How do I connect amp to receiver?


Amp?? You want to connect an audio amplifier to another audio amplifier? Well, start by finding your local electronic repair shop's phone number as "speaker level" does not play well with another "speaker level." External devices such as CD, MP3, DVD, etc. output what is called "Line" level which is a fraction of the amount created by speaker level amplifiers. Audio equipment is designed to amplify this line level input to a speaker level that will...well, power speakers. Wikipedia should be able to explain this in more depth.

I have a panasonic SA-HE70 amplifier and all it keeps doing is scrolling OVERLOAD.... why??


hi,.

First of all remove all the speaker connections from the amplifier. After that power the amplifier and check that it gose Over load ( protection ) show or not . if not, then any of the speakers or its wiring have some problem. If so the reconnect the speakers one by one and switch ON the amplifer and check.find out on wchi speaker it shows lover load.


if the amplifer shows overload even after removing the speakers then you have to check the amplifiers hardware.

Also added the procedure how to check the amplifier satge. You should have a good knowledge in electronics to do the following. Also need testing instuments.


AV receivers shows protect mode , when there is a hardware fault in side it. Its a warning that some thing is wrong.
Normally AV receivers show this when any of the output amplifier have some problem. there are five amplifiers in this AV receiver. This problem occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers. To prevent this there is a protection circuit for each channels. One combined output of this protection circuit is connected to the system control. when the any of the output amplifier fails, the protection circuit detects it and switch of the speaker and sent data to the system control. when the system control get this data it will give a warning to the customer through display that PROTECT.
You have to check the amplifier.

For that you need digital multimeter,soledring iron screwdrivers etc

Open the amplifier , then power it on. connect the negative terminal of the multimeter any where in the chase( metal body of the amplifer). then connect the positive terminal to all the output transistors emitter pin one by one . the voltage should be bellow 0.5V. If any of the emitter of the transistor shows voltage more than 0.5V., then that amplifier stage is faulty. Remove the transistors and check it. if it is shot then replace with a new one.
after replacing the transistors do not power up the amplifier directly from the main. You have to put a bulb of 60 watts in serial.
You can do this easily remove the mains fuse. put the bulb in a holder. now you have to wire from the holder. connect one of it to the one end of the fuse holder and the other wire to the other end of the fuse holder. Why using a bulb is, if there is any further problem in the amplifier stage on which the transistors replaced, there is a possibility of the new transistor get damage. if we use a bulb in serial with its mains supply ,when any overload in the amplifier occur the bulb will drop the current, by lighting itself.
After connecting the bulb in serious power on the amplifier. watch the bulb. It should light for one or two second and go dim . if so check the display, is there is protect mode is on or not . if not and come back to normal operation ,then remove the power , remove the bulb insert fuse and check
connect the power and check.
If the bulb shows bright light then there is some component also faulty in the same amplifier. after removing the power you have to check again the amplifier stage of which the transistor is replaced, for any other faulty components

OK

"im no proffetional at this". Really?

If you looked at the manuals for either product you would NEVER find a recommendation to use one amplifier's speaker input to drive the LINE LEVEL (very small) input on another amplifier. Speaker outputs are for driving speakers or amplifiers designed to accept speaker-level input (like some self-powered subwoofers). In no case is the power of the originating amplifer BOOSTING the power of the driven one.

You should do some reading on how amplifiers work before you blow something up and come asking for advice on how to resolve it.

Pioneer vsx 515 overload and shuts down what can i do to fix this problem.


hi,
First of all remove all the speaker connections from the amplifier. After that power the amplifier and check the overload (protect) show or not . if not, then any of the speaker is damaged or you have to check the impedence of your receiver and speakers. It will be written on the rear side of both receiver and speakers in ohms. PIONEER recommend to connect 8 ohms speakers in to this AV receiver. If you are using 6 ohms speakers you have to do some setting in the AV receiver.For that do the following

1. With the receiver in standby, press STANDBY/ON while holding down the SPEAKER IMPEDANCE button.( Each time you do this, you switch between the impedance settings: )


SP 6 OHM - Use this setting if your speakers are rated at 6 Ohms

SP 8 OHM - Use this setting if your speakers are rated at 8 Ohms or more


You are not able to connect speakers with impedence bellow 6 Ohms with this receiver. Becuse the AV receivers impedence range is 6 - 16 Ohms.
If then also it shows protect you have to check the amplifiers hardware.

AV receivers shows protect mode , when there is a hardware fault in side it. Its a warning that some thing is wrong.
Normally AV receivers show this when any of the output amplifier get some problem. there are six amplifiers in this AV receiver. May occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers.

Our receiver automatically shuts down, showing 'protect' in the display, when volume is turned up to -30 db. How can we stop/reset this? We really appreciate your answer.


hi,
First of all remove all the speaker connections from the amplifier. After that power the amplifier and check the protect show or not . if not, then any of the speaker is damaged. If its goes to protection mode when you incrase the volume then check the impedance of your speakers it should be 4ohms or above . Test with some other speakers if available.

Amplifiers gose protect mode , when there is a hardware fault in side it. Its a warning that some thing is wrong.
Normally amplifiers show this when any of the output amplifier have some problem. there are two amplifiers stage left and right . May occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers. To prevent this there is a protection circuit for each channels. One combined output of this protection circuit is connected to the system control. when the any of the output amplifier fails, the protection circuit detects it and switch of the speaker and sent data to the system control. when the system control get this data it will give a warning to the customer through display that PROTECT.

Then connect the positive terminal to all the output transistors emitter pin one by one . The voltage should be bellow 0.5V. If any of the emitter of the transistor shows voltage more than +/- 0.5V., then that amplifier stage is faulty. Remove the transistors and check it. if it is shot then replace with a new one.
After replacing the transistors do not power up the amplifier directly from the main. You have to put a bulb of 60 watts in serial.
You can do this easily remove the mains fuse. Put the bulb in a holder. Now you have two wire from the holder. connect one of it to the one end of the fuse holder and the other wire to the other end of the fuse holder.

How to connect my phillip cd player to speakers


It depends on whether the player has an Audio output because only then you will be able to connect the output to a speaker .
However if there is only an audio output - composite signal- then you will need a power amplifier to connect the speakers while the CD player is coupled to the power amplifier.

What's the proper way to wire 2 sets of speakers,


the center speaker is easy just wire it to the center main posts (connections are near the middle of the box) (just match up the colours)

and the powered speakers do they have their own amplifier or are they just speakers

if they have their own amplifiers then use the pre out connections near the top of the box

if they are just speakers then
wire them to the front main speaker connections near the right of the box

Kenwood Receiver VR 806 turning off


Sounds like the music amplifier is different to the tuner audio amp. The music amplifier is now looking at an unbalanced impedance which is less than it should be. Therefore the output chip of the music amp has more current through it than it wants so it gets hot and shuts down.Put a four ohm wirewound resistor ( from Radio Shack ) in series with each surround speaker to reduce the current flow through the amplifier output.

Just bought a denon, and wharfdale 9.1 speakers with no rca cables, what rca cables do i need?


What model speakers?

Didn't these things come with manuals?

Speaker connections from the Denon are typically through speaker cables (glorified lamp cord).

The Denon is not capable of driving the sub directly. The powered (?) subwoofer in your setup would presumably require an RCA cable (whatever length reaches) to feed its amplifier a bass signal from the Denon's Subwoofer Out.

I have to connect 11 speakers in a restaurant to a 2 zone amplifier that is 500 watts per Chanel. How do I choose the power of the speakers and Which way do I wire them --- in parallel?


what size speakers and what watts, how many channels on the amp, you could do it in either way
There are two ways to wire electrical components. In parallel or in series. Both are important to understand, especially when properly hooking up speakers to amplifiers.
Parallel wiring is connecting components to a source so that they share the same voltage. To put that in a useful way, it would be connecting all of the speaker positive terminals to the positive terminal of the amplifier and connecting all of the speaker negative terminals to the negative terminal of the amplifier.
Series wiring is connecting components to a source so that they share the same current. To put that in a useful way, it would be connecting the amplifier's positive terminal to the positive terminal of the first speaker and then connecting the negative terminal of the first speaker to the positive terminal of the second speaker and so on. The final speaker in the chain will have it's negative terminal connected to the negative terminal of the amplifier. Hope it Works
