Hi

Would like to check if having a balanced output for dac is in part of the roadmap?

Will there be any 8 channel ones in the new generation? it’s hard to find good quality linux-friendly multi channel outputs for active crossover use.

Great, I guess I should wait for the next generation. I do not need balanced output at the moment, but maybe you could improve the extendability as well…? (Hint: Audiophonics DAC I-Sabre ES9038Q2M)

:ok_hand: I bought 2 Tone boards because of the Audio Science Review. Don’t forget to send the balanced board when it’s available. I am waiting for balanced board too. Take time to design, we like the best quality for cheap …lol… :sunglasses:

Hi there,

Could we hack the board to add balanced Output ?
You wrote Q2 for Balanced version, and new generation, would you please elaborate ?
Could it be doabble to add Toslink input & digital input selector ?
My goal is to have multiple inputs : I2S, Coax & Toslink
Cheers

Will the Tone Board 2 XLR be a galvanic separation of USB-C from the electronic circuit of the DAC converter?

For the new generation balanced tone board, can you consider providing connection pins to let users power the op amp output stage directly (skip internal dc-to-dc converter) and also add zero-ohm resistors from internal ±5.5V so they can be removed when using external power.

Balanced output should be relatively easy to add - look at the schematic and read Bruno Putzeys’ ‘The G Word’ paper. You need a couple of 100R 0.5% resistors to go between ground and XLR pin 3. Ideally they should be matched to the parallel combination of R50 and R58 for right, an R43 and R57 for left, but that’s probably overkill.

Would be nice to have a version with xlr and optical maybe and a version with just xlr, when you say balanced do you mean xlr outputs?

Would be nice also if there was a cable we could attach so we can add a volume knob to control volume via hardware based and not software based :slight_smile:

Q2 IS 33% over, and updates? I am very excited to try balanced output, I just updated the firmware on my current tone board and ordered a VIM2 Max to use with my old tone board when I purchase the new tone board.

Noise rejection essentially.
