MAIN/DSP Update Procedure-2

[NOTE: See MAIN/DSP Update Procedure-1]

*Combination of "MAIN_FW and OSD_FW” has limitation.    

*OSD FW cannot be updated. 

Preparation for Update

1. PC（Personal Computer） which can play back wav files and output digital audio signal under Windows XP.

2. Software：Given wav-formatted FW Store it in the PC in advance (PC Update) or burn a CD-R with it as a music disc (CD Update).

3. Connection: DIGITAL (OPTICAL/COAXIAL) ourput of PC/CD Player --> DIGITAL (OPTICAL-1/COAXIAL-1) INPUT of TX-SR608 etc.

* PC needs to be able to handle wav files and output digital audio signal.
* For wav-compatible PCs which do not output audio signal at the above specification,
use a commercially-available USB-AUDIO interface unit. e.g. Onkyo-made ND-S1

* PC needs to run Windows XP. Windows Vista and Windows 7 do not work.
* Set wave Volume to Maximum including Volume Control in Control Panel.
For further information, please see Owner’s manual of your PC.

Control Panel

--> Sounds and Audio Devices

--> Volume tab

--> Advanced

* Instead of PC, CD players with DIGITAL output terminal can be used.

--> Turn all the levels to Max.
Note: CD players need to output digital audio signal .
Some CD players and DVD players are not suitable for update because they process audio signal to output.
Burn a CD-R as music disc.

When another try results in failure again, use the other update method.
<NOTE 2>
DURING FW UPGRADE,DO NOT TURN OFF THE UNIT. DO NOT REMOVE ANY CONNECTIONS.
These operation will not allow FW Upgrade any more, andthe whole board or IC will need replacing.
