TUAW Review: Kanex HDMI + audio adapter works fine but costs extra
When we first heard about the Kanex HDMI + digital audio converter a few weeks ago, I was eager to give it a trial run and see if it managed to deliver on the promise of integrated audio with HDMI video. I've been playing with the $70 unit for a few days now, and the answer is a qualified yes: it does the job, but depending on your home theater setup you may be able to get by with a less expensive option. The digital-audio Kanex unit ships without a manual and is largely self-explanatory (although the company has now posted a basic user guide and FAQ) -- a female HDMI port on one side of the roughly iPod-sized unit, and three male cables coming out the other side. The cables connect to the mini DisplayPort, optical audio out, and USB port of your Mac; while Kanex does sell a $60 unit that handles audio over USB, this version only uses that connection to power the adapter and does not provide a USB audio interface. If you're running short of open powered USB ports you might opt to plug it into a USB power adapter instead. In operation, there's not much to worry about: I plugged in all three ports to a unibody MacBook Pro and connected an HDMI display, then went to the normal Mac OS X Displays preference pane, where I found a full assortment of resolutions for my enjoyment. The top few 'television' options may vary with your connected gear; on my test set (a Vizio 42" 720p display) I was able to choose 720p and, oddly enough, 1080i and 1080p. Below that you have resolutions ranging from 640x480 up into the 1600x1000 range.
Kanex brings digital audio into a Display Port to HDMI adapter
When we published our "Ultimate Mac mini Home Theater" guide in August, I drooled along with everyone else at the idea of supercharging my HDTV with a mini for movie and music playback. Something nagged at me, though, as I looked over the options for going from the mini's video-out ports (the current model sports both DVI and Display Port) to the HDMI standard connector that most TVs expect nowadays... how to get that digital audio signal onto the HDMI link, and avoid a second set of cables to handle sound? It seemed less than graceful. If you want to skip over a clunky external converter box like this one, current minis and other Macs featuring the Mini Display Port connector now have a new option for HDMI; Kanex's two audio-included connectors can put the sound onto the HDMI link where it belongs. Kanex is selling two models of the connector (both are on extremely limited availability right now, the company says). The $60 Digital Audio version includes a TOSLINK optical connector for premium quality sound, and the USB Audio version delivers analog audio for $50 [as of 10/20, the price has gone up on this unit to $60 as well]. Both let you put all your eggs in the HDMI basket and clear your cable clutter, while simplifying your TV remote input dance as you try to get the audio and video sorted. We're hoping to get our hands on one of these units soon and we'll let you know how it performs. Thanks to Michael W. for the tip.
