[Anthony]

HI everybody,

I whish to use a passive pre after my sound card (+4dbu) with my new amp9 and i found this on ebay

http://cgi.ebay.fr/4-way-Motorized-R...742.m153.l1262

but it's a 100k pot.

Do you this i could use it ?


Thanks

100k is a little bit high.
A 40 or 50k pot will do better.

The input impedance is to high with a 100k pot. This can generate noise.

This is exaclty the point that scares my.

Thanks a lot i will find another solution

Regards

I use the Taiwan Alpha 10k dual log pots a lot, they are very good. There is even a thread on diyaudio. In Australia we call them "Jaycar Pots". Jaycar is a popular electronics shop that stocks them.
