Special Features
The A7 amplifier are the first-generation finished amplifier we make that integrated with multi-function that based on user needs like op-amp changeable and auto audio sensing technology which bring more flexibles for various use cases. The A7 amplifier are also use high quality capacitors, inductors and also implemented high quality PCB design to ensure its highest performance.
By including auto audio sensing power on and off automativeto reduce power lose for green energy saving and also thermal dissipation, user can easier to use with other DAC source to reduce the complex operation of the whole audio system.
Our engineering team put many efforts on optimizing the post filter feedback design based on Ti 's recommendation and achieved a very great performance with 0.0003% THD+N(A-wt) at atypical 5W output, this is the best data basedonTPA3255 design in the world (as of Oct-2024), in the meanwhile, frequency response also had been extended to 35KHz within 0.5dB deviation.
For some user that used to use their DAC source to fully control the volume, there is an option that we add into this product is volume bypass mode, which disable protentional meter in audio path to fully ensure a pure audio signal chain from the DAC source to the amplifier output till speaker end, achieving the ultimate sound quality experience.
Furthermore, this product support op-amp change to maximum user 's diy hobby as they experienced that different op-amp bring them different sound perception, an easier way without opens the chassis is implemented in our design to save user 's operation process and also reduce the risk of disassembly.
