description: The hotel setup a registration page for us, so we're set for the same hotel, first weekend in May 2012. We'll get to do those fun Cinco de Mayo parties in Dallas at LSAF again this year, since it's that same weekend. At Uriah Dailey's request, I developed an IR remote control based on the AT2313 and AD5206. It can basically be the brains for a preamp, with five inputs and six channels set as three left and three right. The remote has power, input select, volume, balance and mute buttons. The processor reads both a remote control and frontpanel buttons for power, volume up, volume down, pan left, pan right and input select. Should have some of them at LSAF, probably one running in a Lighter Note in Uriah's room. You might notice the AD5206 is a linear device, but I have programmed the processor's firmware to send a logarithmic sequence to it so the volume control has an audio taper. This sequence is actually (much) more accurate than even the most expensive potentiometers, making this device attractive to audiophiles that might have otherwise chosen stepped attenuators.

Re: LSAF 2012

description: Yes, absolutely. The AD5206 can be used in place of a stereo potentiometer. They are available is several popular values, e.g. 10KΩ, 50KΩ and 100KΩ. So you can use this anywhere you might use a 50KΩ pot, for example. The switch inputs are just make/break connections to ground. So a pushbutton toggles power, another pushbutton advances input selection from 1 - 5 each time it is pushed. Then there are buttons for volume up/down and balance left/right. Or you can leave the front panel blank, and just use the remote as the only way to control the preamp. The outputs (besides the volume, which is a variable potentiometer) are all digital outputs, intended to drive a (mechanical or solid state) relay. Each control line sources a maximum of 40mA, but I'd suggest limiting that to 20mA. If more current is needed, just drive a small signal transistor or something, like a 2N2222. Drive the base, tie the emitter to ground and the collector to one side of a relay coil. Hook the other side of the relay coil to Vcc. Easy peasy. The available output pins are power, select1, select2, select3, select4 and select5. Those select lines select the channel, which would be hooked to a switching device (relay) through the AD5206 potentiometer. Lots of flexibility there to work with.

Re: LSAF 2012

description: It's not expensive. The remote control itself is a generic universal - just get any one you like. I prefer those that have the up/down and left/right buttons prominent, as opposed to the remotes that have vertically arrayed channel up/down and volume up/down. But any of them will work. Then there's the control board. I'd say by the time the boards are etched and deals are struck, it's probably going to be less than a hundred bucks for the completed control board. Having said that, it's all still preliminary. The design is done, prototype is working. I can burn chips right now, and can probably have boards etched in less than a month. But I do need to figure out pricing and delivery model. I don't know if I'll make them available directly or just through OEMs. I have plenty of friends in the business that manufacture amps, preamps and kits, so it might make sense to make it available to them, and let them brand them and resell them. I need to work through all that first. Still, by LSAF, the business side should all be worked out.

description: Hi Wayne, If I can work it I plan on bringing a pair of Martin Logan Vistas this year. They really shine with Oddwatts. By May we should have the final versions of the KT120 mono blocks as well as the all valve phono preamp. If not prototypes for sure. If you care to bring along an spare sub woofer, we would be happy to find a way to drive it. I expect to do both vinyl and CD especially since I will have my re-tipped (ruby cantilever ) Dynavector back from Soundsmith by then. Perhaps some other cool things . may find there way to LSAF by May, lots are in the oven. Like I mentioned in the the off line emails... keep me in mind on the remotes. They should be applicable to some of the kits.

Also to get the juices flowing we (Oddwatt) are planning on giving away a number of things this year. Initial plans include an "Alpha" amp, "T" Shirts and what ever else we think might be cool. It is a definite that the Series I KT120s will be there, the Martin Logan ESLs about 90% for sure, new phono preamp with my modded Dual 701 TT and the ruby re-tipped by Sound Smith Dynavector 10X5. Lots of other stuff as well including the new version of the Poddwatt and "Retro" Oddblocks (I really love mine - all octal tubes).

I haven't built any single driver full range speakers in some time, and I've ordered a pair of Mark Audio Alpair 10.2 full range drivers, which I plan to use in Jim Griffin's MLTL design, built out of Baltic birch plywood. After a first listen I'll have to decide whether to add a baffles step compensation network. I prefer most single drivers with this, but it's upsetting to see the purists running from the room with their hands covering their ears repeating over and over again "must remain pure, must remain pure..." http://homepage.mac.com/tlinespeakers/FAL/downloads/Griffin-A10-MLTL-030611.pdf

Bob Brines has developed a similar MLTL enclosure for the Alpair 10 driver, and he suggests about 20-30w/ch for adequate headroom. http://brinesacoustics.com/Pages/M10-A10/Main.html

Your exhibits a couple of years ago were some of the best sounding I've heard at any show including the RMAF. Your participation will be helpful to me in convincing my Houston Audio Society friends it's worth the drive to Dallas. I'm glad to see you plan to "get behind this show". The LSAF isn't anything like the big commercial shows, and most of us want it to retain it's character, but I still believe we need to increase the number visitors (and exhibitors) to achieve a critical mass. Your return is a great help in this direction. The LSAF isn't a show that can buy ad space in Stereophile and TAS, and it's success depends on the exhibitors promoting it. I'm hoping all the other folks who plan to exhibit this year will start promoting the show as you plan to do, with discussions and pictures of the products they plan to bring posted on the various audio forums. With only two months to go we all need to start creating some excitement about this fun event.

It's our show - not put together by a promoter - so we get out of it what we put into it. This is not a "for profit" show like all the others, so it depends on our sweat equity, our promotional efforts, our messageboard discussions and other ways of getting the word out. I really like it, because it is easy to participate, all-inclusive, and it feels more honest to me that way. And to Danny, sorry, I don't know how I missed your post or I would have extended a hand to you and Gary sooner. Welcome back!

OddWatt Audio At The 2012 LSAF

Saturday I hit the "order" button for a Poddwatt kit, which I plan to use with my Oppo BDP-95 player and Jim Griffin's Mark Audio Alpair 10.2 equipped mass loaded single driver speakers at the Lone Star Audio Fest. I borrowed this little amp for a couple of hours at last year's LSAF, and I liked it so much I knew that I would eventually be getting one. Bruce, have you decided what you will bring? I would expect to see the ForeWatt, the OddBlocks, and the KT-120 OBHO's. Any other Odd products we should look forward to hearing? It's always Odd to hear from you.

description: hi Fred, I missed your post a few days ago. I remember that you heard the Poddwatt last year. They are really neat. For their size they are about as good as it gets. For what was originally designed as a sort of utility amp, they really came out well. A few changes from the originals since then, but the overall character is unchanged. They share what I have come to call the "Oddwatt" sound. It seems that all the amps from the Poddwatt to the KT120 sound quite similar. Clean, fast and quiet with very wide range response (sorry not intended to be a commercial for them) Anyhow, We will have the full range from the Alpha which is really a sort of starter amp and not really in the same league as its bigger brothers to a set of KT120 mono blocks. These are the pre-production ones and except for a few cosmetics and a slightly different chassis will be the actual production kits. For source material my modded Dual 701 direct drive TT, three cartridges (Soundsmith ruby cantilevered Dynavector 10X5, Benz Micro Gold low output MC, and a Grado Reference Platinum I), an Oppo 83SE, the new phono preamp (lovely sound, super quiet), a remote control Forewatt, probably the prototype fully integrated preamp with phono section and remote, bunches of amps, and the Martin Logan Prefaces we used last year. I would love to bring the Martin Logan Vistas, but they just won't fit in the vehicle if I pack them right. I considered a trailer, but I really don't want to haul one a thousand miles each way.

Since then I used the original (doesn't look like that) in my former office for nearly 3 years and it is still running perfect. They are a great match for speakers with efficiencies over about 90 db/w. I can use one on my Martin Logan Vistas and unless you really like loud music it is just fine. I used them on Klipsch KG4s in my office and everyone loved the sound. I look forward to seeing you at LSAF. I'll be getting in Thursday PM.

description: Keith, You should drag your measuring system around room to room. Take a 1 meter gated response showing speaker response only. Then move back to the listening position and show the response of the left speaker and right speaker (independently) with the room reflections. I think it would be an interesting learning experience for many and might help sell your measuring system.

description: I think that's a wonderful idea in principle, but maybe a little bit annoying for the attendees. The measurement signal is not particularly pleasant to hear. I think most people will probably want to hear music instead of MLS bursts. Still, I think it's a great idea, especially maybe after hours for those that are interested. Seems like Friday afternoons are perfect for this too, while everyone is getting dialed in. But Saturday afternoon would be kind of rough.

description: I can easily make rounds with my laptop and a tester in tow. I can recall my own LSAF experience with my line source subs producing a rather big hotel room bump and dip. Not having any room treatment, the only option was to move the subs around to clear it up. Anyhow, all that is needed is an RCA line input into the system. FWIW, the software supports MLS, noise, chirp and a sawtooth impulse. IMO, the impulse is a lot less annoying to listen to. And, in the new version signals can now be summed together and spectrum shaped. Look for "New Signal Types and Combining Signals" in the V6 release notes. http://www.woofertester.com/v6_notes_release.pdf

description: Vapor Audio will be there again this year! It's looking to be a much improved show over last year, and I'm very much looking forward to it! I might end up having two rooms. I'm looking at the Frisco conference room, which is unfortunately at the far end of the hotel past the breakfast area and pool. But I think I can setup enough signage that people will find me. And then if I do get a conference room, I'll try and bring some help so that I can setup and run another room in my sleeping room. Companies I would represent: Vapor Audio - likely a pair of Cirrus and Breeze, and also a new design called Cirrus White BMC Electronics - their stereo amp called S1 and DAC called DAC1 Antipodes cables Arte Forma - their KT88 based tube integrated called Else MkII

description: Hi Everyone, It looks like this will be a great fest. Last year was our first and we enjoyed it a lot. This year seems to be even bigger with lots of good things to see and hear. We will have the full line of products from the 1 watt / channel Alpha to a pair of the KT120 mono blocks. We will have several of the line stage preamps and a pair of the phono preamps. Everything is as before all valves in the active circuitry. Main source will be vinyl with CD and Blue Ray for backup. I expect to roll in Thursday PM so look me up if you get a chance. The gear will not be set up until Friday though. Bruce Heran Oddwatt Audio

description: I thought that I would post this update here as well. There was some talk about me hosting a little after hours small two way speaker shoot out but I it hasn't materialized yet. I contacted the local YG Acoustics dealer but he did not have any more Carmels on hand. Otherwise he was interested. YG Acoustics has been pushing some head to head comparisons in the past. If any of you guys come up with some top level monitors or small floor standing speakers and want to do something like that then let me know. I do have a larger sized room that will be well treated. I'll have some top level gear there in my room as well. So it makes for a nice location. It looks like I'll once again be showing with a pair of Super-V's. So if you guys have still not had a chance to hear a pair, now is your chance.

description: Seijinaudio wrote on Thu, 26 April 2012 19:30 I would be interested on participating depending on what front end the setup will be for the shootout. The source is Mach 2 Audio modified Mac Mini with external 12 volt power supply. The hard drive is also external. The DAC is a new db Audio Labs prototype. The pre-amp is a battery powered tube pre from Dodd Audio. The amps are battery powered tube amps (mono-blocks) also from Dodd Audio. It is basically the new and revised version of the system that we used at RMAF that was voted once again the best sound at the show by the Absolute Sound. It is a top level system from top to bottom, cables and all. And it is completely off the grid. The room will also be well treated using curtain's, foam traps, and PI Audio diffusion panels.

But I only have one decent rack, and limited space in my vehicle. If any of you local dealers could loan somthing, I'd be happy to let you hand out literature or put up signage in my room.

Wayne, I have 3 sets of interconns from Black Cat, and pair of RT series Polk bookies for raffle, did we ever decided how to do this, are we just going live in the lobby, drop your name in the hat, and we draw in 10 minutes? I see the 'judging' etc has become more formal on other boards, which is fine, I thought we were doing a simple ballot for attendees to write down their fav room, to be announced at Sunday breakfast with the exhibitors? Cheers, Russ And of course the box of Polk T's, which I'll hand out room to room like last year if that's ok, seemed to work well. I especially like it when I handed the Stereo Clarity guys one, and they started polishing their speakers with it! Colleen Cardas and Marc Phillips (my friends and Unison Research connection) will be in attendence Fri night and Sat day. If you have ever wanted to meet Colleen - I know just about all of us have used her wire and binding posts - and Marc is a hard core vinyl blogger, cigar junkie, and all around audio nut. A couple people worth sharing some words with.

Excellent, Russ. I think the attendees are in for a real treat this year. Lots of goodies. I brough a pair of two Pi tower kits and three ART T-Shirts to raffle too. Last I heard about the raffle is what you saw in the emails yesterday. Steven is going to hand out some cards, we should encourage guests to fill them out and return them to the room host so they can be entered in the drawing. russman wrote on Thu, 03 May 2012 19:36 I see the 'judging' etc has become more formal on other boards, which is fine, I thought we were doing a simple ballot for attendees to write down their fav room, to be announced at Sunday breakfast with the exhibitors? Well, I don't know about all that. I just know Raven Audio donated some trophies and they and Stereo Clarity sort of championed a "Best of Show" event. Don't know how it's gonna be judged. I'm just here playing some tunes, checking out Bruce's amps. I agreed to demo with his gear this year. So I'm just messing around having some fun.

description: I stayed up way too late getting setup. So I'm sleeping in tomorrow. But here's what I brought this year: You'll notice the four π mains flanked by three π subs. Not surprising there. But what's new is I'm not running my usual amplification. This year, I'm using Oddwatt amps. That's what those two monoblocks are on the bottom shelf. I also have the remote control RDAC "passive preamp" mentioned at the beginning of this thread. It's the box up top with the "005" on the display. This is another one of Bruce's Oddwatt creations. He built a prototype passive preamp based on my remote processor chip. The numeric display is his way of providing visual feedback on the volume setting. You can do it with a bar graph or any number of ways, or not provide a visual indicator at all. But any way you package it, I like it because it's just one single (wiperless) part between the source and the amp. No mechanical contact via potentiometer getting in the way.

description: Hi All, I'm driving up from Austin and should be there tomorrow afternoon. I have a passive-pre I would like to compare with anyone elses pre-amp (passive or otherwise) if someone is interested in taking the time. I would value any expert opinions I might be able to get. You may know it as the Bent Audio TAP-X. They're not sold anymore but I bought the parts from John Chapman and put one together. I really like the sound of it but have never been able to compare it to anything other than the pre's I have owned. If you're not familiar, it offers remote controlled souce switching, volume and balance control. Volume control is via transformers from Dave Slagle. If no one's interested that's OK too. The fest looks like a good time. Cheers Phil
