My 8260A installation
I decided to write down some notes about my installation of 8260a because I have used a couple hours to get everything to work as I want and maybe it can help somebody else with his/her exercise.
Naturally the heart of my system is a pair of 8260a which sounds incredible. I really love a clear and natural sound.
I wanted to build a whole digital system thus the conversion from a digital to an analog signal is done only in my Genelecs. This was the main principle. It was also the main reason I decided to build a stereo system. So far it seems to be quite difficult to find out an easy, handy and cost-effective way to get multi-channel output in AES/EBU format. The other key issue was the system has to be easy to use. I also wanted to use my Genelecs when I'm watching TV/movies and playing console games so not only for listening music.
The first thing was to find out a tool for SPDIF to AES conversion. And for this I found out a really handy unit from UK. The MurraysPro's converter (http://www.murraypro.com/spdif-tos.htm) does exactly what I want and it has two SPDIF inputs - coaxial and toslink. It's all what I need because I use my TV as a switch for all sources with motion picture.
The GLM software needs a computer to run on and I wanted to have a real computer instead of HTPC so my selection was a server edition of Mac Mini. And I have been really happy with it. It's small and really quiet. All my music is nowadays in Apple Lossless format so integration with iTunes is seamless. The reason to use iTunes is very simple. It's really easy to use with remote clients. And it doesn't matter which phone you use - in iPhone and Android you can use (iTunes) Remote and in Nokia CuteRemote is really nice program.
Because the outputs from my tv and Mac Mini are both in toslink I needed an extra conversion unit (toslink to coaxial) so I could input the both signals simultaneously to MurrayPro's box. For this purpose I found CYP AU-D2 converter. (http://www.cypeurope.com/Audience/AU-D2 ... erter.html) I noticed that in MurrayPro's box the coaxial input have priority so I don't even have a problem with simultaneous signals.
One big thing is volume control. I have found a couple of way to do it. The simplest is to use Griffin's Powermate. (http://store.griffintechnology.com/powermate) The second way is quite handy when you are watching TV. I have an IRTrans USB infra-red module (http://www.irtrans.com/en/shop/usb.php) which can send and receive IR codes. I use it together with iRed 2 software (http://www.tinbert.com/iRed2/). Thus I can use any of my remote controls to send a signal to Mac to run scripts, key command etc. With these key commands I can change volume via GLM Autolink. The arrangement is not so elegant, but it's really handy. The third option is to use iRed2 directly from your iPhone. Together with Remote this combination it's really effective. I can use 100 % audio output from iTunes and control volume directly in loudspeakers with GLM software. In Nokia phone I use Salling Clicker (http://www.salling.com/Clicker/mac/) to run Apple Scripts (Volume Control directly in GLM software without Autolink GLM). I could use the same software to control iTunes, but I prefer CuteRemote. Its user interface is much nicer.
I have also used Login Items in Mac to open following programs automatically: GLM setup file, GLM_autolink, iRed2 and iTunes. Thus if I have to restart computer all necessary programs are open immediately. Unfortunately I have had some problems with GLM_autolink. I have to open it and then minimize it to get key commands to work. Luckily I can use Apple Script in Login Items to do it automatically.
And my Mac Mini is running 64-bit Lion OS X.
If you have a question do not hesitate to ask.
I would like how the AppleScript looks to automatically minimize Autolink and also the one you mentioned that controls volume without using Autolink?
If you have activated the fader in the GLM window by clicking it (the fader is framed with the black solid line) you can use the following Apple script to change volume down:
tell application "GLM" to activate
tell application "System Events"
key code 125
If you want to get volume up just change key code to 126.
To minimize the autolink window I have used the following script:
tell application "GLM_AutoLink"
tell application "System Events" to keystroke "w" using command down
tell application "Finder"
So far it seems to be quite difficult to find out an easy, handy and cost-effective way to get multi-channel output in AES/EBU format.
this is my experience as well so far. The hardware for a 5.1 solution that could possibly do it is the Lynx AES16 but I have no confirmation so far. I The meridian solution seems to work just with their propriatary protocol. Did you make any progress in that area?
Works like a charm, so far up to 24/96 but it seems 24/192 should be possible.
VLC it so far my preferred player for both films and music up to 5.1 24/96.
