Well this can only happen due to a few reasons, they are, the audio amps, audio amplifier is faulty. or the leads aren't conducting the current to the speakers, can you test these leads on some other speakers?
Often the Power output amplifier "Blows" due to various causes, also it may have something to do with the power supply too. you need to check, if it's on, and if it is actually outputting a signal at all.
If possible try another set of speaker on the unit.
Really the only way to test is by substitution of components to prove where the fault is.

Having trouble under standing rms with speakers. Some speakers rms is per speaker and other are for both speakers.I am looking for soundstream speakers that would be 150 rms per speaker. Thanks


rms is a method of measuring power (wattage) delivered from an amp to a speaker. In almost every case, wattage capacity of speakers is quoted PER SPEAKER. Likewise wattage output is quoted per amp output channel. Assuming a you plan on a single speaker on each output channel of your amp, you should be in good shape if your speaker wattage capacity equals or exceeds your amp's output rating. I've never seen speakers rated as wattage per pair.

(rms is the dominant way of measuring average watts of an ac sine wave signal)

Magnavox LCD tv external speaker


Hello
The jack you describes here "Digital Ouput Device To" means, you can connect these jacks to the output of a digital device, such as DVD or so. It is meant for to get signal into the TV, not ot out.
HDMI [High Definition Multimedia Interface] is a type of connection, which the TV an be connected to any HDMI device from outside. Both the above said are, signal in to TV connections. Not out.
If you want to connect this TV to any amp or any other external audio devices; look for any audio out option is there.

the unit is ok. User manual on page 42 says that the digital sources can not be output trough multisource output.
Try to use VCR-1 VCR-2 audio output jacks instead.

I have an "ilife" Which


You would be tempting fate.

There is usually a reason a given connector doesn't accept bare wires. RCA conenctors not only amke better physical and electrical connections but they make sure ground is to ground and signal is to signal and neither touches anything else.

There are no outputs provided for either signals or speakers.

Good signals to the amp, one channel has no output


check the bad side with a known good speaker first.If it still doesn't work most likely burned out that side. Usually a power IC chip depending on model.

Apart from the "line input"


input and output are for low level ( as with RCA cable connectors) ,, the speaker connections are for high input, (red and black connections. ) you can run the mains to the (rca) from your receiver to run the sub woofers, and from that use the speaker wire connections, to go to the left right speakers, (out only not in) this is done if you want to run the subs and the Rt/lt/ speakers , eliminating the speaker connections coming from the receiver. which you could use for 2 additional speakers if you want

OVERLOAD


First of all the KEF is a powered sub which means that it wants a line level signal NOT a speaker level. Send the signal from a tape output or pre-amp output to the sub input. The overload is because the impedence load for the speaker output is too low and looks like a short to the amp. Continued attempts to connect the system as described will result in damage to the output section of the amp.

Please let me know if you need more info.

MPA-101 Amplifier powers on, receives source signal, the fuse is not blown inside, but no sound comes out of the amplifier. The amp is pretty new, doesn't even have dust inside the unit.


Hello, is this a Radio Shack PA amp or Jamo amp? The unit is probably in "Protect" mode. Is this a PA system or a receiver...receivers have a protection circuit that will not let the speaker relay activate if the amplifier output section is shorted and sending voltage towards the speakers...so they won't fry!!The speaker relay should activate within 3 to 5 seconds if your output section is ok.

Can I connect a power amp to this unit?


If your 2100ES has a selectable INPUT AND OUTPUT and if you're intending to send all signal to the power amp, i.e. not bi-wiring or using the 2100ES to run mid-range or treble then you simply send Left & Right audio (White & Red cable) from a 2100ES output, probably AUX OUT ( it doesn't really matter apart from Phono on some units) straight to the power amp on AUX IN.
We should be just dealing with audio here, so connect the NAD audio output to CD or DVD IN. Select CD or DVD IN on 2100ES input switch and switch output to AUX OUT (whatever you decided goes to the power amp) on the 2100ES. Turn power amp to AUX IN and it will now get an audio signal from the 2100ES for amplification.
Speakers connect to the power amp as a normal amp, so pos and neg etc. The 2100ES now only acts as a signal feed, the power amp does all the work.

So, summary - switch on the NAD, press play - video goes separately and audio goes to the 2100ES. Turn 2100ES to INPUT for NAD. Turn 2100ES to OUTPUT allocated for power amp. Turn INPUT on power amp to allocation for 2100ES.

Turn it up!
