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