OK, another question. Hope it doesn't sound too stupid.
Let's say I have my receiver sub level set to the default of 10. My receiver goes from 0-20 for the sub level. Does the volume of the sub go up as I turn up the volume on the receiver when the SUB has it's own volume control? I notice that when I up the volume on the receiver that the sub
level doesn't change. How then can the volume of the sub increase when I am not changing the volume control on the sub itself? Does any of this make sense??? I have the EP500 by the way.
If you've got the sub hooked up to the sub/lfe output on the receiver (not some jury rigged sub to the tape out or something), then yes.
yes what? Yes, the volume on the sub goes up with the rest of the speakers when the volume on the receiver is turned up? My question is more in the area of
how does the volume of the sub go up when the sub-level stays the same and the sub volume knob isn't being touched?
The receiver outputs a slightly hotter signal to the sub.
Joey,
If you turn up the volume on your receiver, the sub volume should increase. Are you saying it doesn't? If it doesn't, maybe whatever you are playing does not have bass content.
Not at all...it increases. I have it connected properly to the LFE out. I'm just curious as to how the volume on the sub is able to increase when all the settings are remaining the same? Like I said, it's probably a stupid question
In my mind the volume of a speaker goes up when the wattage goes up by reason of the volume knob being turned up. But the sub is not getting wattage from the receiver (I think) as it is only getting the sub-level signal (which remains at the default of 10.) Now if I up the sub-level then the volume will increase and of course if I up the volume knob on the sub itself the volume will increase. But HOW can it do so if only the volume on the receiver is turned up?
Sorry if this is a waste of your time...
10 dB is not absolute; it's an (estimated, I would wager) boost against the gain at 0 dB. The gain on the sub output is always variable.
Joey,
The wattage doesn't only go up when the volume is turned up. Music is dynamic. Some parts are quiet and others are loud.
Maybe I still don't understand your question.
The main volume on your receiver controls the volumes on all of the channels.
What do you mean "...how is it doing this when all the other levels are remaining unchanged?". What "other levels" are you referring to?
Maybe you should draw a diagram so that we can see what you are trying to say
.
This has pretty much been answered, but I'll explain it a different way.
On this chart, the blue bars represent the dB level of each speaker as measured from the listening position with no correction or calibration applied in the receiver. The orange bars represent the amount of correction applied in the receiver during the calibration process in order to get the speakers to the same level (again, as measured from the listening position). The thin horizontal line at the top of the graph represents the "reference level" to which the speakers were calibrated.
Let's say that the sub was set to 10 (like yours is) in order to get it to the reference level. The other speakers needed different levels of correction -- some more, some less -- as you can see. These correction levels are stored in your receiver and allow the receiver to give each channel the proper level of signal so that they play at the same loudness relative to each other, regardless of the master volume setting.
Any clearer, or did I make it worse?
If the line level to the sub remains at 10 all the time, how can the volume on the sub increase just because the volume on the receiver is turned up? The volume on the receiver increases the watts to the speakers hooked up with speaker wire, not a coax cable.
I'm going home, I'm hungry. Sorry for the dumb question.
The line level on the sub doesn't remain at +10 all the time. It remains at +10 relative to the other levels.
Some more clarification. The volume adjustments take place at a point in the signal path in front of the amplifiers. The location of the amps is irrelevant. It just so happens that the amps for all the channels but the subwoofer are contained in the receiver. If your receiver has pre-outs, the master volume knob will affect all those line-level outputs, too.
Nice graph and explanation, Peter. You should be a technical writer
.
I moonlight as one at work, if only because I'm the one whose least reluctant to document processes in my group.
Wow, some nice pictures here- maybe you guys should be writing the technical manuals.
Yes, the settings in your reciever are just trim settings, so that you can get everything balanced/equal to each other. Then the master volume changes the volume of everything from there.
Joe, the first point is that the volume control on the receiver doesn't do what you think it does; it doesn't directly increase the watts which are available for the speaker to use. It's a variable resistor which varies the percentage of the voltage which comes in to the receiver(e.g. from a CD player)which gets sent on to the following amplifiers, either the built-in receiver amplifier for the speakers or the amplifier inside a powered subwoofer. The voltage from the CD player will vary widely, depending on how loud the music on the CD is at the moment, from less than .01 volt to a maximum of maybe 2 volts, but lets say that it's exactly 1 volt at this point. Next, lets say that at a certain point on the receiver volume control(not necessarily half-way)it lets 50% of that 1 volt through to both the speaker amplifier in the receiver and the amplifier inside the sub. If the music on the CD got louder and the CD player outputs 1.5 volts, at that same 50% volume control setting both the speaker and sub amplifiers would get 50% of 1.5 volts(i.e. .75 volt instead of .50 volt), and both of the sets of amplifiers would amplify that increased voltage, so both the speakers and the sub would get louder. If on the other hand, the CD output remained at 1 volt, but you turned the receiver volume control up to a point where it let 75% of the voltage through, both amplifiers would again get the increased voltage(e.g. .75 volt), amplify it, and again both the speakers and the sub would get louder.
The sub output control on your receiver, which you say is numbered 0 to 20, is a separate matter which adjusts the sub up or down in relation to the speakers, but as described above, both get the increased voltage for their amplifiers if you turn up the receiver volume control and so both get louder.
Hi Joey,
Thanks for the pictures and congratulations on your new HT.
I noticed you have the side speakers mounted very forward. I am curious how that sounds during movies.
Your centre looks very high to me. How does it sound? Have you tried tilting it down a bit?
I loved your use of gradient to give the knob a 3D look, Mark, but no amount of special effects can save a movie with a crappy plot.
Do you have an option of moving the couch forward a bit so the side surrounds are closer to the ideal position? I'm guessing if your sitting in the rocker it would be a much better experience than on the couch alone the back wall. The Q's are forgiving, but not sure that much.
I was curious about the sides because I have mine mounted slightly behind me. I've thought about moving them forward but then I'd have wires showing and I'd have to patch the walls in my new room.
NICE setup!
I'm envious of your TV. How far back do you sit? (I know you answered that already somewhere but JP is late with my meds). Is that a 720P or 1080P set?
What do I win?
