hey I just got a used "bbe 362nr sonic maximizer" And I do not have a manual so I am wondering if someone could help me out. first of all it has four 1/4" jacks on the back. output A,B Input A,B. My guess is one channel is for the noise reduction channel and the other for the processing. However how the heck do I hook both channels at the same time? where do I plug them etc... I use a swr bass 350. any help is greatly appreciated.
