The Saramonic SR-WM2100 is a compact dual channel 2.4GHz wireless lavalier microphone system intended for portable operation. Ideal for DSLR, Mirrorless and video cameras as well as smartphones and tablets for broadcast TV, electronic news gathering (ENG), on-the-spot interviews and more. With an operating range of up-to 70m in open areas.

The SR-WM2100 includes two bodypack transmitters, each with its own omnidirectional lavalier mics. The transmitters feature a line-level input that lets you wirelessly record the output of a smartphone, audio mixer, or portable recorder to your camera.

The system also comes with a camera-mount receiver that features a gain control to adjust the recording level on your camera. A headphone jack lets you monitor the audio from both transmitters in real time. Equipped with an auto-scan function, the receiver automatically searches and finds a clean transmission frequency to avoid unwanted dropouts. Large, movable antennas and a 5mW RF output power on the transmitters help deliver clear audio at a range up to 230' (line-of-sight). For fast setup time, the transmitters automatically pair with the receiver.

The system conveniently operates on AA batteries. You get approximately 20 hours of continuous use on fully charged batteries. Up to four SR-WM2100 systems can be deployed simultaneously in the same location if more audio channels are needed.

Two Microphones into One Receiver:
  • The two-channel receiver allows you to save space on your shooting rig by using a single receiver to simultaneously receive signals from the two mic/transmitters.
  • The receiver comes with a shoemount adapter for your camera.
  • The audio from both microphones is combined into a mono signal, ensuring that both mics can be heard on the left and right channels of your camera.
