Dear All,

I have one Karaoke system with 2 wireless mics and 'aux in' to connect laptop audio output.

It has 15" 80W speaker and is a 220 V system with a 12V battery for backup inside.

However to record my songs or youtube video it does not have a 'line out' port to connect to my Android or iPhone.

Can anyone suggest the right method to design and insert the 'Line Out' circuit on this box? so that I can record the audio/video as well as the box will give out sound as usual.

Can we open the box and connect such circuit (filter) to the speaker output directly and take a 'line out' or is there any other way without blowing either i/p or o/p?

Hi Bill, I am referring to your video on -

Build a Line Level to Microphone Adapter - Record from your Phone to Computer or Camera'

Can this circuit be inserted at speaker out put (or elsewhere?) if yes whats the voltage of capacitor?

appreciate any help here.  (I can paste the backend picture of ports if allowed as no more attachments allowed today)

Regards.
