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.

Getting Started - Audio Connections
The Go Mic Mobile can be connected to a smartphone using the Micro USB digital
output or 3.5mm analog output.
Connecting to an iOS device (iPhone, iPad or iPod Touch)
Using the included Micro USB to Lightning cable, connect the cable to the USB
Audio Output jack on the GMM to the Lightning connector on the iOS device. Once
connected, the iOS device will recognize the Go Mic Mobile as the audio input
device.
Open a recording or video application and start recording.
Note: It is recommended to put your iOS device in Do Not Disturb mode or Airplane
mode to eliminate the video or audio recording from being interrupted by a phone
call. Leave Airplane Mode off to keep geolocation information tagged to your video
files.
Connecting to an Android device with the digital audio output
The Go Mic Mobile will work with Android device running Android 5.0 or later and
have an app that supports USB Audio. To connect using the USB Audio Output
jack, make sure your Android device can accept a digital audio input. Using the
Micro USB to USB type-C or Micro USB to Micro USB cable, connect the cable to
the Micro USB audio output on the GMM and the USB input of the Android mobile
device.
Connecting to a mobile device with the analog audio output
If your mobile device does not accept digital audio input, the GMM can be connected
using the 3.5mm analog output. When connecting to a smartphone, you will need
to set the Analog Output Select Switcb switch to either the Out 1 or Out 2 position.
For most smartphones the Out 1 (CTIA / AHJ) position is the appropriate setting. If
your mobile device uses OMTP wiring for the input, use the Out 2 position. For more
information on smartphone wiring visit www.samsontech.com/support/go-mic-mobile
Connecting to a DSLR, cinema camera, or mixer
When connecting the GMM to a DSLR camera, cinema camera or mixer, use the
included 3.5mm analog audio output. Set the Output Selector switch to the Line/
Headphone setting.
Monitoring with the Go Mic Mobile
The GMM 3.5mm output can be used to monitor the audio transmitted to the
receiver. The headphone output follows the MIX / 2 CH Switch. The level of the
headphones is controlled by the VOL output slider and follows the output level of the
USB Audio Output.

Getting Started - Setting the system volume
Good audio can vastly improve a poorly shot video, but bad audio can hurt any video.
In order to achieve the best results when adding audio to video with the Go Mic
Mobile, it is important to pay attention to the gain staging of the transmitters and
receiver. If the signal is too high, it can overload or distort. Conversely if the signal
is too low, you will need to raise it up in post-production which can add background
noise.
The GMM Receiver CH 1 and CH 2 LEDs include peak or overload indication when
the input to the receiver (signal sent from the transmitter) is overloaded. To set the
level of the transmitters, while talking into the Go Mic Mobile Transmitter, turn the
Gain control (inside the battery compartment) up until you reach a good recording
level. If the corresponding CH indicator flashes red, turn the Gain control down until
you no longer see the indicator flash red or it lights occasionally during very loud
signals.
When the transmitter level is set, perform a test recording to set the level of the
GMM Receiver. If the recording app has an input meter, adjust the GMM Receiver
VOL control until the meter is as close to 0 dB (or clip) as possible without going
over.
Note: The receiver VOL control does not affect the transmitter gain setting. For
example, if the transmitters are sending a distorted signal, lowering the receiver
volume will not fix the audio, it will only lower the overall level of the distorted signal.
MIX / 2 CH Switch
The GMM Receiver can be paired with two transmitters for audio from two
independent sound sources. The MIX / 2 CH switch selects how the audio will be
sent to the audio outputs of the receiver.
In the MIX position the two channels are mixed in mono on both the left and right
audio tracks.
In the 2 CH switch position, the CH 1 transmitter is on the left audio channel and
CH 2 transmitter is on the right audio channel. In 2 CH mode, the inputs can each
be routed to a different track in a computer recording software by creating individual
tracks from the left and right input, or by separating the stereo audio from a video
recording to edit the channels separately in post production.
The MIX / 2 CH Switch mixes the audio prior to the audio outputs of the GMM
Receiver. There are no software changes to the filming or recording application on a
smartphone, camera or computer.
