Yamaha RX-V679 Owner's Thread

Was busy posting under another thread (677) when I realized my AV was a model ahead.

Is it bad policy to start a new thread on a slightly different model? No offence taken if you want to point that out!

Anyway ... assuming it's ok ... just want to find out whether this unit supports video air drop from an iPhone etc. When I try it, all I hear is the sound. Shouldn't it be easy to see the video too? If anyone has any tips on that, be most grateful!

I was seduced into buying a 679 yesterday bacause Richer sounds only had un-boxed 677s with no remote left. But I'm well pleased. I have an old speaker system which I'm not going to replace and they are a set of Bose Acoustimass 10s. Now I'm at odds as to what I set them as on the receiver, Large or small. I don't really understand what the receiver is asking so because they are small in size that's what I've set them at but I'm probably way off the mark. Does anyone know please............Thanks in advance...............dennis

Set speaker sizes to SMALL irrespective of size. Read the following for the reasoning as to why:

Small vs. Large


Do you have a subwoofer in your system? Great. Then your speakers are small. Before you get all upset, read on. This is one of those audio myths whose time has come to be busted. To understand why, we need to talk about Bass Management.

In the early days of home theater it was thought that in order to reproduce the full movie surround experience at home it was necessary to place 5 large loudspeakers in the room. The reason for the size was the woofers. To play at theatrical reference levels and reproduce the deepest bass available in the content requires each speaker to have 12” or larger woofers. Let’s just say that this theory didn’t get very far in the real world.

A better and more practical approach came after studying human perception. The mechanisms that we use to determine the direction of arrival of sound depend on the frequency. At high frequencies the wavelength of sound is small and so sound coming from the side is shadowed by our head. That creates a level difference between the sound reaching the ear closest to the source and the ear on the other side. Our brain analyzes these level differences and produces an estimate of where the sound is coming from. But at lower frequencies, the wavelength of sound gets longer and our head is not large enough to produce a level difference at the two ears. Instead, we analyze the difference in time of arrival of sound at the two ears. Sound arrives first at the closest ear and we use that to determine the direction. But even that ability fails us below about 80 Hz. The wavelengths get very large and it was found in listening tests that 80 Hz is the frequency below which most people can not localize the direction of sound.

Taking advantage of this apparent “deficiency” in our hearing was what made home theater practical for millions of homes. Five satellite speakers of reasonable size could now be used because they no longer required large woofers. A subwoofer (or two) can reproduce the lower octaves and it can be placed out of sight since its content is not directional.

But there is also a practical advantage: directing the bass to a dedicated subwoofer channel with its own amplifier greatly improves the headroom in the main channels. The idea behind this was proposed in a Society of Motion Picture Engineers (SMPTE) meeting in 1987. The participants could not agree on the minimum number of channels required for surround sound on film. Various numbers were being shouted out until a voice was heard from the back: “We need 5.1”. Everyone’s head turned around to look at Tom Holman. He proceeded to explain what he meant: Take the low frequency content from all 5 channels and redirect it away from the satellite speakers to the subwoofer. If we do the math, then the content below 80 Hz is 0.004 of the audible 20,000 Hz bandwidth. But 5.004 didn’t sound as catchy so Tom rounded up to 5.1. By the way, don’t make the amateur mistake of calling it 5 dot 1. It is a decimal: 5 point 1.
Fast forward to the early 90s when the first DSP powered home theater receivers started to appear. Along with progress came complexity. Some industry forces believed that Bass Management should be an option that could be turned on and off by the consumer. That’s not necessarily a bad idea, but to make an informed decision requires much more knowledge about the system than what was available to the typical consumer. So, the Large and Small rule of thumb was established. The idea was to look at the size of your speakers and decide whether their woofers were “large enough” to reproduce the lowest octaves at the required levels. It was a noble thought, but looking at it 15 years later I believe that it has led to nothing but massive confusion. The poor consumer was led to believe that Large is somehow a good thing and was then left wondering why there was nothing coming out of their subwoofer.

Redirecting the bass to the subwoofer relieves the receiver amplifiers from having to work on reproducing the low frequencies and this greatly improves the headroom. If you happen to be using Audyssey MultEQ for room correction, you will achieve much better low frequency performance because the MultEQ subwoofer filters have 8x higher resolution than the filters in the other channels.

Here is a better rule: All speakers are Small. In today’s complicated AVR lingo that just means: If you have a subwoofer you should always turn bass management on. Always. Even if your receiver clings to the past and automatically sets your speakers to Large.

Thanks for the reply dante01. Just bought some banana plugs from RS for the speakers but they don't fit. Are the terminals on the 679 designed for bananas? Sorry for the basic questions..........ta

Remove the small plastic bungs from the centres of the binding posts so that you can then insert banana plugs.

There are bungs on the back of my old Denon 1909 but there are no bungs on the back of the 679 just a smallish hole?

The small hole is in the bungs on the RXV679. Remove the bungs that have the small hole in them and 4mm banana plugs will fit the binding posts.

I've just bought one of these to replace my aged sony STRDB780 that I bought in 2003.

I'm only going to be running this 5.1 which the manual says it's happy with this but then doesn't give any indication of any special settings to tell it that it's in 5.1. Does it automatically recognise that it's in 5.1?

That's my current amp the Sony 780. Wow I didn't realise it was that old! I'm due an upgrade too and the Yammy looks like the best overall bet. I hope you're pleased with yours? Please let us know how it compares with your old one. I'm looking forward to having HDMI inputs eventually!

As for your question about 5.1, I'm no expert as I don't have the amp yet but I would imagine if you only have 5 speakers plus your sub connected then you'll be in 5.1 mode. For 7.1 you'll need the other 2 speakers connected! Cheers.

Tell me ... think I'm going a bit mad here ... but where do I put the coax cable with the RX-V679 ... the one that in my old 'just a TV' days used to plug straight into the back of the TV? It carrys the signal from the roof aerial ... and although we primarily watch Sky via satellite, it'd be nice to have it as back up in case something goes wrong with that! Also ... anyone got any clues on streaming video direct from an iPhone/iPad? It has those two products plastered all over the box, but I can't seem to get it to work. Your help as ever much appreciated!

The terrestrial aerial feed still goes to your TV's RF input. The AV receiver doesn't include a TV tuner and your TV is still the device used to deal with the signal you get via the antenna on your roof.

You cannot stream video content directly to the receiver from a mobile device. THe receiver's networking capabilities are restricted to audio and the receiver has no inbuilt ability to render and play video content. The inbuilt media player capabilities of the receiver are only applicable to 2 channel audio sources.

Thanks Dante ... of course, that was really dim of me! But what happens if you have a projector? Do you have to buy a separate 'tuner' box to handle that feed? What do people generally end up doing?

Thanks too for iPhone/iPad info. A shame ... but not to worry.

Yes, PJs don't tend to include the tuners you get with TV sets so you'd have to use an external device with inbuilt tuners. I'd maybe suggest a Freeview PVR if wanting to view freeview content via your PJ.

The Freeview aerial feed would go into the PVR and you could then connect this to your receiver via HDMI. The receiver's HDMI output would then be used to passthrough the video to the PJ.

Cheers mate, mine is still in the box, I'm planning on setting it up tomorrow. I will update o how I get on.

Your new receiver will detect whether you have 5.1 or 7.1 when you plug the mike in and do a test.

As dante rightly pointed out on the 677 thread my Sky HD box needs an update and this is not possible until Jan 9th when the Sky man turns up. Strangely on my old Denon 1909 I could receive Dolby Digital audio through the fibre optic cable but I think I had to assign something (still with no sky box update). I've plugged the fibre into the back of the receiver from the sky box but it don't seem to be doing anything which is annoying. Now not being a very technical person does anyone know a way around it until the 9th Jan? I was reading the 679 instructions trying to get my head around things and came across the term ARC! does that mean anything in relation to what I'm asking. Incidentaly I have a Panasonic VT65 plasma..................thanks in advance...........thicko

As was the case with your Denon receiver, you can assign the optical audio input to the HDMI video signal from the SKY box so that both inputs are treated as being one source. I cannot guide you through the process, but I'm sure someone else will oblige or you can look in the user manual for guidance on how to do this.

ARC stands for Audio Return Channel and is a feature of HDMI CEC. It allows audio sourced via an ARC enabled TV to be conveyed back to an ARC enabled AV receiver via the HDMI connection between them. This wouldn't offer you a resolution to the issue you are having.

As said, you have to associate the Sky HDMI input on the receiver with AV1 or AV4. Page 90 approx in the manual to configure Audio In, setting an HDMI video input with a different audio input. That should fix it until your box is upgraded. Make sure the Sky box sound settings Optical Output is set to Dolby D.

Press On screen
Select Input
Use cursor <> buttons to choose the Sky HDMI input
Use cursor ^ button to select Audio In
Try AV1 or AV4

r22flyer I think I've cracked it or should I say you have. I love these forums. Plenty of good advice with NO sarcastic remarks....................Thanks again mate :)

Set mine up this afternoon and I'm please with it so far. It has indeed recognised that I only have 5.1 speakers.

I couldn't work out how to get the tv to output sound using ARC but I'm sure with a bit of a read of the manual will sort that out. It works over optical anyway so it's not really an issue.

Spotify connect is good, I can see me using that quite a bit.

Slightly disappointed on how bright the display is though, even on it's dimmest setting it's quite bright.

Now I've got the Sky HD box going through the 679 I have a couple of questions
1) When you are watching programmes on the HD channel the display says Dolby Digital even when the programme is broadcast in 2 channel stereo and not highlighted in yellow showing HD?
2) When you press the straight button twice the display says DD PLII Music?..................

HD channel broadcast all audio using the Dolby Digital format. Dolby Digital can be stereo and not all Dolby Digital audio is 5.1 in nature. The PLII denotes the application of Pro Logic II surround sound processing which is producing pseudo surround channels for those absent from the discrete audio stream coming into the receiver. Discrete 5.1 Dolby Digital would override this processing. Many leave the PLII processing in effect for TV sources because not all TV broadcasts have 5.1 audio. THose broadcasts that do will override the PLII processing while those that are in stereo will utilise it to create pseudo 5.1.
