Product Name: Digital Singular Wire PA System (SWPA-01)
Description:
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.
