CTs Multi-Channel Power Amplifiers CTs Multi-Channel Power Amplifiers 3 Operation (continued) 3 Operation 3.2 CobraNet and Control Module Features 3.1 Precautions Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety: 1. Before use, your amplifier first must be configured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties.
CTs Multi-Channel Power Amplifiers 3 Operation (continued) 2. Hold the Reset/Preset switch in for two flashes of the Data light (longer than 2 seconds). 3. The Data indicator will flash rapidly for a moment. 4. Restore the audio input signals. To restore the unit including presets to factory default settings: 1. Remove all audio input signals. 2. Hold the Reset/Preset switch while applying power to the unit. 3. The Data and Preset indicator will both light. 4.
CTs Multi-Channel Power Amplifiers 3 Operation (continued) Most amplifier/load systems can be configured and supervised by following these steps: 1. Configure your audio system using a known “good” load, then enable the Load Supervision feature. 2. Provide typical program material at a level high enough to light the “test” indicator. 3. Run the system at this level until the average impedance stabilizes. This may take seconds to minutes depending on level, duty-cycle, etc. 4.
CTs Multi-Channel Power Amplifiers 4 Advanced Features 3 Operation (continued) 3.3.3 CobraNet Output Routing CobraNet output routing includes the following controls: CobraNet Transmit Bundles The amplifier can transmit up to four unique CobraNet Bundles (TxA, TxB, TxC, TxD).
