“My amplifier shuts off once in a while, usually at higher volumes.” Check y our voltage source and grounding point. The power supply of the XD700/5 will operate with charging system voltages down to 10V. Shutdown problems at higher volume levels can occur when the charging system voltage (or remote turn- on voltage) momentarily drops below 10V. These dips can be of very short duration making them extremely difficult to detect with a common DC voltmeter. To ensure proper voltage, inspect
