I would like one that passes the 5.1 signal, so that my
surround system will process it.

Your surround system is Pro Logic or something earlier. Replace it.


Most any amp/receiver with 7.1 or even 5.1 built within the past 8
years should have a digital input.


Since Jamie has broken the cardinal rule of not supplying model numbers
we haven't a clue what on earth he has.

However, if the surround setup is some sort of cheep and cheery
integrated system that includes a built-in DVD player, then there is a
chance it may not include an input for Dolby Digital/DTS carried over
S/PDIF type connections, to connect his TV.

Should that TV have a standard analog stereo output which will include
the original Dolby Surround information from the transmitted film
soundtracks. Maybe there might be smarts inside the surround system to
process that as Pro Logic. Dunno. No model number.

If the system Pro Logic capable, and line level analog stereo audio is
not available on the TV, I think Jamie should be capable, as someone who
has an FCC radio ticket, of wielding a soldering iron and sorting that
out. Or padding down the headphone output.

Or buying a better (and 5.1/7.1) home theatre system based around a
separate amplifier/receiver, and using the digital connection.

I tried the head phone output, that does work also how ever, I need to
pass that through a impedance match amp to properly match that.. It just
does not have the volume level needed, but does work. I may resort to that
since that is a simple project I can through together.

I know this system is a cheapy, but it was a gift. And yes, it's an
integrated system..

I could just simply give it away to my kid how ever, he has the same tv
and it wouldn't work either..

This unit is sold as a Colby 1000Watt system. And take my word for it.
the 1000Watt is a full out lie!.

You don't need to be an electrical engineer to quickly discover this
when you examine the AC mains max demand that is labeled on the device!.

These unrealistic sounding figures are not always an out and out lie - as
such. More the way that they are marketed to the public. For a start, they
always use some proprietry "backpedalling peak music with a good following
wind into 1 ohm" type power measurement, which results in a figure of 180
watts for a channel based on a car radio output IC, that can actually do
about 5 watts RMS on a good day, if you're lucky. Then, they add all the
channels together. So if you have an eight channel amplifier, it becomes
very easy to reach figures like "1000 watts" ...

I recall back in the day, Sir Clive Sinclair bringing out a small IC based
power amp, before the public really understood what a chip was. The power
output for this thing was claimed at some ridiculous figure like 30 watts.
The story goes that this figure had been achieved for 1 second with the
thing cooled in liquid nitrogen, or some such nonsense

Probably the stuff of urban myth, but the actual amp was, I suspect, capable
of no more realistically, than 2 watts RMS.

5 watts is about the figure for a basic amp running on 14 volts into 4
ohms - but most use something rather more sophisticated these days.
There's actually a DIN standard for measuring car radio outputs.

I don't recall ever seeing a home surround system that didn't have
some kind of digital input.

Run the headphone out into the secondary of a transistor radio audio
transformer and experiment with padding the signal on the primary
side. You could do this for both channels once you found the proper
padding. Max signal input is usually 1 volt p-p @ 600 ohms.

According the webpage, it's "1000W RMS", which is obviously a blatant
lie. Looking at it, & based on what the OP has said, I'd guesstimate its
true output at 10W RMS, or maybe (being very generous) as high at 20W RMS.

Depends on what you mean by surround. Plenty of Dolby Pro Logic stuff
didn't have digital inputs.

Surround = 3.2.1, 7.1 DD/DTS

Wasn't really interested in surround until SPDIF / lightpipe was
widely available in the middle of the road home gear.

How would the group react upon learning that Dori is a child beater?

How would they react upon learning that you are a liar, a coward,
