Need line out nominal voltage NOT speaker level... 7 Years, 11 Months ago
Hi all -
Does any one know how to modify a UD-10.1 DAC to increase the output voltage closer to nominal line levels?
I have measured the Vrms at .205 with a 440Hz signal at -10db.
I want the output closer to .316 Vrms with the same signal.
I see a jumper J4 on board and many empty traces for the full UD-10 product.
The description says: "The Trends UD-10.1 USB audio converter plugs into your PC or Mac's USB port and lets you connect your computer to your Hi-Fi or Home Cinema system easily, and with high sound quality. "
Unfortunately there is no way that I know of to change the 3.5mm jack to line level voltages.
