Yamaha RX-A700 loss of pre-out output

There has been a sudden loss of output to the main/front speakers which are driven by an external amp the signal of which comes from the Pre-Out. The external amp is fine, and the receiver is otherwise OK. If have the receiver set itself up automatically using the microphone, it has to increase the output to the main/front speakers by the max (10db) and decrease the surround and center speakers by the max (10 db) but then the mains are bass-heavy and muddy and still the output is low. Previously everything worked fine and all speakers balanced out to within 2 db of each other. I cannot correct this with any of the settings. Is this a setup issue or does this represent a component failure?

SOURCE: Loud distortion on Front Channels

Well, the nice thing about the newer amps is that the actual amp circuitry is all contained in a module and you don't have to do much troubleshooting. Just replace the module for that pair of channels. Bad news of course is the modules can be pricey. Should say right on it the part number, order it from mcminone.com or whoever, solder it in, use new conductive grease (many times I think these modules fail because the grease gets old, the module overheats and toasts) and you should be fixya'd

SOURCE: Technics SH-AC300 Connection to Power Amp & Pre-Amp

Hi!
The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.

SOURCE: Speaker output

Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.

SOURCE: Pioneer audio receiver pre-amp output

It is possible then that the root cause may not be electrical, but acoustic if you're noticing the issue from your listening position.
If you can run a channel test signal identically one channel at a time by positioning your meter less than a foot away and exactly the same distance with each speaker and the level differs by more than 1/2dB, then it's not the acoustics.

I want to run from my rxv2600 to a eq to an external amp to a pair speakers? yamaha online said run out of L/Rfront preamp to eq but i get no sound? Help plz am i missing something?


Must be connected to an audio OUTPUT.
There are probably preamp inputs and outputs.
Sounds a little strange, but signal (sound) must travel OUT of the Yamaha, IN to the EQ to be processed, OUT of the EQ, IN to the external amp to make it big enough to drive speakers, and OUT of the amp to the speakers.

How can I connect Senheiser wireless headphone to Yamaha RX773 without using front headphone jack as this mutes speakers, I have hearing problems, my wife doesn't, I tried both av audio outs in the back...


Your receiver has Zone-2 functionality. For Zone-2, it has both speaker (powered) output and pre-out line outputs. According to Yamaha FAQ, these pre-out outputs are independent on the main volume settings. So if your wireless headphones have their own volume settings, you can change the volume independent on speakers volume.

If you want same volume for speakers and headpohones, use the PRE-OUT FRONT outputs on the back. If you want different volumes (and listen to headphones even with speakers muted), use ZONE-2 OUT outputs on the back.

How do I connect the Bose Equalizer (for Bose 901 Series VI speakers) to a Yamaha RX-V850 RS? (not as a home theater) Thanks


If you get a second amp for the 901's you can have your cake and eat it in front of the TV too.

http://www.retrevo.com/support/Yamaha-RX-V850-Receivers-manual/id/320bh027/t/2/

Two solutions:

ONE: dedicated 901-RX-V850 stereo-analog-audio only:

If you want to have the Yamaha also support non-901's as the second set of Front Speakers, put the Active Eq in one of the three selectable Tape Loops. That way you can dial the 901 EQ out of the equation and select the 'normal' speakers for your Dolby Surround video experience.

Now imagine this:

TWO: 901's for the Front on a 100wpc stereo amp, your RX-V850 or a nice digital AVR driving center and rear, maybe 'normal' fronts, too

Get a nice 100wpc amp with its own volume control on eBay and slave it off the Yam. Remove the Front Pre-Main jumpers and place RCA Y-splitters in there so the pre-main connection out is maintained but shared with the Active EQ, which is in series with the 901's dedicated amp. Use the new amp's volume to match the 901's to everything else and you just have to turn it on or off to enjoy the 901's along with or instead of the 'normal' front speakers. You could even just disable them at the Yam.

Now for some boilerplate I created to get your creative juices flowing ij case you have a digital AVR in mind for the future:

Having a 901-based multichannel setup myself, I would highly recommend getting the Full Monte for video listening (below)...

In that case a separate stereo amp for the 901's would work. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.

Then set the new amp's volume control (if it has one, mine doesn't) to something HIGH and run through your speaker setup routines on the Yamaha. After levels and distances are set the Yam will be the boss of the 901's. I recommend sharing or directing any LFE with them. With 901's don't even need subwoofers but they don't hurt.

I've done this in my own setup once. Turn the 901's around so the rear faces point into the listening area. Crank up Master and Commander and when the waves are crashing or cannon are firing you WILL FEEL A BREEZE from them. Now THAT is multi-media!

How to connect microphone to Yamaha RX-V365 as a PA system.


Home-theatre receivers don't have microphone inputs. If you want to use the receiver as an amplifier in PA system, you need to use some kind of mic pre-amp or a mixer with mic inputs.
For PA mixer is needed anyway almost every time and all mixers have at least one mic input (with a pre-amp). Mixers have line-level output(s), which you can connect to the analog input of receiver.
Using receiver as an amp in PA has advantage that you have 5 channel amp. When using high sensitive PA speakers (as oposed to less sensitive Hi-fi home speakers), you can get good performance with the power rating of receiver. You could even use 2 separate channels for subwoofers and 2 channels for satelite speakers - but for that you would need a receiver with 5.1 analog inputs and special device called crossover which would divide the output from mixer into low-frequency signal and high-frequency signal which you would then connect to the front and rear analog inputs. But with RX-V365 you can use only 2 channels with analog input

I have a Yamaha RX-797 reciever and wish to install an outdoor speaker system through the zone2 outlet. Do you know if I can go from the zone2 outlet through the coupler jacks to the speakers so I can...


Hello sounds like you want to take the low level zone 2 output and run it to the PRE AMP in?

If that is correct the onboard amplifier will power your speakers but will no longer provide sound for your main channel as you are removing the "loop" which send the front L & R signal to the amp.

Your best bet is to find an inexpensive secondary amplifier.

Sonance makes a sonamp 260 or 260x3. These are available on ebay for under $100 and work great for multiroom applications.
A 260x3 would give you 3 speaker outputs allowing you to run not only to your patio but also to two other locations and includes a switch to turn each zone on/ off.

Hope that helps

I would like to know how to connect my Bose 901 to my Yamaha RX-V765 AV Receiver.


Ahhh, the good ole Bose 901. (I like those)... And you want to connect them to the Yamaha RX-V765 AV receiver. That should be a piece of cake. I assume you only have two Bose 901 cabinets. If so, you simply need to connect one end of your speaker wires to the terminals found on the 901 cabinets, and the other end of the speaker wires need to go to the Front Left and Front Right speaker outputs of the RX-V765. The RX-V765 is a 7 channel surround receiver. Weather you run it as a 7 channel theatre or as a more classic 2 speaker configuration, you will want to run the 901 cabs from the Front L and Front R speaker outputs, unless for some reason you want to specifically use them for any of the surround channels in which case it will not harm anything if you use them for surrounds - it's just that if you're simply wanting to use them as your principal speakers, you want Front L and Front R.
So connect them as I explained, power the receiver up, put on your favorite CD and enjoy!

Can I hookup a Bose 901 EQ to my receiver and amp?


Your instincts are correct. In fact, the only way the 901's can live in an A/V system is with dedicated amplification.

Put that old amp back to work.

This is exactly how mine are connected.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ's Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

Yamaha RX-V2700 no sound from any speaker outputs


Make sure that you have the correct input signal selected.
Also, check if the sound is not muted.
If you have a multi-room speaker switch, make sure it is set correctly to main speakers.

Yamaha rx-797 w/Yamaha ge-60 eq utilizing prein/main out ..and ad


It sounds like you want to use the external amp rather than the internal one. If that is the case, just connect the output of the EQ to the input of the external amp. All you are doing is inserting the EQ between the amp stages now. Using the mx-1 rather than the internal amp is no different.
