Question about Yamaha RX-V870 Receiver

1 Answer

Output volume varies, with loss of bass and clarity

Audio volume varies, with loss of clarity when on for a little while. If I remove either input channel and only play one channel, it comes back to proper volume. It does the same with either channel disconnected.
Q. Would this be related to the power output stages, and possible just the power tranistors?

    Thanks Dan - makes sense could be a power supply problem. Hopefully is just fault capacitors, or maybe the regulators. Might have a look at them myself and source some spares. Thanks and I will let you know how it goes.

This sounds more like a power supply problem. I would have the voltaeg regulators checked along with the filter capacitors in the power supply area.

How do I get the sound from my TV to play through this system?

Most audio receivers have types and several inputs available . The TV will likely have only two types. One will be the standard Red and White RCA connectors. Others may not have the RCA but a 2.5 mm headset connector. Some TV's will have an optical link connection. And a few will have a digital connection. The digital is a single RCA type connector but of a much better quality than the vintage.

The digital and optical; are the highest quality and would be the first choice for best audio/surround/Dolby. The RCA Red and White is next. The 2.5 mm headset is the least desirable.

Some receivers are programmable for the optical and digital inputs. You would need to reference the receiver manuals to determine the setup. The default setup will work but a little trial and error may be required to determine what input goes to what device. ie the DVD might be connected to the TV input (can be a little confusing)?

After connecting the best quality output of the TV into the receiver it is necessary to go into the TV setup menu to turn off the TV internal speakers and I would set the audio output to fixed. The variable output setting can be confusing where both the receiver and TV can set the volume.. The volume will now be set where the receiver can control the volume and not the TV,

B&k avr 7 with SACD inputs needs independent tone equalization settings

For your stereo configuration, refer to the preamp they are connected to for tone controls.
For your center and surround channels, refer to the B&K setup menus for those controls.

I have a Harmon Kardon HK 3370 Stereo Receiver and a Samsung LCD LE40C530F1W. When I connect the stereo Aux jack to the LCD Audio jacks ( red and white rf cables ) I get no sound out via the receiver.

Obviously make sure your stereo mode selector is set to AUX and the volume on the stereo is turned up at least a little when you test it.

If you still have no luck then try increasing the volume on the TV as well. You may have it set so that the level of the audio signal leaving the rear output connectors on the TV varies with the TV volume. That way if your TV volume was turned down or muted when you tested it, then you would not hear anything coming through your stereo.

There should be a setting in the AUDIO OPTIONS menu of your TV where you can switch between a VARIABLE AUDIO OUTPUT and a FIXED AUDIO OUTPUT level.

With the FIXED audio output level, you control the volume of the TV audio coming through the stereo speakers with the stereo remote only.

Otherwise it should work.

Good luck.

I recently purchased a Yamaha RXV467 and plugged it into a set of Mirage MX 5.1 speakers. I know from experience that these speakers are capable of quite remarkable crispness and clarity, and the reviews...

It sounds like you're electronically compensating for something terribly out of whack. If you require a lot of EQ heavily weighted at either end there is something very NOT-flat about room or the audio signal.

I'm curious, what is the difference between 'normal' program audio and adverts other than the usual increase in volume?

I'd start over with zeroed YPAO/EQ settings and try to figure out where in the audio chain the frequency imbalance is starting. Perhaps using headphones to remove speaker and room effects?

You could also tap the audio on AV Out, for example, and see how your TV sounds. EQ and YPAO would NOT affect any RCA output. If the audio is hosed there something deeper is at work. If not, the receiver is probably defective.

(I think) our bass player plugged from the output on a powered desk in to the input of our JBL MPro 18" sub (MP418SP) powered by crown Amplifiers. Now the fault light is constantly flashing and...

I'm assuming you mean he plugged an amp output (meant for a speaker) into the input of one of the Crown amps powering the sub-woofer. Right? Crown amps have good protection circuits and are high quality units. Some models have internal fuses but you didn't list a model here. If they are fused (or some kind of breaker) you should be able to see those by opening the top cover (amp off and unplugged). It is unclear if you tried to use the amp again after this incident.
Some Crown amps have protection circuits that will reset themselves after the fault is removed. In this case, you should remove both inputs and output (speaker) and power it up. If the amp doesn't light any protection lights or indicators, then turn it off and connect a known good speaker (not the subwoofer) and a source you can control. Set a low volume and see how it goes. You can really try either approach first depending on what's easier.

No volume from optical outputs were working fine.

I can't find any evidence that this unit even has any optical OUTPUTS. Nor can I lay hands on a manual.

If you mean optical INPUTS are having trouble, which ones? Just one? Start at that device. Try it on another input. Make sure optical cables are clicked in and have no kinks or tight bends anywhere.

Multiple? Receiver issue, possibly just a matter of assigning them. I have an old Pioneer and after extended power losses I have to go in and reassign everything plus speakers settings and levels. Food for thought.

Plugging a turntable into a harmankardon 147 receiver: where and how to get volume. The sound volume is too low.

The 147 receiver doesnt have an input for a turntable. THe output from a turntable is VERY low and is heavily equalized because of the actual record format ( the bass is cut way down and the highs are boosted.....when run through an actual phono input, it "un does" the equalization by boosting the bass and cutting the treble......this is called the RIAA compensation curve ).

You need wither a receiver with an actual phono input, or a good quality Phono Pre Amp....

Good luck... Rob

Very low ouput from subwoofer preout

The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
