Why does the Mojo have 2 USB inputs (Input + Charging)? Is it so you can connect to computer without charging?

Because one is for charging and one is for data input. In audio applications it's best to keep these two things far away from each other.

Yes. It's best to not leave lithium batteries plugged-in and at full charge all the time as it's very stressful for the chemistry.

Yes, you can use it using only the input usb on computer.

Thanks for the responses.

For using the Mojo as a DAC, some reviewers are saying use 2 Volts (Volume Double Blue), instead of 3 Volts (true Line Out mode). Argument is less distortion. I don’t need a lot of volume for my Line Out purposes.

Thoughts?

4 clicks down is 1.9 V. You might even need less depending on the input sensitivity. You can experiment, or know it you have the spec for input sensitivity.

Not sure if this has been suggested before..a quick and dirty (and cheap) method of finding whether you are affected by radiated EMI/RFI and need shielded cable(s)..(especially if you find the Mojo sounding the same as other dacs or screechy)
Wrap your whole USB cable from end-to-end (i.e. from Mojo chassis to player chassis) in aluminum foil (used to wrap food). You should notice an immediate change if there is EMI/RFI interference..

I think for most of us damage to the signal comes from the source and less so externally as most decent cables are already very well sheilded.

Would like to agree with you..however,sometimes a small cable like an unshielded OTG cable can cause problems..also,it's a cheap test and worth trying..

I think sometimes we look for problems and then we find them ... my Mojo sounds amazing, and I don’t need no aluminum foil to tell me that.

I had a problem with radiated EMI/RFI which made the Mojo sound ordinary or bad. I just want to help people facing the same problem..

So I know that 2 Volts (standard for Line Out) is Blue Blue.

But how do I know when it's really Blue Blue? I guess it doesn't have to be exact, but is there any indicator of when I'm actually at 2 Volts?

Its mentioned here, the fixed 3v is just a preset and 4 clicks down to 1.9v, theres no actual mode so adjust the volume as needed.

Ok one more question. From the manual:

"Sample Rate Setup
Open the Audio MIDI Settings options (Application – Utility - Set Audio MIDI).
Select the Audio Output tab in the Set Audio MIDI.

Select the desired sample frequency from the options given."

I have the option to set the rate from 32,000 to 768,000 Hz. Standard was 44,000.

What setting should I use? Streaming Tidal from Desktop up to Master Quality.

Have you checked the FAQ in post #3?

As an alternative, someone could just answer the question.

Someone nice on Reddit said:

"Let Tidal set the sample rate. When selecting the output device there should be an advanced settings option that allows tidal to output bit perfect to the DAC."

I don't know how to do this. I found an Output option in Tidal that I set to Mojo, but I am still seeing the color on Mojo locked at whatever rate I set in the Audio Midi Setup application.

How do I do the "output bit perfect to the DAC" thing?

Please help a newb!
