Yamaha RX-Z9 Firmware Upgrade???

[smileyone]

You what would be cool, would be to get the euro firmware version so you could enable freekin RDS.

I emailed Yamaha asking about any firmware updates and they said no. This was after the 2500 came out where they had improved the YPAO to incorporate a gui interface, and improved the speed of the whole process.

Now about the firmware I'm sure that they would not give you one period, unless you are some certified repair shop. I mean there are other devices like DVD players for which you can download firmware upgrades. Rotel amoung other makers will let you download firmware updates to enhance their products.

Ahhh freedom number 5

DSP-Z9 Firmware Upgrade ?

Hi,

I have few problems with my DSP-Z9 AV amp. Can any one help me, please ?

The following are the problems:

1)The L/R Balance not at all working. Irrelevant of position, both L & R speakers generate sound regardless of any mode - 9 channel/2channel stereo/Analog/Straight input.

2)Speaker Switching Between A & B some times works some times not. Even when both Speaker sets A & B are not selected, the Amp continues to output thru main speakers.

3)Zone-2 power is always lighted-up

4)Optimizer light is always on.

It seems that these are software bugs in the amp. Have anyone experienced these problems ?

If anybody can suggest solutions, I appreciate your effort.


Thanks & Rgds

Hello,
I also have Yamaha DSP-Z9 , most likely, with firmware error.
Main CPU incorrectly measures voltages from thermal sensors, so fans are always off even after long work time. ADC value in diagnostic menu is 143 for all 3 inputs. According to service manual, all ADC values are percents from 5V ADC reference voltage. So 143% from 5V are more than 5V
All hardware works well. Real voltage on CPU ADC pins are about 1.38V. This is ~27% of 5V . According to service manual , this must be from 5 to 24 %.
There is also "hardware" "half" solution of this error. Original DSP-Z9 fans are noisy 12V fans. So it is possible to change them to 24V fans and supply them from 12V or 16V voltage which are in DSP-Z9 power supply. Main minus in this case that fans are always on, with reduced voltage ( and noise ). It is also possible to make fan control with small additional controller ( analog or with some microcontroller ) instead of main CPU.
But since all fan control is already made , it's better fix it

Another error is : "Zone2" indicator is always on.

I also have service manual for DSP-Z9. If anybody needs it, I can sent.
File size - 30.5 MB.

Can anybody help with service software ?

Best regards
Darius
