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.

How to hook speakers up to a realistic mpa-40


The MPA-40 is a mono public address amp. So it has one speaker output. You select the appropriate socket to suite the speaker type. The 4/8/16 Ohm outs are for various tpyes of Hi-Fi speaker. The 70 Volt is used for muzak in shopping centres, restaurants, and waiting rooms.

If you have a pair of 8 ohm Hi-Fi speakers, you can diasy chain the connections and then use the Com and the 16 Ohm connection.

Daisy chain means you take the wires from a pair of speakers. Connect together the wires going to red on one speaker and black on the other. This now leaves you with two wires going to the other red and black terminals on the speakers, but the ends in your hand are not connected to anything yet. Plug the black in to COM. Plug the red in to 16 Ohm.

The sound from the speakers won't be stereo. It will be mono because that's all the amp outputs. But both speakers will work so long as they're functioning units.

If you have two 4 Ohm home theater speakers then you can do the same trick. 4 + 4 makes an 8 Ohm load. Connect the red to the 8 Ohm output.

Don't be tempted to try to connect to multiple terminals. The amp isn't powerful enough to to run more that one speaker chain.

Hope this helps

How many speakers can you connect to a tannoy s10


The question doesn't really make sense because a Tannoy S10 is a speaker. You can daisy chain as many speakers as you want. That's not the issue though. It's what load the amp sees that's the problem.

Most Hi-Fi speakers are a nominal (that means average) 6~8 Ohm load. However, the Impedance varies with frequency and phase. So at certain frequencies the amp will see a much higher load; maybe as much as 30 Ohms. At other points the load will drop to 3 or 4 ohms. The reason why your amp doesn't fry itself is that music contains a wide range of frequencies, so the load is made up of lots of different slices of impedance all summed together.

If you start to add extra speakers on to an amp then one of two things will happen. Either they'll be wired in series; in which case the Ohms load will increase by the addition of the speaker impedances e.g. 8 Ohm + 8 Ohm = 16 Ohms pre channel. Or the impedance will be reduced because the speakers are wired in parallel (1/8 + 1/8)inverse = 4 Ohms.

16 Ohms is about on the limit of what a very good Hi-Fi amp could drive. But the volume will be reduced and the amp will go into distortion much earlier.

4 Ohms is a much bigger problem. The impedance swings will dip dangerously low to the point where the amp sees the speaker load as a short across the terminals. At that point the amp will dump a whole load of current into the speakers, thus frying the voice coils and burning itself out. That ends with a small puff of smoke and a very large repair bill.

If you want a system louder then you have to add more amps and more speakers. Simply piling speakers on to an existing amp won't do it. You're spreading the amplifier power more thinly because of the extra load, so each speaker ends up being quieter.

I have the TOA 906MK2 and do not know how to hook up 2 JBL 8 ohm speakers to it. I am unsure about the connections int he back (25v or 70v). How do I make this connection?


you should not connect any regular spks to the 25/70 line o/ps use the direct 8ohms connections if they exist, this amp is normally used for what used to be called 100V line and produces real AC volts on the 25/70 outputs this will damage any normal non transfomer type speaker.

Hope this helps
Thanks for using FixYa

CAN i purchase speakers for sanyo da 1000


Unless you want the same speakers for cosmetic reasons, you can get a pair of speakers from any Hi-Fi outlet. All you need to know is the max power output of the amp in watts for each channel, and the ohms it puts out. For instance if it says 8ohm 15 watts. You can get a speaker of 8ohms or higher, but not lower. And any speaker above 15 watts.
Actually you can get better quality sound from the speakers as the speakers they often put with these systems are rubbish in terms of hi-fi quality!
PS
Just had a look around the net and the output power in watts is just 8. Couldn't find the ohm rating but most are 8ohm. So any speaker higher than 8 watts will do the job.

How do i connect 4ohm speakers to my 8ohm jvc receiver


You must connect two sets of speakers to do this.
You must connect them in series.
Meaning, you connect the positive of one to the positive (red) on that reciever. Then you connect the negetive of that speaker to the positive of another four ohm speaker, then run the negetive of that speaker to the negetive on the reciever. Just like if you were connecting batteries together.

Remember never to connect multiple speakers in paralell. (positive to positive and negetive to negetive) as this would make four ohm speakers into a two ohm configuration.

You can use speakers with higher ohm ratings in this setup. For instance, if you connect an eight ohm speaker in series with a four ohm this would give you 12 ohms. Which is also acceptable.

IF THE WOOFERS HAVE 2 VOC.COIL EACH HOW DO YOU CONNECT WITH THE AMP THAT HAS ONE CHANNEL WITH TWO + AND TWO -.


it depends on the load you want to present to the amp. un 12, 2009 - If woofers are 2 coil, then you definately need to know the impedance of the coils (are they dual 2 ohm, or dual 4 ohm?). For dual 4 ohm speakers you will only be able to acheive a summed load of 1 or 4 ohms. If your amp can handle 1 ohm, then connect this way: 1 ohm: Connect both the positives and the negatives together on each speaker. This puts them in paralell which will result in a 2 ohm load per speaker. After you connect the two 2 ohm loads to the amp, it will see 1 ohm as it's load. If your amp can handle this, this is usually the lowest configuration capable by consumer stuff, (if you are not doing competition or some crazy thing), and few amps are rated for 1 ohm so it's not really recommended and may heat up or blow your amp. 4 ohm: Connect one negative to one positive terminal on one speaker. Drive the other open terminals with the amp. This places coils in series and results in an 8 ohm load per speaker. After connecting both speakers to the amp, the amp will see a 4 ohm load. In both cases, the rates power of the amp (at that load) will be divided equally between the speakers. Jun 12, 2009 - For dual 2 ohm speakers, the only loads you can achieve are .5 ohm (1/2 ohm), and 2 ohm. The connections are the same as above, and this results in: ...If coils for each speaker are wired in paralell, the results are 1 ohm per speaker, and after connection, the amp sees 1/2 an ohm. (.5 ohm) ...If coils are wired in series, the result is 4 ohms per speaker, and the amp will see 2 ohms after both are connected.

Need to know the OHLMS rating for speakers


Hello! The impendance of the "speakers" does not be "minor" of the "system" . If your system is
3 Ohms, yours speakers must be 3 Omhs too, or 4, 6, 8... Use serial or paralel conectios. Ex.: 3 Ohms +3 Ohms in series = 6 Ohms ---- 3 Ohms +3 Ohms in paralel = 1,5 Ohms.

Sorry about my bad english, I'm just speak in portuguese.

Connection of speakers


you must be aware of the output impedance of your amp
you connect speakers in parallel and series in combination. eg- if the output impedance is 4 ohms,
connect two 8 ohm speakers in parallel
0r four 4ohm speakers as follows :- two pairs of speakers in paralell [+to+, -to-] then connect the +of one set to the - of the second set and the other two wires to the output.

Speakers


If I understand you right, you have 7 speakers on 7 different channels.
When you have just 1 speaker connected it sounds fine, but any time you add more speakers it shuts down, or does it sound fine until you have all 7 of the speakers connected.

Bare with me, and we will figure this out. It is a very diificult job trying to troubleshoot something that is not in front of you.

After this post, it will be about an hour or so before you will hear from me again, I will be on my way home from work.

Is this a 5.1 surround system or is it listed as 7.1?

Do have have any speaker outputs with more than 1 speaker connected to it.

If this is a 5.1 system, do you have speakers connected to the "A and "B" speaker jacks?

What kind of speakers are they, and do they say on the back where you connect the speaker wire what ohm rating they are. Most speakers for your home are 8 ohms.

in case you were wondering what a 5.1 and a 7.1 system is:

the 5.1 system has front right, front left, center, rear right, rear left and the .1 is for the sub-woofer that is normally a RCA jack output on the back of the receiver

The 7.1 has all those same speaker outputs plus it has a surround back with right and left channel.

I will get back to you in about an hour or so.
