WARNING!
USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.
USE AS LOW A VOLUME AS POSSIBLE.
In order to use this system safely, avoid prolonged listening at excessive sound pressure levels. Please use the following guidelines
established by the Occupational Safety Health Administration (OSHA) on maximum time exposure to sound pressure levels before
hearing damage occurs.
90 dB SPL at 8 hours
95 dB SPL at 4 hours
100 dB SPL at 2 hours
105 dB SPL at 1 hour
110 dB SPL at
115 dB SPL at 15 minutes
120 dB SPL - avoid or damage may occur
It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In addition to the volume
setting on the PSM, the SPL in the ear is affected by ambient sound from floor wedges or other devices. The isolation provided by
the fit of quality earphones is also an important factor in determining the SPL in the ear.

Here are some general tips to follow in the use of this product to protect your ears from damage:
1. Turn up the volume control only far enough to hear properly.
2. Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.
3. Have your ears checked by an audiologist on a regular basis. If you experience wax buildup in your ears, stop using the system
until an audiologist has examined your ears.
4. Wipe the earphones with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing
great discomfort or infection.

INTRODUCTION
Thank you for buying the P4T Transmitter. The P4T is a component in the PSM® 400 family of wireless personal monitors. When used
with a P4R Receiver, it provides the many advantages of an in-ear monitoring system, including:
•
Improved Sound Quality
•
Increased Mobility
•
Personal Control
- through volume adjustment and MixMode®.
- high fidelity without the risk of feedback,
- your mix moves with you,
For further information on the PSM 400 system, see the PSM 400 Wireless Personal Performance Pack User's Guide, available on the
web at www.shure.com.

TRANSMITTER BACK PANEL
1. Local Earphone Output Jack (1/8 inch): Connects to 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 display the status of the signal from channel 1 and the four LEDs on the
right display the status of the signal from channel 2:
LED Signal Status
RED (top) Limiter Active
YELLOW (middle) Nominal Level
GREEN (bottom two) Signal Present
SET UP AND OPERATION
Follow these directions to set up the transmitter for operation.
1. Plug the power cord into the transmitter's DC INPUT power connector.
Plug the other end of the power cord into a wall outlet.
2. Attach the antenna to the ANTENNA OUT BNC connector.
3. Connect line level outputs of an audio source into the audio INPUTS
of the transmitter. Use both of the input jacks for a two-channel
source. Use either input jack for a mono source. The P4T transmits in
MixMode/stereo if both inputs are used, but automatically transmits in
mono if only one input is used.
NOTE: All inputs are phantom power protected up to 50 VDC.
4. Select an operating frequency using the Frequency Select Button.
Push the button repeatedly until the LED displays the desired chan-
PA715 ANTENNA
4. Transmission Frequency LED: This indicates which of the 16 chan-
nels (0-9 or A-F) is transmitting.
5. Frequency Select Button: This recessed button changes the trans-
mission channel. (Use a 1/4" plug to press this button.)
6. Antenna Connector 50 Ω, BNC type: This connects to the antenna
to transmit UHF signals to the receiver.
7. LOOP OUT Jacks: Two 1/4" TRS jacks allow the audio signal to pass
through the transmitter to other devices, including other transmitters,
tape recorders, or amplifiers.
8. INPUT Jacks: Two 1/4" TRS switching jacks are line level audio
inputs.
9. DC INPUT Connector: Input for PS40 power cord.
nel. The display flashes. Push and hold the button until the flashing
stops to confirm the change (use a 1/4" plug to press the button).
IMPORTANT: Never set more than ONE transmitter to the
same operating frequency.
5. Once the P4T transmits audio, observe the input level LEDs. If the
LEDs consistently illuminate red, decrease the output level of the
audio source until the red LEDs flicker occasionally.
6. Set up the P4R receiver as directed in the P4R user's guide. Make
sure that the frequency selected on the receiver matches the frequency selected on the transmitter.

LOOP APPLICATIONS
The LOOP OUT 1/L and 2/R outputs route the transmitter's incoming signal to other devices. Use the loop feature of the transmitter in
any number of applications, such as the following:
P4T Transmitter (back panel)
P4R
MIXER
Floor Monitor Amplifier
Operating Floor Monitors Through a P4T Transmitter: Send an audio signal through the LOOP connectors to a floor monitor amplifier.
In this set up, the receiver and the onstage monitors reproduce the same audio.

Operating Multiple PSM Wireless Systems Under MixMode Control: Send a band mix from a mixer to a P4T transmitter, then send
the band mix on to other transmitters using the P4T's LOOP OUT feature. Also send independent monitor mixes or direct outputs to the
second channel of each transmitter. The entire band receives the same band mix, while each individual player also hears a solo mix of
their own. Use the MixMode control on the P4R receiver to adjust the level between the solo mix and the band mix.

RACK MOUNTING THE P4T
The P4T features a 1/2-rack chassis specially designed for sturdiness. This eliminates the sagging and bending found in most 1/2-rack
designs. The brackets and straddle bars ensure that the units will be installed securely.
WARNING: Do not torque the screws too tightly, or the chassis may be damaged.
SINGLE UNIT DUAL-MOUNTED UNITS
MOUNTING IN AN EQUIPMENT RACK
NOTE: Be sure to use both straddle bars when installing dual units.
FRONT MOUNTING THE ANTENNA
The P4T transmitter comes equipped so the antenna can be front-mounted. Front-mounting prevents antenna cables from becoming entangled and greatly minimizes RF interference from other cables. When a unit is located in a rack, antennas should be either front- or
remote-mounted.
1. Insert the bulkhead adapter
through either hole of the mounting bracket and secure it from the
back using the supplied hardware.
2. Connect the transmitter antenna
output to the bulkhead adapter
with the supplied RF cable.
NOTE: The PA715 antenna, which comes supplied with the P4T, cannot be remote mounted. Use a PA705 antenna for remote mounting.
3. Install the antenna on the
bulkhead adapter.
