Question about Technics SA-AX720 Receiver
I picked up a SA AX720 to hook up with the TV in my office at home but I can't get the subwoofer working.
I have a 42 flat screen an HDMI DVD player with a Captive Works Satellite plus a cable signal.
I also bought a set of Sony SA FT3H speakers for a very good price used, still in the box and thought I was doing pretty good. This six speaker system has a powered subwoofer.
When the Technics didn't seem to work, I pulled my Pioneer VSX-D711 from the basement system and hooked it up just fine and the subwoofer works great.
I put it all back together configuring the Technics the same way, even dug up the manual online.
I get sound from five speakers but no subwoofer....there's a line out for the Subwoofer but the Sony doesn't respond.
Sounds to me like the subwoofer section is fried in the amp....anyone else had this problem before?
The RCA output for the subwoofer is for a powered subwoofer (a subwoofer that has its own built-in amplification). I have used a Klipch powered subwoofer for a number of years with very good results.

THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.
