My subjective impression is, that there's something up with the treble. This is a review and detailed measurements of the AIYIMA A07 Pro stereo amplifier. While it may be flat with simple resistive loads (like the ones Amir uses), a reactive load like a speaker can lead to a different response. Of course, it costs double the plastic one used in the review. It embeds a TPA3255 amplifier chip capable of developing a large power of 2x225W under 4Ω, with high efficiency. 2 Bluetooth support: 16-24bit 44. Location.

There seems to be a very faint lack of higher frequencies (>7 kHz). CD player, streamers etc. 0. Unique and amazing combination: integrated A8 Pro amplifier with VU meter into whole in such a mini size, when enjoy HiFi music, the pointer dancing in the warm light with strong vintage feelings, dynamically decorates the audio system space. ASR member pma measured the A07's frequency response into reactive loads in this thread. Aiyima A07 Pro https://amzn. As can be seen the slew rate and bandwidth for any of the two op amps by far exceeds the spec required for 20KHz. With almost any speaker, as a complex load, they exhibit rise at the top end of audio band and thus they sound britle in a level matched A/B test with a good amplifier with flat FR into speaker load. Customer Reviews. Aiyima D05 Chips set: CM6642, TAS5508, TAS5352A, QCC3008, CS8422, WM8782. Featuresï¼1. There's really nothing special about it and nothing to complain about. Tried to make a "reverse engineering" from the posted photos of AIYIMA A07. According to Amir, dynamic range of TPA3255 amp is limited to 14. 8Vrms (19dB)RCA The Aiyima A07 is a small, simple, powerful, efficient and affordable Class D amplifier, ideal for setting up an audio system that requires a lot of power input. Feb 13, 2016 · 246,114. Please check before you write an info like this. supports LL and LDAC etc. For the money I buy now Behringer A800's. Dec 7, 2019 · This Class D Aiyima A07 MAX amplifier features a stereo and mono mode for daisy-chaining multiple A07 amplifiers for more power. Using TI's ultra-high-definition digital power amplifier ic (TPA3255), the output power is up to 280w*22. I am testing the A07 with 2 different power supplies. Aug 31, 2023 · Another one to add to Aiyima’s list of: “let’s add another variant around this same TPA3255 amp. Aiyima's recommendation of a 48VDC 7. They sound great, but 2 died, most probably they can't take 48V. It will be compared to other speaker amplifiers from the price range, including AIYIMA A07 PRO (89 USD), Fosi Audio BT30D PRO (109 USD), and Arylic A50+ (200 USD). I agree completely, Duncan that it seems strange the manufacturer would, theoretically, ship this with a 32V rather than a 48V power supply but as demonstrated in Amir’s review, the amp works infinitely better with a 32V supply than none!
