Connecting a USB interface and mixer to MacBook Pro

[Toby Davey]

Hi, 

I have recently purchased an Allen and Heath ZEDI 10 interface / mixer to use with my MacBook Pro both as an interface for use with recording straight into Pro Tools and with Zoom too. 

The mixer works really well on it’s own (not connected to my Mac) which is great.  

So I decided to plug the mixer into my MacBook Pro via the standard Apple USB C to USB 2 adapter thinking that it would just plug and play. 

The Mixer has a Type-B USB connector on it and supplied with a USB 2 connecting cable.   

i plugged the cable into the mixer and the other end into the Apple USB C to USB 2 adapter.  

Through the mixer headphones I was picking up a lot of interference such as  a sort of clicking noise.  Then my Mac started coming up with notifications that the USB ports had been disconnected because a connected USB device was taking up too much power. 

I have contacted Allen and Heath and they have suggested plugging in the USB 2 cable into another adapter but I only have a few of the Apple ones that everyone purchased when the MacBooks came out with USB C ports. 

They Also suggested that I might not have my MacBook set up properly for external audio interfaces and devices and they sent me a link to a couple of online articles from SweetWater.   

Would getting hold of a type B to USB C cable possibly solve the issue.

Should I have gone with another interface / mixer that would be USB C compatible.  Only really need something with max 4 mono channels and a couple of stereo channels. 

Cheers

Question 1,  did you install the drivers for the A&H mixer first? If not start there and see if that resolves your issue. I have used many usb c to USB-a and usb-b adapters with no issues with various sound cards and mixers so I doubt that’s the issue here.

It’s worth trying a B to C cable. That’s odd though, considering the mixer is externally powered. A couple ideas here: unplug all USB devices, then try the mixer in each of the ports. If that works, start adding other devices. My other suggestion is getting a powered  Thunderbolt USB hub. StarTech is a good bet for reliable ones

Hi, 

Thanks for the suggestions. 

I have thought of getting a USB C to USB B cable and might go down that route.  

I have just ordered a couple of USB C adapters suggested by Allen and Heath.  

If I still get the probelm I will see if A&H would replace the unit.  They did say that it could be down to some settings on my Mac but not totally sure that is the issue. 

If I get no joy with the adapters I might post up to the WhatsApp Group and see what people on the group might suggest. 

Thanks 

Toby

No prob! I use a B to C to connect my Soundcraft MTK12, which is pretty similar to the A&H, with Mojave on my MacBook Pro 2017 in my recording space, and that’s worked for me. Those Apple adapters can be iffy for some equipment in my experience.

Hi Michael and everyone, 

Thankfully I got my zedi 10 mixer replaced and it looked like there was an issue with either the interface or the cable which was causing the connection issues. 

When setting up the mixer in PT apart from selecting the ZEDI in the playback engine settings do I need to make any other changes  of any other settings in the hardware settings or i/o settings. 

Strangely I am finding that the playback channel in the mixer seems to be very high and if I turn the fader for this channel right down I can still just hear some faint sound coming through my headphones which are connected to the mixer. 

Also doing a test recording with a Mic plugged into the mixer which sounds fine through the mixer and in my headphones but when I play back the recorded track back the recording sounds very low. 

I imported a music track which sounded great coming through the mixer. 

Is there something I am missing here?  Am I doing something wrong?

Any advice greatly welcom. 

Cheers 

Toby

Hi, 

Update on ZEDI 10 Mixer issues. 

Looks like I have sorted it all out by a quick phone call and changing some of the I/O settings in PT. 

That should hopefully have sorted it all out for now.

thanks for all the help. 

Best 

Toby
