Fusion 8100 Audio level issue

[pallpoul]

I finally found time to set up my Fusion 8100 that has been sitting in the closet for over a month now. I love everything about it, the pq and the sound. Set up was straight forward, having owned many sherbourn and emotiva receivers over the years.

I have an issue with my Sonos connect audio level. it is connected to the 8100 via optical, however the sound level is too low, I have to turn the volume way up on Sonos connect and the Fusion to be able to hear it. That was not the case with the previous receiver to which Sonos was connected to via optical input. (Sony STR DN1050).

Any suggestions or advise please in regard to this issue?.

Thanks

Pallpoul,

glad you could finally setup your 8100, I recall one of your previous posting mentioning the closet :-)

I am using one of the optical input on my 8100 to get the audio from an external HDTV OTA Tuner (the one in my HDTV stopped working...) and it works fine. The only thing I had to do was to boost the gain a few dB, just to bring the level up to that of the other sources (a Roku and BD Player).

Forgive me if I may state obvious steps which you may have already gone thorugh, but going through a mental checklist, this is what I would do in a case like this:

- Check that the connectors at both ends are properly inserted and that no lint, dust or what not got into the connector of the Sonos or the 8100
- Check that the tip at each end of the optical cable is not scratched, chipped or dirty
- Check that the cable was not bent at an angle such that damage may have occurred
- Check that on both the Sonos and Emotiva no setting was altered, reducing the output level or the input gain
- Try the other optical input on the 8100
- Try another cable with the same equipment
- Try the same cable with other equipment
- If all else fails, as a last resort do a complete "Load Default" of the 8100 (hopefully you have not spent too much time customizing the settings....
- If even that does not work, before assuming the optical input is broken, it might be worth considering a re-flash of the firmware. As I described in another post, this is how I resolved a serious issue with Zone 2 volume control.

Good luck with your troubleshooting!

Ty Musichead for taking the time and respond. I appreciate you.
I have tried the coax and analog inputs from the Sonos, they all yielded the same result. The volume on Sonos has to be way up as well as on 8100.
I have another Sonos connect --> XDA-1---> USP-1---> UPA-2---> Def. Techs bp7006's with no such problem, au contraire, I feel I may need to add attenuators as the volume get so loud even at USP-1 dial at 9 or 10 o'clock.

is there a new firmware for the 8100?. if so how to get it installed.

You are welcome, sorry to learn the problem persists. So you are saying that BOTH optical inputs and BOTH coax inputs on the Fusion does not work as they should?

My unit, delivered mid-December (got it from Amazon just before they sold out), came with firmware version ending in .54, I suppose this is the latest one, unless some of the new units being shipped this month are a newer batch with more recent firmware. When I contacted tech support about my problem and asked to have the firmware files, the current .54 and the previous one (just in case it was a bug in .54 that caused my Zone 2 problem), I was told that .54 is so new that they do not have yet the files... So they emailed me version 0.52 and version 0.51 as a back-up. I flashed version .52 and that fixed my problem.

However, I had contacted another member of the forum who has a Fusion 8100 with firmware revision 0.54 and he did NOT have the issue I had with Zone 2 volume control. Therefore, it is likely that if and when I get my hands on .54 and flash that, it will work. It must have been a corrupted flashing when the unit was manufactured, I do not know. What firmware revision do you have?

The firmware installation is not difficult if you have moderate skills with computer. Besides the firmware file, you need a PC program you use to upload the firmware to the 8100 through its USB port. I got all of that from tech support with the instructions. The upload itself take only about 7 minutes.
