DacXP Signature Problem

Postby shaneclare » Mon May 20, 2019 11:24 am

I switched on my system at the weekend and have encountered a strange problem which did not exist before. Now when I change the volume up and down (via the rotary knob or remote control) on each change the sound instantaneously drops out and then returns, once the required volume is reached all is fine and as per normal.

Also the MC-BUS system has stopped working.

From the above I can only deduce that I have a pre-app issue unless anyone has any other ideas.

I'm loathed to return the Pre to Cyrus and the nearest shop is a fifty mile round trip and therefore would appreciate any thoughts or ideas before I get to this stage.

As I say once the correct volume is reached all is fine.

Thanks

Hi, yes I've had a few problems with the DAC XP Sig. In my case the bass completely disappeared.

The process is in the user manual, the relevant bit is copied below. Note that by "remove power" it means turn off completely, not just put in standby. This will delete all your settings.

If you have had a problem with the DAC it is possible this caused the MC-Buss to drop out. I'd treat the two as separate problems though. First do the factory restore on the DAC. Hope it works! Then power everything on the MC-Bus down completely and leave for a while to discharge. Then power it all up again.


Restoring factory settings
You can also restore all configuration options to the initial
default settings that were applied at the factory.
NOTE: This operation is not reversible.
To restore factory settings, disconnect mains power from
the unit. Now re-connect mains power while holding down
the Standby key.

This is the link to download the manual.

My DACXP (not a Sig) does that too! Done it twice now, and the only way to make it work properly is to power it off and on again. I'm struggling to think ~how~ a DAC can suddenly lose all bass - it's a very strange problem...

Might be a good idea to ask Cyrus directly what causes this issue.
