The J48 Stereo uses a unique switching power supply that raises the internal rail voltage so it can handle up to an incredible 9 Volts, resulting in improved signal handling and greater headroom. This additional headroom significantly reduces distortion of all types, allowing the natural tone and character of the instrument to shine through. The J48 maintains stereo separation between the left and right channels, allowing it to be used on two separate instruments or with stereo sources such as keyboards.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eJ48 Stereo Applications\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUsing the J48 Stereo with a keyboard\u003c\/strong\u003e\u003cbr\u003eThe J48's active circuit and amazing signal handling makes it a great choice for both digital and old school analog keyboards.
