USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. USE
AS LOW A VOLUME AS POSSIBLE.
WARNING!
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 | 110 dB SPL at½ hour |
|---|---|
| 95 dB SPL at 4 hours | 115 dB SPL at 15 minutes |
| 100 dB SPL at 2 hours | 120 dB SPL – avoid or damage may occur |
| 105 dB SPL at 1 hour |
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
Personal Monitors, 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.
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 ear molds with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing great discomfort or infection.
IMPORTAINT SAFETY IINSTFLCTIONS !
- READ these instructions.
- KEEP these instructions.
- HEED all warnings.
- FOLLOW all instructions.
- DO NOT use this apparatus near water.
- CLEAN ONLY with dry cloth.
- DO NOT block any ventilation openings. Install in accordance with the manufacturer’s instructions.
- DO NOT install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat.
- DO NOT defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wider blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

Introduction
- EIA-standard metal materials half – rack transmitter chassis.
- Durable, ergonomic metal body Receiver with soft-touch controls.
- 16MHz Bandwidth, 640 Selectable UHF frequencies/ 32 Channels and True Diversity reception for interference-resistant operation and High-visibility white LCD information display
- PLL (Phase Lock Loop frequency control) design ensures transmission reliability, “Noise Lock” squelch effectively blocks stray RF.
- Designed to provide incredible audio quality and reliable performance for artists, broadcasters and other demanding audio environments.
Transmitter Installation and Connections
Installation
- For better operation the transmitter should be at least 3ft. (1m) above the ground and at least 3ft. away from a wall or metal surface to minimize reflections.
- Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles and neon lights, as well as away from large metal objects.
- Antenna are normally positioned 45° from vertical for best transmission.
- Keep open space between the receiver and transmitter for better reception.
- The transmitter should be at least 6ft. (2m) from the receiver.
Connections:
- The 12V, 500mA switching power supply is designed to operate properly from any AC power source without user adjustment. Simply connect the transmitter to a standard AC power outlet, using only an I EC-type input cordset approved for the country of use. Power to the unit is controlled by the front panel power switch.
- There are two audio inputs on the rear panel: 1/L and 2/R audio INPUTS. Suitable for an XLR balanced audio input connector or a balanced/unbalanced 1/4″ (6.3mm) input connector. The two audio inputs simultaneous feed from two different outputs. Use the appropriate shielded audio cable for connections between the transmitter and the output(s) of the mixer or other audio output equipment.
