Question about Samsung LN26C450 26 in. TV

1 Answer

I want to get a mono audio output from the TV audio sockets to combine the L&R channels to a magnetic loop amplifier. At present I only use the R channel) I want to keep the main sound as-is so that both systems will operate together or separately as they are at the moment. I want to avoid an active system ( stereo pre-amp or such) and was hoping the two outputs could be paralleled or a simple 'T' resistor network depending on the TV output configuration. Thank you.

I assume you are taking an output from either the "Phono" or "Cinch" sockets on the TV.
There are leads available that combine left and right channels to one output. All you do is buy a Phone lead with the correct plugs on it. The lead will be a stereo lead. Cut the cable and join the screen/braided outer wired together. Connect the TV stereo inners together and you have a mono output. The TV has a buffer to ensure no damage is done to the sockets. If you want you can use a pair of 10k resistors in a "Y" configuration but as it is not a balanced amplifier input, it really doesn't matter.
Just use one of the plugs for your Induction Amplifier and you will get a mono signal on your loop that contains all of the audio information.
Hope that helps.

Can I hook up my roku device to this tv If so what kind of cable do I need?


On the back of the TV/VCR unit there is an input for audio & video plugs. These will accept a composite video signal and mono audio signal. I'm not sure if newer roku has these outputs as they are low def only signals. The roku would need to have have red, white & yellow sockets. (Old Roku's had these....) Yellow is video, red and white are L & R audio. Use a y adapter to merge red & white together, and use a standard RCA patch cord to connect the roku composite outputs to the TV VCR inputs.

Hello, can someone help me, i want to know how to connect the wires if i want to use 2 channel instead of 4. THANKS IN ADVANCE!!!!!!!!!!!!!


You would want to bridge 2 of the left channels and 2 of the right channels, essentially combining the power output of the amp.

This article should help you out:
http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-bridge-an-amplifier.html

Essentially you will just be using 2 channels (left, right) instead of 4 (front left, front right, rear left, rear right) essentially combining the power of those outputs. You'll want to check the amp to see if it tells you which of the outputs should be used for the "bridged" method.

CAN I CONNECT BOTH MONITORS AND SPEAKERS (S215 AND SM'S) TO A YAMAHA P5000S AMP?


You could use this amp as effectively 2 separate mono amplifiers - using one channel to power the monitors and one to power the main speakers.
Alternatively you can run the amp in stereo connecting one set of speakers to the neutrik outputs and one to the jack outputs. In this case the amp output will be shared equally between the two sets of speakers, which are in parallel, and the combined impedance must be not less than 4 ohms.

No output from one ch on old JVC VN-300 audio amp in stereo mode, power stage seems ok as both ch work ok in mono mode.circuit diagram, anyone?


The stereo/mono switch in most amps mearly feeds one channel to both channals when in mono. However it does mean that the Power Transistors (or whatever does the main output) is working on both channels. Therefore the dead stage is in the pre-amp part. Remember that the two channels will have the same parts as each other. The advantage is that one will have working parts and the other wont. So you can compare the two channels with voltage tests, using a multimeter.

Marantz dedicated amplifier squeals


The symptom sounds like a feeback loop. As long as that indicator is showing near maximum output on one channel AVOID ATTACHING ANY SPEAKERS TO IT!!!! You'll cook the tweeters.


Turn it off and manually operate every control, knob and pushbutton throughout its range many times to wipe oxides away from their conductors.

Set all EQ controls to their midpoints and re-evaluate.

We don't know if it's an input or output problem yet. Does it do that with all inputs?

Bridging outputs on JBL BP300


Hello paulnkate,

The BP300.1 is a mono (1 channel) amp. You cannot bridge a mono amp. Bridging is a method of combining the outputs of 2 or more channels of a multichannel amp into a single mono load. On your amp you would connect a single sub to one of the +'s and one of the -'s (either one is OK, they are connected internally). The other pair of terminals is just for convenience, making it easier to connect, if you want to power 2 subs.

Hope this helps.

Mono to stereo


You can't convert mono to stereo since the TV only has a single input, and not the separate right and left channel circuits needed for stereo. If you are connecting a stereo source like a DVD player, what you can do is combine the right and left channels into one and connect that to the mono input. You need an audio Y-adapter with two RCA jacks going into a single RCA plug. These are available from Radio Shack. If you are outside the US, there should be local sources such as a stereo shop where you can find the adapter. This won't give you stereo, obviously, but you will have all the sound.

I have a mtx 421d. can I over heat if I connect only one channel.


Hello jaimemm_77,

The MTX 421d is a mono amp. It only has one output channel.

If you are asking about hooking up only one channel to the input, then no, the amp will not overheat. But the output will be significantly reduced. It would be best to use a "Y" adapter with a single female and two male connectors to split the channel into both inputs.

Hope this helps.

Subwoofers


This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.

Alpine PDX-4.100 3ch operation


use channel 1 and 2 as normal, use the positive from channel 3 and the negative for channel 4 as mono 1ch, your bridged output on the mono chan should be around 200watts at 4ohms.
