Connect amplifier to bluetooth speakers

[Inez]

Hi,
I would like some help with my set-up. I'm not very technical and don't have an impressive set-up like most of you,
but would like to know more about the following

I have an amplifier in my living room connect to two speakers.
But I would like to also be able to listen to music in my kitchen and thought about installing a pair of bluetooth speakers.

I know you can get an bluetooth transmitter and plug it into your PHONES output.
But is there perhaps also a way you can use the speaker output from the back of my amplifier?
So I can also use the front buttons 'speakers A' and speakers B'

Thanks in advance!

You can do that, but you'll need an attenuator between the 'speaker outputs and the Bluetooth transmitter, as the voltage out of your amplifier will be excessive for the Bluetooth transmitter. Easiest way is to wire a 10k log pot across the 'speaker outputs, and adjust the pot such that you get a usable range on the amp's volume control with enough loudness on the Bluetooth 'speakers.

If you're not up to soldering, you could just buy a simple passive volume control and wire that in.

Actually, a new idea. Is it possible to use the tape - REC (OUT), to hook it up to a bluetooth transmitter?

Yes and no! (helpful aren't I?) You can, but you will have to adjust the volume of the bluetooth 'speakers on those, as the tape output comes before the amp's volume control. If that's not a problem, or indeed is preferable, then the tape outputs is actually the right place to connect the Bluetooth transmitter.

Very helpful!!!
Many many thanks for taking the patience and effort to help me!

I had faced this problem before and your idea helped me also. Thanks

You can definitely use the speaker output from your amp for Bluetooth speakers. Just get a Bluetooth transmitter that plugs into the speaker output, and you can switch between your wired and Bluetooth speakers using the 'speakers A' and 'speakers B' buttons. It's a simple setup and should work great!

Whilst you're right that one 'can' use the 'speaker outputs for a Bluetooth transmitter, you will almost certainly overload the inputs to the transmitter unless there is an attenuator on the amplifier's output, or you keep the volume control very low on the amplifier. The problem with doing that, is that there's then little control over volume, channel balance (if relevant) is likely to be poor, and the amplifier's noise is unattenuated, so may be audible.
