per aggiornare il firmware da soli ecco la procedura (non mi assumo nessuna responsabilità)
HOW TO UPDATE THE TX-SR605
The Firmware update only takes 16 seconds to do and is carried out using a disc (which we will supply) and a CD player equipped with a digital optical output. There are three different ways of implementing the update:-
A] If you own a suitable CD player we can ship out a CD with instructions to you, so that you can update the receiver yourself (remember… it only takes 16 seconds). Alternatively it can be sent via email (please email
onkyo@onkyo.co.uk with ‘605 update disc’ in the subject line AND PLEASE INCLUDE YOR SERIAL NUMBER ) and burnt/finalised as an audio CD on a CD-R disc.
Here’s what you do…
1) Connect the CD-Player’s optical digital output to Optical Input 1 of the TX-SR605
2) Select «CD» at the receiver and change the input to Optical 1 by pushing the button marked « Digital Input »
3) Switch the receiver into ‘Firmware writing’ mode:
a) •Push «Standby » key while holding «Display » key
b) •Push «Tone +»key several times until you see « DSPSR605:XXXXX »
c) •Now push « CD ». In the display you will see the message: S/PDIF UPDATE
4) Now start the CD Player. After 15 sec the display will change to WRITING. If the display does not show WRITING, play the CD again.
NOTE: The vast majority of CD players with optical output will work fine but some players modify the data held on the disc so may not work correctly. In that case please try another CD player. If that’s not possible please use Update options B] or C].
5) When writing is finished «Clear »will come up at the display and the receiver will automatically switch to Standby mode.
6) Check the device to establish if it is outputting sound. Select either a digital or analogue input signal in combination with a DSP mode.
You can confirm that the DSP Firmware version has changed by:-
1. Pushing «Standby » key while holding «Display » key
2. Push «Tone +» key several times until you see « DSPSR605:XXXXX ». It should now read « 07727A ». Push « Standby » to leave this mode
3. Note – if the Firmware version number is not displayed and you see « ?????? » on the display you will first need to reset the receiver by pressing « VCR/DVR » + «Standby »
B] If you can’t or don’t wish to update the receiver yourself you can contact the dealer that you purchased it from and let them carry out the update for you (you will have to take it in to the store).
C] Onkyo will collect it from a pre-arranged address, update the Firmware for you and then return it to you. Bear in mind that because the receiver will have to be shipped to and from Onkyo you may be without use of your receiver for a period of time.
I suspect that most TX-SR605 owners on the forums will take option A] because of the speed of implementation and ease of installation but the choice is theirs.
Unfortunately owners who have purchased their products outside of the UK will have to contact their overseas supplier to make arrangements.
