Hi I’m considering buying UR44 and have some questions.
1 Can you turn down or mute the main speaker output when you use the headphone?
2 Now I’m using Edirol UA 101. Will the UR44 be better or worse sound quality?
hope somebody can help?
I can answer question 1 for you.
Yes, you can turn down the main output on the front panel of the UR44 and the Phones 1 and Phones 2 outputs on the UR44 still provide output.
The main output can also be muted from the dspMix software (I’m running on windows 7 64 bit) but this also mutes the headphone output. However, you have access to 2 separate mixes via the software, Mix 1 and Mix 2, so it is possible to mute the main outputs of Mix 1 and still have a headphone mix available through Mix 2 (as long as the headphones are connected to Phones 2 output).
Hope that is helpful. I have only had the UR44 up and running for a few hours so I am still learning how it functions and how the mixes are available via a DAW (Cubase).
Cheers

are there 6 individual outputs on rear panel ? 1-2 3-4 L-R ?
Surely if you can find your way here to ask that question, you could easily find your way to the Steinberg shop and find the answer yourself.
Didn’t Ask it right, I’ll try again 
obviously it has 6 phisical output jacks,but it also says on specs 6*4 in/out ,so it confuses me.
It’s actually can send 6 mono or 3 stereo separate signals/cue or L-R outs are mirrored to other 1to4 output.?
There are 2 “Mix” output option that can be set up using the supplied dspMix software.
Mix 1 feeds the Main outs and also Outputs 1&2.
Mix 2 feeds Outputs 3&4.
There are also the option to tap the Phones 2 output from either Mix 1 or Mix 2.
The Main outputs are specified for connecting to monitor speakers whereas Outputs 1-4 are to connect to external devices at line level.
Does that clear that up?
Cheers
Stevo…
Yes
