I have a Professional DTS CAD-5 Decoder

I made it that i can use it now with :

LD
DVD
HD-DVD
BLU-RAY

It does not support HD-MASTER but does al the other DTS decoding

There are so many thing you can do with it!

Has 12 analoge and digital outputs for cinema (home :p use)

2x analoge input for cd audio upscaling to 96khz

Also here is the trick. i can make a normal DTS 5.1 set to DTS-ES

And it let me select 44,1 or 48 or 88,2 or 96 KHZ ???

Also Headphone etc etc

Here is the best part of the decoder it will show you how much KBPS the true signal is!

I tested about 10 LD s and they all decode @ 1235 KBPS @ 20MBIT @ 44,1KHZ

If i put in a DVD it will output 686 KPBS @ 16MBIT @ 44,1KHZ

Have not yet test a HD-DVD

Let me know If you wan something tested!

That's wonderful nllaserdiscnl looks great are you going to get a medium size 19" rack and rack mount it as it looks smart.

Shows how DTS and magazines like Widescreen Review misrepresented the bitrate of LaserDisc's and most DVD's. The 20-bit resolution of LaserDisc's doesn't mean that 20-bit sources were used. All the DTS LaserDisc's used 18-bit masters. LaserDisc used the 1.2kbps rate instead of 1.4 to prevent users without decoders being blasted by white noise - the 1.2 rate lowers the undecoded noise rate by 12db.

The first DTS DVD's used the 1.5kbps rate. saving Pvt Ryan was the first DVD to use the lower bitrate. Do you have one of the early DVD's like Dante's Peak or Daylight? I'd like to know what their bit resolution is set at.

How much did the decoder cost you and where did you get it? My Denon allows me to apply DTS-ES to any DTS stream.

I'm watching the blu-ray of Evita and from the sound quality they used the 16-bit 6-track master used for the AC-3 releases - although it's DTS-HD, it doesn't have the fidelity of the 18-bit DTS LaserDisc. Looks like I need to make a DTS CD to sync with the BD.

Yes now i can check the real output, i think i have a old copy of dante s peak. let me check it for you tonight.

A friend of my father own s a cinema and they had this sitting in the back (boxed/Sealed with a price tag/reciept of 3321$ in it!) 07-2005

So i asked him wy they did not used it.he said that it was a wrong order and the DTS firm should pickt it up. but that was 5 years ago so in a heartbeat i offerd him 150 euro's and he said yes and i took it home I see that these are pretty rare as i can't find any info on these baby s

It Also offers output XLR/DIGITAL

Front R
Center
Front L
Rear R
Back
Rear L
Sub R/1
Sub L/2

Did not find dante BUT i found a old copy of pulp fiction DTS dvd and yes @ 24BIT @ 1509 KBPS

Does this mean that the DTS DVD is better sound wise then it's LD version?

Also strange is that a other DVD is saying this:

DTS original intro 24BIT @ 1509KBPS

Then

Movie start Drops to 16BIT @ 1509KBPS

And i have another dvd that is saying 18BIT @ 754,5KBPS

WTF is up with al those diff rates???

For now LD seems the only one that holds a steady KBPS

Looks like they cut the DVD from 1509 early pressing to 754,5 now

150 euro = bargain in my language £124.11. I'm having difficulty finding the pdf file manual on that model. I trust it had manual in the box.
What bit rate does Apollo 13 dts THX Laserdisc show.

yes there is a 87 page booklet with it


Apollo 13 has:

1235 KBPS @ 20MBIT @ 44KHZ

With a High LFE Processing and fast rear surround L t R (peak test)

What does high LFE processing and fast rear surround mean?

Well then, I got keep an eye out for one of these, on the cheap side.

Yes, DTS cut the bitrate to 768 to allow more room for extras or less compressed video - the full 1.5 rate simply took up too much room. Different recordings are done at different bit depths so it's not surprising that the encoding would change to track the master. The high 1.5 Mbps rate on DVD can have better sound than the LaserDisc 1.2 rate - and the 768k rate is much lower in sound quality and doesn't even have flat response to 20kHz - the 768 rate rolls off by -3db at 15kHz.

Unlike Dolby AC-3, which was developed as a system that could handle various rates and bit depths, DTS was a codec bought from an outside company and they kluged on features as required - it was never a 'system' that could handle everything. It was modified and extended as needed - as an example, the first DTS LaserDisc/CD decoders needed a PIC chip upgrade to decode DVD's.

That the LFE peaks verry much and the rear channels have a lot of respond.( 3 sec peak mode ON )

Will upload i pic later

We learn everyday

Yes, DTS for the home was originally a coder called ARTEC developed by the creators of APT-X100 used in theatrical DTS. terry Beard bought it outright and set the engineers on modifying it as needed for LaserDisc, DVD, etc... It was originally designed to be a coder much like Dolby E, to carry multiple channels around a studio without audible losses. The LaserDisc version is the most pure version of the original ARTEC coder.

How have you connected it, it up to the AVR as you'd need a video/mode switcher as it only has so many inputs on CAD-5.

Can you show a picture of the rear of the CAD-5.

I'm interested as well and will put that DTS decoder on my wishlist from now on!

here you go...

just take your sp/diff,coax from the LD,dvd,hd-dvd, etc etc to the decoder and wire up the XLR output to a coax cable and just take the input 6,7, or 8 channel input on your reciever

The wiring/connecting-up looks straightforward. I'm surprised there's no D-25 plug connections on the back expect for 9-pin RS232.
