Product Name: Digital Singular Wire PA System (SWPA-02)

Description:
1. Do you believe SWPA only one wire series connect speakers more than 100 thousand?
2. Have you ever seen the broadcasting system does not need power amplifier?
Broadcasting system is very common in the daily life; however, the traditional technique is quite complicated and difficult in large-area broadcasting. For example, a giant-powered main amplifier is required and costs are very high; impedance matching is essential to speaker connection; loss power with long distance wiring; also need to be concerned of; the intricate speaker connections operate in parallel might increase a high cost; high voltage transformer causes the system distortion and bad frequency responses. due to main amplifier power is fixed;The traditional PA system limit to increase quantity of speaker after whole system installated; But our SWPA system can do it.

Problems in traditional broadcasting system:
1. High power amplifiers needed to drive the system.
2. High cost for system and setup.
3. Losses in wire will affect power delivered to speakers at a distance.
4. Multiple wires are required for connection causing setup to be a complex task.
5. Output power of speakers differs with respect to distance.
6. Imperfection in high voltage transformers results in lower sound quality.
7. Difficult to add more speakers to the system due to limited power from central amplifier.

Advantages of SWPA compared to traditional approach:
1. Small central controller for whole system.
2. Simple solution to setup of system (1 wire per system).
3. High voltage transformer not used (higher sound quality).
4. Longer lifespan.
5. Lower maintenance cost.
