Hello !
I received a BOSE Sound Amplifier Basic Audi AS4 amplifier module, I want to use it as a separate amplifier, without optical connections,
I'm interested in whether the TDA 7566 works without I2Cbus - maybe someone has worked with it before without a controller.
Currently, if the module is powered, you can hear the protection relay switching on and then switching off after a few seconds.
Coupling again if pin 27 - Ring-break diagnostic wire is touched.
With audio signal on inputs I have no signal on output regardless of the relay.
I haven't unpacked it yet to take measurements on the IC board.
If I receive an answer from you that the TDA 7566 does not work without I2Cbus, the approach does not make sense anymore.
I don't even know pin 27 - Ring-break diagnostic wire if it's port in or out. It seems to be in.
Also I can not find any wiring for secondary connection (below Audi DSP T32h connector) - except one optical port.
Thanks

If you don't get a definitive answer here, try the chip amps forum:

this amp only works with optical fiber (MOST) and there is also the audi component protection to be lifted
if you want to add an additional amplifier you need a MOST to rca converter example: http: //www.trioma.ru/wp-content/uploads/2017/12/instruction_most-rca2.0_eng.pdf
Maybe you are right. The control should be optical. Analog inputs are already available in Audi DSP T32h connector. Shame I can not control TDA 7566.
to simply add an amp, use the hp output with ca: https: //www.focal-audio.jp/products/customfit/pdf/HiLoV2_technical-sheet.pdf
