USB Digital Microphone for Content Creators

The Gemini GSM-100 is a cardioid electret condenser microphone with a 14mm by 6.5mm diaphragm. It captures audio at 48KHz/16bit resolution with a frequency response of 50Hz to 20KHz. The microphone connects via USB Type C and draws power from a 5V/1A source. RGB LED grille lighting adds visual flair for on-camera use.

Suited for Streamers and Mobile Recording

This microphone suits podcasters, streamers, and remote workers who need plug-and-play operation across MacOS, iOS, Windows, and Android. The integrated headphone output delivers 100mW maximum power with a 20Hz to 16KHz response for real-time monitoring. Builders who require XLR connectivity or phantom power for studio-grade preamps should look at a different interface.

Simple Setup with Monitoring Caveats

Installation is straightforward: connect the USB Type C cable to a compatible device and select the microphone in system audio settings. The ABS plastic construction keeps weight at 0.25 kg for portable setups. Users must manage gain via software as no hardware knob is present, and the fixed cardioid pattern cannot be switched for multi-person interviews.

Questions about this item

Do I need a device with a USB-C port to plug this microphone in?

Yes, the microphone uses a USB Type-C connector and draws 5 V / 1 A from the host, so the computer, phone or tablet must provide a USB-C port or a USB-C to USB-A adapter.

Will the 48 kHz / 16-bit ADC work with my older USB 2.0 hub?

The interface is USB 2.0 compatible, so the microphone will operate at its full 48 kHz / 16-bit resolution through a standard USB 2.0 hub or port.

How can I confirm the microphone is capturing audio after I connect it?

Select the GSM-100 as the input device in your OS sound settings; the input meter should move when you speak, and the RGB LED grille will illuminate to show the unit is powered.
