IMPORTANT SAFETY INSTRUCTIONS
WARNING: When using electrical products, basic cautions should always be followed, including the following:
1.Read these instructions.
2.Keep these instructions.
3.Heed all warnings.
4.Follow all instructions.
5.Do not use this apparatus near water.
6.Clean only with a dry cloth.
7.Do not block any of the ventilation openings. Install in accordance with manufacturer’s instructions.
8.Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat.
9.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 plug. The wide blade or third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10.Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point they exit from the apparatus.
11.Note for UK only: If the colors of the wires in the mains lead of this unit do not correspond with the terminals in your plug‚ proceed as follows:
a)The wire that is colored green and yellow must be connected to the terminal that is marked by the letter E‚ the earth symbol‚ colored green or colored green and yellow.
b)The wire that is colored blue must be connected to the terminal that is marked with the letter N or the color black.
c)The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red.
12.Only use attachments/accessories provided by the manufacturer.
13.Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a
cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
14.Unplug this apparatus during lightning storms or when unused for long periods of time.
15.Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
16.Never break off the ground pin. Write for our free booklet “Shock Hazard and Grounding.” Connect only to a power supply of the type marked on the unit adjacent to the power supply cord.
17.If this product is to be mounted in an equipment rack, rear support should be provided.
18.Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures:
Duration Per Day In Hours |
Sound Level dBA, Slow Response |
8 |
90 |
6 |
92 |
4 |
95 |

1 1⁄2 |
102 |
1 |
105 |

110 |
1⁄4 or less |
115 |
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if exposure is in excess of the limits as set forth above. 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 such as this amplification system be protected by hearing protectors while this unit is in operation.
