General Description

The Shure P3RA bodypack receiver works with Shure P3T transmitters as part of the PSM300® stereo personal monitoring system. An advanced user menu featuring an LCD display delivers increased functionality over the standard PSM300 bodypack receiver, while an all-metal housing provides superior durability. Compatibility with the Shure SB900B rechargeable battery delivers improved battery life and provides an environmentally friendly way to save money and reduce waste.

For more information on using the P3RA with the PSM300 system, refer to the PSM300 user guide (included with the transmitter and available at

Note: To remove, open the door and slide the adapter out. To reinstall, press the adapter into place—there is an audible click when seated.

Audio Settings

MODE STEREO: Audio from channel 1 is heard on the left earphone; audio from channel 2 is on the right earphone.MIXMODE: Both channels are heard on the left and right earphones. The blend between mixes is adjustable.
EQ Use the two-band shelving equalizer to boost either bass or treble frequencies up to +6dB in 2 dB increments.

LOW BOOST: Boosts frequencies below 100 Hz

HIGH BOOST: Boosts frequencies above 10 kHz

OFF: No EQ (flat)

VLIMIT (Maximum Volume) Set a value (-3 to -21 dB, adjustable in 3 dB increments) to attenuate the highest possible volume level. Turning the volume knob through its entire range of motion still affects volume; the limit simply narrows the range of dB adjustment.

Note: The VLIMIT does not compress the audio.

BAL MX / BAL ST (Balance) The behavior of the balance control depends on which mode the bodypack is set to:

STEREO: Adjusts the left/right balance

MIXMODE: Adjusts the blend between channel 1 and channel 2


CONTRAST Customize the display screen contrast by selecting a setting between low and high
LOCK PANEL Locks all controls except the volume knob to prevent accidental changes to settings


Unlock: Press the exit button and select OFF when the lock setting screen appears. Press enter to confirm.

BATTERY Displays remaining battery runtime (hours:minutes), temperature, status, cycle count, health, and voltage

Note: Applies to SB900B battery only

RESTORE Restores bodypack to factory default settings
AUTO OFF Automatically turns off the bodypack after a selectable amount of time (5, 30, or 60 min.) while it is in power-save mode or when connected to a charger with the power on. To restore power to the bodypack, the power switch must be turned off and then on again.

Note: SB900B batteries charge fastest when the bodypack is off

RF Settings

The RADIO menu contains selectable GROUP and CHANNEL settings, which are used to manually synchronize the receiver with the transmitter.

The frequency and band are displayed below the group and channel settings for reference.

MixMode and Stereo Monitoring

The bodypack can operate in either of the following listening modes:

Stereo (default)

To operate in stereo mode, enter the menu and select AUDIO > MODE > STEREO .

In stereo mode, audio from channel 1 is heard on the left earphone, while audio from channel 2 is heard on the right earphone. Listening in stereo increases clarity and separation between the sources on each channel.

Adjusting Balance

To adjust the left/right balance, select AUDIO > BAL ST. Use the ▲▼ buttons to change the setting.


To operate in MixMode, enter the menu and select AUDIO > MODE > MIXMODE.

In MixMode, the blend between two monitoring mixes (an instrumental mix and a vocal mix, for example) is adjustable. The signal is mono, which means each mix is heard through both the left and right earphones.

Adjusting mix blend

To adjust the blend between channel 1 and channel 2, enter the menu and select AUDIO > BAL MX. Use the arrow buttons (▲▼) to make adjustments.

In this scenario, an instrumental mix is on channel 1 (left) and a vocal mix is on channel 2 (right):

To hear more of channel one (instruments), shift the balance towards the left.

To hear more of channel two (vocals), shift the balance towards the right.

Balance and Mix Adjustments from the Home Screen

To make quick adjustments to the stereo balance or MixMode blend, use the arrow buttons (▲▼) while in the home screen. If necessary, use the lock feature to prevent any accidental adjustments.

Important Tips for Care and Storage of Shure Rechargeable Batteries

Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.

  • Always store batteries and bodypacks at room temperature
  • Ideally, batteries should be charged to approximately 40% of capacity for long-term storage
  • During storage, check batteries every 6 months and recharge to 40% of capacity as needed
