The SR-M3 features a headphone output, allowing you to always hear your sound, even if your camera lacks a headphone jack. An additional 3.5 mm microphone input enables the connection of a second microphone. If your camera has only one microphone input, you can use two with the SR-M3. You can connect a plug-on lavalier microphone, such as the Saramonic SR-XLM1, or an additional shotgun mic, like the Saramonic SR-PMIC1. The SR-M3 also includes a +10 dB boost switch, which allows you to lower your camera's noisy preamp to capture much cleaner audio data and record objects from a greater distance. This is an excellent-sounding shotgun microphone that delivers rich and clear sound. It is compact, has a built-in camera shoe mount, and the wired output cable cannot be left behind after a recording. The built-in mount features a metal 1/4 20 tripod thread, providing you with even more mounting options, and the integrated shock mount isolates the microphone from vibrations. A low-cut switch on the back of the SR-M3 makes dialogue clearer and eliminates distracting noises like the low rumble of vehicles. The additional headphone output of the SR-M3 can also be useful if your camera has a headphone jack. The headphone output of the SR-M3 is set to a pleasantly high volume and is likely louder and easier to hear than your camera's headphone output.
