Hi spiri,

once again thank you a lot for your most educating contribution in the German forum.

Please count me in for a balanced version.

Cheers,
Josip

Hello,

you website seems down, I can't connect.
Also so you have a solution for HT bypass ? If I build a preamp I'd need to make an input directly connected to the output (ie with the volume control bypassed).

Cheers,
François

Thank you, we work on it.

With our Muses Controller, each input can be assigned with a fixed attenuation. This is to connect a HT system. The volume control with the rotary encoder and also with the remote control can not change this value.

Thank you for your answer !

I have other questions then.
Can one volume control work in balanced mode, or do I have to get 2 ? In this case, is it possible to use an unbalanced signal as input and get a balanced signal as output (My HT preamp is unbalanced) ?

Edit : Got my first answer for your pdf : for balanced mode I need 2 control volumes.

Unfortunately, the initial interest in the mini muses boards has faded quickly.
Until now, there are only 16 MINIMUSES and 10 MINICPU on the list and that is just too little for a new production. So we will close this GR.
Thank you all for the inspiring participate in the product definition.

The AKOUO Volume and Select board is still available and in the meantime we also have the analogue stages for a complete pre-amplifier.
