The move from MKI to MKII was more than a cosmetic revision. It reduced hardware bulk, modernized power and connectors, and helped turn the ZC95 into a more cohesive four-channel platform.
The original ZC95 project was published in late 2021 according to its project repository. From the beginning, the design was notable for four isolated channels rather than the two-output layout common to classic 312-style boxes.
The first generation used a separate output-stage board, 2.5 mm output connectors and a 12 V sealed lead-acid battery. The architecture worked, but it required more internal volume.
For MKII, the main board, audio section and output-stage functions were consolidated. The project documentation describes the new main board as less than half the size of the earlier arrangement.
The older 15 V barrel-power approach was replaced by USB-C, while a 26650 cell replaced the earlier SLA battery. Output connectors changed from 2.5 mm to 3.5 mm.
Bluetooth, Wi-Fi, remote control features and Lua scripting now make software behavior a major part of what differentiates the ZC95 platform from simpler two-channel devices.
