1. Do you believe our SWPA needs only one wire to connect more than 100,000 speakers in series ? 2. Have you ever seen a broadcasting system that does not need power amplifier? Broadcasting systems are very common in our daily life, but the traditional technique is either too complicated or cost ineffective for large-area broadcasting. For example, a giant-powered main amplifier is required and costs are very high; impedance matching is essential for correct speaker connection; power loss due to long distance wiring ; too much wiring for speakers connected in parallel which will increase the cost; high voltage transformer causes sound distortion and bad frequency responses. Futher more, power of the main amplifier is fixed, expanding the number of speakers can be a complex job. Our SWPA system can overcome all these problems,contact us today!
