Did you try and get it from Onkyo? You have to register your receiver first with Onkyo to gain access to the DSP firmware... unless that link is totally expired now. But, even so you should be able to call or email them to get it. Here is the actual DSP firmware link for the 705 that you can use once you have it registered:http://188.8.131.52/download/firmw...re_replace.cfm
I would hope that would work. You should be able to download the actual small file and these instructions:http://www.filedump.net/dumped/dspup...1223284303.pdf
Ideally what you need is just a CD player with an optical output. Next choice would be a standard DVD player that is set to bitstream out. Before you do anything though, you should just check to see what level of DSP firmwares you are currently running on your 705. Follow this:
To check the DSP version, Press and hold "Display"
button and then press "Standby/On" button. You will see Main X.XX/XXXX
front display. Within 4 seconds after the Main X.XX/XXXX
displayed; press Tone
"+" or Tone button. F/W version of first DSP will be displayed. Press
(within 4 seconds after first DSP displayed) again the Tone "+" or Tone
button and you will see the second DSP version. Now, Press (within 4 seconds after
second DSP displayed) again the Tone "+" or Tone button and you will see
the third DSP version. The new versions will be as follows:
First DSP: 08214A
Second DSP: 07518A
Third DSP: 07820B
If your firmwares match these of the update, you may as well not bother. Then I would just call Onkyo and see what they say. If you find that you do need the update and can't get it, PM me and I think I still may have the old CD-R I burned to do my update..... Good luck!
