The LED slowly fades on/off in this mode and continues to display the color that represents the remaining battery life.
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 re
quires 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 simulta
neously 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 PA411 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.

Shure Incorporated
14/36
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 oth
ers 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 us
ing 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
Use the power adapter to connect the P3T to an AC power source.
Install 2 AA batteries in the bodypack receiver.
Attach the antenna to the BNC antenna connector on the P3T rear panel.
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:
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.
Make sure the P3T transmitter is OFF.
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:
Perform a scan on the receiver (see "Scanning for the Best Open Channel" for best practices).
Align the IR windows on the receiver and transmitter. The windows should be 6-11 cm apart.
Press the SYNC button on the transmitter while the blue RF LED on the receiver is flashing.
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:
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.
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
Set up the first transmitter and all associated receivers according to the appropriate sync procedure. Keep the transmit
ter and all receivers from this first system powered on when setting up additional systems.
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:
Press GROUP to scroll through group settings.
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 sig
nal-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.

Shure Incorporated
19/36
①Adjust 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.
②Adjust 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".

Operation
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.
①Mixer 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.
②Monitor/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.
③Wireless 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.
