Michael niman sicksane1. Do you have the user manual? If not you should be able to find it online. What does it say about that message?
I don't know what it means but the first thing I'd try is to check the speaker connections. Make sure the speaker cables are firmly gripped by the speaker terminals both at the speaker end and the receiver end, and in particular, check for any stray bare wires touching each other and creating a short circuit, or any damage to the cables along their length.
Jillian Stapleton. Swerd Audioholic Warlord. Old Vet said:. Front of the speaker says "impedance ohm". Thanks guys Such a wealth of knowledge to draw upon. I'll be making a trip to a local audio shop soon to talk with them and have a look at power amps. Otherwise I'd need a pre-amp as well. That right? Am I seeing things correctly? The power amp would just power my CV's I just got?
And that amp needs it's own vol control. Or am I out in left field somewhere??????? I'm quite curious asto "the guys" reasoning here. Assuming the receiver you will be getting has official preamp outputs, and you say that Denon DOES have them, your volume will be controlled by the volume control on the receiver itself. Your power amp does not need them. IOW, the preamp is already in the front part of the Denon and is already running the show.
So, assuming you have the new power amp connected to the front right and left channel preamp outputs, and the big momma CV's connected to that power amp, and the rest of your speakers remain connected to the Denon, the Denon's volume control will control everything. Great Mark That's kinda what I was thinking This "guy" said it wouldn't work that way and I'd need a power amp with it's own vol control for the "big boys". That's good news.
What model are you talking about? Seriously, always talk with a make and a model number so that we can give you the facts as best we know them. Most Denon receivers don't have preouts on them. The AVR, despite it's age, is a decent preamp. You won't get any of the benefits that are available with HD audio that can be delivered over HDMI only, but you can feed it digital coaxial and toslink connections for true surround sound, and if you have an equipped player, you can hook up the analog audio inputs.
It has 7. The Denon will act as the preamp and adjust volume on those RCA connections just fine. If this is a typical design, then the internal amplifiers will be available at the same time as the preouts are available and you can connect speakers as appropriate. That amplifier, I would say, is not one bit better than the JVC you already have. It may be better, but it certainly isn't much better. It is not listed as 4 ohm stable, which means it will overheat and shut down when used at higher volume with a 4 ohm load sound familiar?
The external amplifier is the way to do things if you want good audio levels without shutdown. A quality amplifier is key, not some random specifications. The Denon, at least, can give you the preouts you need to take your sound to a good amplifier. Great info thank you very much. Something still not clear to me is the 4 ohm vs 8 ohm business. As for the Denon I'll have in a couple of weeks: "It is not listed as 4 ohm stable, which means it will overheat and shut down when used at higher volume with a 4 ohm load sound familiar?
Are they 8? Does the impedance vary and flop back and forth from one to the other When and why? And what would these impedance variations do to the amp?
So many questions huh? LOL Sorry. Receiver blocking: Radio receiver blocking occurs when a strong signal close to that being received reduces the sensitivity of the receiver. It is very important, especially in these days where there are many short range, and other longer range wireless cellular and other radio communications devices around.
It is quite likely that other devices will be transmitting a signal physically close by, and often on a channel that is relatively close. If the receiver is desensitised, then this can degrade the performance of the particular radio communications system in use. Intermodulation performance : Intermodulation distortion and intermodulation performance are important parameters for a receiver performance.
The presence of intermodulation products gives rise to unwanted signals being generated which may mask the wanted signal. Selecting the right electronic components during the RF design phase of the project is essential for good performance. Intercept point: The Intercept Point, or possibly more correctly, the third order intercept point gives an indication of the strong signal handling capacity of an amplifier, mixer or overall radio receiver. It is the level on a graph where the level of the third order products equal the wanted products, i.
Although the third order intercept point is an imaginary figure and cannot be measured directly, it provides an excellent figure of merit for strong signal handling. Cross modulation : As the name implies, cross modulation manifests itself by transferring the modulation on one very strong signal onto other signals being received. Cross modulation is not a specification that has major importance these days as it is mainly noticed where strong amplitude modulated signals are present.
One of the key elements of any receiver that governs its overload or strong signal handling capability is the RF amplifier. Its performance is key to the performance of the whole receiver. Under normal conditions the RF amplifier of a radio receiver should remain linear with the output remaining proportional to the input. However, even the best RF amplifiers have limits to their output capability. Beyond a certain point the output can no longer rise in proportion to the input as the amplifier enters a region where compression starts.
When this happens the output starts to limit and it is less than expected of a perfect amplifier. Compression in itself is not a problem for receiver overload performance. The absolute values of a signal are of little value and in any case the automatic gain control, AGC, used in many radio receivers means that the gain is reduced when strong signals are being received. It is the side effects of compression give rise to major problems.
