Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, ave you considered / tried a converter cable similar to the product shown HERE?
Alternatively, if the old 3-pin DIN cable is still available, how about cutting 1 end and soldering in an RCA plug?
To my recollection, actually a left & right + ground.
Still, bear with us; re-confirm and post back with the complete model number of the Kenwood. If I can look over the schematic diagram (if available) then I could confirm or propose an alternate approach.
I checked the schematics/Service Manual of the Kenwood DVR-5070 and it would appear that the 3-pin DIN carries not only audio but switching trigger and a +V rail.
...not a simple DIN to RCA adapter but a circuit modification is needed.
Please post back how you would want to approach this and/or should additional information be needed.
It would require "fooling" the subwoofer to turn on. What is the model number of the subwoofer please?
