Frustrated with my NR-1604
I am also having issues with AirPlay on my NR-1604 recently, though perhaps slightly different than the previous users.
Usually AirPlay works alright from iPhones/iPads/Macbook Pros. No issues with skipping audio. Occasionally there is some difficulty connecting to it initially from an Apple device (e.g. takes multiple attempts at switching to AirPlay on the device before it actually works). However, once AirPlay is started some weird behavior begins.
When it comes time to switch inputs away from AirPlay (to watch cable TV for example), the receiver will switch for a moment (no more than 3 seconds), then switch back to AirPlay and take the volume down to 0.5. It doesn't matter if you stop the music streaming to AirPlay first. It doesn't matter if you choose different speakers on the device you were AirPlaying from first. The same thing happens, every time.
The only way I have found to make it work again is to unplug the 1604 from the wall, plug it back in, and then change input and bring volume back up. Simply powering off with the remote or power button does not help.
Even stranger, the same behavior occurs when powering off the receiver normally - no matter which input it was on. About 2 seconds after powering it off (via remote or power button) it will turn back on and switch to the AirPlay input, with the volume at 0.5.
So then the next time someone wants to watch TV, they have to go unplug the receiver first. It is really terrible.
* I have the latest Marantz Firmware.
* I have done a reset on the Marantz by holding the (I think Zone 2, MDAX, and Power) buttons
* The Marantz is plugging into my wireless router via an ethernet cord
* I have the latest ASUS RT-N66U wireless router firmware
* I have done a factory reset of the wireless router
* The iOS devices are using iOS 8.2 (latest to date)
We use the receiver + TV every day, and AirPlay almost every day.
I have had this receiver for about 10 months (Purchased April '14) and it has been pretty good. However this is just unacceptable and I need to find a fix or get a new receiver. My family hates the thing at the moment. Does anyone know if this is something Marantz would replace or accept a return for under warranty? If not, what other receivers should I look at replacing it with?
