Weak Companion/Right Channel on Monoblocks

[Will03]

so far the sound stage expand and more coherence. get closer to d200 now. currenty busy to fine tune my system. but lazy to ask dev marketing guy by email.

btw ive found that the config file can be edited by win notepad by yourself. many setting can be easily read and change without using configurator.

Yes, you can edit the config file in any text editor.  However its content includes a CRC which the amplifier checks before applying the settings in the config file - this is a safety check to prevent mis-configuration that could damage the amplifier or speakers.  So I had understood that changing the file in a text editor (without updating the CRC) would result in a config file that the amplifier would not load.

From what you say, though, either the amplifier is no longer checking the CRC or you have found a way to update the CRC to match other changes to the configuration file.  Please let us know either way.

Thumb you are correct system wouldn't load user edited cfg but there many hints to see their parameters.

Trying around 200 mill sec which is very suitable to me. Using RCA to XLR adapter with Viard silver HD coaxial link cable.

Do you really mean 200 millsec? The config is in microseconds,  0-20000uS (0-20mS) or am I totally wrong?

[Will03]

Still finding the best setting... trying between 100 - 300 in config

Do you mean 100-300 microseconds? The maximum delay that can be set in the configuration is 20,000 microseconds which is 20 milliseconds.

[Will03]

so far 300 microseconds sounds good to my system. but the real measurement is different from 300 microseconds. i think it depends on room accoustic, speakers position and companion unit delays. just pick what sounds the best with your system.

[Will03]

just wonder. how come there is no d800 users complain the delay issue? is that possible devialet fixed in d800 but not d400?

Hi there everyone.

It is my personal experience in last 8 months.

D400 has the similar feeling as less harmony or punch when comparing my ther HIFI gears before.

However D200 sound more harmonized and more in sync with left right channel to me.

Last night i pick up the audionet software to check the delay between left right channel. It is about 4ms which the master is faster on the left channel.

Luckily the new configurator has the delay function. I set master unit delay 350ns. 

Now. You may ask how to set delay with SAM on. It is the secret: 


disable SAM in configurator.
set delay as you want with master unit.
choice you SAM'd speaker again. 
now it is done 

FIXED THE delay problem with companion which causes muddy sound. 
 

Cheers!

Can you describe in detail the software/hardware and method you used to measure the 4ms difference between master and slave?

Thanks

the delay is 0.x ms range.
connect devialet usb input from laptop.
put the mic between the exact center of the left right speakers (you may move your speakers very close to each others). use the software CARMA by audionet or other software to check time response.

if you want to measure frequency response, put speakers back to normal position. put the mic above our seats at head level.

So the delay is not 4ms it is 0.4ms that would make sense if you put in 300us in the config or am I missing something? After you have put in the 300us delay what does the measuring say the delay is? Are you using SAM aswell?

Got an answer from Devialet today but the engineer is not there, but in 3 weeks he is back and I would get a detailed answer about the delay and SAM. But they say now that SAM and delay can not be at the same time, if SAM is selected the delay automaticly goes away.

octaviars wouldnt it be a good idea instead of putting your speakers close together etc to actually measure the time delay from the listening position?

just in case the speakers arent exactly symmetrical
