Yamaha KMS-301

This speaker system incorporates a speaker protector. However, if first you will drive speakers with a high-power amplifier, first decrease the volume to minimum, then turn the power on, and increase the volume slowly. If high power output above a certain level is applied to the speakers suddenly, the protector will not function and so the speakers will be damaged.

The required length of a screw differs depending on the mounting bracket to be used. Select a screw which is suitable for use with the mounting bracket and can be fully inserted into the hole on the speaker.

Connect the left speaker to the left (marked L) terminals of your amplifier, and the right speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, -). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass.

Do not fasten the speakers to walls with nails, adhesives, or other unsound hardware. Long-term use and vibrations may cause them to pull free.

To avoid accidents resulting from tripping over loose speaker cables. fix these to the wall along with the speakers.

Built-in Speaker protector

This speaker system incorporates a speaker protector which protects the speakers from excessive input. Once an excessive input is applied to the speakers, the protector functions and cuts sound output from the speakers. If it occurs, decrease the volume on the amplifier. After several seconds, the protector stops automatically and sound output revives.
