Hi my name is diederick kavelaars.
I have been interested in making amps for a long time and have desided to build the leach poweramp (double barreled) at 300 w. Now since I do not own a tapedeck or a phonograph I will only be using this amp with my computer. Having said this I think this would provide me with enough power to blow the windows out of my room using the speakers I have, bang & olafsen (4-8 ohm,87db,20-120W) the only thing I am still looking for is a good passive preamp. I do not like the zen family because in conjunction with the leach low tim amp and thus the double barreled one as well create a slight hum. This is something I want to avoid. therefore I was wondering how I would go about designing the following.
A passive preamp, incorporating hte following:
-Volume control
-source selector 4x (aux)
-outports 4
-loudness
-bass
-treble
Bass treble in a 5 or 7 band equaliser (in case of 5 band 100hz 300hz 1khz 3khz 10khz)in case of 7 band I don't know.
The only other requierments are that it should not create a buz hum thumb click at trun on/off, that it should be as fast as a ferrari and it should be compliant with the double barreled leach amp.
about which I have some questions as well. following here.
i would like to hook up some 8 speakers 2 subwoofers and 6 4way's. i understand this is somewhat ambisious but can i do this or would i be advisable to build two amps and biamp or build two and run subs and 4way's separate.
I have some electronics qualifications but when it comes to designing this new preamp i am feeling in the dark and about the speeker setup, one or two amps i am curious about your oppinion.
I realise this is a lot of questions all at once but i am dying for information as i have a lot of free time on my hands now. love to hear from you and what you think of my project.
