USB Microphone
The Shure MV51 is a professional-quality USB condenser microphone, ideal for home recording,
podcasting, and video conferencing. The attractive and durable all-metal design features an adjustable
kickstand for desktop use, and can also mount onto a microphone stand. A touch panel user interface
provides control of microphone gain, headphone level, application modes, and muting.
Mounting and Placement
Desktop
Aim the microphone towards the sound source
by adjusting the kickstand.
Microphone Stand
Unscrew the end cap to thread the kickstand
onto a standard 5/8" microphone stand.

Quick Setup
The MV51 is compatible with most devices that have a USB or Lightning connector.
1. Connect the microphone to a computer or mobile device. Use the appropriate cable (USB or
Lightning).
Drivers will be installed automatically. The touch panel illuminates to indicate a successful connection.
2. Open the sound control panel. Select the Shure MV51 driver.
Raise the level on both the MV51 product and the host computer for proper monitoring.
3. Confirm that the MV51 is the selected audio device.
Plug headphones into the MV51 device audio output and play an audio track. If you can hear sound,
the microphone is functioning properly.
If your computer settings default to another device, open the sound control panel and select the
MV51 device.
4. Adjust the headphone volume on the Shure MV51 device driver.
Open the MV51 driver from the sound control panel and raise the headphone volume from the
playback or output tab.
5. Use the MODE button to select the preset mode that fits your application.
If the audio is too quiet or causes distortion, adjust the gain manually. Refer to the "Adjusting
Microphone Level" topic in this guide for more details.
6. In your recording application, select the MV51 as the input source.
See your software user guide for information on assigning input sources.
You are ready to record.

Applications
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.
Podcast and Voice Recording
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.
6-15 ft
(2-4 m)
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.
2-12 in
(5-30 cm)
Set the microphone to the Band mode and make
additional gain adjustments if necessary.
Typical position for speech
Acoustic Instruments and Music
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
0-18 in
(0-45 cm)
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.
Bypass EQ and Compression (Flat)
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.
Set the microphone to the Acoustic or Singing
mode and make additional gain adjustments if
necessary.
Bands and Loud Sources
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.
Additional Tips
Shure offers additional educational publications on
recording techniques for specific instruments and
applications. Visit shure.com for more information.

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
Input Meter Level
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.

Accessing the Control Panel
The MV51 is equipped with a headphone jack to
allow you to monitor audio from the computer and
microphone. The signal is an equal blend of the
direct microphone signal and audio playback from
the computer. The benefit of this feature is that
the headphone settings are conveniently located.
They are easily accessed through the MV51 touch
panel. To adjust the amount of playback audio in
this mix, use the computer or DAW mixer settings.
PC
1. Open the sound control panel and select the
Recording tab.
2. Open the Shure MV51 device.
3. Under the Levels tab, adjust the gain level
using the slider.
Mac®
1. Open the Audio Midi Settings panel.
2. Select the Shure MV51 device.
3. Click on Input to adjust the gain using the
slider.
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
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

Solution
The display does not illuminate Make sure that the MV51 is fully plugged in.
Audio is too low
Check the computer sound control panel settings. When first
connecting the MV51 to your computer, make sure to raise the
computer volume level.
Audio sounds bad
Audio is distorted
Check the sound control panel of the computer to ensure that the
MV51 is fully plugged in and recognized.
Use the audio meter to ensure that volume peaks are within the target
range. If level is reaching the red peak indicator of the input meter,
turn the gain down.
Audio sounds unnatural or

Make sure that the sample rate and bit depth microphone settings,
found in the sound control panel of the computer, are consistent with
the sample rate and bit depth selected in your software.
