Re: [SlimDevices: Audiophiles] Audio Always On - Transporter option

2010-03-01 Thread Valentino

Audio Always On is also a nice feature if

1) Your Transporter is your preamplifier and you like to switch it
off for display reasons and you don't like that bump.
2) Your transporter DAC drives your tweeters directly.

Re: [SlimDevices: Audiophiles] Transporter: Wordclock in and Processor Loop

2010-01-25 Thread Valentino

I do not _know_ that the Transporter word clock in outputs something.
seanadams says it does not (That also means it cannot I presume).

I might have been fooled into some audiophile truth that wordclock in
is better than no word clock in, also for a DAC. The Meitner and dCS
DACs have wordclock in, right? And they are expensive and good, right?
But they are not data sources and DACs at the same time.

Status: I now have the RME controlling the Behringer's output timing by
Wordclock and the Transporter DAC input by the clock signal embedded in
the spdif signal. And it works. Case closed.

 Hi,
 Valentino: How do you know that 'Wordclock IN' actually outputs
 something, rather than e.g. simply doing nothing? Maybe you wrote it,
 but I couldn't find an exact reason.

That was my initial reaction since the Behringer's happy lights went
all unhappy and the whole system stopped playing when i tried activating
Wordclock In while in asynchronous mode.

Let me add that the reason for using the Behringer is because of web
radio which seems to favour 48kHz. I must have web radio. My hirez-files
are not that many, and I've made 44.1kHz SRC-copies of them already.
On the fly sample rate conversion in Squeezeboxserver would be nice of
course, but AFAIK the server only allows for conversion to 1/2 or 1/4 Fs
depending on Squeezebox model.

What level of jitter-induced distortion can one expect?

[SlimDevices: Audiophiles] Transporter: Wordclock in and Processor Loop

2010-01-24 Thread Valentino

This puzzles me:
I'm using the Transporter's processor loop.

In the loop I have a Behringer SRC2496 sample rate converter and a RME
Fireface UC external USB sound card. The Behringer converts incoming
data to 44.1kHz.

RME is master clock source, and Behringer is happy with that.
However, the Transporter jams the Wordclock signal when I select Clock
Source: Wordclock In.

Alas. Working settings are:

Digital Output Encoding: S/PDIF
Clock Source: Optical S/PDIF (TOSLINK)
Effects loop input: Optical S/PDIF (TOSLINK)
Effects loop clock mode: Asynchronous (External processor is master
Word Clock On S/PDIF Outputs: Word clock output is disabled (source is
master)

Changing to Clock Source: Word Clock Input makes the music stop and all
the error lights on the Behringer and RME dance.


What is happening here? Have I discovered a bug?

 Can you explain in more detail what you want to accomplish?  I don't
 think word clock has been tested in this context, but it's not clear to
 me that what you're doing is a valid application for it either.

Thanks for replying, seanadams.
The basis is that I would like to syncronize the receiving end of the
effect loop to word clock in instead of the clock embedded in the spdif
signal as I do believe that it will reduce jitter in the system.

The loop is as follows:
Transporter - Behringer SRC2496 (converts all to 44.1) - RME Fireface
UC + PC with crossover running at 44.1 - Transporter (- Tweeter amp.)

To clarify: My little digital round trip works fine if the Transporter
uses SPDIF input as clock source, but Wordclock in seems to OUTPUT
something when I select it as clock source.

Okay. I may be getting it if you can help me with a couple more
questions:

Even if the BNC is labeled Wordclock In it is actually Wordclock Out? 
If so: Is the wordclock signal generated from the spdif input
Transporter receives from my RME?

Thanks again.

Trying to rephrase:

Judging by the behaviour of  seems to me that Wordclock In OUTPUTS
something when I try to use it in my application with the RME as master.
Quite unexpected.

I will have to read you replies again (and again probably). Very
educational, thank you.

Okay. So the Transporter just does not like the combo Wordclock in and
Asyncronous mode. I still haven't understood why. Shall reread your
posts.

Thanks again.

Question: To what is your Transporter connected

- Preamp
- Poweramp


ghostrider;428797 Wrote: 
 My system is bi-amped and a pre is my only option.

The transporter's outputs will drive a 600 ohms load effortlessly.
Splitters on the output connectors is a very good solution if you are
bi- or triamping.

(If you're in cable cuckoo-land it might be expensive, but you
shouldn't be there anyway.)
