User manual YAMAHA BR12

[. . . ] - Add weight such as sand bags around the stand legs to prevent them from falling over. - Remove the speakers from the stands before moving the stands or adjusting their height. - Limit the number of people around the placed stand. · When transporting or moving the device, always use two or more people. Attempting to lift the device by yourself may damage your back, result in other injury, or cause damage to the device itself. [. . . ] If you experience any discomfort or ringing in the ears, or suspect an hearing loss, you should consult an audiologist. Special Notice Protective Circuit (poly switch) All full-range loudspeakers are fitted with a self-resetting poly switch that protects the high-frequency driver from damage caused by excessive power. If a loudspeaker cabinet loses high-frequency output, immediately remove power from the unit and wait for two to three minutes. This should be long enough to allow the poly switch to reset. Reapply power and check the performance of the high-frequency driver before continuing, with the power reduced to a level that does not cause the poly switch to interrupt the signal. · Illustrations in this manual are for explanatory purposes only, and may not match the actual appearance of the product during operation. · Company names and product names used in this Owner's Manual are trademarks or registered trademarks of their respective owners. Yamaha cannot be held responsible for damage caused by improper use or modifications to the device. 3 Connecting the Speakers Full-range Connection Each speaker features two input / parallel connectors -- two 1/4" phone jacks. Use one phone jack to receive input from your sound system / power amplifier. The other phone jack can be used to parallel-connect an additional speaker (keeping in mind the impedance considerations mentioned below). Impedance Considerations When connecting speakers in parallel be sure to check the rated load impedance of the power amplifier. Most power amplifiers are capable of safely driving speakers with minimum impedance of 8 ohms or 4 ohms. A pair of parallel-connected 8-ohm speakers have a total impedance of 4 ohms. Two 8-ohm speakers can safely be paralleled on one output. 4-ohm speakers, however, should not be parallel-connected with other speakers. These models can be connected in parallel, however, if you are using a power amplifier that can safely drive load impedances of 2 ohms or lower. Check your speaker impedance on page 18.
