Warning
USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.
ALWAYS USE A VOLUME LEVEL AS LOW AS POSSIBLE.
The Occupational Safety Health Administration (OSHA) has established the following guidelines for
maximum time exposure to sound pressure levels (SPL) before hearing damage occurs:
90 dB SPL @ 8 hours
95 dB SPL @ 4 hours
100 dB SPL @ 2 hours
105 dB SPL @ 1 hour
110 dB SPL @ 1/2 hour
115 dB SPL @ 15 minutes
Avoid exposure to 120 dB SPL or greater or irreversible ear damage may result.
(Note: It is difficult to measure the SPL present at the eardrum in live sound applications. The volume
present will be affected by the level setting of your PEM-1000R, the ambient stage sound from your
other instruments and speakers, and the quality of and fit of your in-ear speakers.)
Always avoid prolonged listening at excessive sound pressure levels. Use the following guidelines to use
this system safely:
1. Turn up the volume to your earphones only enough to hear properly. The PEM-1000 can provide a high
quality monitor mix at significantly lower decibel levels than floor monitors. Whenever possible, use
the system with the limiter in the PEM-1000R receiver ON.
2. Just as with any in-ear monitor system, The PEM-1000 works best when used exclusively by all
performers on stage (without any wedges or side monitors). The high sound pressure levels produced
by floor monitors (especially if the band plays loud) can bleed through the in-ear monitor ear-buds and,
in the worst cases, hinder their effectiveness. Experiment with your overall mix to get the maximum
benefit from your PEM-1000.
3. Turn down the volume immediately if you experience any pain or hearing discomfort or ringing in the
ears after use.
4. Have an audiologist check your hearing and ears regularly. If you experience any wax buildup in your
ears, do not use the system until an audiologist examines your ears.
5. Wipe the earphones with an antiseptic before and after use to avoid infection. Stop using the
earphones if they cause discomfort or infection.
