Correction to model number, it is an AP 2000. A simple circuit that gives the least interference to the signal. This was my foundation in the two channel system, with excellent phono (MC/MM) and line level clarity. NO buzzes or hums. Has normal full range output or 2.1 capacity with a built in 12 dB/octave crossover at 75 or 150 hz for the sub, and 150 for the satellite. Remote works fine, activates the volume and the input selector, does not operate the record out selector, so this must be manually selected. Cosmetics are about 7, has a normal age appearances with a used item. Free shipping. Call 402 498 2773 or email, do not text.
