Dolby Noise Reduction Processors and Parts

Synhouse had a huge inventory of Dolby gear and most of it sold pretty quickly. Synhouse STILL has more Dolby gear than anyone.

The rest of it is still for sale as listed below, and a few very nice Dolby machines that were used here or reserved for company use and are no longer needed will be sold as well.

I will be selling an MH series M16 which is the Dolby factory correct 24-track setup which is a fully loaded 32 channel frame (that is proper, says 1-32, not 1-16 twice, and 25-32 blocked out with the factory panel made to do just that) that is serial number 3 (00003) from Motown (also 00051) with 24 Cat. 22 and 24 Cat. 44/44H, absolutely museum quality, possibly an ultra rare Dolby Cat. 35 NRM test set to test Dolby Cat. 22s (in brand new, MINT condition), many, many Cat. 22, Cat. 44 and 44H interface modules that were all tested good in 2006 and sealed in boxes in the warehouse since then, some Cat. 231 bypass modules, all tested good, plus a box of Dolby stuff that was separated from the rest because it tested bad.

More items will be listed as soon as I can get to it.

Update 8/18/2023:

Most of this has been sealed in some of my 300+ flight cases in dry storage without a touch or even a glance since 2006 or so, so I will go ahead and list some of it below. I have listed items that I believe to be in stock (if my documentation is correctly updated), though there is a chance that some of it might have been sold and not recorded. ALL of the Dolby card/module stock was moved 9/2022 and at the time of this update hasn't been sorted and restocked in the new place and some of it is selling, so most of it is much easier to access than it had been before.

Inventory of Dolby Laboratories products:

$49     Cat. 22 Single A-type noise reduction
(more than anyone, tested good) (+3 with the three Cat. 43s) (+ many more that tested bad, you can get those at a really good buy, 9/1/2023 there are five Cat. 22 that failed tests that are available for $5/each, after those sell there may be more bad ones as more stock gets tested out and sold)

Cat. 35 NRM tester

Cat. 43 Post production sound processor for 360 series processors (an ultra classic, still the best, a 43B card with XLR cable and control panel with 43A fader board, also have extra parts)

Cat. 44 Interface module
(for M series multitrack frames)

Cat. 44H Interface module
(for M series multitrack frames)
(more than anyone)

Dolby Tone Monitor Speaker Volume Control A2PM836 (might also be called a Cat. 45 or Ser. No. 45, goes in the lower right slot of M and MH series multitrack frames) (5)

Cat. 47 Service Module (Bypass module MH studio NR unit)
(only 1 left, probably won't sell, still using M16 frames here)

Cat. 231 Bypass board for XP / SP series
(a few left)

Cat. 280 SR Spectral recording module (works in 361 frame and ???)
(supposed to have two in my 361 frames, but I haven't seen them in a while)

(the Cat. 331 Dolby A-type noise reduction module for XP and SP series are all sold out)

361 1RU frame
(at least several, but some are still in use here, and people tend to want to pay a price that doesn't even cover the work that goes into them, and I don't care how much garbage untested frames with broken switches go for on eBay, I don't buy or sell trash like that)

(the Cat. 431 Dolby SR-type noise reduction module for XP and SP series are all sold out)

Dolby 361 frames access plate emblems
(new) $10 for 2 (2 pieces of the tiny thick metal replacement emblems ONLY, not the access plates, and not the Dolby 361 frames themselves, this is just the shiny metal part that peels and sticks onto your own access plates)

(I think the DBX K9-22 Single channel DBX Type I module for Dolby frames were sold out, but then I found that I still had two more, super rare and groovy)

Synhouse had a total of 477 Dolby products in stock in 2006, the above is a fairly complete listing of what is still in stock and not needed for internal company use.

I have a huge box of have box of broken Cat. 22s,  44H,  and one 280.

Please inquire if you have requirements for any of the above.
