This symbol indicates that there are important operating and maintenance instruc-
tions in the literature accompanying this unit.
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 pres-
sure 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 1/2hour
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 ear-
drum 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 pro-
vided 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. Ringingin the ears may indicate that the gain levels are too high. Try lowering the
gain levels.
3. Have yourears checked by anaudiologist onaregular basis. If youexperience
wax buildup in your ears, stop using the system until an audiologist has ex-
amined your ears.
4. Wipethe earphones with an antiseptic before and after use to avoid infections. Stop
using the earphones if they are causing great discomfort or infection.

Thank you for buying the P4R Receiver. The P4R is a component in the PSMR400 family of wireless
personal monitors. When used with a P4T Transmitter, it provides the many advantages of a wireless,
in-ear monitoring system, including:
SImproved Sound Quality - high fidelity without the risk of feedback,
SIncreased Mobility - your mix moves with you,
SPersonal Control - through volume adjustment and MixModeR.
For further information on the PSM 400 system, see the PSM 400 Wireless Personal Perfor-
mance Pack user’s guide, available on the world wide web at www.shure.com.

mum.
4. Set the P4R to the same reception channel as the P4T. See Changing Reception
Channelon page 6.
5. Check the LCD screen to see if RF is being received. See LCD Screen on
page 4.
6. Plug earphones into earphone output jack.
7. Insert earphones into your ears as instructed in the earphone’s user guide.
8. Increase the volume to a comfortable listening level.
WARNING:High volume levels may cause hearing damage!
9. Set the desired functions in the LCD screen. See LCD Screen on page 4, and Push-

1. RF:Indicates the P4R receiver is receiv-
ing a transmission. Always check for RF
reception prior to inserting earphones
into ears.
2. Battery Life Meter: Indicates the
approximate amount of voltage left in
the battery. These voltages translate
to time as follows:
HIGH: 4-8 hours of operation.
MEDIUM: 1-4 hours of operation.
LOW: less than 1 hours of operation.
NOTE: If no bars are present within the battery
life gauge, change the battery immediately.
Battery life depends on many variables, in-
cludingbattery type (brand), earphones used,
and receiver volume setting.
3. RECEPTION CHANNEL (FREQ):
The P4R receiver features 16 preset,
user-selectable channels (0–9 and
A–F). The receiver must be set to the
same channel as its transmitter.
4. MixMode (MIX): The receiver receives
the monitor mix in either MixMode (MIX
ON) or stereo (MIX OFF). See Mix-
Mode/Stereo Control on page 5.
NOTE: If the receiver is receiving only one sig-
nal, it will be in mono.
5. High Frequency Equalization (EQ):
Adds 6 dB at 10 KHZ for increased
treble response.
6. Limiter (LIM): The limiter provides
protection against loud signals.
WARNING! Turning the Limiter OFF defeats protection against hazardous
sound levels!

MIXMODE/STEREO
The P4R receiver receives two signals (1/L and 2/R) from the P4T transmitter. The P4R pro-
cesses these signals in either stereo or MixMode:

STEREO: In stereo, the signals remain separate so 1/L is heard through the left earphone and
2/R is heard through the right earphone. The balance knob on the receiver adjusts the balance
betweenthe left and right earphones.
MIXMODE: In MixMode, the signals are “mixed”in relation to one another using the balance
knob, blending into one signal. The mixed signal is sent to boththe left and right earphones.
Step One: The P4R re-
ceives TWO signals from
the P4T transmitter.
Step Two: Using the balance knob,
the user blends the two signals until
the correct mix is achieved.
Step Three: The P4R
sends the mixed signal
to both earphones.
Step Four: The user may
continue to adjust the blend
using the balance knob
throughout the performance.

MIXMODE IN APPLICATIONS
MixModeis most useful when two distinct mixes are provided to the P4T transmitter, such as a
bandmix and a vocal mix. MixMode combines these two signals into one monitor mix and allows
you to control this mix duringthe performance with the P4R receiver. For example, if the band
overpowersthe vocals in the mix, increase the level of the vocals and decrease the level of the
band by simply adjusting the balance knob.
