happymusic HD Audio PA-2 Adopt the imported audio transformer manufacturer’s custom pomero alloy material audio coupling transformer, the original imported Swiss NEUTRIK connector, sink gold circuit design, so that the signal perfect docking. Dual 6.35 and XLR card are in and out, which can be converted and distributed to each other. Each circuit is equipped with co-ground and non-co-ground switches, and group A, group B, co-ground and ground switch. It can completely isolate the potential difference between the two systems, avoid the ac noise caused by the grounding problem, and prevent the damage of equipment input components caused by the high potential difference. Realize the security transmission of audio signal. Remove noise from cameras, simultaneous interpreters,laptops, electronic instruments that connect sound, and devices that do not match the impedance of the device. It is also suitable for large-scale outdoor performances, lightning protection, sound engineering, multimedia conferences, entertainment venues, exhibitions, ect; it is a necessary equipment for audio system cascade.
