I'm looking for a balanced LDR solution. I emailed with Tortuga a while ago and found that this is possible by doubling up the parts. But this does not seem straightforward, and I don't see a guide for that. What I ideally need is only one XLR input (could be more though), possibly a buffer (unsure if its needed in my case) One XLR output, Remote control (with display I guess), power supplies.
Does anyone do custom work now?
Yes, you do need a pair of ePot.V3 Max boards for balanced. The reason for this is balanced stereo audio uses 4 channels (2 left & 2 right) rather than just 2 (left & right). Since each Max board only handles 2 channels, 2 boards are required. The rest of our hardware scope (encoder & OLED display etc.) is the same either way so you don't need 2x everything.
That part is straightforward enough but there's no doubt that balanced audio is inherently more complex than single-ended.
A brief overview of balanced audio wiring for the Max can be found in our online product documentation under "Docs". Here's the specific link:

Jacks, power supply, enclosures etc are outside of our scope of supply but are available from countless sources.
