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.
PSM300 Transmitter P3T
sync
Sync from transmitter to receivers:
1. Sync the first receiver to the transmitter using the sync proce-
dure for a single receiver. Performing a scan and using the re-
sulting group and channel from the receiver is recommended.
2. Set additional receivers to the transmitter fre-
quency (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 set-
tings 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.
MONO/STEREO-MX
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 head-
phone 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".
