A Question about TVC Pre Amp
« on: 22 Aug 2008, 05:53 am »
Hi,
 I've been looking at the TAP six input pre with great interest. Aside from my curiosity about using a TVC in my system,  the HT passthrough and 2 XLR outputs are perfect for me. I was wondering if it would be possible for you to modify a unit so that one of the XLR outputs could be trimmed? In order for my system to work optimally I have to shave about 3.5 db from my bass amps. I could always use a pair of  of Rick Schultz' output attenuators but I'd guess that if you could do something internally it would probably be better . Thanks.

Hello!

First of all that pic in your signature is freek'n me out.....

The system is not setup to trim like that - although I will keep it in mind. The sub output on the current unit was done thinking of a sub connection - and most all subs or sub amps have level controls on them. I bi-amp myself from time to time and I know just what you need to do since I run into that same issue. Thanks for the suggestion.

Ricks attenuators would be great. Maybe a -3db pro audio XLR type attenuator (likely out there) would be a good clean way to do it if you know the atten level needed up front.

The current (new) 6 input TAP-X pre-amp is all RCA connections. It is rather easy to do a true ballanced unit and I might do one but - man - it drives the cost up. The Autoformer modules are the most expensive parts inside by far and to do bal right you double those up....... It'll be pushing $3K for a bal TAP-X I think. I have done a couple single input / dual output  bal units for folks and they work really nicely - just trying to decide if there will be enough market at $3K for a multi input bal one to go ahead and do the required design work and get a production batch of the parts needed, etc....

Maybe I should start a list and if I get to 5 guys who want'em then I'll spring that project loose. I am pounding away (literally) right now at the web update and will finally have the new stuff all online next week. I want to get that all buttoned up before I dive into any new design work!

Thansk!

Hello!

Yes it is but I have yet to figure out what he's saying. He's awfully excited about whatever it is so maybe it's better that way.......

Thansk!

John,
 Tricky Dicky is merely reminding us that he's not (was not?) a crook.  He was pretty scary at the time but in retrospect it all seems kind of quaint. I own a pretty interesting collection of political memorabilia and I find him to be the funniest president of my time. I recently got a chance to watch the entire Checkers Speech for the first time and it was just bizarrely compelling. What an operator. i guess I'll eventually replace the picture, possibly with a picture of J.Edgar Hoover in a sun dress.

About the TVC. I'm definitely interested in a fully balanced model. I'm thinking if of going with the Rick Schultz ultimate attenuator but I'm also considering a goldpoint attenuator.  I Tried to find a balanced 3 db attenuator but all I could find was 10, 20 and 30db models. If you decide to build a fully balanced TVC with a home theater pass through let me know.
