Meets or exceeds marketing statistics and has cool features! - Electronics engineer's review will be coming soon (tm) As a consumer, the A70 just works. It is a great amplifier with some really cool features I never knew I needed. As far as I can tell, it meets or exceeds all its specifications for TDP, power output etc. I will be evaluating this in more detail under different loads at a future date so for now I will cover more of the cool features: 1. XLR is a nice to have. I don't personally have any in my setup but occasionally I have used it for odd or specific setups. 2. The +6db is REALLY nice. Some audio sources are really quiet. The worst offender is an LG TV that automatically drops the volume every 30 minutes if you set it above a certain level in the UI. The trouble is, the TV doesn't actually know how loud the room is so this may be going from a comfortable volume to nearly silent. The +6db allows you to get the full range out if this amp with such sources. 3. The built in crossover is cool. Not used as I have a full equalizer for room calibration but I can think of times it would be useful. 4. The 12V trigger is awesome! I cannot wait to build a custom controller for this that allows it to be switched on and off with the rest of my setup to allow for energy savings. I really only have two gripes: 1. AIYIMA already has a product with the name "A70" which could be confusing. They also advertise this as being used for 7.1 surround setups, but having 8 of this seems like it would require excessive tinkering to get a room to sound good compared to an all-in-one receiver that is programmable. Review: Nice for the price - This amp does a pretty good job. The power supply it comes with is a quality item that delivers it's specified output, and can even supply more than 8.3A. I tested it on my electronic load, but my load is 400W max, which this supply delivered. That was a nice surprise. Chinese supplies I've bought on desertcart before usually provided only half their rated output current. Can the amp deliver its speced power? The ratings don't specify RMS, continuous power, so perhaps it can provide 600W for tiny peaks into 2Ω, but it can't output a sustained 600W. With a 2Ω load, the power supply goes into protection and shuts down at about 315W RMS. With my bench supply, it can deliver about 450W. It draws about 10.2A to do so. But most home subs are 4 or 8Ω, so those unspecified ratings are more useful for many of us. I can increase the output at either 4 or 8Ω until the output waveform begins to distort without the power supply shutting off. Max power at 4Ω is 256 Watts RMS and it begins to clip with 8Ω at 170W. It only draws about 5.5A at clipping, so there is plenty of extra power in the PSU for peaks beyond the RMS ratings. This amp has unusually low input sensitivity. I connected my signal generator to it with an unbalanced TS 1/4", and to fully drive the unit I had to send 8V peak to peak. The rca input has a +6dB gain switch that should almost always be turned on when using this input. ## Features - High-performance amplifier: using professional audio components combined with high-fidelity circuit design technology, it can provide clear and powerful audio output, suitable for music enthusiasts and home theater - Compact and exquisite design: beautifully designed appearance, the metal shell is precision processed, making the product surface delicate and glossy, calm feel, comfortable touch, durable; at the same time, compact design, space-saving, convenient to use in different environments - Multi-input interface compatibility: support a variety of audio inputs, including RCA and XLR inputs, while supporting 12V trigger inputs, one-key synchronization device operation, simple and efficient, can be matched to adapt to a variety of audio equipment - This A70 MONO audio component amplifier use TI's TPA3255 high-performance Class D power amplifier chip,It features an advanced integrated feedback design and proprietary high-speed gate driver error correction(PurePath Ultra-HD).Delivering excellent audio performance while realizing high power outputs;Total Output Power 600W Mono into 2Ω at 10%THD+N in PBTL Configuration,Total Output Power 480W Mono into 2Ω at 1%THD+N in PBTL Configuration - This A70 mono Home audio amplifier achieves unparalleled high performance due to the use of superior components, with low distortion of 0.001%, a signal-to-noise ratio of up to 116dB, and a frequency response of 20Hz-20KHz (±0.5dB) - Outstanding features of the A70 mono hi-fi speaker amplifier, specifically for the RCA input interface to increase the gain of 6dB, add active subwoofer output interface (40-200Hz optional) design, full-range output / passive subwoofer output dual-mode switching to meet your needs to achieve a variety of different scenarios such as mono / 2.0-channel / 5.1-channel / 7.1-channel use,Also it's a home subwoofer amplifier - Package included: 1PC A70 MONO class d monoblock amplifier ; 1 PC DC48V 5A GaN Power adapter; 1 PC User Manual(Note:Trigger input function is not compatible with wiim devices) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DFM7DNVN | | Best Sellers Rank | #109,803 in Electronics ( See Top 100 in Electronics ) #665 in Audio Component Amplifiers | | Brand | AIYIMA | | Built-In Media | 1 PC AIYIMA A70 MONO Amp, 1 PC DC48V 5A Power Adapter, 1 PC User Manual | | Customer Reviews | 4.1 out of 5 stars 84 Reviews | | Item Weight | 2 pounds | | Manufacturer | YIMA TECH | | Mfr Part Number | A70 MONO | | Model Number | B2D3232B | | Number of Items | 1 | ## Images ![A70 Mono Amplifier with PFFB TPA3255 Audio Receiver Class D Amp - Image 1](https://m.media-amazon.com/images/I/41RzChCpZoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent amplifier.

I wasn't able to run amps at full bore due to sound was too loud. No joke. Previously, I was using a Douk tube preamp which until it went out within 3 weeks of use. I thought sounded good until I decided to paired with the PX2 preamp, and they work really together. The Aiyima is clear and articulate as any full size amp I've had used before. I'm talking about NAD, Adcom, Hafler or Yamaha.And I had them cranked to just over 1/2 where the sound was too loud with no distortion or breakup. No Bluetooth with this amp. I was surprised at the headroom given, and the attack time was spot on. I'm not joking. But how long with these last, no idea. I got these new on sale, one for $118 and the other was $85. I highly recommend, will fill a room 18'x15' with no issues and volume to spare. So far a strong 4.5 amp! ## Frequently Bought Together - AIYIMA A70 Mono Amplifier with PFFB Home Audio Receiver,TPA3255 Class D Amp with Subwoofer for Home Theater Bookshelf Speaker,with XLR & RCA Inputs & Trigger Input - AIYIMA DC48V 10A GaN Power Supply Adapter for TPA3255 Stereo Class D Amplifier A07 & A07 MAX & A08 PRO & A70 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/655212336-a70-mono-amplifier-with-pffb-tpa3255-audio-receiver-class-d](https://www.desertcart.kr/products/655212336-a70-mono-amplifier-with-pffb-tpa3255-audio-receiver-class-d) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-04*
