Set Up And Operation - Shure P4T User Manual

Introduction
Thank you for buying the P4T Transmitter. The P4T is a component in the PSM400 family of wireless personal monitors. When used in conjunction with a P4R
Receiver, it provides the many advantages of an in–ear monitoring system, including:
This user's guide covers the use and features of the P4T Transmitter. For further instruction on the use of the PSM400 system, see the PSM400 system user's
guide, availaible on the web at www.shure.com.
P4T Transmitter Features
1. Local Earphone Output Jack (1/8 inch): Connects to E1 or E5
earphones.
2. Local Earphone Level Control: This knob adjusts the volume of
the local earphone jack's amplifier. Always listen at low levels.
3. Input Level LEDs: Two vertical strings of four LEDs display the
input level of the left and right input channels. The four LEDs on
the left displays the status of the signal from channel 1 and the
four LEDs on the right displays the status of the signal from
channel 2:

RED (top)
YELLOW (middle)
GREEN (bottom two)

Set Up and Operation

Follow these directions to set up the P4T for operation.
1. Plug the power cord into the P4T's 12 VDC locking power connec-
tor. Plug the other end of the power cord into a wall outlet.
2. Connect line level outputs of an audio source into the audio
inputs of the P4T transmitter. Use both of the P4T's input jacks
for a two-channel source. Use either input jack for a mono
source. The P4T Transmitter will transmit in MixMode/Stereo if
both inputs are used, but will automatically transmit in mono if
only one input is used.
NOTE: All inputs are phantom power protected up to 50 VDC.

4. Frequency Select LED: This indicates which of the 16 Chan-
nels (0 - 9 and A - F) is selected.
5. Frequency Select Button: This recessed button allows the
transmission channel to be changed. To use, hold down the
button until the desired channel number is displayed in the
LED. Release the button and the number will flash. Quickly
push and release the button again to confirm changes.
6. Front-Mounted Antenna: The units antenna is permanently
attached and break-resistant.
7. Loop Out Jacks: Two 1/4" TRS jacks allow the audio signal to
pass through the transmitter to other devices, such as other
transmitters, tape recorders, or amplifiers.
8. Input Jacks: Two 1/4" TRS Switching Jacks for line level audio
inputs. If only one input is used, the signal will be routed to both
sides of the modulator for Mono operation. If both Jacks are
used, the signals will be transmitted in Stereo/MixMode.
9. 12VDC Locking Connector: Input for PS40 Power Cord.
3. Select an operating frequency using the Frequency Select Button.
The selected frequency will be displayed in the LED.
IMPORTANT: Never set more than ONE transmitter to the
same operating frequency.
4. Once audio is being transmitted by the P4T, observe the Input
Level LEDs. If the input signal is consistently causing the red
LED to illuminate, decrease the output level of the audio source
until the red LED only flickers occasionally.
5. Set up the P4R receiver as directed in the P4R user's guide,
making sure that the frequency selected on the receiver
matches the frequency selected on the transmitter.
