The Saramonic SR-VRM1 Plug-On Linear PCM Recorder is a compact, all-metal solution that transforms any XLR microphone into a fully cable-free recording system. By connecting directly to the microphone’s XLR connector and supplying 48V phantom power, it supports both dynamic and condenser mics — delivering broadcast-quality 24-bit / 48 kHz WAV audio without wireless interference, perfect for interviews, press conferences, and field recording.
Recording directly to microSD or microSDHC cards (up to 32GB), the SR-VRM1 can store up to 60 hours of audio at maximum quality — or up to 180 hours at 16-bit / 24 kHz. An easy-to-read LCD display, adjustable gain control, switchable low-cut filter, and a 1/8″ headphone monitor output give you full command over your audio in any environment, all powered by just two AA batteries for up to 8 hours of operation.
