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\u003eFull Range Digital\u003c\/strong\u003e\u003cbr\u003eMono amplifiers focus on only subwoofer frequencies with Super D Class®, high efficiency\/high power technology to deliver maximum wattage.
