How to hook up teac model 2, mb20, to teac 3340

Hello new to the forum. Hope some one can help. I just recorded live music on my teac 3340 s. I used 4 mics to record a live band. I recorded on all four tracs. How do I play it back through my two channel system using the teac model 2 board with the mb 20 meter board attached( and the 3340 tape machine of corse) . I cannot seem to find the wire diagram. I need to squeeze all four tracs into my two channel. Thank u.
