Still curious about the Fosi Audio BT20A Amplifier? Here are some answers you might find interesting:

🔊
What is the power output of the Fosi Audio BT20A amplifier?
The Fosi Audio BT20A amplifier isn't like your typical stereo [receiver](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dreceiver%26tag%3Dssw.ans.tx-1-20) because it doesn't have a built-in [tuner](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dtuner%26tag%3Dssw.ans.tx-1-20). This can be a bit confusing since it's sometimes advertised alongside receivers. Our research shows that some folks might be surprised by this, especially if they were expecting to access radio stations directly, which standard stereo receivers usually offer. When it comes to power output, this amplifier is pretty impressive. The manufacturer claims it can pump out up to 100 watts per channel at 4 ohms. That's a good amount of power for clear, detailed sound, especially if you're looking to enhance your sound system in a small to medium-sized room with passive speakers. The BT20A focuses on solid Bluetooth 5.0 connectivity, letting you stream music wirelessly from devices like smartphones, tablets, and computers. Plus, if you prefer a wired setup, it has RCA inputs too, giving you some flexibility depending on your preference. Just a head's up, if you're after an all-in-one device that handles both amplification and radio, the BT20A isn't going to cut it. It's specifically an amplifier, great for boosting sound to speakers, but not for tuning into radio stations. If you want radio features, you might need to check out products listed as receivers or think about adding a separate tuner to your setup. In short, if you need a dedicated amplifier with decent power and Bluetooth capability, the Fosi Audio BT20A is a solid choice. Just keep in mind that it won't replace a full-on receiver if you're looking for built-in radio features.

How do you connect speakers to the Fosi Audio BT20A?
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!
🔊
Does the Fosi Audio BT20A have a remote control?
The Fosi Audio BT20A Amplifier doesn't come with a remote control, which might be a bit of a letdown if you're hoping to tweak settings from a distance. According to our research, some folks have mentioned that this could be improved, especially if the amp isn't in an easy-to-reach spot. The manufacturer describes the BT20A as a compact and powerful amplifier that's great for home, outdoor, or garage setups. But yeah, without a remote, it might be less convenient if you like having control at your fingertips. If having a remote is a dealbreaker for you, maybe check out other models that include this feature. Just keep in mind that adding a remote might mean compromising on other things like size or cost. Fosi Audio has other amplifiers, or you could look at different brands on sites like Amazon to find one that fits what you're looking for. So, if you're cool with adjusting things manually, the BT20A could work well. But if a remote is really important for your setup, it might be worth searching for a model that includes one.
