That will work fine, with no issues.

Thank you

Hi everyone.
I have a question. Is it possible to dim the LEDs in Dac-9? Can you insert any foil from the inside? How does it look like?

A faster and convenient way is to use a dark marker pen with fine tip to darken the LED without opening up the case.

Dark foil would cover all holes at once. But is it possible to put this film between LED and case? I haven't opened the case yet.

I have a DAC-9, very happy with it. But, when using my brand new Onkyo cd-player as a transport to the DAC-9 I sometimes get 1 second long sound drop out. Using the coax input. RCA works perfectly. Is this jitter? How do I fix it ?

Hard to say if the problem is with the Onkyo CDP or DAC-9. We have sold over a thousand Nuprime CDT-8 Pro and many of them are used with DAC-9, never heard such problem.

Thank you for your answer. It's a strange problem, never heard of it myself. If someone else here has any experience I appreciate your input.

It could be a "digital handshake" delay.

That means the player, or DAC does not sense and connect to the digital stream immediately.

Not sure of any remedy. It could be a delay in the DAC sensing the stream, the Player not sending, or a weak cable.

You might try switching cables, as well as COAX and OPTICAL.

Thanks John. Must be the cable or the cd-player. I'll try another coaxial cable. It's a shame, because when I use the coaxial input on the DAC-9 the sound is excellent. Just these distracting drop outs...

I had a similar problem. Two sources / amplifiers were connected and when I only turned on the power one, the signal disappeared from the first one. Weird. Could this be a "ground loop" problem !?

Hi all

Does anyone here know the input impedance of the analog line-in for the DAC-9? Thanks in advance.

Cheers.

grubyhalo · « **Reply #331 on:** 16 Dec 2020, 12:05 pm »

Looks like the Input impedance is 470k Ohms, according to Support

You found it! Good.

I spent about ten minutes searching the Nuprime website but came up with nothing for the DAC-9.

Hi everyone , my first post ! My out of warranty dac 9 got smoked due to a power surge , funny it was the only device in my rack that was damaged ,the transformer had a major meltdown , Nu prime was good enough to send a replacement transformer gratis but it got very hot right away so it was unplugged , so indicates a short on the dac board .Are these boards repairable? Replacement boards from Nu prime are almost $500.00 cdn landed so not worth it .Thanks for your time .

You should send the DAC-9 to Aamir to find out what's wrong. Perhaps the power supply is not the only one that got fried.
Was it connected to a quality surge protector ?

Can someone post witch volume number how much voltage level at XLR or RCA has?
I has a Linn Klout amp on RCA at me. I do not want to owerdrive it!

mchase66 · « **Reply #336 on:** 21 Mar 2021, 06:28 pm »

The earlier threads report that 94 is 2V in, 2V out.

Hi!
Tell me, what is the maximum signal strength on the analog input? 3 volts from Chord Qutest won't overload it?
Thanks!

Because of the DAC with headphone amp, so the headphone amp of DAC-10H is more sophisticated than HPA-9 where it has two levels of gain control (H, L and RCA, XLR). HPA-9 only has H and L gain control.

What is the gain control and when/how do you use it?

rustydoglim · « **Reply #339 on:** 1 Feb 2022, 05:50 am »

DAC-9 has no gain adjustment.
