3.1 Cardioid Pickup Pattern
The microphone utilizes a cardioid polar pattern, which primarily captures sound from the front of the microphone. This design helps to minimize background noise from the sides and rear, focusing on the main sound source directly in front of it.

3.3 Microphone Gain Control
Adjust the microphone's input sensitivity using the mic gain knob located on the device. Rotate the knob to increase or decrease the gain, allowing you to achieve the desired recording volume and clarity.

For real-time audio monitoring without delay, plug your headphones directly into the 3.5 mm jack on the microphone. This feature allows you to hear your audio input as it is being recorded, ensuring accurate sound capture and preventing recording errors.
