Multiple input connectors are available for integration with a variety of devices, including a stacked set of ¼\" jacks for DJ mixers or keyboards, RCAs for CD players and a mini 3.5mm jack for smartphones and tablets. The J+4 delivers exceptional sonic performance, and is able to provide clean gain and eliminate noise by combining the advantages of active signal buffering with transformer isolation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJ+4 Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Using the J+4 to boost a stereo signal\u003c\/strong\u003e\u003cbr\u003eIncreasing the output from a CD player to a +4dB balanced signal is easy. Just plug into the RCA inputs, adjust the volume level and the J+4 does all the work.
