HTR-5740 Subwoofer Hooking Up Issue

MAke sure you have the lfe output enabled. Or you could try to use a headphone to rca adapter from a cd player/phone to test it directly.

You need a long enough subwoofer cable ( Male connectors on each end ) and connect it to the female RCA input on the sub and the rear of your receiver has an output labeled subwoofer out connect the other end of the cable there and you are good to go. Make sure both the receiver and the subwoofer are powered off when making the connections.

The Yamaha can only drive powered subwoofers. Make sure that the RTD250 has it's own amplifier built in, you won't be able to easily run it off the yamaha if it doesn't.( the powered subwoofer will have a mains cord to power if it's correct) If it doesn't have a amp built in, easiest weay is to buy a cheap powered sub.
Is the RTD 250 the sub fromthe RCA home theatre pack?

as long as there is a speaker out from the receiver you should be ok just make sure polarity for spkr is right --remember you workng with AC current bad wire will cause fire==

Subwoofer needs to be enabled through menu on Yamaha. LINE OUT might be turned off or Subwoofer volume set to low or off... (-db level) kinda thing...speaker wires are usually always live etc...

Please change the cable which goes from the subwoofer to the AV receiver. Buy one good quality cable this will sove your problem. As i was facing the same problem and i myself resolved the issue.

i have the same tuner.on the back you will see all connectors bottom row of rca jacks you will see subwoffer if your sub has to rca. red/white use a splitter monstor cable gold ..works best. i use Home Theater Reserch speakers... you can also plug your subs power plug into the tuner snd you never have to power it on seprate .........

Hello srqwrk,

You can connect the VX7 to the 5730 using an RCA Y cable like the one shown in the picture below. You get your one connection for the receiver and 2 for the VX7. These are available at any electronics store. Remember that the cable should be long enough to go from the receiver to where subwoofer will be placed.
Hope this helps. Let me know.

Well, as I know, your Cerwin Vega subwoofer is designed for use with stereo systems. Therefore, it has only 2 channels for input, and 2 channels for output as well. However, you can try this out; the first thing I suggest is that you hook up your main front channels through the subwoofer. All you have to do is to connect the subwoofer input to the front channel output on the amp, then hook up your front speakers to the satellite output on the subwoofer. As long as you make sure that system is working on 8 ohms, I believe this can activate the subwoofer.
