Help - Using Yamaha AVR pre-out to Arcam Amp triggers shut off at moderate volume
Thanks for taking a look at my question.
Breakdown of connections:
I have a Yamaha RX-V775 AV Receiver that I essentially just use as a processor or pre-amp to source AV audio and all video (Smart TV, Blu Ray etc)
Pre-out from Yamaha is connected to Arcam FMJ A19 Integrated Amp, which just has audio input.
The inputs on the Arcam Audio are the Yamaha AV and my PC/ dedicated DAC, which I use for all my digital music etc.
The Arcam outputs to two KEF LS50's. So I am only running a 2.0 system.
For AV, I adjust volume on the Arcam, and keep Yamaha at -8 db (explained below)
Why this setup?:
I like the sound of the DAC--> Arcam with the LS50s (ie. without the Yamaha in the mix). My wife will only let me have 1 set of speakers in the living room, so I need to run both the good audio for music from DAC and AV Audio to speakers through Arcam FMJ.
At moderate volumes, the volume interaction between the Arcam and Yamaha auto-shuts off Yamaha, presumably due to safety feature. Particularly noticable when movies have explosions etc.
I have double-checked that Speaker Ohm settings on Yamaha are set to 8 Ohms - which my speakers are. Arcam doesn't need modification.
I have double checked there are no shortages in all speaker wires including connections between components.
I have unplugged the speakers from the Arcam and played a movie with explosions etc, and the auto-shut off occurs. (Based upon this I have determined that its the interplay between units, not the speakers)
I have fiddled with volume settings on both units. The most stable is the Yamaha at -8db and Aracam at 35 or below, but shut off still occurs at this setting when there's a large boom or something to that effect in audio track.
This auto shutoff continues to occur on pure direct as well.
1) Is there a way to overcome this with the current components and setup?
2) If not - I don't love the Yamaha. Would getting something like a Marantz NR-1510 overcome this? I ask about this unit in particular because my setup is not elaborate, so I don't need many inputs, Marantz is supposed to have good pre amp staging, and based upon user manual, it looks like Marantz auto shutoff deals with heat or shorts, not volume.
Thanks in advance!!
