control. The Headphone Tap uses the speaker line signal for 

power, therefore requires no batteries or external power.

10 WATT AMPLIFIER TO FUNCTION PROPERLY.

MONO/STEREO Switch: Selects between a Mono or Stereo 

input mode.

POWER AMP LOOP: Two paralleled 1/4” stereo TRS jacks,

ing to a speaker or other input device.

VOLUME: Controls the level of the signal to the headphones.

HEADPHONES: Two 1/4” stereo TRS jacks for connection to 

stereo headphones.

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 this 

Personal Monitor unit, 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.

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. If you ex-

perience wax buildup in your ears, stop using the system until an audiolo-

gist has examined your ears.

4. 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.
