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 1/2 hour
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 earpieces 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 ear molds with an antiseptic before and after use to avoid infections. Stop using the ear molds if they are
causing great discomfort or infection.

IMPORTANT: The Limiter is designed to respond to and limit the loudness of unexpectedly
high signals. It is not designed to prevent long term exposure to high SPL levels. It is
designed for use with the E-Series earpieces, so the maximum limited SPL may be
different with other earpieces. We recommend that you always use the built-in limiter
provided with this system. However, a limiter defeat switch has been provided for those who
would prefer to use an external limiter product.
Selecting Frequencies
The Shure PSM700 Personal Stereo Monitor System is frequency-agile, with two
groups of 16 channels for a total of 32 different possibe operating frequencies. The P7T
transmitter and the P7R receiver each has a switch for selecting between the two groups,
and a rotary dial for selecting the channel. Use the supplied screwdriver for adjusting the
rotary dial.
CHANNEL
GROUP
1. Set the GROUP switch on the P7T transmitter to the desired group (group 1 or 2).

INSTALLATION AND APPLICATIONS
The flexible design of the PSM700 Personal Stereo Monitor System makes configuring a
monitor mix very simple. In addition, the unique MixMode circuitry enables you to customize
your own individual mix in a multiple mix environment. To help you install the PSM700 into
your sound system, the tables and diagrams in this section describe three distinct modes of
operating the system. Although the examples show only single system setups, you can
configure multiple wireless systems in a setup. Some multiple mix setups are detailed in the
LOOP Applications section of this chapter.
Operating Modes
For optimum performance, The P7T requires a LINE level input signal.
Stereo Control
MixMode Control
Mono Control
Used for conventional Stereo monitor mixes.
Transmitter Stereo/MixMode setting
Receiver Stereo setting
Balance Dial Varies stereo left/right image
Used for creating an individual mix between two distinct monitor sends.
Transmitter Stereo/MixMode setting
Receiver MixMode setting
Balance Dial Varies levels between mixes
Used when only one (mono) monitor mix is available.
Transmitter Mono setting
Receiver Stereo setting
Balance Dial Varies the right/left volume control
NOTE: For the best results, the input signal must be a LINE level signal. For
consistency throughout the following diagrams, a mixing console is shown as the source
supplying the audio signal to the P7T transmitter. However, any balanced or unbalanced
send that outputs a LINE level should drive the P7T. Some devices that would work are CD
players, DAT machines, direct injection boxes, and microphone preamplifiers.

LOOP Applications
The LOOP OUT L (left) and R (right) outputs allow the signal going through the P7T to be
run to other devices. The LOOP feature of the P7T can be used for any number of
applications. Shown here are only a few examples of how it can be used.
NOTE: The LOOP connectors act as either inputs or outputs. They can be
used as outputs when the LEFT and RIGHT INPUT connectors are used for
input. However, LOOP connectors can also act as inputs when connected
directly to the outputs of a mixer. When the LOOP connectors are used as
inputs, the LEFT and RIGHT INPUT connectors act as outputs. These
diagrams show the LOOP connectors being used as outputs. Also, the
input pad does not affect the level of the LOOP signals.
Running Multiple PSM Wireless Systems Under Stereo Control
The LOOP OUT connectors can be used to send the same monitor stereo signals to
multiple P7T wireless transmitters. This will free up busses on the mixing console, allowing
you more freedom with your audio system. Simply connect a P7T to the mixing console as
described in Stereo Control, then run 1/4-in to 1/4-in from the L/R LOOP connectors of the first
unit to the LEFT/RIGHT Input connectors of the next unit. Connect subsequent unit in the
same way.

Running Multiple PSM Wireless Systems Under MixMode Control
A main mono monitor mix can be sent to multiple P7T transmitters, then independent
monitor mixes can be sent to the second channel of each. This will allow an entire band to
hear the same monitor mix, while giving each individual player a separate mix of their own.
Each player can then use the balance control to adjust the levels between their own mix and
the main mono monitor mix.

Voltage Selection
P7T and EP7T transmitters can be internally modified to
operate at either 120 Vac or 230 Vac.
WARNING
Voltages in this equipment are hazardous to life.
No user-serviceable parts inside. Refer all
servicing to qualified service personnel.
The safety certifications of the P7T do not apply
when the operating voltage is changed from the
factory setting.

4.
To change the operating voltage, follow these steps.
Disconnect the P7T from the ac power source.
Remove the eight Phillips head screws securing the top
cover.
Locate Voltage Selector switch SW4 adjacent to power
transformer T1 and, using a screwdriver, turn the center
rotor to the desired position:
For 120 V operation, turn it to the 115 V position.
For 230 V operation, turn it to the 230 V position.
Locate fuse and remove it. Replace it with the proper fuse:
For 120 V operation, use a 160 mA, 250 V, slow-blow fuse.
For 230 V operation, use a 80 mA, 250 V, time delay fuse.

5. Replace the power cord with the proper power cord:
For 120 V operation, use an IEC appliance connector on
the equipment end and a mains connector suitable for 115
V operation on the other.* (Shure part #95A8389.)
For 230 V operation, use an IEC appliance connector on
the equipment end and a CEE 7/7 (“Schuko”) mains
connector on the other.* (Shure part #95A8247.)
*For systems requiring other mains connectors, obtain a power cord with an
IEC 320 type mating connector for connection to the P7T, and an appropriate
plug on the other end for connection to the mains. The supplied cord uses
Harmonized IEC Cordage with color coding as follows: Brown = Line, Blue =
Neutral, Green/Yellow = Ground.
