Transient voltages from powering up source equipment can damage speakers if amplifiers are already turned on. Ensure amplifier volumes are set to their minimum settings and power up any system amplifiers LAST. Allow all system components to stabilize for several seconds before introducing any source signals or making level setting adjustments. Similarly, when shutting systems down, turn all amplifiers off first, before powering down any other system components.
5. CABLES - Do not use shielded or microphone cables for connection between amplifiers and speakers. Use only approved speaker cables with proper connectors.
