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

[GreenBow]

Coaxial - Connect using coaxial to an external DAC, to allow DX90 as digital transport.

It is written in the manual.

If you use the 3.5mm output or the Line Out, you are sending analogue signals out of the DX90, usually this goes into an amp, i.e. ALO CDM, to boost the analog signal or sometimes 'color' it.

The magic of MOJO is the DAC, so i will only send digital in. and also MOJO has Coaxial input, Optical input and USB input only. No 3.5mm analog inputs.

Some line-outs transfer SPDIF also. I think that's what people are talking about. My Meridian Explorer has such a socket. I am thinking of testing the Mojo with the SPDIF signal from my ME. I want to make sure it's not a Mojo that hisses on optical or coaxial whichever it is. Very confusing.
 
I am not sure but I think people are saying a standard 3.5mm to 3.5mm jack cable will do it. I have one of those so I could be set up to try it.
 
I think I am wrong here but I hope someone will clear it up. To confuse matters more there is coaxial SPDIF and optical SPDIF.

ok to make it simple, you can't send analog signal to Mojo. But using the 3.5mm stereo cable via coaxial will work.

i have not seen 3.5mm to 3.5mm Coaxial cables. Those i have seen are 3.5mm to RCA. The one i use for Hugo was BNC to RCA.

Maybe it is do-able, since it is just sending digital signals, one positive and one negative.

The jack that comes with dX90 is 3.5mm one end, goes into DX90, and the other end is RCA, so unless one gets an adapter, it will not fit the MOJO. Hugo has RCA on the other end so that will work.

Hi,

Yes that's why it's kinda confusing. Obviously with a Mojo, I'd want it to receive digital in and the problem seems to be that for co-axials out from budget/mid-priced DAPs, there's a little bit of knowledge seeking.

Optical seems to be the way to go though it doesn't push the envelope all the way as co-axials. Another way is of course USB OTG but I don't wish tho use an Android phone at the moment, so I'll probably look for an Android DAP.

Thanks again.

Hi,

I just got my Mojo and try to charge it with the power bank at 1.0 a. The Mojo is very warm. Is that a normal temperature? Then I have tried to connect with Ak100 mk2 via toslink (the one in the left in pictures) but the ak 100 said " optical audio input is connected/ Music playback cannot be controlled when optical audio input is used!" What does it mean??? NO SOUND at all. Then I tried to connect with the 3.5mm connection ( picture on the right) and still does not hear any sound. Why???

Sorry if this has since been acknowledged, went forward a couple of pages and didn't see a response...

Anyhow, the optical cable, the end that looks a bit like a headphone jack needs to go into the HEADPHONE socket of the AK, not the line out (which strangely doubles up as an optical IN for using the AK as a DAC,)

Hope this helps, sorry if already answered.

The magic of MOJO is the DAC, so i will only send digital in. and also MOJO has Coaxial input, Optical input and USB input only. No 3.5mm analog inputs.

The cable transmits the digital signal. Coaxial output does not transmit analogue signals. THE ONLY DIFFERENCE IN 3.5mm COAXIAL STANDARD CABLES IS IN THE SHEILDING AND TOLERANCES. The Mojo accepts the digital signal just fine and it is not analogue signal or it would not work. All the sampling rates are available. The pins in the jack ignore the third pole in a TRS cable. If the sampling rate light (power button) is on that means it's accepting a digital signal.

I have it right here. It's working. It is the Mojo DAC and it is magical compared to the source. The Mojo simply does not accept an analogue input. I suggest you understand a little more about the input of Mojo, the output of coaxial jacks, the transmission of data or try it yourself before you continue posting inaccurate and confusing responses. I've already replied and shown the proof so I'm not sure why you continue to be persistent on a fact you do not know. Not all devices output coaxial signals with an RCA connection and as you can see the Mojo and X5 use a 3.5mm coaxial jack. That doesn't mean it's analogue.

Observe this picture. It's coaxial out from the X5 (not line out or headphone out) and coaxial input on the Mojo. It works, it's cheap, and readily available. You may get RF noise as its not shielded but I hear none whatsoever. First hand experience.



Edit: I should add that this will not work if you want to use the X7/X5ii/X3ii because the pins are different as they all use a shared line out with coaxial out. For that you need the proper cable made, make it yourself, or use the 3.5mm to RCA adaptors. If using the adaptors it's not so convenient, like in the pic below (from my review):

Thank you for your thoughts. I just checked. The coaxial input on the Mojo appears 3.5mm. However the 3.5mm output on my Meridian Explorer is optical SPDIF; (I should have known this: slow day).

It's one signal and one ground. Not voltage like in analogue.

The RCA end is just a different connection. Doesn't mean it magically alters the signal from digital to analogue or vice versa. It's just a connection.

You got the USB C OTG cable from the Play Store?

The C connector termination going into the phone has to be OTG to signal to the phone to be a host, not enough to have an OTG cable in the chain.

There's no more OTG with USB C.

You need a USB C to micro B (Amazon).

Alternatively you can use a USB C to USB A female ("OTG like") cable and the Mojo's USB A to micro B (like you would do with a simple OTG cable).

You certainly don't want to connect a OTG cable in the Mojo.

Thanks everyone. I certainly can connect the Nexus 6P without OTG with the mix of cables currently in my possession. Just one problem, I was so tired last night, I left my Mojo powered on . Grrrrrrrr, so now its charging.

I hope you are able to get it going.  The Mojo is really a sweet sounding portable DAC/Amp that punch way above its weight. 

 

[micropixel]

maybe i've found it..would this be right? ( edit - Just noticed this is female also on the rca end - would need ANOTHER connector to adapt male-male... grrrrr!)

Ain't gonna look elegant but get you your music for now until you are able to get one custom made.

Thanks, but don't worry, as the editor of gavinsgadgets.com , I get to review loads of phones. I have used the Mojo already and it totally rocks Just got the Nexus 6P to review at the moment and its a challenge.

 

[audionewbi]

The cases look great. I look forward to the accessories yet to come.

My hope is chord will eventually release an app for mojo accompanying the mojo extended storage accessory that as been mentioned informally before. I think this will make alot of people happy.

Currently apple sales a 128 GB ipod touch. Together with the extended storage add on this can possibly offer us over 300 GB of storage. we can easily use the camera kit cable which is widely available and honestly that will make it as good as a dedicated stand alone dap.

absolutely right. Ive just ordered one of each, ie the male to male jobby and the female to female.
 
like you say its a clumsy fix but it'll do for now.
 
In all honesty i am AMAZED that the manufacturers of the gear (eg Fiio, iBASSO, Chord, et al), don't give comprehensive options for various connection configs from their accessories departments. Providing the facilities to connect the things together would be pretty high on the priority list of requirements, I would have thought - i know they're competitors but surely there would be room to open a dialogue to get some mutual connections going?

 

[gavinfabl]

Not true, or at least if true strange then that Google sell C OTG cables on their device store.

Edit: checked the store and they are no longer referring to it as OTG, they were a few weeks ago, I checked for them specifically when the 5X and 6P were announced. A matter of nomenclature I guess, with this connectivity being baked into Type C. Link to the ones Google sell here -https://store.google.com/product/usb_type_c_to_usb_standard_a_adapter

Is that the one you have Gavin? As per tests conducted by one of the Google engineers a lot of type C cables currently being sold do not conform to the standard. The cable you have might be data and charging only?

No I don't have this cable, but I have a feeling I am going to have to order this one.
