Introduction
Congratulations on purchasing the Samson Go Mic Mobile Wireless System. The Go
Mic Mobile is a dual wireless system designed to deliver professional quality audio
for mobile video. Pair and mix two transmitters to the GMM and turn your mobile
device into a complete video production studio. It is the ideal solution for mobile
journalists, filmmakers, videographers or anyone looking to add wireless audio to
their video projects.
The Go Mic Mobile includes all the cables needed to connect the Go Mic Mobile
Receiver (GMM) to a smartphone or digital camera (with an audio input). The Go
Mic Mobile will work with iOS, Android, Mac OS and Windows devices. The locking
mount arms enable the Go Mic Mobile receiver to mount directly onto the rear of a
smartphone out of the way of the phone’s lens. The arms can be removed to attach
the receiver to a tablet (using the included hook-and-loop strips) or affix to a camera
using the included shoe mount adapter.
In these pages, you’ll find a detailed description of the features of the Go Mic
Mobile wireless system, instructions for its setup and use, and specifications. If your
wireless system was purchased in the United States, you’ll also find a registration
card enclosed—don’t forget to follow the instructions so that you can receive
technical support and so that we can send you updated information about this and
other Samson products in the future. Also, be sure to check out our website (www.

Charging the Go Mic Mobile Receiver Battery
Getting the most out of the rechargeable battery:
• Completely charge the batteries before first use
• Fully charge the battery before it will be used.
• After the battery is charged, unplug the adapter from
the outlet.
• The optimal temperature range for using and
storing the battery is 50°F - 86°F (10°C - 30°C).
The battery performance and operation may
decrease in temperatures below 50°F (10°C).
• To extend the battery life, power off the Go Mic Mobile
receiver when not in use.
The Go Mic Mobile Receiver has an internal lithium-ion rechargeable battery. The
receiver is charged via the Mini USB jack located on the side of the receiver.
To charge the receiver, use the included USB charging cable and AC adapter.
Charging may also be done with 3rd party AC 5V adapters, or by connecting the units
to a standard computer USB port.
The total full charge time is 3 hours if you use a fast charger or a fast-charging
USB port (with a lightning symbol next to it), but if connected to a “standard
computer USB port” it will take 10 hours. The max run time from a full battery is
approximately 7–13 hours.
Note: The Go Mic Mobile receiver does not recharge from the Micro USB port, so
the battery level will decrease if plugged into a computer. If you want to power the
receiver while it is connected to a device, you will also need to connect the Mini USB
port to the computer or AC adapter.
