio Performance & Design

The Satori achieves 132 dB dynamic range and –127 dB THD+N through advanced analog circuit design and optimized power supply technology, ensuring that subtle nuances in your mix remain audible even at lower listening levels. Its innovative patent-pending relay attenuator architecture eliminates the popping and zippering artifacts common in mechanical switches while maintaining 0.05 dB stereo accuracy and stable left-right balance—critical for mastering-grade work.

Connectivity & Control

The system provides eight stereo inputs, four stereo outputs, a dedicated subwoofer output, and four independent headphone outs, with connector options spanning XLR, TRS, and D-Sub 25—unprecedented I/O density for a 1U controller. Control is handled through the front panel, desktop software (Windows and macOS), the included R4S remote with USB 2.0 Type-C connectivity, or a mobile app, allowing multiple users to adjust their own headphone levels while the engineer retains master monitoring control.
