help with dac mini DIR9001-PCM1793-OPA2134
« on: 25 Aug 2010, 02:50 pm »
Hi all.
I have a problem with this DAC:

http://cgi.ebay.it/DIR9001-PCM1793-OPA2134-Coax-Optical-input-MINI-DAC-/350362124548?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item519335c104

When there is no input signal (digital coaxial or optical) the dac make a terrible noise trought analogic output.
When the signal is present there is no problem and the dac works very fine.

The PIN4 (for MUTING) of PCM1793 is not used in this dac.

The vendor sayed me:
i have contact the factory with the problem
 they replied that it is normal situation .
 it makes noise when there's no signal, but everything will be ok when you listening to the music.
 


For me is not normal... i have never seen a dac with this problem.
How to fix this issue?
