The Saramonic 4-Channel VHF Lavalier Microphone System allows you to wirelessly record audio from up to 60 metres away. Offering high fidelity audio and reliable performance in a cost-effective unit, the system is ideal for small budget film makers, YouTube and internet content creators, and anyone looking for a simple, portable system with intuitive controls. The SR-WM4C consists of a camera-mountable receiver, body pack transmitter and an omni-directional clip-on Lavalier microphone.

4 Selectable Channels

The SR-WM4C system offers 4 switchable channels in the high band VHF operating frequency range of 203MHz to 216MHz to provide interference-free audio. An operating range of up to 60 metres provides you with plenty of movement as well as camera placement options.

Portable Receiver

The wireless receiver unit features headphone output with a volume control dial for real-time monitoring. It mounts to your camera’s hot shoe using an included adapter with 1/4 inch thread that can be used with compatible tripods. When using the receiver with portable audio recorders, the hot shoe adapter can be swapped with the included extra belt clip for hands free use.

Discreet Body Pack Transmitter

With a compact and discreet design, the body-pack transmitter can be easily hidden in pockets or attached to belts while still providing good access for mic attachment. The flexible aerial is detachable and has 360° rotation for better sound quality adjustment.

Lavalier Microphone

The omnidirectional Lavalier mic plugs into the transmitter via a 3-pin mini XLR terminal with a locking pin for a solid connection. The clip-on mic has a low profile and sits on the clothing unobtrusively. It also has a wind shield to help reduce noise distortion for better quality audio.

Powered by AA Batteries

The SR-WM4C Transmitter and Receiver are both conveniently powered by two AA size batteries (not included) that provide up to 5 hours of continuous use. Easy to see LED power indicators on both units makes it easy to check their remaining battery life so you’re never caught out.

Compact and Lightweight

The small form factor and low weight of the entire system makes it ideal for use with DSLRs and smaller camcorders. It’s easy to transport, with highly flexible aerials that can be detached for easy, safe storage.


The Saramonic SR-WM4C is compatible with DSLRs, camcorders, and other audio recording devices with a 3.5mm microphone jack. A separately available adapter allows you to mount two receivers on a single camera, enabling audio recording from two different sources.
