Saramonic SR-PAX1 On-Camera Audio Mixer for DSLR, Mirrorless & Video Cameras
The Saramonic SR-PAX1 is a compact 2-channel on-camera audio mixer built for creators who need to connect and manage multiple microphones and audio sources while recording to DSLR, mirrorless, cinema, and video cameras with a 3.5mm (1/8") mic input. With broad input compatibility and a rugged all-metal build, it’s designed to deliver dependable, production-ready audio control in a travel-friendly form factor.
Two locking XLR / 1/4" (6.5mm) TRS combo inputs support professional microphones, line-level sources, and even instruments, while three 3.5mm (1/8") inputs expand options for video mics, stereo mics, and additional sources. A front-mounted headphone output makes it easy to monitor audio in real time, and bright LED indicators help you confirm settings quickly during shoots.
