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, each input can be
routed to a separate track in your computer recording software. To do this create two
mono tracks, and set the inputs to Samson Go Mic Mobile Left (Input 1) and Samson
Go Mic Mobile Right (Input 2) respectively.
The MIX / 2 CH Switch mixes the audio prior to the audio outputs of the GMM
Receiver. The audio from both transmitters will be present on the left and right audio
tracks of your video or recording software.
