How to: Choose the right banana plug?
- Closed Screw Type. All Fosi amplifiers use standard-sized speaker terminals (4mm pins).
- Easy to wire up and solidly connect to amplifier and passive speaker.
- If they do not fit, use a little force to tighten the plugs.
- Fosi Audio Banana Plugs (Copper, Silver/Gold Plated): http://bit.ly/40Djq0U, https://bit.ly/3MkPL8t
- Please watch tutorial videos: https://youtu.be/6pYhoqDlvNw / https://youtu.be/RGvBgGAwS9k
How to Diagnose Power Supply Failure?
- The following situations may cause this issue
- Case 1: The LED on the power supply does not light up; Case 2: Amp/Preamp does not turn on; Case 3: When plugged into the Amp, both light on the amp & power supply start blinking; Case 4: Amp/Preamp make noise; Case 5: Sound shuts off by itself
- Possible solution
- Check if the power supply is illuminated when plugged into AC by itself.
Plug power supply into a different socket.
Test the adapter with a meter.
Try a different power supply (within a range of DC input).
Test the included power supply on other electrical equipment.

What is a GaN?

- Offers overload and over-temperature protection.
- The 48V 5A GaN power supply is also available on Amazon.
Concerned I may have received standard 48 volt units since size is same (GaN described as smaller) and has the same part number.
And, no discernible sonic advantage.
Perfect for my set up with my Fosi BT20A Max amp.
Love the Fosi products

Fantastic Power Supply, using it with the Fosi Audio V3 - very happy.

I had trouble with a local distributor intentionally sending me a broken product, which I then had to return. I contact Fosi HQ, they courteously offered apologies, and explained that and how I could order direct with them and offered a discount even. The package arrived quickly and was properly packaged and sealed. Happy with the product and service.

I ordered this power supply with a ZA3 power anmolifier and a Fosi DC power filter. It’s compact and stays cool under load and well made with high quality cables.

I bought it twice on Amazon and both times received what seemed to be used products. I returned them both and ordered direct from Fosi and received a new one. I'm not sure it makes a difference in my system, but it stays nice and cool and is well built. If nothing else it should last longer than the standard power supplies and as a bonus you may save a few pennies a year.

Da oltre un anno tengo costantemente collegato alla rete questo alimentatore connesso al mio piccolo amplificatore BT20APRO che uso in cucina con due casse Kef. Devo dire che non mi ha mai deluso. E' stabile, silenzioso e non si surriscalda. Ritengo affidabile al 100%

I didn't notice the power lead change when I ordered the power supply, so now I have the older one with a figure 8 plug and the new one that has the earthing point.
They both work very well and the power supplied is balanced.

The power supply I ordered arrived in good condition and working order once I received it. Supply works exactly as advertised. This order got hung up in US Customs handoff to the Post Office and it appeared to be lost. However Fosi Customer Service got engaged and somehow spurred finding the package and getting it moving from Customs to the Post Office for delivery. Their help was greatly appreciated.

Got the Fosi Audio ZA3 with the 48V GAN Power Supply and the ZD3 to go with a Wiim Pro Plus, through GR Research crossover modded Neumi BS5s... and it all sounds exquisite! Quality components at real people prices!

Worked very well for my Aiyima A08 Pro driving 2 8" Cambridge Soundworks drivers in undersized enclosures I bought on Amazon and lined the walls with damping material and stuffed with cotton in an attempt to compensate for the enclosure being undersized. This power supply definitely gave them quite a bit more punch than the stock power supply. I first tried a Skuaike 48 volt power supply but was very disappointed with the noise they produced going through my speakers. I am also using these for two Aiyima AO7 Max's. There is still some noise through the speakers but not nearly as noticable as with the Skuaike power supply. I'm sure the noise is not helped by the wiring in the house I live which is over 100 years old.

Its is a good power supply that conforms to all standards.

It costs more than the TB10D and took a long time to get, but it's a game changer. Definitely worth it if you have high draw speakers.
