L-Pad
I have a Siren Amplifier Unit it says use 100W speaker (105 Watts RMS
Max) im using a 20W Siren Speaker i dont know what ohms it is, the speaker it says to use is 11 ohms will it damagae the siren amplifier unit if its not 11 ohms, it sounds ok but its a bit loud for its usage so i got a 100W L-Pad to control the volume, it worked but then started smoking the speaker wires from the siren amplifier unit output 33VAC |

Were you thinking that there is a question in there? |

I do this as well. |

What are you talking about? Do you have a device that produces a siren sound
into a speaker? If that is the case, then just get a high power resister and put it in series with the speaker. This will solve two issues. First, it will reduce the volume of the speaker and second, it will add to the impedance of the speaker so that the whole system won't draw so much current. You can figure out what value of resister to use by thinking of it as a simple ratio. If the speaker is 8 ohms, then an 8 ohm resister will absorb about as much of the voltage as the speaker; effectively cutting the power to one quarter. Why a quarter and not a half? Because, an 8 ohm resister will drop as much voltage as the speaker, but the whole circuit will have twice the impedance, so only half of the current will flow through both the resister and the speaker together. So, half the voltage times half the current is one quarter of the power delivered to the speaker. Watts is volts times amps. An L-pad is a specially designed device that has two variable power resisters in it. One resister goes in series with the speaker, much like what is described above and the other resister is used in parallel with the speaker and the first resister. This has the effect of dropping out the added resistance so that the resulting impedance remains about 8 ohms. These things are mainly designed for applications where a speaker must maintain a constant impendence, like a mid or a tweeter in a system that has a passive crossover. I don't think you need an L-Pad. James. ) "-L-" wrote in message oups.com...

Turn it down! |

I don't think you need an L-Pad.
LOL, I don't think he *has* an L-Pad anymore! |

well... depending on where the smoke came from... I'm not sure.
