With a topic derived from the members music section, I am coming here in an attempt to scrape off some of the dirt covering the area of my brain that's supposed to be dedicated to technical understanding. :?
I own a Fender Prosonic described here http://en.wikipedia.org/wiki/Fender_Prosonic, and face the challenge to capture the broken signal from it (for recording purposes), at levels suitable for neighbors and local authorities. In a feedback exchange, jcwu (and I thank him again for that) suggested the use of an attenuator. He is using a Weber himself on a Peavey amp.
My specific question relates to the attenuator power / amp power ratio. As you saw in the prosonic description, it's unique feature is the rear-mounted RECTIFIER/BIAS switch lets the user select from the following three options:
1. Solid-state rectification with fixed bias (marked "S.S. AB2"). Listed at 60 Watts R.M.S.
2. Tube rectification with fixed bias (marked "AB2"). Listed at 50 Watts R.M.S.
3. Tube rectification with cathode bias (marked "A"). Listed at 30 Watts R.M.S.
Based on this info, and the fact that I would like being able to use the attenuator for more than an hour before seeing flames shooting from the tubes, what attenuator power and type would you suggest I use and on which rectifier position?
Since there is a big difference between the 30 and 60 watts ratings from the "SS AB2" position to the "A", and since it doesn't take much to get me confused, I am confused..... :roll:
Thanks!
Oh, and in case you need it, here's jcwu's link to the weber attenuators, pointing out the importance to select the right type and power attenuator for the given amp....
