Review: Decent receiver for $20 - I like this, has all functions + remote and using old school wired speakers. Goes loud enough with both volume knob and remote volume. For what you pay for, very much worth it. While not perfect, I observed the following: no headphone plug/jack, USB did not have random/shuffle and most importantly, when you power on with switch, the volume defaults to 30 (loud) be careful. Also, no memory save for settings except for USB.
Review: Functionality - Works very well with my Elimavi 30W*2 speakers! Blue tooth connects great.

## Questions & Answers

**Q: What is the reason for noise such as current when the amplifier is connected correctly?**
A: Please check that there is no current sound at no load and make sure that the surrounding current signals are not causing interference. Please make sure that all cables are fully pushed into the device, as incomplete connections can cause distortion.

**Q: Can the Bluetooth function and the wired connection be used at the same time?**
A: Please note that the Bluetooth function and the wired function cannot be used at the same time. When you want to use the amplifier via the Bluetooth function, do not connect any devices to the jacks (except the microphone jack).

**Q: Can you connect two devices with bluetooth?**
A: No, connecting two devices at the same time will cause the audio stream to be interrupted. You can only disconnect and then connect to another device.

**Q: When the Bluetooth connection is unstable, try the following steps to fix it.**
A: 1. Make sure there are no obstacles (especially metal) blocking the signal. 2. Switch off the amplifier, disconnect and clear the connection of the Bluetooth transmission device, and then try to reconnect.

**Q: Why does only one channel work?**
A: The amplifier is not intended to be used alone, it needs to be used with other electronic equipment, so it needs to be troubleshot on a case-by-case basis! Make sure that the positive and negative wires connecting the speakers are connected together!

### ⭐⭐⭐⭐ Exactly what I needed
*by D***S on August 17, 2025*

This is so cool! I love the idea of a mini stereo amplifier. It's just right for a small bedroom where surround sound and multiple inputs are not necessary, and it's very affordable. For my use case I have a Sony Bravia tv with no headphone output. I could connect my 12" soundbar to the audio output with a RCA to 3.5mm adapter, but the tv's volume buttons don't control it. This amp, along with a bare wire to 3.5mm adapter, solves the problem and the remote control allows to control volume from across the room. It took a few minutes of adjusting the volume levels of the amp and mini soundbar to prevent static but I got it worked out and it sounds very good. The FM tuner is nice and I don't expect to use bluetooth or usb inputs. I find the volume knob sort of sets a maximum desired level and then the remote control buttons adjust the volume within that level. Update: Knocking off a star because each day, after being off overnight, it had static again without changing any wires or volume levels. After a few days it became impossible to eliminate the static and even started losing sound from either left or right. I'm not sure if it's a side-effect of the 3.5mm adapter or if it's something internal.
