Measured with the Rohde &Schwarz UPL. The traces are color coded for the Left Channel and for the Right Channel. When they don't lie on top of each other, it's due to channel imbalance.

Measured analog-in to analog-out, 16-bit encode-decode via NTSC video mode:

DAC THD vs. level, no deemphasis.


Sony PCM-601

DAC Right Channel phase relative to left, no deemphasis.

As expected, it's expecting inputs from a time-multiplexed ADC, so fed a more modern signal, the Right channel is delayed about 12.1 µS from the left, the same as moving the right speaker 2/3" (16mm) further away from your ear.


Output Levels


Full analog-digital-analog feedthrough, with demphasis at 1 kHz:

Output at 0 dBFS: 1.340V RMS left, 1.377V RMS right.

MOL at 0.1% THD: 1.358V RMS left, 1.391 V RMS right.


Fed from digital source, no preemphasis

0 dBFS = 1.4017V RMS left, 1.4353V RMS right.



at 0 dB FS, digital in, no demphasis 0.00094% left, 0.00175% right.


A-weighted output noise

left: 80 uV (-81.99 dBV) RMS, left: 37.7 uV (-88.55 dBV) RMS

(14-bit: left 86.5 uV (-81.22 dBV) RMS, right 49.65 uV (-86.27 dBV) RMS)



PCM-501ESD was similar, minus the SPDIF interfaces.

Help me help you         top

I support my growing family through this website, as crazy as it might seem.

The biggest help is when you use any of these links to Adorama, Amazon, eBay, B&H, Ritz, Calumet, J&R and ScanCafe when you get anything, regardless of the country in which you live. It costs you nothing, and is this site's, and thus my family's, biggest source of support. These places have the best prices and service, which is why I've used them since before this website existed. I recommend them all personally.

If you find this page as helpful as a book you might have had to buy or a workshop you may have had to take, feel free to help me continue helping everyone.

If you've gotten your gear through one of my links or helped otherwise, you're family. It's great people like you who allow me to keep adding to this site full-time. Thanks!

If you haven't helped yet, please do, and consider helping me with a gift of $5.00.

Thanks for reading!



Mr. & Mrs. Ken Rockwell, Ryan and Katie.
