I would like to use the Encode half of the M/S board(s) in my monitor controller for Mono and Difference. The Monitor Controller uses a balanced H pad with a 10K input impedance when both are fed in parallel. I would like the input to the M/S board to have an input impedance of 100K so the input sti...

I still have a pile of the V1 PCB's that I get good use out of. This is a nice addition to the line.

Sounds like a good plan.

Will it be possible to bring any of the 'under the hood' parameters like attack, release and ratio, out to the front panel? To use it in a production as opposed to broadcast environment I think that would be necessary. Really cool project though. Following closely.

I think Wayne mentioned it in another post but I've been finding Digikey has stock of many items, like Meanwell PSU's, that Mouser is out of. Mouser is my first call but I check Digikey if Mouser is out of stock.

Studer made a layback machine? Wow, that brings back memories of the MCI JH-110 1" layback I used to have to maintain at DSL. The 1” Preview deck was pieced together from the 1” layback machine and a 1/4” parts machine. I got the layback machine in Toronto. It was missing the headstack. That a...

I have the low impedance heads on my 1/2" machine. I have high impedance heads on the 1/4". I can scan that one too. It has a 1:10 step up transformer that is terminated on the secondary with a 180K resistor in parallel with a 33p capacitor. After the front end it's exactly the same as the...

i think the schematic you're looking for is in the A80 VU Mk II … IV file. That's correct. I have three A80VU Pre. They are not strictly any vintage. My 1/4" machine has the MkI frames with the Weston meters but the electronics are MKII. I'm not sure about all the differences between models me...

For both 15 and 30 IPS? Anything will do. Just one setting will work. This would just be for 'proof of concept'. As long as I can hook it up and play a tape it will give me enough information to know whether I want to pursue this further. I know there won't be adjustable Hi and Lo frequency adjustm...

Cool. What would it take to convert the RIAA EQ to an NAB or AES EQ?
