product description
Fully balanced post-level PCB is officially on sale!
At the request of many friends, we developed the M12 fully balanced post-stage on the basis of M9. For many years, we have no new products related to the post-level. M12 can be said to be a top-grade product with a lot of sound. Chinese people change the domestic power amplifier!
The M12 is modular in design, with the current amplifier stage and voltage amplifier stage separated and powered independently, making future upgrades easier.
M12 PCB (6 in total)
Supply voltage: voltage amplification stage: AC59V, current amplification stage: AC41V
Related parameters:
M12 current amplifier board size: 410mm long × 120mm wide

M12 voltage amplifier board size: 320mm length × 60mm width
Actual output power: 500W × 2
Note: The spot empty board is a yellow bottom plate!

The actual shipment is an empty board. You need to purchase additional parts yourself to install. All you buy is an empty printed circuit board, you must pay attention!






As different computer display the colors differently,and the color maybe is little difference from the actual items,but we can guarantee the style is same,but maybe some not same performance on different bodies as on the models.Hope you can understand it.thank you
