This device is used to mix multiple microphones signals into one signal for easy transmission and amplification. This can make it easier for on-site sound engineers to control and adjust various microphoness on stage. Specially designed for mobiles performances; Broadcast grade audio isolation transformer output; Highly integrated, sturdy and durable all metal body; Manufacturing of military indicator accessories; Independent ground separation setting selection; The working level can reach+26dBu; Featuring patented PPD phantom power supply technology, each output can simultaneously serve as a condenser microphones; Provide phantom power for work;

PLA DI200 Pro active isolator:

This device is used to isolate microphoness and other audio equipment to prevent grounding loops and noise issues. This can ensure the transmission quality of on-site audio signals and avoid unnecessary noise and buzzing. Having AIT audio signal isolation patented technology; Imported VIGORTRONIX audio isolator; 2 channels, 2-in-1/1-split 2; +5USB interface power supply; Conversion between equilibrium and non-equilibrium; Input signal level indication; Output Mute mute function; Dual 6.35, RCA and Canon seats for entry and exit; Equipped with both common and non common ground switches;

TWINS primary and backup audio broadcast controller:

TWINS dual backup audio broadcast controller is designed for a secure audio system that can flexibly hot backup and control the input signal of the playback audio source. We use customized two independent Tpye-C interfaces and a fully standard XLR XLR XLR gold-plated socket to ensure a secure connection and stable data transmission. Equipped with two completely independent latest professional DAC chips, it supports ordinary lossless audio output PCM encoded 32Bit/384KHz and DSD encoded audio, which can truly restore lossless sound quality. Capable of hardcore decoding, able to decode DSD format and present rich details. By optimizing circuit design and shielding technology to reduce background noise and ensure pure sound. Support connecting two computers simultaneously to play both primary and backup audio sources simultaneously. When playing two sets of audio sources synchronously during a performance, two computers can be connected to TWINS to achieve simultaneous playback of one main and one backup. This is the most secure way to play during the performance, and even if one of the playback computers malfunctions, it will not cause music to stop in the event of a performance accident, ensuring that the performance proceeds normally. It is easy to use and does not require drivers. Any control software that supports MIDI protocol can be used.

PLA ES08Pro Primary and Backup System Switcher:
The ES series main and backup system switch is designed to arrange work for audio systems that can flexibly switch input signals between the main and backup systems. Adopting a fully standard XLR connector design and patented TT0 (Two To 0ne) seamless switching technology, it can connect digital or analog audio signals, allowing users to select signal sources according to their needs through switches, providing high audio specifications, and processing audio level signals. The main audio signal and backup audio signal are kept powered on, and the audio signal can be quickly switched through the switch on the front panel. It has RASDT (Real time Audio Signal Display Technology) real-time audio signal display technology, and two sets of 8-channel signal display screens display level signals in real time, making it convenient for users to observe the input audio signal.
