This MA-400 Microphone Adapter from Canon is compatible with the Cinema EOS C300 Mark II and XC15 4K camcorders. By attaching the microphone adapter to your camcorder, you can use the adapter's input terminals to record audio independently to two audio channels from an external microphone or analog audio input source with an XLR connector. The microphone adapter supports 48V phantom power, which is powered by the camcorder's power supply.
The MA-400 is geared toward single-user applications such as run-and-gun news gathering. It mounts to your camcorder's accessory shoe and offers an external mic holder to which you can mount external microphones with a diameter of 0.75 to 0.79". Included is a microphone cable clamp.
