Operating Instructions
1. Powering On/Off
Locate the power switch on the microphone. Slide it to the "ON" position to power on the microphone. Slide it to "OFF" when not in use to conserve battery life.
2. Using the +10dB Audio Gain Switch
The SR-M3 features a +10dB audio gain switch. This switch boosts the microphone's output level, which can be useful in situations where the camera's preamps are noisy or when recording quiet sound sources. Engage this switch if your audio levels are too low.
3. Using the 200 Hz Low-Cut Filter Switch
The 200 Hz low-cut filter (also known as a high-pass filter) reduces low-frequency sounds such as rumble, wind noise, or air conditioning hum. Engage this switch when recording in environments with unwanted low-frequency interference.

4. Connecting an External Microphone (Optional)
The SR-M3 includes an extra 3.5mm microphone input. This allows you to connect a second microphone, such as a lavalier microphone, for dual-source recording. The audio from both microphones will be mixed into a single stereo track.
5. Monitoring Audio
Connect headphones to the 3.5mm headphone monitor jack to listen to your audio in real-time. This is crucial for ensuring proper audio levels and identifying any potential issues during recording.
