System Applications

Refer to the following PSM300 system scenarios prior to installation. Understanding the configuration options before setting up helps to identify signal routing requirements and plan for future expansion. Specific information on how to set up the PSM300 system and create mixes for monitoring can be found in the "System Setup and Configuration" and "Operation" sections of this user guide.

Single System for an Individual Performer

This configuration provides in-ear monitoring in a solo performance, or in a group performance in which only one person requires wireless monitoring. This system can be expanded for multiple performers by using additional P3R bodypack receivers tuned to the same transmitter.

Single Transmitter with Multiple Receivers

Multiple performers can monitor audio from the same transmitter and still adjust the signal at their bodypack to personalize the mix. Simply tune each bodypack to the same frequency as the transmitter and use the MixMode knob to adjust the mix.

MixMode or Stereo Operation:

Each performer has the option of setting their bodypack to MixMode or Stereo when the transmitter is set to Stereo-MX. When the bodypack is powered on, it is set to stereo by default. To operate in MixMode, hold the GROUP button when turning the power on. For information on these modes, see "MixMode and Stereo Monitoring".

Multiple Transmitters with Separate Mixes

When several performers in a group have different monitoring requirements, multiple PSM300 systems may be used simultaneously to send different mixes through each transmitter. This setup requires a mixer with two monitor/auxiliary outputs for each transmitter.

Tip: To simplify setup in applications that involve multiple transmitters, Shure offers the P3AC antenna and power distribution system, which supplies up to four PSM transmitters with power and RF from a single source.

Signal Routing to External Devices (Combination Systems)

The LOOP outputs pass audio to an external device, such as other personal monitoring systems, recording devices, or stage monitors. The signal at the LOOP outputs is identical to the signal coming from the mixer, and is not affected by the transmitter volume or input sensitivity (line/aux) settings. This makes the LOOP outputs particularly useful when using a mixer that has one or two monitor/auxiliary sends.

Using the PSM300 simultaneously with Loudspeakers:

A combination monitoring system can be used, where some of the performers are using the PSM300 wireless system and others are listening through loudspeakers on stage.

Note: If using passive stage monitors, the P3T outputs must be connected to an amplifier. Active (amplified) speakers can be connected directly to the P3T outputs.

Using the PSM300 Combined with Other Wireless Monitoring Systems

In a scenario where two performers have their own wireless monitoring systems (one Shure PSM300 system and one third-party system, for example), the PSM300 can pass the signal from the mixer on to the second monitoring system.

System Setup and Configuration

Rack Mounting

The P3T Transmitter can be mounted in a standard 19-inch rack. Up to two units can be mounted in a single rack space. If using multiple P3T transmitters, the Shure PA411 Antenna Combiner system can be used to consolidate and distribute all RF and power for up to four transmitters.

Note: Always use both straddle bars when mounting two units.

Power, Audio, and RF Connections

  1. Use the power adapter to connect the P3T to an AC power source.
  2. Install 2 AA batteries in the bodypack receiver.
  3. Attach the antenna to the BNC antenna connector on the P3T rear panel.
  4. Connect the mixer or audio source to the P3T audio inputs using ¼ inch balanced cables.

    Important: When connecting to only one transmitter input, use the LEFT/CH1 input. Set the transmitter to MONO to hear audio on both channels of the receiver.

Scanning for the Best Open Channel

Follow these steps to scan the RF environment and find the best available frequency for operation:

  1. Turn on the bodypack receiver and any potential sources of interference, including wireless systems, computers, audio equipment, cellular phones, LED panels, and other electronic devices that will be in use during a performance.
  2. Make sure the P3T transmitter is OFF.
  3. Position the receiver in the performance area and press SCAN to survey the available channels within the current group setting.

    If using several PSM300 systems or operating in a location with a high volume of wireless devices, perform a group scan first, followed by a channel scan:

    Group Scan: Press and hold the SCAN button on the receiver.

    Channel Scan: Press the SCAN button on the receiver.

Creating a Wireless Connection Between Receivers and Transmitters (Sync)

To pass audio from the transmitter to the receiver, both must be tuned to the same frequency. The easiest way to configure the system is to use the automatic sync feature. This transfers group and channel settings with a press of a button. Based on your system configuration, use one of the following processes to sync the components:

Align the IR windows to sync the receiver and transmitter

Pressing the SYNC button transfers group/channel data

Single Transmitter and Receiver

The following sync procedure should be used with a setup that consists of a single transmitter and receiver, unless a group/channel setting has been assigned prior to a performance.

Sync from receiver to transmitter:

  1. Perform a scan on the receiver (see "Scanning for the Best Open Channel" for best practices).
  2. Align the IR windows on the receiver and transmitter. The windows should be 6-11 cm apart.
  3. Press the SYNC button on the transmitter while the blue RF LED on the receiver is flashing.
  4. The Transmitter displays SYNC when the sync is successful. The arrow between Rx (receiver) and Tx (transmitter) shows the direction of the sync.

    Note: When the RF LED on the receiver is flashing after performing a scan, the receiver sends its frequency setting to the transmitter. After it stops flashing, pressing SYNC sends the frequency setting from the transmitter to the receiver.

Single Transmitter and Multiple Receivers

The following sync procedure should be used with a setup that consists of a single transmitter with multiple receivers, or if a specific group/channel setting has been assigned to the transmitter prior to a performance.

Sync from transmitter to receivers:

  1. Sync the first receiver to the transmitter using the sync procedure for a single receiver. Performing a scan and using the resulting group and channel from the receiver is recommended.
  2. Set additional receivers to the transmitter frequency (one at a time) using IR sync:
    • Align the IR windows on the receiver and transmitter and press SYNC.
    • The receiver LED should not be flashing when pressing SYNC.

    Note: Receivers can also be manually tuned to the transmitter if an IR sync is not practical.

Multiple Transmitters and Multiple Receivers

  1. Set up the first transmitter and all associated receivers according to the appropriate sync procedure. Keep the transmitter and all receivers from this first system powered on when setting up additional systems.
  2. Set up each additional system using the appropriate sync process. Always leave each new system on before setting up an additional one.

Manual Selection

If frequencies have been planned ahead of time, the group and channel can be set manually without performing a scan. Refer to the frequency table at the end of this user guide to identify frequencies for each group/channel setting.

To select group/channel settings on the receiver and transmitter:

  1. Press GROUP to scroll through group settings.
  2. Press CHANNEL to scroll through channel settings within the selected group.

Adjusting Gain and Listening Volume

For the best audio quality, start by adjusting the levels from the mixer or audio source, and then adjust levels through the PSM300 system. This approach corresponds to the way that the audio signal flows through the system, and maximizes the signal-to-noise ratio.

Before you begin: verify all signal routing and gain settings at the mixer or source prior to adjusting any levels from the PSM300 system. If the sound is distorted or faint when it enters the P3T transmitter, there is likely an issue elsewhere in the signal chain that needs to be resolved.

① Adjust Transmitter Levels:

Input Sensitivity

Select the setting that matches the input source:

Line (+4 dBu) Use with mixers or other professional audio devices that send line-level signals.
Aux (-10 dBV) Use when connecting consumer audio devices such as portable audio players or computers.

Note: When using consumer audio devices, the output volume of the device should typically be adjusted as close to the maximum setting as possible without distorting or clipping at the output of the device. This maximizes the signal-to-noise ratio.

Input Level

Adjust the level so that average levels on the audio meter reach approximately 75% of the full range. The highest levels should occasionally hit the 0dB indicator on the audio input meter, without reaching the OL (overload) indicator.

Tip: If a sound check before the performance is possible, everyone should play at the loudest anticipated volume so that attenuation is not required during the performance.

② Adjust Receiver Volume:

After levels are established at the mixer and transmitter, use the headphone volume control on the bodypack receiver to adjust overall listening volume. For information on adjusting the left/right balance or customizing the mix blend, see "MixMode and Stereo Monitoring".


Creating Monitor Mixes

The mix that performers hear on stage is usually different than the mix heard by the audience. In live sound applications, the engineer creates a separate mix to send to the performer by routing the input signals to specified mixer outputs, usually called Monitor or Auxiliary outputs.

The following scenario demonstrates a generic signal path for monitoring mixes, and may not reflect the routing for all mixer types. Consult the user guide for your mixer for detailed signal routing options.

① Mixer Channel

Each mixer channel controls audio processing and routing for a single audio source. In this example, a vocal microphone is plugged into the mixer channel.

② Monitor/Auxiliary Sends

Adjust the signal levels to send to the monitor/auxiliary outputs, each of which corresponds to a separate monitoring mix. Each of these mixes are sent to separate channels on the P3T transmitter.

Note: The channel faders on most mixers do not affect the volume of the monitor/auxiliary sends.

③ Wireless Transmission

Each monitoring mix is transmitted on a separate channel to the P3R receiver. The MixMode knob on the bodypack adjusts the blend between the audio from channel 1 and channel 2.

MixMode and Stereo Monitoring

The receiver can operate in stereo or MixMode when the transmitter is set to STEREO-MX. In applications that involve multiple bodypack receivers tuned to a single transmitter, some bodypacks can operate in stereo, while others operate in MixMode.

Selecting the Mode

Stereo: The receiver is set to stereo mode by default. To switch from MixMode to stereo, simply turn the receiver off and it will return to stereo mode when powered back on.

MixMode: Press and hold the GROUP button on the bodypack receiver while turning the power on. The MixMode indicator light on the receiver display turns on to confirm the setting. The receiver will return to stereo mode after it has been powered off.


Audio from channel 1 is heard on the left earphone, while audio from channel 2 is heard on the right earphone. Listening in stereo mode increases separation between the sources on each channel, which can improve clarity when many sources are being monitored. The MixMode knob on the bodypack adjusts left/right balance when operating in stereo mode.


MixMode allows performers to adjust the blend between two monitoring mixes (an instrumental mix and a vocal mix, for example). When using MixMode:

  • Each mix is heard through both the left and right earphones
  • The MixMode knob adjusts the volume blend between the two monitor mixes (channel 1 and channel 2)
  • Each bodypack receiver can dial in a unique blend to meet the monitoring needs of each performer

Adjusting mix levels

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

To hear more of channel one, turn the MixMode knob to the left.

To hear more of channel two, turn the MixMode knob to the right.

When to Use the Mono Setting

In some cases, only a single input on the transmitter is used (if the mixer only features a single monitor/auxiliary output, for example). To ensure that audio is heard on both the left and right earphones:

  • Use the LEFT/CH1 input on the transmitter
  • Set the transmitter to MONO

Note: When the transmitter is set to mono operation, the MixMode knob will not affect the sound.


Problem Solution
Distorted Audio
  • Check the volume levels at the P3T transmitter and verify that the meter is not reaching the overload indicator
  • Check levels going in and out of the mixer. If audio is distorting anywhere in the signal chain, it will be distorted even if the PSM300 system is not overloading.
  • Make sure batteries in the receiver are fresh
  • Verify that the cables are 1/4 inch balanced. If an unbalanced instrument or speaker cable is used, it may introduce noise.

    Tip: To tell the difference, look at the connectors on the cable. The metal connector on a balanced cable has two plastic rings that divide it into three separate sections (tip, ring, sleeve). An unbalanced cable only has a single plastic ring that divides the metal portion into two sections (tip, sleeve).

  • Check that all cables are plugged all the way into the mixer and the P3T inputs. Sometimes, if a cable is not fully inserted, the signal will be faint and distorted.
  • Make sure you are using the line-level outputs from the mixer. If you have a powered mixer, do not use the main speaker outputs, as they are amplified signals and will overload the P3T inputs.
No sound from receiver
  • Make sure the transmitter and receiver are linked to the same group and channel
  • Verify levels are registering at the transmitter and that the volume is turned up on the receiver
  • Check that the receiver is on and that the headphones are properly connected to the receiver
Turning the MixMode knob does not affect the sound
  • The Stereo-MX/Mono switch on the rear panel of the P3T may be switched to mono. For the MixMode knob to work, the transmitter must be set to Stereo-MX.
  • Verify that the signals going from the mixer to the transmitter are not identical
  • Check that the bodypack is set to MixMode
Low audio output at the receiver
  • Check headphone connection and volume level
  • If only sending a single channel into the P3T transmitter, check it the MixMode knob isn't turned towards a silent channel. If using one channel, set the P3T transmitter to mono mode.
Audio or RF drops out
  • Perform a scan to ensure the receiver is on a clear (available) frequency
  • Make sure there is a line-of-sight path between the transmitter antenna and the bodypack receivers
  • Verify that other wireless devices that are being monitored, such as wireless microphones, are not experiencing RF dropouts
  • If using an antenna other than the one included with the system, make sure it is designed to operate in the correct frequency range
IR sync failure Verify distance between receiver and transmitter is between 6-11 cm
