Hello
Mr Paul Tessier, in this diyaudio thread, show a merge of the digital
CS8412 section of a NOS dac with the shift register part of the Cambridge
DAC3 schematic who do some shift registering to give 4x oversampling. I
find that this schematic could be quite easy to made.
http://www.diyaudio.com/forums/showthread.php?postid=1638842#post1638842
Anybody know if it would work correctly, without the 7220, in a
non-oversampling mode, and give the correct timings/shifts and bit clock
shifting result ?
Making a test board, how can we see on a scope, if, without the 7220, this
schematic do give the correct timings/shifts and bit clock shifting result ?
Thank
Bye
Gaetan

I've bought a cheap amp that said "AC3 input" in the manual. On the back are 4 sets of inputs. 3 of them are standard dual phonos, marked tape, cd, and tuner (left and right of each). The other is marked AC3, and also has two phono sockets (marked left and right). I was under the impression that AC3 was the bitstream format of dolby surround sound and required only ONE phono connector (or an optical toslink connector). Why do I have two phonos? I don't have the ability to give it a dolby bitstream yet to test it (waiting on a part), but I did try connecting a standard stereo analog input to the AC3 phono connectors, and it worked. Should it have? Could it be an analog/digital input?

A laser is a device that emits light (electromagnetic radiation)
through a process called stimulated emission. The term "laser" is an
acronym for Light Amplification by Stimulated Emission of
Radiation.Laser light is usually spatially coherent, which means that
the light either is emitted in a narrow, low-divergence beam, or can
be converted into one with the help of optical components such as
lenses. Typically, lasers are thought of as emitting light with a
narrow wavelength spectrum ("monochromatic" light).

I am looking for a set of manuals for an EAI 1000
analog computer that I have just inherited. Does
anybody know where I can find them?
