 * GAODIMIC ®  Products of the same brand and model are consistent with this product.。


Characteristic


-Comprehensive hardware upgrade, significantly improved performance, and the addition of side switches for selecting input signals.

-Upgrade and shield high-precision variable pressure equipment, greatly improving frequency response characteristics.


Function


  1. Eliminate potential differences caused by unequal induced potentials in audio equipment with different phase lines and grounding points.

  2. Convert unbalanced signals into balanced signals transmitted on differential Canon lines. (The former has a transmission distance of less than 20 meters, and the distance in places with severe electronic interference is shorter; the latter can reach a transmission distance of over 100 meters.

Application Scenarios


Isolation between KTV industry equipment

Specially designed for TKV scenarios, there are differences in grounding resistance between equipment at different points, resulting in ground potential voltage differences between equipment and causing audio noise; There may also be an impact sound when the signal cable is unplugged or unplugged from the device, which may cause the interface chip of the device to be destroyed and the device to be damaged in severe cases.
