Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆

Hi I realized my mojo when fully charged blue light to green light lasted only approx 30 mins...and when it hit red only 10 mins toward blinking red before out of power. Whole process seem less than 4.5 hours...is the battery faulty

Bought only for 3 months...hmm. Please advise, appreciate it thanks
It is possible that the battery management circuit needs recalibration. Contact chord customer support, and see what they say.

A simple question: if I connect to the mojo a smartphone lg v20 or an astell & kerm 380 will I have in both cases the same quality of sound?
My experience:
The device itself doesnt matter but different apps sounds different.
Usb audio pro sounds bright.
Hibymusic more bass.
Onkyo player somewhere in between.
With different headphobes I use different apps

Thanks I wanted to ask about this also. I have a tablet with AKM 4376 and it sounds great through its speakers but surprisingly not so great through IEMs. I was wondering the best way to use it to play Tidal through my Mojo.

Any suggestions for this guys? Thanks

Very pleased with this combination of HiBy R3, Mojo and AudioQuest NightOwl as well!
Nice "Sound-Brick", really good usability and wonderfully enjoyable portable music! :L3000::L3000::L3000::L3000::L3000:
Where did you get the green casing from?

I have a line out volume control question.

I'm currently using my chord mojo as a source to a CA-CXA80 intergrated amp. I'm interested in upgrading to a CA-851W which is a power amp with no volume control. The mojo sits next to the amp so for obvious practical reasons I can't get up and walk over to the table every time I want to control the volume.

My question is if I can some way connect a pre-amp before the mojo but still have the pre-amp control the volume? So Pre-amp -> Mojo -> Power Amp, but the pre-amp would still control the volume. I know the mojo's DAC and op-amp are mated together and you can't bypass it like a traditional DAC/Amp combo which is what makes this seem not doable.

I figure that no matter what I set the volume at on the pre-amp the mojo will regulate the output to the power amp to whatever it's own volume voltage is, but maybe I'm wrong about this?

Appreciate any suggestions.

The Mojo will output a fixed volume level based on the volume setting, and should be at least as transparent as any other source component, based on its design. The so called “line out mode” (hold both vol buttons down when turning on) is a short cut to the 3V output setting. This may be hot for some preamp inputs, in which case 4 clicks of the down volume will give you a more traditional ~2V (1.9V), and you can certainly adjust from there.

Question: if you are using a pream between Mojo and amp, where will the preamp be located that will be more convenient? Maybe a longer run from Mojo to amp would work as well?

Well what I want to do is place the pre-amp before the Mojo, so the mojo would be in the middle.

The pre-amp is a combo network streamer that's why I want to place it before and would be the source. I want the pre-amp to then go into the mojo, and then the mojo output to the power amp. If I put the mojo first in the line then I figure the network streamer would use it's own internal DAC and send that to the power amp.

The amp is about 16ft from where I sit and it's just an overall PITA to have it setup that way, I would rather just leave it as is or eliminate the mojo completely from the chain if that's the only way to go about it. But I want to try and keep the mojo running as the DAC if at all possible.

That would work it your streamer/preamp has a digital output, because Mojo doesn’t have an analog input - only digital. Then, you would have to see if the volume on the streamer/preamp was didgital and active in the digital output, or only through the analog output (in which case you would still end up using the Mojo for volume control). Or, alternately, you could use whatever app you are using to control the streamer for digital volume control (e.g., Roon or whatever), for a likely small price in terms of SQ.

Right those were my thoughts. The streamer/preamp does have toslink output, so that would go into the mojo. Even if the pre-amps volume control were digital or analog wouldn't the mojo still regulate that input volume to whatever it's own volume setting is at? And like you said I would still have to control volume through the Mojo's buttons?

I feel like if it has to be done through digital volume control then the loss in SQ would make it useless for me to go through all the trouble of upgrading.

No, if you used digital control on the signal going into Mojo, it would attenuate the volume. Think about your phone connected to Mojo and how you can controls the volume from that. If you are feeding bit perfect to the streamer, the sound quality should not be too bad with th digital volume control, depending on what app. For convenience it may be acceptable, and for critical listening, use the Mojo volume.

Or upgrade to Hugo2 which has a remote or th new TT2 upcoming!

I see, I didn't realize the Hugo had a remote. Unfortunately I wanted to try and make this work with the mojo because I don't want to spend that much for a Hugo. I actually already have a Qutest, but I'm selling it and keeping the mojo to fund the amps/speakers.

Looks like I may be asking for a bit too much from these devices.

The other scenario is maybe I'll end up liking the wolfson dac's on the cambridge audio anyway, but I highly doubt it.

I don’t think think you are asking too much. You just need to find a configuration that works for your use cases. Since you already have Qutest, I would try the streamer digital out (if it has one) into Qutest and see how it sounds. If the streamer doesn’t have a volume/remote, try the app you are using to feed the streamer. It may sound just fine. What kind of sp Akers are you looking at? I don’t know your total budget, how big your room is, or what you like to listen to, but if you posted that, a bunch of people here would likely be willing to offer suggestions.
