Sony PCM-F1

Sony PCM-F1 (16 or 14-bit EIAJ at 44.056 ksps, NTSC or PAL output, 2-channels simultaneous encode and decode, $1,900 new in 1982, about $100 used in 2016). I got serial number 10 in April 1981 direct from Sony, and I've gotten two used later at this link directly to them at eBay (see How to Win at eBay). bigger.

Zipper noise is audible at 4 Hz.


It's premphasized. For play-in from a CD player, set 0 dBFS from a 0 dBFS 8 kHz sinewave.

1 kHz too low, and a 1002.7 Hz square is too much.

Once you've done this, the CD-1 fade-to-noise has some distortion at 0:06 at 14 bits, AOK to 0:15 at 16 bits



Dual 24-segment meters rear premphasized digital signal.

Infinite peak hold.




Line output @ 0 dBFS: 0.725 V.



Phones output @ 0 dBFS:

192 mV @ - 24 dB

379 mV @ - 18 dB

0.74 @ -12 dB

1.445 V @ -6 dB

2.755 V @ 0 db



AC-700: 5.2 W off, 6.65 W on but unconnected, 8.0 W connected but off, 34.6W operating cold, 32.6 W warm. No change with signal.

+ is towards heat sink, - is towards audio connectors

Help Me Help You

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 when you get anything. It costs you nothing, and is this site's, and thus my family's, biggest source of support. eBay is always a gamble, but all the other places always 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!
