PCM to analog converter?
Silence Seeker
I can find lots of products converting stereo analog (RCA inputs) to
PCM digital.
Such as the products here http://tinyurl.com/652t8 or here
http://tinyurl.com/6qyvz.
But I am looking for an end-user product that does exactly the
opposite: convert standart PCM (as in the output of my DVD player) to
stereo analog (2 RCA outputs). It doesn't have to be high end. It
could be the same level/quality as the Radio Shack signal converter
(http://tinyurl.com/6qyvz).
Where do I find such a product? Any recommendations?
Thanks,
Sam

If it's for your DVD player... why don't you just use the analog outputs?
Or feed the PCM signal into your home theater receiver (or any receiver for
that matter) and you can get the analog signal through your pre-outs. If
you have no-preouts... you can get the signal from the speaker level
outputs - just get a speaker level to line level converter.

Well, my DVD player can output either PCM *or* analog at any given time,
but never simultaneously. I have this special need of feeding the output
of my player to another analog device while it is playing through my
DENON AVR-1601 receiver, which does *not* have pre-outs for digital input.
My particular situation is somewhat complicated/unique and if you are
curious, you can read about it in an older posting of mine:

I am just trying to find a low cost solution to a stupid problem created
by the fact that DENON chose to *not* provide pre-outs for digital
inputs (no need for another DAC in the product, just wire to an extra
RCA jacks the same analog outputs that go from the the DAC to the
amplifier...)

I guess I will have to check that option, but just in case I can't for
some reason, do you know of any product that converts PCM to analog?

PCM to Analog is basically what a receiver does ; )
Anyhow, if you're looking for a speaker level to line level device... I
just happen to have an extra one for sale. It's a SoundGate Interface HTLOC
- it's used to convert the center speaker channel to line level so that you
can use your TV for the center channel. I believe the device is rated for
100W.
Otherwise Crutchfield has a similar device for mobile audio which is rated
for 30W.

You are right - a receiver does this among many other things. However,
I am looking for a device that is much less expensive, smaller and
most importantly - consuming much less power than a receiver.

Are you referring to a device like the one described here?
http://www.hut.fi/Misc/Electronics/circuits/speaker_to_line.html
Is your device superior to the one described in the provide URL in any
way?

Yes it is similar to what that circuit does. The device I have can
handle 100W.
Here are some pictures of the device:

http://members.rogers.com/mshe/IMG_2216.jpg
I used to use it to convert my rear surround speakers into a line level
signal for use with wireless spakers.
The text on the device says:
Home Theater Center Channel Adapter (03HTLOC)
The SoundGate HTLOC creates a pre-amp level singal that allows a TV's
internal speakers to be used as a home theater center channel speaker
system.
Here is a similar devices you can buy online but is rated only for 30W:

If you're interested in my device, you can e-mail me at

If it has digital inputs, that is! What you seem to be looking for is
a D/A converter, of which there are many, designed to be connected to
CD transports or other digital sources.
The above based on that by PCM you Pulse Code Modulation, i.e. a
digital sound signal.

Per, thanks. The speaker to line level converter suggested by Tam is a
cool idea but unfortunately doesn't fit my needs, since there are
scenarios where I want to get signal to my analog devices while the
speakers are turned off.
So, back to square one: do you have links/URLs to specific such
products (i.e. "D/A converters"). I am not looking for a chip, but
rather a complete product that is packaged conveniently to receive an
RCA PCM input and output 2 analog RCA outputs. (the days where I had
the time to build something like this from scratch are long gone...)

Depends on your budget/needs. You could start at eBay and might find
used AudioAlchemy and MSB DACs starting under $100. If you wnat
specific recommendations at an order of magnitude or two more bucks,
email me. ;-)

I believe that most high-end audio salons will be glad to sell you
one. Be warned, they're mostly sold to the carriage trade, and hence
have high prices and (in some cases) less-than-stable manufacturer
reputations attached to them.
Another option is to go to www.cirrus.com, and look up their Crystal
Semiconductor DACs (they're listed under mixed signal, audio/video,
stereo DACs). They have a lot of single-chip converters, and for many
of these they'll sell you a fully-populated evaluation board (e.g.
SPDIF in, stereo analog audio out). Add a power supply and a case and
you're good to go. I believe you can get similar eval boards from
Analog Electronics for their DAC chip - ditto from Wolfson Micro.

You should fid such a product just behing the audio output sockets of your
DVD player.
