Re: Transfer Console Monitor Controller

That sounds bad. I hope you get everything sorted out soon. We are waiting to get electrical service in the mountains. The pole is in. We are waiting for the electrician to install the meter and the excavator to dig the trench. I hope we get a good ground rod. I'm leaving the electrician alaone beca...

Re: A Monitor Controller

Thanks Paul! Would you prefer that it be a trim, fixed R or jumper/switch for the meter offset? I think fixed R with multiple possible positions. I'm thinking for digital mastering of loud mixes you would want attenuation. For using things like calibration records you would want gain. Both types sp...

Re: A Monitor Controller

That looks great. I could have used that instead of cobbling everything together from the M/S boards and some JLM boards. It’s perfect for a two turntable QC setup.

The only suggestion I’d make is to include meter offset capability.

Re: Texar Prism clone prototype Finished Version

I was trying to get 470uf 50v in a 10mm diameter. I usually use Nichicon HE but all I could find are Epcos at Digikey.

Re: Texar Prism clone prototype Finished Version

Are there any issues sourcing the MLCC caps? I have an open cart at Mouser right now for another project and haven't checked them. I’ve noticed lately that Mouser is picked over. I couldn’t get some non exotic aluminum electrolytic caps in the form factor I needed in any brand. Digikey has much bet...

Re: Mid Side M-S Matrix Uses No Precision Resistors

After thinking about it again I think the 8 pole 3 pos switch is the best answer. Signal Input goes to Wiper 1-4. Attenuator Input is from Wiper 5-8. In Position 1, Wiper 1-4 Signal input connects to Poles 1-4. Poles 1-4 are jumpered to Poles 5-8. Poles 5-8 feed Attenuator Input. In Position 2, Pole...

Re: Mid Side M-S Matrix Uses No Precision Resistors

I'm suggesting that you put the MS encoder, to monitor Mono or Difference, ahead of the Monitor attenuator. That way you have a low impedance source to drive the H-pad and you don't have to worry about the MS loading the pad. What advantage is there to it being post? It is ahead of the monitor atte...

Re: Mid Side M-S Matrix Uses No Precision Resistors

I'm trying to mimic the specified 1246 input with a 6dB pad. Shouldn't I be doing that for center channel headroom? If the 1246 could be made to have a 100K input impedance I'd be good.

Re: Mid Side M-S Matrix Uses No Precision Resistors

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...
