Hooking up speakers to the Fosi Audio BT20A is pretty straightforward. Let's walk through it together, step by step. I've also got some insights from our research that might help.
Physical Connections
First off, make sure the amplifier is turned off to avoid any mishaps. The BT20A is meant to work with passive speakers, so grab some speaker wires and connect them to the amp’s output terminals.
Pay attention to the polarity here—match the reds (positive) and blacks (negative) on both the amp and your speakers. Once things are hooked up snugly, go ahead and plug the amplifier into a power source.
Bluetooth Connectivity
The BT20A supports Bluetooth, which is pretty handy. It uses Bluetooth 5.0, so you'll get a strong connection up to about 50 feet away—our research backs this up.
To connect, power on the amp, enable Bluetooth on your device (like your phone or tablet), and look for "BT20A" in the Bluetooth settings to pair.
One thing to note: while the Bluetooth feature is cool, some who have used it have mentioned that the amp stays in pairing mode when not actively connected. That means nearby devices could accidentally hook up if you're using the RCA inputs, which might interrupt your tunes.
Potential Solutions
The BT20A doesn’t come with a switch to turn off Bluetooth, but there are workarounds. A few people suggested using a separate Bluetooth receiver that you can turn off when you don't need it.
Another option is to keep tight control over which devices can connect to your Bluetooth, lessening the chance of random pairings.
Connecting speakers to the Fosi Audio BT20A amplifier is pretty simple, whether you're using Bluetooth or RCA inputs. Just keep an eye on the Bluetooth quirks, and you should have a smooth listening experience.
Enjoy the sound!
