   Note: The first time you connect the MVX2U, phantom power will be on. Be sure to turn phantom power off in the MOTIV Desktop app if you are using a ribbon microphone. Phantom power can damage a sensitive ribbon microphone. You can find the phantom power toggle in MOTIV Desktop app settings.

Auto Level Mode

Use the following suggestions as a great starting point for your most common recording needs. Keep in mind that there are many effective ways to mic a voice. The closer you can get to the microphone, the better, but Auto Level Mode really helps to get you sounding your best. Experiment to find which mic placement works best for you.

Near
For podcast and voice recording applications. Position the microphone in front of and as close to your face as possible. Speak directly into the mic, 1-6 inches (2.54 – 15 cm) away for a more intimate voice sound with maximum rejection of off-axis sounds. Make additional gain adjustments if necessary.

Far
Ideal when the sound source is further from the microphone, like in gaming when the person needs to be closer to the screen or gaming console. Aim the microphone directly at the sound source. Place the microphone 6 to 18 inches (15 to 45 cm) away from the sound source. Make additional gain adjustments if necessary.
Tip: Ensure that the microphone is directly pointed towards the source. If possible, experiment with mic placement to find where it sounds best. Make additional gain adjustments as necessary.

Additional Tips

   Note: The first time you connect the MVX2U, phantom power will be on. Be sure to turn phantom power off in the MOTIV Desktop app if you will be using a rib­bon microphone. Phantom power can damage a sensitive ribbon microphone.

4. Mic Mute / Mic Gain Use the toggle to mute and unmute your microphone. Use the slider to control microphone gain.
   Note: Some programs can control microphone gain while in Manual mode.

5. Monitor Mix slider Move the slider to adjust the levels of mic and playback sound sources. See “Monitor Mix Blend” for more information on monitoring.

6. Equalizer Use the 5-band parametric equalizer to adjust the gain of independent frequency ranges, to precisely shape the frequency response. Tap Reset to return to an unchanged equalization state.

7. High Pass Filter, Limiter and Compressor settings Fine tune your audio with filtering, limiting and compressor controls. See “Advanced Mic Settings” for more information.

Preset Modes
Four selectable modes optimize settings for gain, equalization, and compression. Try out the modes to find which sounds best for your room and recording application. Preset modes can affect the strength of the input signal, so adjust the microphone lev­el as needed after changing presets.

and gentle compression.

Dynamic Mic – Singing

| Subtle equalization to add richness and clarity for a natural sound when cap­

turing solo or group singing.

Condenser Mic – Speech

| A more sensitive signal that emphasizes spoken clarity and fullness with gen­

tle compression.

Condenser Mic – Singing

| Transparent compression to smooth out volume spikes and bring out quiet passages in sung performances. The equalizer setting emphasizes detail and an overall natural sound.

Custom Presets

• Create and save custom presets to quickly access frequently used mic settings.
  1. Start with the preset mode that best suits your application needs.
  2. Adjust advanced settings, like compression, for clarity and consistency.
  3. Tap Save to rename and save your new custom preset. The original preset will remain available.
  4. The new custom preset is added to your list.
• To access saved presets:
  1. Tap the caret (arrow) in the Preset row to view your list of available presets.
  2. Tap custom preset and Apply Preset to instantly apply gain, equalization, and compression preferences.
     Tip: You can save a custom preset at any point. Tap Save and give the current settings a new name.

Monitor Mix Blend

Use the monitor mix slider to adjust how much of each source you can hear. For best results, start monitoring at the midpoint and adjust.

• Move the slider towards the microphone icon (Mic) to hear more of the audio going into the mic. Like when you’re singing over a recorded guitar track and want to clearly hear your voice.
• Move the slider towards the device icon (Playback) to hear more of the track playing back. When you’re recording a har­mony to your original vocal track and want to clearly hear the original performance.

Advanced Mic Settings

After selecting the preset mode, fine­tune your sound with limiter, compressor, and equalizer settings. These settings are re­tained in the microphone when using other audio and video applications.

• Limiter
  Toggle the limiter on or off to prevent distortion from volume peaks in your recording.

• Compressor
  Choose no compression on your sound, or select light, medium or heavy compression to control volume peaks when your sound source is dynamic. Compression boosts quiet sounds and lowers louder sounds to make sound levels more even.

• High Pass Filter

• • Choose no HPF for the most natural sound. Or select 75 Hz or 150 Hz to reduce wind noise, room noise, or proximity effect.
  • 75 Hz Low frequency cutoff Provides a 6 dB-per-octave cutoff at 75 Hz. Helps eliminate floor rumble and low-frequency room noise from heating and air conditioning systems. This setting may also be used to compensate for proximity effect or to reduce low frequencies that make an instrument sound dull or muddy.
  • 150 Hz Low frequency rolloff Provides a 6 dB-per-octave rolloff filter at 150 Hz. Use this to compensate for proximity effect or to reduce low frequencies that could make an instrument sound dull or muddy.

• Equalizer
  Use the equalizer to boost or cut bands of frequencies to filter out unwanted sounds and improve sound clarity.

Streaming Tips

• Control your Levels
  To ensure consistent volume levels, determine the microphone placement that works best for you and maintain that distance. Record several practice tests to determine the spot where your voice sounds best and background sounds are minimized.

• Monitor Your Sound
  To hear your audio with no latency, plug headphones into the headphone output on your MVX2U.

• Mounting Instructions
  The MVX2U interface fits into a standard A25D mic clip. So you can place it anywhere that you can put a standing or tabletop mic stand.

Troubleshooting

Audio is distorted

|

Audio distortion usually comes from overloading the microphone which causes clip­

ping. Lower your mic gain for the best sound recording.

Select Auto Level Mode to allow the software to control audio settings. Near for up- close applications (1-6 in. / 2.54-15 cm) and Far for a distance of 6-18 inches. (15-45 cm)

Check that the all cables are correctly and completely connected.

If listening through headphones, check the connection or try using a different pair.

You hear no audio and MOTIV Desktop app reads “No Mic. Dis­ connected.”|

Check that the all cables are correctly and completely connected.

If listening through headphones, check the connection or try using a different pair.

You hear no audio even though the desktop application is dis­ playing the correct microphone.

|

If you are using a condenser mic, check the Phantom Power toggle in the MOTIV Desktop app to ensure that you are providing power to your condenser microphone. The +48V LED will illuminate on the MVX2U.

Check the Monitor Mix slider. Move the Monitor Mix slider to the center to ensure that you are listening to a balance of audio going into the mic and the audio being played back at the same time.

Note: Playback audio will only be heard when playing back the track.

General troubleshooting

|

Disconnect and reconnect the MVX2U. Quit and re-start the app.

Reboot the computer.

Check for firmware update. Tap the three dots in the top right corner and select
