Re: DPOTs for audio control
So what are you going to do JR?

Re: DPOTs for audio control
Yes. VCA, SPI interface for control, stored wiper (gain) setting, slewing between steps with an external C to eliminate zipping. Add an analog Ec for realtime control. The VCA always wakes up with the last gain setting and moves between steps with a smooth linear dB slope.

Re: DPOTs for audio control
Thanks for posting this John. I know that in your application that the ADI LOGDACs might be too expensive. They also zip but IIRC are monotonic in their gain steps. Have you ever tried them and is ADI still in production of these? I remember them being used in the Studer 820 and MCI/Sony APR-24.

Re: automatic timing in compressor confusion
In your second try using the NLC you mention a 10K resistor. Where was that in the circuit?
Thank you for joining us!

Re: THAT1646 Current Booster and Transformer Driver
I think it fits here fine. One is for phones, one for transformers. Need to start one for driving cable.Oops, wrong thread!
It's very adaptable circuit...

Re: THAT1646 Current Booster and Transformer Driver
Roger - Thanks. I may need to clarify something for our readers. The circuit Roger is refering to is not actually posted in this thread but is the headphone amplifier with external driver transistors. For the sake of clarity it is here: https://www.ka-electronics.com/Headphone_Amp/Headphone_Amp_1646...

Re: dBx 3BX Three Band Dynamic Range Expander
That's the one I remember. Very clever.
