🔊 High-Quality Bluetooth 5.0 Power Amplifier 2 Channel Stereo Mini Hi-Fi Integrated Amp 2.0 - 50W x 2 USB Wireless Audio Receiver for Home Speakers & Headphones - Douk Audio Tone (Silver) Review

PSU is rubbish. DO NOT USE! The cap says "LITE-ON Model: EADP-75GB A". The plastic case could not be closed due to the PCB design. See Figure 1. Very thin PRIMARY wires, barely connected (and partially exposed)! See Figure 2. The extra secondary wires are cut off and simply left hanging in the case. See Figure 3. The non-working power LED is only connected with a (bare) wire and hangs in the housing. See picture 4. The worst thing is that the separation of primary and secondary is completely…

I needed an amplifier that would accept Bluetooth inputs from my Alexa and transmit sound (for music) to my 7 or more classic bookshelf speakers. Yes, that says 100 watts (50 page) but not with the power turned on. Another problem I can't solve is that when pairing with my Alexa, if I turn off the amp by turning it back on, Bluetooth doesn't automatically reconnect to Alexa. Usually you just say Alexa, Para. and the device will automatically pair with what it finds in the band it was previously

Pros: * Item comes in a sturdy box - thick foam padding matches the amp and power supply * 4 input source selection with volume control as a selector * Solid rubber feet on the bottom help keep the amp in place * Bluetooth range in a room with obstacles over 50 feet * Power button allows you to switch to standby mode without turning off the unit completely * LED indicator Front panel displays input source input signal and visual volume level for each channel * Seller actually responds to most…

The only problem: he likes to switch off. If this amplifier loses the Bluetooth connection within 30 minutes, it will turn itself off. You need to press and hold the power button for 2 seconds to wake it up before pairing again. That means you can't hide it in a closet or anywhere else. It should be outside where you can press the power button before each use. The vendor says this feature "saves power," but it's fake. I'm an electrical engineer making things harder, and I can tell you that any…

The Nobsound Tone has an attractive design, convenient location and connectivity. Despite its small size, it offers USB, a 3.5mm input jack, a headphone output (also 3.5mm) on the front, and speaker mounting ports on the back. RCA line input and power supply (included) are connected on the back. Tone also offers Bluetooth connectivity. Volume and input selection are combined in a large circular bar on the top of the device. The device's appearance is rounded off by a highly polished front…

I've had it for a few weeks now and it drives a pair of 35w 8 ohm Monoprice bookshelf speakers fairly well. I use it in the office in combination with the echo dot and everything goes very well. What I like: - Sturdy construction. This item is not cheap. - Great sound, crystal clear, warm "tube" clips. Seriously, this thing sounds great. - Bluetooth is easy to use and works very well - I use unbalanced line for echo dot and BT for my Mac or phone, it's perfect for office work. - All power…
