Hi,
I am facing a weird issue with my AVR Marantz SR6015 that goes in protection mode randomly.
It always powers up and operates correctly up to random and sudden loud pops in speakers followed by the device going in protection mode.
This issue started 1 weeks ago.
I had my setup in its current configuration for 2 years (except the addition of 2nd sub 2 weeks ago).
I moved in a new house 2 months ago but it is the same setup.
My configuration is hybrid : HC (5.2) and Music (2.2).
Both mains and subs are used in both configuration.
For music:
- streamer Node2i -> (toslink) -> Preamp/DSP Minidsp Flex unbalanced -> (RCA to XLR) -> power Amp boxem 3409
- Boxem ncore amp is feeding my 2 main speakers (Magnat Quantum 759 TOTL).
- Minidsp Flex feeds 2 SVS SB1000 pro (RCA)
For HC:
- Internet media box -> (hdmi) -> AVR Marantz SR6015 -> (hdmi) - > Android TV
- SR6015 powers center and surrounds channels
- I am using the SR6015 fronts preouts (RCA) to feed the minidsp Flex unbalanced for front mains
- I am using the SR6015 sub outputs to feed the same SVS sb1000 pro subs (RCA).
I accessed the protection history mode of the SR6015 and it shows few protection mode events with the cause 'DC'.
Googing a bit, I found out that some similar issues were reported (with various cause such as defective power supply, hdmi card,...).
I naively tried to isolate a potential configuration issue.
I removed all connections from the AVR and tested reconnecting stuff step by step.
So far, I concluded the AVR behaves correclty (no protection mode for 1 week) when connected with hdmi and speaker level outputs (center, surrounds).
Then, today, I reconnected the front preouts to the minidsp Flex. I got a protection event this afternoon.
When the issue first occured 2 weeks, I thought it could be related the 2 subs.
Thus, it seems the issue occurs when something (minidsp flex) is connected to the AVR preouts/subs RCA outputs
Any ideas or advises?
Is there anything wrong is this setup and wiring? Or the unit has a hardware issue?
The worse thing is the SR6015 warranty ended only 2 months ago ( I bought it 2 years ago)
Thanks!
