How to solve signal loss during PA transmission?

The background music (BGM) that is played in parks, scenic areas, shopping centres, playgrounds, and other locations is typically of poor quality and can be difficult to listen to; in some extreme weather situations, it even frequently makes noise. This is a widespread issue in the PA sector, along with poor sound quality, a slow response time, ineffective gearbox, and weather-related effects on long-distance gearbox. Therefore, instead of using the PA system in some locations with high sound requirements, consumers typically opt to buy foreign equipment, which not only raises the cost but also slows down after-sales maintenance and cannot offer a good warranty for use.

In truth, the industry has developed a number of practical solutions to the gearbox issues with PA systems. Here are a few workable options:

1. Create a digital signal from an audio source for transmission. The transfer of the audio source from the controller to the amplifier adopts network signals, which can lessen the loss of the audio source throughout the transmission and conversion process. The audio sources are stored as digital signals.
2. For short-distance transmission, use a speaker with constant resistance. Without an inter-wire transformer, the constant-resistance speaker does not perform secondary processing on the transmitted sound, significantly reducing sound loss and slightly enhancing sound quality.
3. Depending on the circumstances, choose various transmission lines. The lines get bigger as the situations get worse. We typically employ rvv2*1.5 lines in a typical interior context and rvv2*2.5 lines in an outdoor scenario to generally ensure the sound impact.
4. Pick a speaker with higher internal damping and superior materials. The last medium to produce sound is the speaker, which has a significant impact on the sound effects. improved speaker materials can result in higher sound reproduction and improved sound quality.

In order to address the present transmission issues with PA systems, the itc R&D team thoroughly investigated the broadcasting transmission signal, took lessons from earlier ways of improvement, and ultimately created the itc digital PA system. The digital PA system begins with the numerous media in the sound transmission process, optimises, and enhances each connection to produce the sound effects of high fidelity, low latency, and lossless transmission. It does this by using professional noise reduction algorithms and audio processing technologies.

HIFI Sound Quality
It is simple to resolve the issue of audio source loss during transmission using 48k lossless acquisition and lossless format transmission. Utilising a professional digital amplifier, an integrated network decoding module, high and low filtering, a limiter, and a built-in DSP audio processor, it is possible to realise network BGM playback and significantly lessen sound loss during the audio decoding process. High-fidelity speakers guarantee better sound reproduction.

Low-delay Transmission
A 1/1,000-second end-to-end digital optical communication is possible. Additionally, there is a 1/100,000 second transmission delay on the ultra-low network. It allows for the simultaneous playback of music in several zones and the dissemination of emergency information. The emergency response is quick, and the interval of meaningless synchronisation is nearly zero.

Lossless Transmission
It can significantly reduce the impact of hard conditions by using optical ultra-long-distance transmission, high bandwidth, and anti-electromagnetic interference. It can deliver superior audio processing, lossless audio conversion, and a better original sound effect when connected to a professional DSP network amplifier.

A complete management system that is extensively utilised in the cultural tourism and professional sound industries is the itc digital PA system. The system includes a number of functional modules, including high-fidelity broadcasting, real-scene monitoring, mega data statistics, information push, multi-track broadcasting, senseless synchronisation, float parade, emergency assistance, etc. It has created a full and excellent audio solution using audio source capture, audio transmission technologies, professional digital amplifiers, and HIFI speakers.
