Is this amp rated at 10 watts per channel into a 8 OHM load? Also can you increase the wattage running speakers as 4 OHMs?

Unlike Solid State Amplifiers where output power is dependent on Power Supply robustness, Device Ratings (eg Power Transistor) and load impedance in OHMs (ie your speaker impedance), a Vacuum Tube Amp is typically Transformer Coupled (Output Tube &gt; Transformer &gt; Speaker). Many Transistor Amps scrimp on Power Supply or Output Transistor so that power into various loads cannot be easily determined. Were those parts "up to snuff" then power into 4 ohms is double the power into 8 ohms. If there is a spec where the power is not doubled with a 4ohm load vs a 8ohm load, this is a clue that compromises were made and dynamic (real music) playback may be stressed. With a transformer-coupled amplifier (Vacuum Tube or Solid State, although SS is rare after about 1970) the power is always the same into any load the transformer has a winding for. So, typically, 4, 8 and 16 ohm loads would be the same power (eg 10w/4ohm, 10w/8ohm, 10w/16ohm). Although a 16 ohm tap on the transformer is rare today, most can be re-configured to provide a 16 ohm tap. Since there is no power penalty by going to 16ohms, and since damping factor doubles when impedance doubles, a 16 ohm speaker on a tube amp would provide very robust and tight bass response (for example).

Yes, this amp would rate at 10watts per channel into a 8ohm load, but power would be a little lower with the load of 4ohm.

Hi Tyrus, I think the amp is more than sufficient. Please start at low volume otherwise it may damage the speakers. I have used this amp with a couple of speakers between 300W to 500W and it performs well. Thanks and I hope this helps Fernando

Yes. It's a 5 channel amp. 4 speakers 4 ohm @ 75 watts each, then a 5th (your sub) 2 ohm @ 300 watts. It's a great amp.

The 6 Ohm setting on the amp should work okay for your nice 8 Ohm speakers. Higher impedance speakers should dissipate less power and consequently might sound a tiny bit quieter than lower impedance speakers at the same volume setting. But I doubt you will notice any difference.

Hello. The RMS power at 8 ohms is 25 watts, and its peak power would be 33 watts per channel. You will need to wire a speaker at 2 ohms per channel to take advantage of the full output power of this amplifier.

Yes 10 watts per channel, tube power always sounds louder than regular transitor power amps rated at the same power per channel...that's just how tubes are. And the three dimensional properties of sound are more realistic

Dear customer, you're right and I am sorry that I mixed up the model in my last answer. And here's the correct answer: Yes, it's 50w/channel, and totally safe to use with no matter 4ohm or 8ohm speakers.

You may want to series the 2 voice coils to get 8 ohms, then run the amp in bridged mode. The 2 amp channels will see an equivalent of a 4 ohm load each.

Listen to the other answers. They are all correct.I will only add the following,I matched this amp with these bookshelf speakers (rated at 8ohms 120W)Sony SS-B1000 5-1/4-Inch Bookshelf Speakers (Pair)and the sound is tremendous! Love the amp!

if you are lucky you will get about 35-45 watts per channel at 8 ohms....this amp heats up quickly and starts to distort around 75% volume

Short answer = No. Long answer = maybe Speakers are rated in Watts==its a Power measurement. Power = I [current in Amps] x Voltage [of the line out from the Amplifier.] http://www.engineeringtoolbox.com/electrical-formulas-d_455.html The power supply is rated at 24 volts and 5 amps which = about 120 watts to power the unit. The amplifier is not a bridged type amplifier and cannot drive anything less than 8 ohms on one channel. Maximum 50 watts per channel. see --- http://www.daytonaudio.com/media/resources/300-383-dayton-audio-dta-100a-manual-43827.pdf As you wish to put two speakers in Parallel and they are 8 ohms=== then you are lowering the ohm's of the speaker to about 4 ohm's, this is not in the spec for this amplifier. If your speakers are 16 ohm and you put them in parallel then that will be alright === the result of that is 8 ohms, this is how most TV speakers are set up.[ assuming that each is 25 watts.] Remember it is a small amp and to incrementally increase the volume over time to see how it handles it. Else get a different amplifier.

You are too vague in your question. Can't help you out unless you give speaker info how do you have them wired 4 or 8 ohms/rms wattage/peak wattage. I have my amp hooked up in my house to kicker subs 500rms each at 8 ohm, they are plenty loud. just as load if not louder than my 1000watt car amp.

from my understanding your speakers ohms should not be lower than your receiver/amp. This will have your receiver working overtime to power those speakers which may casue overheating. For a 8 ohm receiver the lowest I would go would be 6 ohms; I think 4 ohms is pushing it.

"301: Compatable with amplifiers and receivers rated from 10 to 150 watts per channel. Rated 4-8 ohms" quoted from owners manual. My receiver is 8 ohm.

At 4 ohms it 1200 watts. At 2 ohms its putting out 2600 and at 1 ohm your getting 4000 watts. Its a true 4000 watt amp. I am pushing a 15 inch massive audio comp sub with this amp and it has no problems at all moving it.

It's best if you use speakers that can handle the output of the amplifier. Since the manufacture states 2000 watts, I think that they are telling us the that is the output at 2 ohms. I run a Peavey IPR 1600 at 8 ohms and my amplifier will only put out 300 watts per channel at 8 ohms. My amp will put out 560 watts at 4 ohms . It will produce 1600 watts at 2 ohms, however running a power amplifier at 2 ohms is hard on the amplifier. Its best to run speakers that are 8 ohms and you'll have clean and clear sound as loud as the amplifier will produce at 8 ohms. Less wattage clear sound.
