Can I use the 8 ohm output instead of the 70v output? I want to connect 8 speakers (I already connect the speakers in serial/pararell and get 8ohms

Yes, you can. You will not have the benefit of the 70v system, that is longer distances from the amplifier to have good quality sound. Just double check that the amplifier "sees" 8 ohms, and connect the speakers accordingly

Im by no means an expert but you can use the 8ohm output. However it may not produce enough volume to drive 8 speakers without distorting. The 70v is what I use to drive a 7 speaker setup in a restaurant.

Yes, as long as they are wired that way it should be no problem. I hooked up a 8 ohm speaker to test it and it seems to have plenty of power, especially if you are using them for background music.

This unit does have an 8 OHM output so it should support that. I personally have not tired these outputs, so I do not know what it sounds like, or if the unit would run hot.

I did some brief reading about how to match amps and speakers, and my understanding is that the amp's power rating should be less than that of the speakers--around half the peak rated wattage. But as well as power you have to make sure the impedance of the speakers matches the output impedance range of the amp. If you're running two 8 ohm speakers in parallel on each channel, that's actually 4 ohms, so check those numbers. We use this Grace BTAR122 in conjunction with two 80 watt Polk Atrium 4 speakers and it sounds fantastic.

Hi, nope, I wired them using "1 DVC driver with Voice Coils in Parallel". This is a 4 ohm dual voice coil sub which I wanted to run at 2 ohms for my mono block amp. You are describing wiring them in series which will give the speaker 8 ohms. I go positive to positive, negative to negative. Have the positive from the amp running to the + on one side and have the negative from the amp run to the - on the opposite side. Again, this is you want the speaker at 2 ohms.

You haven't provided all the necessary information to receive a worthy answer. We understand you want to power a pair of dual 15" speakers at 8 Ohms, but that's all we know. Complete your research by finding out the power handling ability and capacity of the speakers. Then, look again at the outputs that the amp is capable of. Your answer is then looking right back at you.I assure you this: Relying upon a bunch of people you do not know for answers to questions like this is going to come at a cost. You have no idea that they know anything about which they speak.

Won't work with a 8 ohm coil. I use it with a 12" single 4 ohm via bridge and the amps couldn't handle it. I think you should get a different amps or get 2 ohms speakers.

I wouldn't recommend this. Speaker outputs are designed to drive 8 ohms of impedance with high current. Line-level audio inputs have a much higher input impedance and require far less current. Using a speaker output to drive a line-level input can cause the voltages at the input to become vary large, almost certainly distorting the sound, and maybe damaging your equipment. Get the step-down transformer described above if your device has no line-level outputs.

This unit is built for output impedance 4-8 Ohm. By using 2 Ohm speakers you are risking to burn unit amplifier; this is not really high end equipment.This unit has RCA output and option to attach an amplifier; that would be better way to go.

You did not mention what you need it for and what speakers you have. For amplifying voice it is more than enough power. If you're a dj and are planning to play music you will need a second nu 3000 connected to a subwoofer. If you have 8 ohm speakers you get sbout 200 watts per channel. For more power you can connect two speakers on each channel making an impedance of 4 ohms.

If they're 8 ohm speakers, this may be a bit under-powered. They have a 3000 model that would be better suited for only a small amount more.

They're supposed to be 4 Ohms even though the back says "4/8 Ohms" but in reality they're less than 4 Ohms - a tad under 3.5 Ohms. unless your amp/reciver can tolerate resistance of 2 Ohms which very few can, don't wire them in parallel with an 8 Ohm speaker. I did and it almost fried my receiver.

Yes, you're right. If your speakers are 8 ohm, then you should connect the red wire to "8" and the black wire to "0".
1496261
you can use 8 ohm speakers,however if you use main and remote speakers they must both be 8 ohms or higher. if u use 2 sets of 8 ohm speakers the amplifier sees it as 4 ohms {speakers are in paralel} anything under 4 ohms will shut the amp down. even playing amp loud it may go in to shutdown when it sees 4 ohms.

I'd stick with the same. Some amplifiers can operate "unsafely" I.e. overheating or crappy sound, if they can't produce the right impedance per whatever ohm each speaker has. I'd start from ground up if you're wanting bigger better sound

I have 8 ohm B&W; cs1 speakers and use 6ohm without an issue. I'm not sure why they didn't design it for 8ohm

Jan, my receiver is a Sony STR-DH520 which is rated as 8 ohm output. I've had no issues connecting this speaker.

On a 4 OHM output amp. You use one 4 Ohm speaker or two 8 OHM speakers. Example: One 8 OHM speaker + One 8 OHM speaker = 4 OHMs.

All speakers can be connected in series but you will have to add the impedance of the speakers that are in series. In this case, 4 ohms + 4 ohms = 12 ohms. The new impedance load for the amplifier would now be 8 ohms. You can easily check this stuff on google.
