SOURCE: Behringer ep2500 amplifier

Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...

If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.

If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....

SOURCE: 6 ohm speakers - 8 ohm amp

This is a tough one due to the info at hand, but I'll take a stab at it.
I'll assume that your amp is not a tube-type amp. I'll also assume it is a relatively recent "solid state" design. If those assumptions are correct, connecting a 6 ohm load to an 8 ohm amp should not cause significant overheating or amplifier instability.

SOURCE: Yamaha P4500 Power Amplifier 2-Channel Bridge mode

im from Yamaha service before and i know this model can handle as low as 2ohms per channel. I have to check on my manuals though if bridged. i dont see any reason why it cant. and it has a bridge option input stage... let me get back to you again in the days to come.

or email me redrivera0314@tyahoo.com

i have a service manual to check on this. got to dig on my closets..

SOURCE: 3 8 ohm speakers 1 stereo amp 2channel a 1 channel b will this do dammage

If you only have 3 (8 Ohm) Speakers and want to hook them all up, you will need to balance the impedance of the sides or you will be too loud on one side and not loud enough on the other. This will cause your amp to work harder on one side. (Not Good)
I did not see the speaker A and B in the instruction manual.

Because of that, I will state the following.
I would not recommend that you hook up anything that is unbalanced. I would use just a pair in two channel mode (This would give you an 8 Ohm load on each output). The manufacture recommends a 4 Ohm load for the best output of this amp. But the most important thing to remember is that your speakers must be able to handle this much power or the speakers will be permanently damaged.
This amp has Protection to cover: Full short circuits, Open Circuits, Thermal and HF protection, and stable into reactive or mismatched loads.

You could hook up all three speakers and the amp will work, but, I would not recommend that type of hook-up.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

SOURCE: I have a s1500 samson amp I keep blowing speakers,

Turn the volume down? Feed it cleaner source material?

http://s3.amazonaws.com/samsontech/related_docs/s1500_s2000_manual.pdf

You don't say under what conditions you're blowing them or if any of the informative indicators are warning you of impending doom. The Samson is capable of cooking just about any home speaker.


The following conditions will cause the Protection LED to go on:


Initial power-up: For approximately five seconds after initial power-up, the

protection circuitry is activated and the speaker output is muted. If everything is

operating normally, you will hear an audible click at the conclusion of this brief

period, as the protection circuitry is deactivated and the S1500 / S2000 begins

delivering signal to connected speakers (at which point you'll hear a click). It is

normal for the Protection LED to fade gradually after the amplifier is powered off.

Overheating: A temperature sensing device in the S1500 / S2000 will cause

the protection circuitry to be activated (and the Protection LED to go on)

whenever the operating temperature of the unit rises above a safe level. To

guard against this problem, make sure the S1500 / S2000 receives adequate

ventilation on all sides and that both the front and rear panels are unobstructed.

Severe overcurrent conditions: This occurs whenever the signal being input to

the S1500 / S2000 rises to a level above 20% THD (Total Harmonic Distortion).

Shorted speaker cables: This will occur if, due to faulty wiring, the hot and

ground signals being output by the S1500 / S2000 short one another.

Output impedance drops below 2 ohms: This can occur if the S1500 / S2000

is connected to inappropriate speaker systems (see the "Setting Up and Using

Your S1500 / S2000" section on page 5 in this manual for more information).

DC voltage detected at speaker output: The most likely cause of this is an

internal failure.

In general, any time the Protection LED lights up (other than during the

approximately five seconds following initial power-up), there is reason to be

concerned. If this occurs, turn the S1500 / S2000 off immediately and carefully

check all wiring and external devices in order to locate and correct the condition

that caused the LED to light up in the first place.

For further assistance, contact your local Samson dealer. If purchased in the

United States, you can call Samson Technical Support (1-800-372-6766)
between 9 AM and 5 PM EST.

Can I connect two 4 ohm speakers to make it play on single 8 ohm speaker channel on a receiver


Yes, two 4 ohm speakers wired in series will present an 8 ohm load, though even with matched speakers they are likely to produce different volume levels.

It is probable the receiver will be quite happy using a single 4 ohm speaker if only modest volume levels are used. Many popular hi-fi amps quote power outputs for both 4 and 8 ohm indicating either could be used.

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.

I have Behringer 1c monitor speakers. My amplifier is Yamaha 8 0hm, 75 watts per channel. How do I connect the 4 ohm speakers to 8 ohm apmlifier.


This is a problem I have had as well. Know that Yamaha and other manufacturers that give an 8 ohm minimum spec DO NOT reccomend hooking 4 ohm speakers up to their amplifiers. That being said, I have had no problems with the Behringer 1C on Onkyo, Sony and JVC amps. You *must* be careful to regulate your listening volume, and be aware that the distortion the amp produces into a 4 ohm load is much higher than with 8 ohms. You also take the risk of cooking your output transistors.
It is up to you to decide if the risk, the neccessary self imposed volume limiting and the added distortion are worth it.

Just got two AR 312 HO speakers from my brother. I have a Yamaha HTR 6250. The speakers have (2) sets of cable hook up. One I assume is for built in sub woofers? Do I hook one normal and one to the sub...


do not use those speakers with that amp, those are 4 ohm speakers, which could damage your 8 ohm yamaha amp. you will have to get a 4 ohm capable amp to run the highs, and another 4 ohm amp to run the subs.

car amplifiers are currently 4 ohm, or even 2/1 ohm stable, but few, if any modern receivers can run at anything lower than 8 ohms without a danger of overheating. you may have to get a vintage amp(s), like a 1970's marantz receiver, or a 1980's to early 1990's kenwood power amp, because 4 ohm home amps are pretty scarce nowadays.

whatever amp(s)( you get, verify that they are DEFINITELY 4 ohm stable.

How do you switch from 8 ohms to 4 ohms on a 3500 yamaha amp


Switch what? It accepts 4 ohm speakers for stereo mode just fine.

Run 4 ohm on yami 1600


The manual says...

"If you are to use 6 ohm speakers, be sure to set the "SP IMP" to "6 ohm Min" before using this unit (see page 30). 4 ohm speakers can be used as the front speakers (see page 118)." ... which basically says the same thing in a table.

Set it for 6 ohms and try ity out. If it exhibits any problems like the amp cutting off you might want to lower the volume or analyze it to see if the 4 ohm guys are the problem.

BTW: That spec is just a nominal value. At various frequencies every speaker's impedance changes. The proof is in the pudding. The Yami won't self destruct unless you crank it to the stops and ignore the audible warnings of stress.

Can you run 200watt 6ohm speakers on the RX-V490


Hi I have just read the specs on about your Yamaha system and you cant run 6 ohm speakers to your amp. You have to impedance match the speakers and the amp otherwise the speakers will "blow". So you need some 8 ohm speakers, the wattage of the speakers doesn't particularly matter as long as they are not too weak or too powerful becasue the amp will drive the speakers no matter what but if the speakers are of a low wattage then the amp could blow the speakers if it is turned up too loud. The specs of your amp are given in the link below.

Help me...


If you had 4 single voice coil speakers you can create either of those 2 ohm or 4 ohm setups. If you run 2 of them in parallel you will get the 4 ohms. If you run 4 of them in parallel you will get the 2 ohms. In parallel I mean that you connect the positives together and run them to the positive on the amp and the connect the negatives together and run them to the negative on the amp. Let me know if you need more help. Good Luck.
