Ikan CVM-WM300A Comica Dual-Transmitter Lavalier Microphone Kit
The CVM-WM300A is a dual-transmitter and receiver wireless microphone kit from Comica. This kit runs on built-in rechargeable lithium-ion batteries and has a maximum range of 120m.
To begin using this kit, take out the transmitters and receiver and check the battery charge on each unit. On the transmitters, use the large switch on the side to designate which unit is the A unit and which is the B. Then, you can either assign each a channel manually or use the IR search function to allow the transmitters and receiver to identify which channel has the least amount of interference and automatically assign themselves to that channel. Attach each unit to the user via belt clip, camera cold shoe mount, or an accessory arm via the 1/4-20 mount on the back.
Next, attach the included lavalier microphones to the two transmitters and clip them onto the subjects. Use any of the three included adapters to attach the receiver to the camera, speaker, mixer, or recorder that will be receiving the signal. For real-time audio monitoring, headphones can be inserted into the receiver, next to the Line Out port. Take a test sample of the audio, and begin recording! When you are done, the entire kit and all of its accessories fit neatly into the included hard case.
