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.
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.
▇Applications

7
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.

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.
Rack Mounting
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:
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.

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.

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.
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.

10
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.
MONO/STEREO-MX LINE/AUX TRS IN
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.

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.
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".

11
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.
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.

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.

Stereo
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.

Right (Channel 2)
MixMode
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:

Troubleshooting
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

▇应用

63
带独立混音的多个发射机
当一组中多位演出者有不同监控要求时，可同时使用多个 PSM300 系
统通过每个发射机发送不同的混音。此设置要求可为每个发射机提供
两种监控器/辅助设备输出的混音器。
提示：为了在涉及多个发射机的应用中简化设置，舒尔提供 P3AC
天线和配电系统，仅从一个来源为多达四个 PSM 发射机供电并提
供射频。
路由至外部设备的信号（组合系统）
LOOP 输出将音频传递给外部设备，比如，其他个人监控系统、录音设备
或舞台监控器。LOOP 输出的信息与来自混音器的信号相同，均不受发
射机音量或输入敏感性（线路/辅助设备）设置影响。因此，在使用具备
一个或两个监控器/辅助设备的混音器时，LOOP 输出特别有用。
同时使用 PSM300 和扬声器：
当一些演出者使用 PSM300 无线系统，而其他演出者通过舞台上的扬声
器进行聆听时，可使用组合监控系统。
注意：如果使用无源舞台监控器，必须将 P3T 输出连接至扩音器。有
源（已扩音）扬声器可直接连接至 P3T 输出。
组合使用 PSM300 与其他无线监控系统
在两位演出者有其各自的无线监控系统（例如，一个舒尔 PSM300 系统
和一个第三方系统）的情况下，PSM300 可将源自混音器的信号传递至
第二个监控系统。
