This AV selector can be fully utilized as a line selector and recording selector even with the original audio system. It can be used in the same way as Luxman or Orb, and is convenient for cassette enthusiasts because it has a recording selector. Please take a look at the back of the product. Looking at the select switch on the front, I think audio enthusiasts will be satisfied with the completeness of this product. ◯ Product Overview Panasonic AV Selector RP-AV600 Discontinued Product Equipped with S-terminals for 2 inputs and 2 outputs (including 1 monitor).
