This section suggests microphone placement for typical use cases. Keep in mind that there are many effective ways to record a given source. Experiment with the following microphone placement and settings to find what works best.
Set the microphone to the Speech mode. Speak directly into the front of the microphone at a distance of 2-12 inches (5-30 cm) away. Speaking closer to the microphone results in more bass response, similar to voices on a radio broadcast. Make additional gain adjustments if necessary.
Typical position for speech
To capture acoustic sources, such as singing, acoustic guitar, soft percussion, or other musical instruments, use a close microphone placement.
Aim the microphone directly at the sound source. For a single source, such as a string instrument or a vocalist, place the microphone 6 to 12 inches (15 to 30 cm) away. For a small group or a performer who is singing and playing an instrument simultaneously, use a distance of 2 to 10 feet (0.6m to 3 m). Placing the microphone farther away results in more ambient room sound.
Set the microphone to the Acoustic or Singing mode and make additional gain adjustments if necessary.
To record a band with drums or amplified instruments, aim the microphone towards the group at a distance of 6 to 15 feet (1.8 to 4.6 m). Placement of the microphone depends on the size of the room, number of people, and instrument volume. If possible, walk around the room and listen to find where it sounds best.
For other loud sources, such as an electric guitar amplifier, aim the microphone at the sound source from 0-18 inches (0-45 cm) away.
Set the microphone to the Band mode and make additional gain adjustments if necessary.
To record a signal without any processing, set the microphone to the Flat mode. This mode is appropriate for any application when you want to bypass equalization and compression presets, and is ideal when applying signal processing to the recording at a later time.
Shure offers additional educational publications on recording techniques for specific instruments and applications. Visit shure.com for more information.
Use the MOTIV app to change microphone settings and to record, edit, and share audio. The device stores the most recently used settings for quick setup each time you record.
Tip: Turn on Airplane Mode and Do Not Disturb to prevent interruptions to the recording caused by phone calls, text messages, or alerts.
Tap Device on the navigation bar to access the device settings tab.
Microphone Settings
① Connected Mic Status Displays the name of the connected MOTIV microphone.
② Input Meter Displays the strength of the input signal and whether that signal is mono or stereo. The loudest peaks should reach within the target range (indicated by the shaded region between -12 and 0 dB).
③ Microphone Gain/Monitoring Adjust the gain slider to match the volume of the sound source. Tap the headphone icon to turn on the input monitor when making adjustments.
④ Custom Presets Tap the caret to quickly access your saved presets. Or tap the Save button to save current settings as a new custom preset. See Custom Presets for more information.
⑤ Preset Modes Select a mode to set stereo width, equalization, and compression for specific applications. Refer to the "Preset Modes" topic for more details.
⑥ Polar Pattern Selection Swipe to choose between Stereo, Mono Cardioid, Mono Bidirectional or Raw Mid-Side pick-up patterns. Then adjust the width of the stereo microphone pickup area.
Tip: Consider the location of the microphone and the size of the sound source when adjusting the width. For example, a large orchestra or ensemble recording will benefit from a wide stereo image to achieve increased separation between instruments. Other applications, such as speech, benefit from a narrow width for improved clarity with rejection of ambient (room) sound.
⑦ Advanced Features First select a preset mode, then use the advanced controls to fine tune your audio recording and dial in your sound. Your settings will be retained in the microphone. See "Advanced Features," "Wind Noise Reduction" and "Left-Right Channel Swap" for more information on how these features work.
Five selectable modes optimize settings for gain, stereo width, equalization, and compression. Set the microphone level and try 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.
| Mode | Application | Characteristics |
|---|---|---|
Speech |
speech | Narrow stereo width to reject background noise, equalization that emphasizes clarity and fullness, and gentle compression. |
Singing |
solo or group vocal performances | Medium stereo width with subtle equalization to add richness and clarity for a natural sound. |
Flat |
any | An unprocessed signal (no equalization or compression settings used). Adds flexibility when processing the audio after recording. |
Acoustic |
acoustic instruments and quiet music | Medium stereo width with transparent compression to smooth out volume spikes and bring out quiet passages. The equalizer setting emphasizes detail and an overall natural sound. |
Loud |
live performance and louder sources | Wide stereo to increase separation between sources. Equalization further improves definition by reducing frequencies that can make the instrumentation sound crowded. |
Create and save custom presets to quickly access frequently used mic settings.
To access saved presets:
Tip: You can save a custom preset at any point by tapping Save.
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 applications.
Toggle the limiter on to set an input threshold and prevent distortion from volume peaks in your recordings.
Choose no compression, or select light or heavy compression to control volume when your sound source is dynamic. The compressor will narrow the dynamic range, which means that quiet signals are boosted and loud signals are lowered.
Wind Noise Reduction engages a low-frequency cutoff filter that reduces rumble caused by environmental noise. Use the included foam windscreen in combination with wind reduction to counteract rumble and plosives (bursts of air hitting the microphone).
To further reduce wind noise, use the optional Rycote™ Windjammer, which fits over the included foam windscreen.
Change the preset modes to hear the DSP changes, and then use the equalizer to boost or cut bands of frequencies to improve sound clarity.
Note: Equalization within presets will not be displayed. However, the equalizer graphic in the advanced settings status bar displays the user-selected equalization.
Tap to access the MOTIV equalizer. Equalization changes are displayed in the equalizer image.
EQ persists between preset mode changes.
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:
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.
The headphone monitoring level is affected by the MV51 device level and the computer settings level. Raise your computer volume up and easily adjust headphones through the MV51 device headphone settings.

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.
Peak Levels
The target range for peak levels on a typical meter is between -12 and -6 dB.
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.
