Re: Active Summing mixer using THAT Ic's and some...

I do understand this but I don't understand the part of "adding a few resistors"... Here a simplified picture of the connection between the master pcb and the output/buffer pcb.. http://i241.photobucket.com/albums/ff3/radiance2004/SimpleConnection.jpg Is it as simple as adding a resistor ...

Re: Any opinions on this console?

That link to a bend primer supports my point that they call it art because they don't have a handle on the variables. Their "K" factor is just a classic fudge factor. Another variant they didn't mention is bending finished metal. We used to use some special dies that I think were teflon co...

Re: Any opinions on this console?

I have known Steve for many years. I think I wrote a letter pointing out a mistake in one of those Studio Sound console articles. Nothing major but IIRC he generated a bunch of hypothetical topologies and one of them did not do what the article said it would. I had written an article on console desi...

Re: Any opinions on this console?

'BUS' is kind of a hobby of mine. I recall a spirited discussion with the editor of Studio Sound back when there was a Studio Sound about buss being the "brit" spelling, which he vehemently denied (he was an editor after all). Spelling bus wrong seems to an affectation of some console mark...

Re: Any opinions on this console?

I thought there were some guys on prodigy talking about personal purchases of hand brakes (to bend sheet metal), shears, and maybe even some modest NC milling capacity. If somebody made such a personal investment they would surely be interested in getting some more use out of it. I know one guy who ...

Re: Any opinions on this console?

Since I used to publish a lot of kit articles in Popular Electronics, I have a funny story.. I was enlisted to make a CX record NR kit... I was promised a cover article and free license from CBS, so I said sure. In the course of designing my kit, I found a mistake in CBS's documentation. They publis...

Re: Any opinions on this console?

I have never had much luck or stomach for pursuing such esoteric markets. I second the post suggesting if you want to look like an old API, buy one used.. The old API stuff is probably respectable enough if recapped or whatever. Not much need to upgrade old discrete opamps. JR PS: Yes I saw the mete...

Re: Modern stereo specs - quoted 10% THD

It's probably a little specsmanship to hit a round or marketing significant output power number.. Guitar amps are typically specified at 3% or more for this same reason. Professional power amps are sometimes specified at 1% instead of typical distortion figures, easily an order of mangintude lower s...

Re: Any opinions on this console?

It's interesting looking, in retro way. Patching in different gear looks a little scrambled up. I didn't see any basic EQ, or mic pre's so I assume you have to patch in external after market units. A front patch bay would facillitate that. I don't get the small VU meters, they look too small to be p...

It wasn't really their decision to leave nasdaq.
