Hi everyone, I was very excited about this new purchase, a less than a year SP2 with the small 2BSST amplifier to drive my egglestonworks Fontaine II.

I'm experiencing issues with my sp2, hope someone can help.

The most annoying one is the digital signal detecting, is there a way to deactivate it ??

I'm using the SP2 all digital and I have a distinctive small "click" sound on the speakers - the one I got when I change source and I don't mind - but I got it at the end of every single track of a CD !

So it's becoming painful to listen music, which is a major problem, you can guess.

I have the same problem within a game, or watching movie, every time the digital signal drop and SP2 is detecting it again.

The other one, less annoying, is the volume control difference when switching from bypass to stereo (2.0 listening). It's always louder when I switch to bypass 2.0, is it normal ?? I guess not.

Thanks in advance

I have the older SP1, which has the same issues when switching between digital sources etc. I am surprised that SP2  would lose "sync" with the CD player between tracks on the same CD however? I would be interested to find out if it does the same thing with another cd player or perhaps when you play a cd via your  DVD player?

To ensure the SP2 remains in digital and doesn't switch to analog when there is a digital loss, you should ensure that input has been set to "Digital Lock" by using the code 061 (mute, stereo, thx).

Then you should adjust the digital loss delay code for a time that satisfies the source on that input. The delay feature delays the signal from being processed from 0 to 3 seconds in 1/2 second steps to remove the click between changing channels on a SAT/Cable box or gaps between songs on players that drop out.

The code for that is 093 (mute, save, dolby). It's default is 0, so the first time you enter the code it will show 0.5 seconds in the display. Each successive entry of the code will increment it up to 3 seconds (and then loop to 0 again). If you get too long a delay, you'll miss the start of the songs on your CD, so you have to fuss with it a bit.

BTW, I don't believe true CD players drop out between songs, as the assumption is that each track will be PCM As opposed to DTS, AC-3, etc). This may not be true of a universal player.

ok thanks for that, I'll try the code, what should I choose exactly with the 061 ?

It does it whith every single track from a squeezebox, even while listening to webradios, also when playing a movie, in the menu or in every game etc. So many times a day, I really can't enjoy it ! I had many many pre/processors over the year and never had this kind of issue.

It does it also with coax (squeeze box) or optical (dvd player), especially when I pause cd or dvd : it shows : sgnl detecting and just before that I have the CLICK, when I play back I don't have it.

I've just tried playing a cd from PS3, it doesn't lose signal between track, so no click until I pause or fastforward...

Thanks for the help

Edit. Ok I just tried the 063 code, it says : force digital signal, ok, do I have to validate in a way ? Because it didn't change a thing. I'll try the 093 now

Edit. I changed the setting, went for 1.5sec, it works, for the one track I just heard, no signal loss mean no click  thanks BUT of course I have it each time I pause or change tracks ! There is no way to change that ??

[brucek]

what should I choose exactly with the 061 ?

The 061 code turns "digital lock" on, and 062 turns it off. This feature stops the processor from looking for analog if the digital signal is lost. When "digital lock" is on, it will still go to signal detecting mode when the digital signal is lost (after the variable delay time).

I had many many pre/processors over the year and never had this kind of issue

Well, you just didn't know that it was happening with those other processors. The SP2 shows you that it's in the signal detection mode in the display screen, so you'll know. Other processors just don't happen to let you know that it's happening. Yes, I'll admit, Bryston could have chosen a quieter relay - I've learned to ignore it.

It's essential that every digital input to any processor has to enter signal detection mode once the SPDIF bitstream signal is lost. The decoders are always monitoring the incoming signal to know when they might need to switch to PCM or AC-3 or DTS decoding. When the DSP detects any change, including lose of signal, the volume controllers are muted, and the bitstream detection and mode switching routines are started. If this didn't take place, and it allowed DTS to be decoded as PCM for example, it would sound pretty horrible. A CD player between tracks will output digital zero in PCM, so you don't get the dropouts there.

But, when you switch menus in a DVD, or pause a DVD, or change channels on a STB, the signal is lost and all the nonsense I describe above takes place. If they used a quieter relay, and didn't show you that the detection routine was running in the display, you'd never know it was happening.

You're going to have to learn to live with it. I would advice increasing the delay a bit, and short dropouts will be ignored (i.e. channel changing, etc).

James,

btw...this can be a serious problem: WHAT if you get retired one day? are you going to join us here anymore? if not...who is going to follow your footsteps?

ok brucek, thanks very much for this detailed answer, I get it so no solution when changing track or playing a game or... I hope I'll be able to live with it, we'll see with the delay change.

Any idea about the second issue, the difference in volume between stereo and stereo bypass analog volume ? As I can see James is here, i may get double feed back

Hi damned,

The difference in volume is correct.  We use two totally different volume control paths in the SP2. One is totally analog with a stereo volume control in Bypass  and the other is through the processor in the digital circuit.  There will always be some difference as the analog control will have more gain (volume) than the digital control for a given setting.

By the way the CODE settings are specific to EACH input.

Hi James, ok so this is normal also.

Yes I did save this delay setting for all inputs, thanks.

Ok as everybody's here, can I ask advice about cables between 2BSST ans SP2.
I'm using XLR sommer galileo 238 and as I have no experience at all in xlr cable, I wonder if it's the wise choice, any advice here ? I'm especially looking - no idea if it's even possible by changing cables - to have a less "thin" sound.

Thanks

[James Tanner]

Cables can change the balance but it is usually done as a 'fine tuning'.  If it sounds thin then I would first look at speaker/room positioning.

Hi Al,

I am contacting brucek and will ask him to take over.

[CDinsmore]

Thanks damned for bringing this up.  I was having the same issue and thought I might have to send my unit in for servicing.  I was able to enable the digital lock using code 061, but my unit does not seem to respond to code 093 (plus it isn't listed in the owners manual).  Am I doing something wrong?  Also, could someone explain what code 091& 092 (Chatter detect on/off) do? 

Thank you!

[James Tanner]

Hi,

Chatter is another option to try and reduce the click sound. Most of these were codes added after the manuals were released so some may not appear in the manual depending on the vintage.

The 'click' is because the source is loosing the digital signal during changes. It does not happen with sources that do not loose lock or disrupt the digital bitstream during changes.

[CDinsmore]

Thanks James.  Any idea why my SP2 doesn't respond to code 093 that bruceck mentions?

Sorry not sure on that one other than maybe the software is an older version.

james

[CDinsmore]

Sorry for all they questions, but is the software updateable via a firmware update?  I looked on the Bryston website, but couldn't find anything. 

Thanks again.

No problem - contact Mike Pickett at Bryston and he will assist you - mpickett@bryston.com

Would someone provide me the procedure with how to enter these codes? 

What is the recommended delay time to set?

Thanks, JohnnyB
