Ejecuté Audyssey con los monos V3 conectados para L/C/R en mi sistema 7.2.4.

Con un ajuste de ganancia de 25 dB, Audyssey tuvo que aumentar los ajustes de L/C/R en 4,5 dB.

Con una configuración de ganancia de 31dB, Audyssey estableció los ajustes en -0,5db (mucho más cerca de lo que son el resto de mis ajustes).

¿Debería quedarme con 31 dB? Estoy usando entradas RCA en los Fosi Monos.

I ran Audyssey with the V3 monos hooked up for the L/C/R on my 7.2.4 system.

With 25dB gain setting, Audyssey had to boost the trims for L/C/R by 4.5dB.

With 31dB gain setting, Audyssey set the trims to -0.5db (much closer to what the rest of my trims are).

Should I stick with 31dB? I'm using RCA inputs on the Fosi Monos.
What speaker do you have? I have a Central Rs6 audio monitor that recommends a maximum of 130 watts 6 ohm and I don't know if I can connect them to the pre-out of my Denon without problems. Thanks
 
A month?? Why such a long time before they ship?

This is probably our fault for making a big noise over not meeting expectations for delivery on the first starter. They seem to have taken those complaints seriously so quite likely they are playing a bit safe on the second batch - and it is a second batch not yet a continuous production with available retained stock so a longer lead time is likely to be needed.

So what gain setting are people using with these?

Generally the lowest gain which still can deliver the maximum volume you want.

I'll be using XLR though which only has a single fixed value, although that is nice and low.
 
Minor update on the deceased amp.
Replacement has been shipped.
I'll return the broken unit so their engineering team can do some forensics.
They would let me know what part was responsible.

Hope this replacement will last, or it will be my last Fosi.
 
Ali has a good discount on coupons now. Is it worth buying this version? https://www.aliexpress.com/item/1005007310872364.html
Pay very careful attention to the What’s In the Box graphic when choosing. The first one is amplifier only with no power supply. The fourth one is TWO amps plus power supply and power supply filter. The two middle options are just one amp plus a power supply.

The single amp with 10A PSU is a terrible deal compared to the other options!

Likely due to international postage pricing set through Universal Postal Union (UPU). At least in Norway it reduces shipping costs for Chinese companies drastically, as Norway Post has a cap on how much they can charge for handling mail from China.
 
@Fosi Audio,
when will you deliver the power filters, they are already available....



THX!

"Hi

Thank you for your continued support of our project. Due to some delays, our power filters will not be available for shipping until after the 15th July. We would like to know if you prefer we ship your other items now, or wait and send everything together once the filters are ready. Your feedback is invaluable to us, and we appreciate your patience and understanding as we work to fulfill your order.

Looking forward to hearing back from you soon.

Fosi Audio Team"

As noted above that link is for pre-order.

When Fosi first announced the power filter delay I told them to hold my amps and wait to ship until everything was available; I got a shipping notice in the last week or two so assume at least the Kickstarter power filters are now available though.
