Sure. Just take the output of the volume pot to multiple THAT Drivers.

Nope. Just take your input straight to the volume control (through a selector switch if you want multiple inputs).

Default My build

I used a SlimLine 1U 170mm case from ModuShop and sent the front and rear panels to Schaeffer for processing. Not cheap, but an excellent service and their Front Panel Designer application is easy to use.

I used Rivet Nuts to mount the PCBs

I included one of Tom's THAT Drivers to provide an output for a headphone amp and a board from CustomWorks to provide remote power on/off, volume control and trigger out to the power amp.

Here it is partnered with my Mod-286 dual mono power amp. I'm really pleased with how it sounds fed from a RaspTouch player with an IQAudio Pi-DAC Pro.

Nicely done, Sir. Which tool did you use to install the rivet nuts?

ukhopeful,

You got quite a lot going on there in a 1U chassis - well done! And also goes nicely with your Mod-286.

I used a Sealey AK3984 Short-Arm Threaded Nut Riveter.

FYI: Those who wish to build the DIFF PRE 8x2 should act soon. I have four board sets left. They're on sale while supplies last. You can find them here: Differential Preamp 8x2 | Neurochrome :: Audio
