Review: オペアンプを換装したら大化けのアンプになった。 Review: 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. ## Features - High-quality components: AIYIMA A70 mono Mini Monoblock Class D Amp is equipped with Japanese rubycon 63v 3300uf filter capacitors, ELNA audio capacitors, German WIMA capacitors and professional high-power single-mode inductors, which reduces the distortion rate to 0.001%, the signal-to-noise ratio to 116dB, and ensures high-power output. - High-performance amplifier: A70 Mono is designed for HiFi enthusiasts, with rated power up to 300W @4Ω with 10% distortion. The A70 Mono is designed to add 6dB gain to the RCA input jacks and active subwoofer output jacks (40-200Hz selectable), with full-range output/passive subwoofer output dual-mode switching to meet your needs for 2.0/2.1/5.1/7.1 channels and other different scenarios - 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. Note: The 12V trigger must be connected to a preamplifier and must come with a 12V trigger output（not compatible with WiiM brand.） - 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 - PFFB circuit design: A70 Mono uses PFFB (post-filter feedback) technology to effectively overcome the common load dependence problem of Class D amplifiers, improve distortion, enhance frequency response, and thus greatly improve sound quality and performance. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DFM7DNVN | | Best Sellers Rank | 12,405 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 46 in Hi-Fi Amplifiers | | Box Contents | A70 Mono Amplifier*1 48V5A Power Supply*1 | | Brand Name | AIYIMA | | Country of Origin | China | | Customer Reviews | 4.3 4.3 out of 5 stars (82) | | Item Weight | 907 g | | Manufacturer | YIMA TECH | | Manufacturer Part Number | A70 MONO | | Model Number | B2D3232B | | Product Warranty | 24 months | ## Images ![– A70 Mono Power Amplifier with PFFB TPA3255 Mini Class D Amp with Subwoofer HiFi Home Theater Receiver with RCA/XLR/Trigger Input for Bookshelf Passive Speakers 48V/5A Power Supply - Image 1](https://m.media-amazon.com/images/I/41RzChCpZoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by 飯***子 on 4 March 2026* オペアンプを換装したら大化けのアンプになった。 ### ⭐⭐⭐⭐⭐ Review *by N***S on 10 October 2024* Electronics engineer's review will be coming soon (tm) As a consumer, the A70 just works.

Che dire,lo sto usando con l'impianto HT in mono su un subwoofer con 2 altoparlanti 4 ohm da 25 cm messi in parallelo tra loro. L'apparecchietto,per le dimensioni, se la cava egregiamente: pilota il subwoofer alla grande,senza minimamente riscaldare. Si, lo consiglio! ## 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.pl/products/657204428-a70-mono-power-amplifier-with-pffb-tpa3255-mini-class-d](https://www.desertcart.pl/products/657204428-a70-mono-power-amplifier-with-pffb-tpa3255-mini-class-d) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-11*
