I know these things are not in use much these days so I am not not sure how to connect/what to connect. I picked this up at a thrift store and do not have the manual. The model is a TEAC EQA-5 if that helps. It has a line in connection (left and right) and output and under tape it has a play connection and mic connection. I am looking to hook it up to a Kenwood VR-307 for now. Thanks in advance for any help.
