Lightweight and ideal for journalism, audio for video, and documentary applications, the M3 MicTrak from Zoom is a 4-channel, camera-mounted, combination shotgun microphone and recorder, with two internal shotgun mics that can switch between hyper-focused supercardioid (90°) or wider bidirectional (180°) modes at the press of a button. Thanks to dual AD converter circuits inherited from the pro F-Series recorders, no gain adjustment is necessary, and the M3 captures quality audio in 48 kHz / 32-bit floating point for crisp sound without clipping.
The M3 sports a 3.5mm headphone output for real-time monitoring and a 3.5mm stereo line out for sending your audio directly to an external recorder, such as a camera audio input or a secondary field recorder. The M3 is fully compatible with microSD cards for onboard recording, minimizing the amount of equipment you need with you on shoots, and can run on two AA batteries, USB-C bus power, or an optional Zoom AD-17 AC adapter (sold separately).
- 32-bit floating point recording provides excellent headroom and helps to avoid clipping issues
- High max SPL of 132 dB delivers further protection against clipping for loud sound sources, such as performances, crowds, or other high SPL environments
- 12 hours of battery life for improved operating time and multiple power options including AA battery, USB bus power, or AC adapter (sold separately)
- Dual AD converter circuits, derived from the F-Series, make manual input gain adjustment unnecessary
- Support for broadcast and film quality BWF wav format
