If you really want something extraordinary good as an output option in stead of a couple capacitor

Made on my personal specifications by Brian Sowter
Balanced input to balanced or single ended output / Total DDDAC DAC output gain is 12dB or 6dB (optional)

Important:

Only to be used with 4 Decks to achieve low-Freq cut-off of 14Hz (2 Decks will be 28Hz, 3 Decks 19Hz)
For stereo, you need 2 of course 😉

 

Already in the very early days of the DDDAC I wanted to be able to use the PCM1794 to it full content in Mono Mode by means of an OPT. This would give the following benefits:

• Effectively doubling the number of DACs (like doubling the number of Decks in single ended mode
• Lowering THD, as the second harmonic will be almost cancelled out (Like a balanced power amplifier)
• Isolating the DAC from the next stage amplifier
• Offering a possibility to use XLR balanced outputs
• Having a possibility to add gain or make a TVC (Volume control) version out of it. E-Mail me if you are interested – on special order 3 Months.
