Alesis StudioDock Pro Audio Dock for iPad - balanced headphone output, hmm

post #1 of 8
Thread Starter 

Came across this from one of my website perusals.


Alesis is not a brand I am familiar with, although I understand they are well established in the musician/studio arena's.


Alesis doesn't go into further detail of what is under the hood.  So I wonder just how the balanced audio output is happening. With the various other connections and uses it isn't a dedicated pure audio route.  


Anything that goes from digital to balanced output is worthy of investigation to me and thought some others might enjoy having a look.


c&p of bullet point;

where does it mention balanced headphone out? the hp outs are on 1/4" phono and although i have occasionally seen the odd balanced line connected this way, it is unheard of ffor headphones and they would be relying on people to either recable their own, or buy perhaps buy a cable from them for the limited range of headphones that have a removable cable. alesis do indeed have good studio lineage and its an interesting move, but the specs are pretty unclear regarding the balanced hp out.

Have a look at the website. They confirm balanced out. There are a couple of reviews and a bunch posts on one of the websites.

It's the combo XLR-1/4" not sure if XLR is output but they say the dual 1/4" is balanced out. Can a combo connector be two separate things? I do not know.

I see another adapter in my future.

no they dont, on the product page they confirm balanced XLR/phono combo line/mic INPUTS and 'balanced' LINE OUTs on 1/4" phono, the headphone out is single ended on a single standard 1/4" phono jack. its still pretty cool and would team up with a balanced portable amp, or a dac/amp via usb pretty nicely for a killer transportable rig with better spec than either CLAS or fostex. yes you can have a combo jack, theyde be neutrik, but they are not outputs

pity, it actually doesnt seem to have any optical or coax digital out, hopefully the usb works as an output

was basing my reply on the faq



Are the iO Dock's ¼” inputs and outputs balanced?

Yes, the iO Dock's ¼” inputs and outputs are balanced, TRS connectors.
and this comment in the gear junkies review comments:

Hi everyone. Alesis here. The 1/4\" output connectors are indeed balanced TRS

 hope that helps.
