Description
rocess standards: With the consistent mechanized AI and SMD
processes, more discrete components, and durable design, we are
your loyal business partner! The material adopts a lower leakage
magnetic ring transformer and customizes a high ripple current
audio professional capacitor, with the aim of improving sound
quality and product stability.
Market positioning: Specially designed for mass sales KTV or
multimedia engineering. Low static noise: The input noise of the
front stage is turned off in microseconds, and there is no static
noise interference. Smooth music, quiet and comfortable indoor use.
Good sound quality: Deep and thick low-frequency, sweet and loud
mid-range, and slender high pitched. Easy karaoke, durable and
beautiful room entertainment.
High efficiency: The whole machine outputs efficiently, operates at
low temperatures, saves energy and electricity, and is low-carbon
and environmentally friendly.
Soft protection: working with short circuits, low resistance, and
overheating, continuously outputting, and indulging in
entertainment. Stable performance and reliable operation.
Small size: 2U body, short depth, easy to place inside the cabinet,
saving storage space.
