A50 PRO HiFi Power Amplifier, High/Low pass filter 2.1-Channel, Infineon's MA12070P Chip, Bluetooth 5.0/USB/Optical/HDMI/AUX input Passive subwoofer with adjustable volume, with Remote Control

Skip the Arylic and buy this! Worked for me. HDMI arc, out of the box, plugged in, set Hisense TV audio output to arc and PCM or something, TV speakers off. Done. Only had it for a day but it works great sounds great. Running this to power 2 dayton audio b40s. Simple and small, sounds waaaaaaayy better than the TV speaks. Will add a sub later. The Arylic seemed nice but the HDMI arc did not work, the audio was at 100 and you could barely hear it.

Good little amp. Bought to drive my bookshelves and small sub for my tv. Works with arc perfectly, and has plenty of inputs. Booth works easily and the eq, tone controls, and low/high pass filters are helpful for tuning! Provides plenty of power to my 6 ohm speakers and is crystal clear. Can’t beleive how small it is! This is a win! Update - could not get my subwoofer to work as it’s not passive. Disappointing. Not sure why they chose to use speaker level inputs like that instead of just having an RCA sub out. Just be careful with what sub you use - mine doesn’t have high level output so this amp won’t work out after all.

This is a fun little Amp! I set it up for Dad as a soundbar replacement and to use with a Bluetooth turntable. We had tried a cheaper BT amp with a remote, but the volume control was spotty and he didn't like that. This one works fantastic, though. Setting up tone controls and navigating menus is a little clunky, but you don't have to do that often. It sounds really good! I haven't compared it to any of my higher end gear in an A-B comparison, but it holds its own with decent speakers. It has a multitude of digital inputs. Bluetooth connects quickly and easily. Remote works well. I like that it has a sub output with switchable and adjustable crossovers, both LPF and HPF so you can really dial it in. We're not utilizing it right now, but I'm tempted to buy one just so I can play with it and a passive sub! The display, although small, is enough to clue you in to what you're doing. It's better than a lot of this type of amp that have no display at all.

Very good amp. Has some nice features. Has a mild eq, bass, treble, subwoofer controls including high and low pass filters. The amp sounds very nice. Great features for the price. There are not many 2.1 amps with optical in this polished. Highly recommend for many systems. Currently using it with a small sub woofer and 4” main speakers and I am very much impressed with the sound and volume. How don’t think you could do better at twice the price.

I've owned this unit for 6mo and Its ok. Pretty good sound for the price, but a lot of minor issues. I am running into the problem where the device doesnt repond to power down, setting change, or respond when external input is applied. I need to frequently unplug the DC barrel jack to reset it and have not received a response from support team. Power button no longer works and need to restart everytime now to get sound to come out of the amp. Do not recommend this product.

I've been using the SMSL A50 Pro in my DIY soundbar build, and while there’s a lot to like, there’s also a major drawback that holds it back from being a full recommendation. The positives: HDMI ARC support is fantastic — it lets me control the amp and TV volume with a single remote. The customizable crossover settings are a great feature for integrating L/R speakers with a subwoofer. Sound quality on the L/R channels is clean, detailed, a bit harsh with my build but the EQ settings let me fix that. The Negatives: The subwoofer output is a major disappointment. Even with bass boost on and the subwoofer level maxed out, the A50 Pro struggles to deliver enough power. I designed my passive radiator subwoofer to reach full excursion at around 40W, but this amp can't get it there — even after upgrading to a 220W aftermarket power supply. For comparison, my Fosi BT30D (also rated at 100W sub output) easily drives the same sub to full performance, showing that the limitation is clearly in the SMSL’s subwoofer amp design, not my speaker setup. Given that one-third of the amp’s purpose (the subwoofer channel) doesn’t perform as advertised, I’m giving it 3 stars. It’s still a solid product for L/R duty with a powered subwoofer, but if you're planning to drive a passive subwoofer, you’ll likely be disappointed.

Great little amp! I’m using it to power some Jamo 803s! It also it’s prefect when hooked up to subwoofer

This very nice looking amp has a ton of great features, sounds very good, has a remote control, etc. but did not work for my system. The mono subwoofer speaker output is too low and could not be turned up enough to provide adequate bass to blend with my mids and highs. If the stereo full range output pre-gain could be adjusted down to better match with the subwoofer output, that would be helpful. Perhaps that feature could be added.
