I just bought the new Sunfire tga 7401 a few days ago. I use my Onkyo TX-NR 3007 as a preamp that connected to this sunfire 7401 via RCA. However, the Automatic Turn-On position doesn't get a signal or turn on the amp. I have to turn the switch to On position to get the signal get through to fire up the speakers.
I did the same wired to my old Sunfire cinema grand, and it is work fine. It is automatic turn on/ off when it get a signal from the onkyo.
So, I wonder it is normal to a new Tga 7401, or there is something wrong to the Automatic Turn-On control ?
Thanks for some advice.
