Thus, the amplifier will also be turned on. When the source unit is turn off the amplifier is also turned off. Using this feature eliminates the need to use the REM (turn on wire). The AUTO TURN-ON function will work with 90% of all source units because they are equipped with \"high power\" output. Only a few holder head units will not use this function.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional Features\u003c\/strong\u003e\u003cbr\u003e300KHZ HIGH SPEED PULSING: The switching speed of the Class D chip puts the amplifier sampling frequencies at over 100 times higher than human ears can hear.
