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 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 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:
• Turn up the volume control only far enough to hear properly.
• Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.
• 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.
• 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.

P4M PERSONAL MONITOR MIXER
Features
MIC/LINE INPUT Jacks: Accommodate both XLR and 1/4"
connectors at mic or line levels. They are electronically bal-
anced.
Signal/Clip LEDs: Color indicates the signal status of the cor-
responding MIC/LINE input:
CONCENTRIC LEVEL/PAN Knobs: The inner knob controls
the input level; the outer ring pans the input signal between
the 1/L and 2/R mix outputs.
MIX OUT Output Jacks: 1/4" TRS jacks provide the line level
mix created with the CONCENTRIC LEVEL/PAN knobs.
AUX IN Inputs: Signals from the two 1/4" TRS input jacks are
combined with the mix created by the CONCENTRIC
LEVEL/PAN knobs. Front panel settings do not affect these
jacks.
DC IN Locking Connector: Plug the PS40 AC adaptor into
this connector.
DC OUT Locking Connector: Powers a P4T Transmitter or
another P4M Mixer. A DC jumper cable is provided with the
P4M.
NOTE: A PS40 can only power two Shure devices.
SPLIT OUTPUT Jacks: Each male XLR output provides a
duplicate of its corresponding MIC/LINE input. Front panel
settings have no effect on split outputs.

ENGLISH
Using the P4M Personal Monitor Mixer
Once the basic set up is complete, use the P4M Personal Monitor Mixer to create a custom mix:
Mix the signal from each audio input using the corresponding
CONCENTRIC LEVEL/PAN knobs:
OUTER RING: Use this to pan the signal to the left or right
channel of the stereo mix.
INNER KNOB: Use this to control the level of the audio input.
Observe the Signal/Clip LEDs next to each CONCENTRIC
LEVEL/PAN knob.
NOTE: Decrease the level of an input if the corresponding
signal/clip LED is consistently red. If the level is
decreased all the way and the LED remains red, the level
of the input from the previous device in the audio chain is
too high and should be decreased.
Up to two additional line-level audio sources (such as other
mixers, a click track or a digital sequencer) may be added via
the AUX IN inputs. These signals go directly to the MIX OUT
outputs and are not affected by the CONCENTRIC
LEVEL/PAN knobs.
To pass an unaltered signal through the P4M, use the corre-
sponding SPLIT OUTPUT.
NOTE: Although the P4M does not provide phantom
power for condenser microphones, the SPLIT OUTPUTS
can pass phantom power from a phantom power supply
to a microphone connected to the corresponding input
jack.
CAUTION: Use a “direct box” when connecting guitars,
keyboards, and other instruments to a mixing console
through the P4M Mixer. The phantom power that mixing
consoles provide for microphones can damage other in-
struments. Connect the instrument to the direct box then
connect the direct box to the P4M Mixer input.

READING THE LCD SCREEN
The LCD screen displays the status of each function, as follows:
Input Level Meter: 3-segment input level meter displays level
of incoming signal. Always check for clipping prior to inserting
earphones into ears.
Battery Life Meter: Indicates the amount of voltage left in the
battery. If no indicators are present, change the battery as
soon as possible.
NOTE: Battery life depends on many variables, including
battery type (brand), earphones used, and volume
setting.
Input Attenuation: Displays the sensitivity of the bodypack's
input. Use “0 dB” attenuation for low levels (-10 dBu), and use
“-15 dB” attenuation for higher levels (+4 dBV).
MixMode (MIX): Allows the user to receive the monitor mix in
either MixMode (MIX ON) or Stereo (MIX OFF). If the body-
pack is receiving only one signal, use MIX ON. See Mono,
Stereo and MixMode Control on 7.
High Frequency Equalization (EQ): Adds 6 dB at 10 kHz for
improved treble response.
Limiter (LIM): Activates and deactivates an internal limiter
which provides protection against loud signals.
USING THE BODYPACK FEATURES
1. Push either the SCROLL or SELECT button to activate the
LCD screen.
2. Push and hold the SCROLL button until the desired function
(0/-15, MIX, EQ, or LIM) is underscored.
3. Push the SELECT button to toggle the function ON or OFF. A
function is ON when a dot appears to the right of the function
symbol.
4. Push the SCROLL button to activate the change.
LOCKING THE DISPLAY

2. Hold down the SCROLL and SELECT buttons simultaneously
for five seconds (see Figure 2 [A]). The display will show two
dashed lines to signify that lock out is engaged
(see Figure 2 [B]).
NOTE: When lock-out is engaged, the SCROLL and
SELECT buttons will still light the LCD screen, but will not
change the status of any of the functions.
3. To unlock the display, hold the SCROLL and SELECT buttons
simultaneously for five seconds until the LCD returns to a
numeric display.

MONO, STEREO AND MIXMODE CONTROL
The Hardwired Personal Performance Pack provides simple configuration of a monitor mix and enables the user to customize an indi-
vidual mix in a multiple mix environment. Three sound processing modes are available: mono, stereo, and MixMode.
FIGURE 3
Mono: The bodypack receives one signal from the mixer and sends that signal to both earphones. Adjust the balance knob all the way
toward the side that contains the mono signal. For mono signals, use MixMode (MIX ON).
Stereo: The bodypack receives two signals (L and R) from the mixer and sends the signals to the left and right earphones, respectively.
The balance knob adjusts the balance between the left and right earphones. For stereo signals, use the MIX OFF setting.
MixMode: Allows the performer to easily adjust the monitor mix during the performance. In MixMode, the bodypack receives two sig-
nals, such as a band mix and a vocal mix. The balance knob adjusts the mix of these two signals. The mixed signal is sent to both the
left and right earphones. For example, if the band is overpowering the vocals in the mix, the vocal levels can be increased and the band
mix level decreased by simply adjusting the balance knob (see Figure 4). For MixMode operation, use MIX ON.
