18. Exposure to extremely high noise level may cause permanent hearing loss. Individual varies

considerably in susceptibility to noise-induced hearing loss, but nearly everyone will loss some hearing if exposed to sufficiently intense noise for a period of

time. The U.S. Government's Occupational Safety and

Health Administration (OSHA) have specified the permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent a permanent hearing loss if exposure is in excess of the limits set forth here.

AC-Power Sources

This set should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of electrical power supplied to your home, consult your dealer or local power company. For those sets designed to operate from battery power, or other sources, refer to the operating instructions.

SAFETY PRECAUTIONS

Selecting fine audio equipment such as the unit you've just purchased is only the first step to your musical enjoyment.

Now it's time to consider how you can maximize the fun and the safety of your new equipment. We want you to get the most out of your equipment by playing it at a safe level without affecting your hearing. Sound can be very harmful.

Over time your hearing "comfort level" adapts to higher volume of sound. What sounds "normal" can actually be loud and harmful to your hearing. Therefore, please guard against this by setting your equipment at a safe level before your hearing adapts. To establish a safe level, you can start your volume control at a low setting, then slowly increase the sound until you can hear it comfortably and clearly. If used wisely, your new sound equipment will provide you a pleasant experience in music. Since hearing damage from loud noise is often undetectable until it is too late, we recommend you avoid prolonged exposure to excessive noise. The following noises can be dangerous under constant exposure. Therefore, please be cautious with the dB level when playing your new equipment.

Decibel Level

120 dB

140 dB

Rock band concert in front of speakers, thunderclap

NOTE

The Mic Master Volume must be turn off before insert 1/4” microphone jack into mic inputs to protect the amplifier.

NOTE

The volume control is the same for the Rear microphone inputs (MIC 4 +

MIC 5) and the front microphone inputs (MIC 1 + MIC 2). The volume control for the front MIC 1 and rear MIC 4 has the same input terminal. For the same token, the volume control for the front MIC 2 and rear MIC 5 has the same input terminal. If you use the front and rear microphones at the same, these two microphones may have different output level. Therefore, we recommend you to adjust the output level of the microphones from the wireless receiver system in order to protect the system components.
