It doesn't have a specific low-frequency or subwoofer output.
Depending on your unnamed subwoofer we may be able to work something out. Any sub should be able to work with a full-range Line Level feed.
If you use a Line Level input you won't have volume control of the sub through the receiver.
That would be available at either Tape Out or Aux Out. Just run an RCA pair (or combined to one male out if that's what the sub amp requires).
Whichever one you use, you won't be able to activate that function for listening as it would remove the input to the sub amp.
If your sub accepts speaker level High Level inputs you could drive it with speaker outputs and yoi WOULD have some volume control, assuming the sub had a way to match its initial volume to your other speakers.
Of course, the manual for your sub might explain some of this, too.
Setting the RX-V861 remote control to operate Zone 2:
Using a ballpoint pen or similar object and press the [CODE SET] button RX-V861 remote control. The[TRANSMIT INDICATOR]on the remote should flash twice.
Using the [NUMERICAL KEY PAD] on the remote and key in 9992, the [TRANSMIT INDICATOR] should flash.
Assigning the receivers internal amp for Zone 2:
Set the remote control selector to [AMP]. (Located to the right of the volume buttons on the Remote.).
Press the [SET MENU]button on the remote control.
Arrow down to Manual Setup and press the Enter button on the remote control.
Arrow to the [SOUND MENU] option and press the [ENTER] button on the remote control.
Arrow to Speaker Set and press the [ENTER] button on the remote control.
Arrow to the EXTRA SP ASSIGN and select ZONE2
Press the [RETURN] button on the remote control to exit out and return to the Manual Setup.
NOTES: There is an option for setting the Maximum Volume and Initial Volume in the Zone Set menu.
Max Volume: This is an optional feature but isrecommended to prevent the accidental change in volume levels thatcould damage the speakers and receiver.
Initial Volume: This is also a great feature that would seamlessly start the volume level for the second or third zone at the desired level.
We do not recommend using any Speaker Selector boxes to enable more than the recommended number of speakers per terminal. Controlling Zone 2 using the RX-V861 remote control:
If the Main Zone on the receiver is on, press the [POWER BUTTON]down and while holding that button down press the [PHONO]/[**] button on the remote. The [TRANSMIT INDICATOR] will light up.
You will not be able to use the following buttons on the remote: (Pressing any other button will cause the remote to exit Zone 2 mode. [POWER], [STANDBY], [VOLUME], [MUTE] and the [INPUT SELECTOR] buttons [DVD], [CD], etc.)
There are the instructions as written straight from yamaha. If you need any further assistance please let me know. Thank you, Lee
Any powered sub-woofer will work with it. Check the back of the Technics, make sure there is an RCA output labeled "Sub-woofer" or "Woofer" or "Sub". If so, you can get any brand of powered sub woofer and it will work. A powered sub-woofer is one with an amplifier for the sub built into the box and you will need to plug it into an A/C outlet as well. The only exceptions to what will work with this unit is to make sure you are not buying a sub-woofer that is made to only work with the companion unit it is originally sold with. Many Panasonic and JVC sub woofers are like this. Just look for a sub-woofer that is not part of any system. Velodyne makes some really great sub-woofers that would work nice with yours, but they can be a little expensive, but they are very good.
If your Technics has no RCA output for the sub-woofer, you will need to make sure that whatever powered sub-woofer you buy has a speaker level input for it. Most powered sub-woofers have this feature, so that you may just run the front speaker outputs of the receiver into the subwoofer and then the sub-woofer will have a set of speaker outputs right below the speaker inputs so you can still have your front speakers connected to that and not loose anything from your system.
I hope I have explained this in a manner you will understand easy, if not just post whatever questions you may have right on this thread and I will get back to you as soon as possible.
It would also be appreciated if you could rate this solution if you no longer need any help from me. If you do require more help, please wait to rate this until we are finished. That way I do not get an undeserved bad rating when we have not even finished our communications. By the way, A "Thanks for trying" and "Helpful" rating are really not good, they always end up lowering my overall score.
This set is getting old and is in the Archives section of the Yamaha consumer guide area. But, you can still download the owners manual if you need one.
If it is going into protection mode even when there are no speakers connected OR when the sound level is very, very low or zero it is not good news.
Yes, unplugging the line cord will cause the protection system to reset itself. But, if it shuts itself off again soon after rebooting it is a sign of bad grease in the output stages -- in all probability.
Let me explain: The audio output transistors are mounted to a large heatsink which keeps them cool during operation. They are electrically isolated from touching the heatsink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise; as the heat goes up they conduct more current and cause the protection system to activate and shut the set down (in order to avoid damage to the set).
That is the most common cause of your symptoms. However, there are several other possibilities, but I give this explanation a 90% probability based on my experience.
