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.
