Optimus SV-200MA is a surveillance board designed to be built into VWM-2120/-2240 amplifiers. It allows users to monitor individual speaker line or power amplifier failures, providing status indication. The board features a 24V DC power source, 120mA current consumption, and various inputs and outputs for control and monitoring purposes. It can detect power amplifier failures through 20 kHz pilot tone detection and speaker line failures using 40 Hz impedance detection with a minimum detectable load of 5W.
