PLA supports the "Music of Kucha" 2025 Pipa Ancient Music Festival

When the echoes of history meet the modern stage, the strings of the pipa will take us through thousands of years. The grand opening of the 2025 Pipa Ancient Music Festival is not only a musical carnival, but also a cultural origin and inheritance.

This grand ceremony brings together top pipa performers and traditional Chinese music artists from both domestic and international sources. Led by Professor Fang Jinlong, we collaborated seamlessly with Xinjiang percussionists and international artists to deliver breathtaking performances. They use their agile fingertips to dance on the strings, letting the ancient pipa tell the story of time. The golden and iron horses of "Ambush from Ten Sides" and the gentle and tender feelings of "Spring River Flower Moon Night" were presented one by one in this grand ceremony.

Here, the audience seems to be immersed in the bustling market of the ancient Silk Road, or strolling through the elegant music scene of the Tang and Song dynasties, experiencing the unique charm of pipa ancient music.

PLA PS4P active speaker:

This is a very compact active speaker with a built-in power amplifier that can be directly connected to a microphone and other audio signal sources. This type of speaker provides clear sound on-site, allowing the audience to better enjoy the music. Adopting a metal aluminum shell, the overall appearance is small and exquisite; Built in amplifier circuit, active output, self-contained; Use one high-efficiency 4.5-inch full band unit; Equipped with D · AMP (Class D Amplifier) digital amplifier circuit technology; Equipped with MLC (Microphone&Line Combined Input) preamplifier circuit technology; Having FCT (Full Frequency Coherent Technology) full frequency coherent technology;

 

 

 

PLA MS01Pro, MS08Pro, MS16Pro Passive Microphone Distributor:

This device is used to mix multiple microphone signals into one signal for easy transmission and amplification. This can make it easier for on-site sound engineers to control and adjust various microphones on stage. Specially designed for mobile 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 microphone; Provide phantom power for work

 

PLA DI200 Pro active isolator:

This device is used to isolate microphones 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;

 

 


PLA ISO2 PRO Dual Channel Line Isolator:

Equipped with AIT (Audio Isolation Technology) audio isolation technology; Integrated aluminum alloy body, providing good shielding; Built in isolation transformer to eliminate noise caused by grounding circuit arcing; Completely passive use, no external power supply or battery required;

 

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.
