Thank you for purchasing A5/A7/A7 mono series amplier which has latest opmized post lter feedback
design, we hope it could bring you more fun to enjoying music!
It is recommended you read this manual rst before you starng to use all features of this amplier.
The A5/A7/A7 mono series amplier are the rst-generaon nished amplier we make that integrated
with mul-funcon that based on user needs like op-amp changeable and auto audio sensing technology
which bring more exibles for various use cases. The A5/A7/A7 mono series amplier 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 o automave to reduce power lose for green energy saving
and also thermal dissipaon, user can easier to use with other DAC source to reduce the complex operaon
of the whole audio system.
Our engineering team put many eorts on opmizing the post lter feedback design based on Ti’s
recommendaon and achieved a very great performance with 0.0003% THD+N(A-wt) at a typical 5W
output, this is the best data based on TPA325x design in the world (as of Oct-2024), in the meanwhile,
frequency response also had been extended to 35KHz within 0.5dB deviaon.
For some user that used to use their DAC source to fully control the volume, there is an opon that we add
into this product is volume bypass mode, which disable protenonal meter in audio path to fully ensure a
pure audio signal chain from the DAC source to the amplier output ll speaker end, achieving the ulmate
sound quality experience.
Furthermore, this product support op-amp change to maximum user’s diy hobby as they experienced that
dierent op-amp bring them dierent sound percepon, an easier way without opens the chassis is
implemented in our design to save user’s operaon process and also reduce the risk of disassembly, see
operaon secon for detail.
Finally, enhanced design, exceed the edge, enjoy sound with passion are always our mission and we
sincerely hope you enjoy our products.
