Question about Pyramid Audio Players & Recorders

Open Question

I am using a pyramind zpa 100 to power a home system with 8 (6ohm) speakers and ohm matching volume controls (hubbell ?) I plan on using the amp for basically background music but I would like to get the most out of this amp that I can. That being said on the back of the amp to plug the speakers in for the "bridge mode" it shows connecting bthe speaker wires to both positive termials ? There is also a switch for stereo & bridge, I assume bridge and mono are the same ? I only have the audio source plugged into channel A and volume control A only adjusts the volume channel B does nothing ? So basically can anyone tell me how to connect the source and speakers for the best performance. Thank You Don

I wouldn't hook anything up except what Yamaha recommends to the speaker output terminals. That's pretty much asking for trouble!

SOURCE: Thumping speakers - no power light is on - wired correctly

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

SOURCE: Amp Power light will not go on. Protection light is lit- Thump sound in speakers

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Let me know if you have any other questions.

SOURCE: Rotel PReamp, Can I directly Connect my powered speakers to the output

Hi,

Based on your post, the pre-amp is doing its job. What might be the mismatch would be the powered speaker system plugged into the output of the Rotel. Depending on what the "powered speaker system" is, it might be that it is a low impedance such as those used in computers whereas the Rotel requires high impedance to be connected to its output. What could be tried is to connect a regular amp or receiver to the Rotel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

SOURCE: Dialog track not playing for a 5.1 DVD

Unfortunately without "surround" processing, the center speaker will not work at all. It sounds like there is a problem with the center channel amp which is part of the receiver. This should be a single amp IC attached to the heatsink. There should be a "test" moe that will send white noise to each speaker in sequence. Try that. If that results in no sound to the center, it pretty much concludes that the center amp needs to be repaired. The part cost for this should be around $25.

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.

4 ohm and 8 ohm speakers


You can plug in higher ohm speakers , the higher the ohm the higher the resistance is, it is a danger when you plug lower ohm speakers into a higer ohm Amp , at a high volume that will cause them to blow , the center speaker would be fine to use a higer ohm speaker , your best choice is to buy a Active Subwoofer, which means the sub has it's own power supply , and u can blast the thing as much as u like , thn u can turn the bass down on all the other speaker's so u can play it louder , and have the sub turned up has high as u like , this is the best way to get great sound with high volume , buy a Active sub woofer , any active subwoofer is ok , a active sub woofer has its own volume and inputs on the speaker ,

Will the E-715 work at 4 ohms


Hello,
They will work at 4 ohm, but you won't get near as much volume out of them as you would if you used an 8 ohm amp. The E-715 speakers are rated for 8ohms. You could damage your amp running speakers that are not matched to the same ohm rating, however it is safer to run a low ohm amp to higher ohm speakers then it is to go from low ohm speakers to a high ohm amp. Your speakers will perform how they were intended if you match the ohm rating, so try to do that at if at all possible.

Receiver shuts off at higher volumes


The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.

The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.

If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.

Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.

I have a 50x2 amp that is bridged 100 into a 4 ohm load. can i run this to a 6x9 3way speaker rated 100rms 4 ohm


Yes, you can. There's the impedance match between amp and speaker (4ohm to 4ohm).
The only issue I would say is that if the amp is putting out 100 watts RMS, then you wouldn't want to drive the speaker to the max, because it's rated at 100 watts RMS max, and at louder volume, it will start to distort and possibly blow from fatigue. Other than that issue, it should work fine.

two 8 ohm speakers in parallel is 4 ohms.
if series 16 ohms.a high resistance will just produce less power.
too low a number can activate the speaker protect,or blow the amp.
radio shack sell wall mounted speaker controls,but 5 watt max.
the best thing is to run 2 amplifiers.one for in ,2 for out
speaker a and b on the amp parallel the speakers.
if you run 2 sets of 4ohm speakers,the amplifier load will be 2 ohms,and overheat the amp.4 8 ohm speakers,gives a 4 ohm load

The power keeps shutting off when I turn the volume up.


check the nomimal ohms or impendance of the speakers if it matches the amp capability. Your amp manual should specify the compatibility of what speakers ideal to whether it's 4 to 8 ohms.

Fried electronics in KLH ASW10-120B subwoofer


It is a 4 ohm nominal impedance woofer. If you put a new woofer in, it will last maybe half an hour and then fry/melt. The problem is the amp, not the woofer. Throw the amp out and use the box as a passive sub. Get a 100 hz sub crossover.

you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
