remote controlled speaker volume

[Nigel Goodwin]

You do not need amps for every speaker. You CAN use a speaker attenuator. It is also known as a "L" pad. Its a high power potentiometer.
You can switch high power resistors in series with your speakers with a remote to attenuate your speaker volume.
google "speaker attenuator" to get started.

You obviously didn't bother reading all the thread

He specifically wanted NOT to lose quality.

Nigel i dont want the quality to be reduced but my primary amp is like 1000Watt. So can i use the method 4pyros mentioned?

The thing is, the input signal for the remote controller kit is already pretty amplified. Will the PIC microcontroller be able to read it?

I suggest you google "100V line", which is what is used for multiple PA speakers in hotels etc.

It doesn't give what you asked for, but does allow simple switched volume levels, or a crude 'volume control' using a high power pot.

It also completely destroys the damping effect from the amp, reducing quality.

Of course, you just need to reverse engineer the protocol used and write the software to do so.

Nigel; How dose using an L pad reduce quality? Its done all the time for remote speakers. It justs waists some power.

I believe thats a 70 volt speaker system.

It also completely destroys the damping effect from the amp, reducing quality.

I believe the 70 volts amps are designed with a transformer output having little effect on the damping.

How many watts are your speakers rated for?

Hear are some remote control speaker volume controls;

Already explained in the post directly above your question.

Not in my country, but as you don't have your's filled in I've no idea what your's might use.

I believe the 70 volts amps are designed with a transformer output having little effect on the damping.

Why would you believe a transformer would have little effect on the damping? - 100V line isn't intended to be high quality, basically mostly background music and voice announcements (and often using just PA horns, so no bass anyway).

Here is a digital unit;

Seems like most of the off the shelf stuff just passes the IR back to the sorce unit.
If this is not what you want then maybe you can mod the digital units with key fob remotes ( made for automotive use) on different channels to control the up and down buttons on the volume controllers. Thats just the DIY in me. Look around you maybe able to find something that you like. Andy

The transformers are supost to keep the same load on the amp.
The L pads are also supost to keep the same load on the amp.
Both of these methods will reduce the effect of the volume control on the dampening factor.

Yes I would never use a high voltage speaker system for High Fidelity.

I have 7 speakers each rated for 40Watts

You appear to be unaware that the transformer will completely destroy the dampening effect of the amplifier - as will long speaker wires for that matter (but no where near as much).

 

[4pyros]

You appear to be unaware

Nigel; I am not unaware. I just dont think that the dampening factor is of major concern in this case. Everything is a trade off and in this case using L pads may be more acceptable than building 7 amps. The effect that off the shelf volume controllers with correction will have on the damping of 40 watt speakers will be so small no one will care. For all we know the OP has cheap speakers mounted in a attic space with hundreds of feet of 16 gage wire. I don't think we have enough information about the situation to make a disishoin for the OP.
L pads are just one of the options available to the OP thats used all the time. Andy
