It is diffi cult to measure the exact Sound Pressure Levels (SPL) present at the ear-
drum in live applications. In addition to the volume setting on this Personal Monitor
unit, the SPL in the ear is affected by ambient sound from fl oor wedges or other
devices. The isolation provided by the fi t of quality earphones is also an important
factor in determining the SPL in the ear.
Follow these guidelines in the use of this product to protect your ears from damage:
1. Turn up the volume only to the point where hearing is comfortable.
2. Ringing in the ears may indicate that the levels are too high. Lower the volume
level.
3. Have your ears checked by an audiologist on a regular basis.
4. ALWAYS START WITH THE VOLUME AT 0 OR OFF THEN GRADUALLY
TURN IT UP TO A COMFORTABLE LEVEL!

INTRODUCTION
Thank you for your purchase of the PM57 Headphone Tap. The
PM57 is for connecting headphones to a speaker line. The 1/4”
Mono/stereo loop jacks are for cascading more boxes in series.
There are two headphone jacks and volume control. The Head-
phone Tap uses the speaker line signal for power, therefore
requires no batteries or external power.
ALWAYS SET THE ATTENUATION SWITCH TO THE PROPER
SETTING FOR YOUR INTENDED USE BEFORE CONNECTING
ANYTHING TO THE PM57 (INPUTS, OUTPUTS AND LOOPS).
THIS IS VERY IMPORTANT FOR YOUR SAFETY, THE SAFETY
OF THE PM57, AND ALL OTHER EQUIPMENT YOU WILL BE
USING WITH THE PM57!!!!!!!!!
