The ASPC1 Audio System Polarity Checker is an essential tool for system technicians, designed to ensure that all drivers in a sound system are operating with correct polarity.
It consists of two components:
1. Pulse Generator: Emits a positive phase signal and features a flashing yellow LED to indicate the pulse tempo and signal that the device is active.
2. Detector: Uses green and red LEDs to display whether a driver has positive or negative polarity, and includes a flashing yellow LED to confirm that it is operational.
