⑥ +20 dB Mic Gain Boost Mic Gain Boost is useful for adding gain to microphones that tend to have a lower output, like dy­ namic microphones.
⑦ Advanced Features Fine tune your audio recording with limiter and compressor controls, and equalization settings.

Preset Modes

Five selectable modes optimize settings for equalization and compression to fit your recording needs. Set the microphone level and select the preset mode that best fits your application. Or experiment with each of the modes to find which sounds best.
Preset modes can affect the strength of the input signal, so adjust the microphone level as needed after changing presets.

Advanced Mic Settings

After you have selected the preset mode for your application, fine tune the sound of your recording with limiter, compressor, and equalizer controls. Your settings will be retained in the microphone when using other audio and video recording applica­ tions.

Limiter

Toggle the limiter on to set an input threshold and prevent distortion from volume peaks in your recordings.

Compressor

Choose no compression, or select light or heavy compression to control volume when your sound source is dynamic. The com­

pressor will narrow the dynamic range, which means that quiet signals are boosted and loud signals are lowered.

Equalizer

Change the preset modes to hear the DSP changes, and then use the equalizer to boost or cut bands of frequencies to im­

prove sound clarity.
Note: Equalization within presets will not be displayed. However, the equalizer graphic in the advanced settings status bar displays the user­selected equaliza­ tion.

Adjusting Microphone Level

Select the correct preset mode for your recording application. If you hear distortion or the audio is too low, adjust the microphone level in the audio or sound control panel of your computer or recording device.

Tips:

Set the microphone level before adjusting headphone volume.
The headphone volume does not affect the signal level sent to the computer.
Use the volume slider on the front panel to adjust the microphone gain level.
Note: The microphone gain control is independent of the preset modes. Set your microphone level and experiment with dynamic processing options via the preset modes.

Adjusting Headphone Level

The headphone monitoring level is affected by the MVi device level and the computer settings level. Raise your computer volume
up and easily adjust headphones through the MVi touch panel headphone control.

Accessing the Control Panel

PC

Open the sound control panel and select the Recording tab.
Open the Shure MVi device.
Under the Levels tab, adjust the volume using the slider.

Mac

Open the Audio Midi Settings panel. Select the Shure MVi device.
Click on Input to adjust the gain using the slider.

Input Meter Level

If your digital audio workstation or recording software has input meters, adjust the microphone level so it peaks between -12
and -6 dB. Otherwise, simply listen to the audio to make sure it is loud enough and not distorting.

Monitoring with the MOTIV Device

The headphone output provides an equal blend of the direct microphone signal and audio playback from the computer. This allows you to conveniently adjust the overall headphone volume with one control on the device touch panel. To change the playback\ audio level relative to the direct microphone signal level, adjust the computer or DAW mixer settings.
Tip: When first connecting the microphone to your computer, make sure to raise the volume level in the sound control panel of the computer for a strong audio signal. Then adjust headphone level on the device for comfortable monitoring.

Sampling Rate and Bit Depth

Sample Rate and Bit Depth settings are found in a drop down menu in the audio or sound control panel of your computer. You can adjust these variables to fit your needs. Select a lower sample rate for podcast recording, when it is important to have a smaller file for easy download. Select a higher sample rate for music and more dynamic recordings.
Tip: Record at a higher sample rate and bounce down to an M4A for a file with the highest sound quality at a manageable size.
Tip for PC users: Make sure that the sample rate and bit depth microphone settings, found in the sound control panel of the computer, match with the sample rate and bit depth selected in your software.

Troubleshooting
