Question about Audio & Video Receivers

Open Question

My Marshall G80R CD Amp 80W Amplifier is experiencng some difficulty. When I am playing it at concert volume, using a Zoom 1010 effects pedal, it keeps massively reducing volume and losing effect. Each time I seem to do a different thing and it goes back to its original sound. I am playing it through a fender squire stratocaster.

SOURCE: Losing volume on channels

I am afraid not. That crackling is a component in one of the solid state amp circuits starting to fail. These are all soldered into the printed circuit board. This could be a difficult repair to find an intermittant component. Depending on how old the unit is and how much it cost will factor in on if you have it repaired or not. Rule of thumb is that if the unit is two to three years old and cost less the 200 to 300 bucks you should not invest more then 100 to 150 bucks into it. Good Luck

Check the 'front mix' switch on the back, set it in off; main level on max.

Hi there,
The general fault come up with the AV recievers is:
My A|V receiver says, "OVERLOAD" and shuts off, what should I do?

Poor wiring connections, bad wires or a bad speaker may cause this. As you increase the volume, you will increase the amount of current you are drawing from the receiver. To troubleshoot this issue, try the following:

1. Disconnect each speaker wire connection. Inspect for any frayed or damaged wiring and replace it.
2. Check the impedance of the speakers; make sure they are properly rated for your stereo. In most cases, they need to be 8 ohms. Only a few Pioneer receivers will support lower impedance.
3. If the problem still continues, try these steps:
1. Turn the receiver off.
2. Remove one speaker.
3. Turn the receiver on.
4. Increase the volume.

If the receiver overloads, repeat steps 1-4 (selecting a different speaker each time). If you disconnect a certain speaker and the receiver no longer overloads, have this speaker checked at a service center. It could have a bad speaker component, like a tweeter, sub-woofer, or even a bad crossover.


Regards
Ellin

There is a disparity in the impedance of the speakers and the outputs of the receiver - the speakers are too weak and they act as a short , damaging the amplifiers , hence the Protect status being engaged.
Trying to run the receiver with a wrong set of speakers has probably damaged it. Get a correct one and try the setup only with it, if you're lucky it was just the safety system cutting the output.

How to connect a turntable connected to a yamaha a450 stereo amplifier...can I attache the a450 to the htr-6130 ?


If the turntable is newer kind you can connect it in any Stereo input like CD, VCR , etc.

If the turntable is older model you can only connect it to PHONO input (if amp has one) and make sure earthing cable is connected on Amp

Remember input is only stereo (unless your model has digital input) and select sound effect eg Pro Logic for enhanced sound,

Hello i need help please..... I have a Technics SU-Z550 and SH-8055 Graphic Equalizer My amp has lost power... lots.! its working one channel louder than the other but the one which is louder still has...


If the same channel is dead on the EQ as is dead on the amp there may be a correlation.

Let's break this into its two parts.

1) SU-Z550: You don't say WHAT source(s) you tried to use on the CD/AUX, TUner and PHONO inputs. The external device itself could be the source of the low volume. Try swapping the Left and Right cables to see if it follows the source channel or stays with the amplifier channel.

Check the controls on the amp to make sure you understand each one's effect on the sound.

"PHONO" is literal and exclusively FOR A TURNTABLE - NOTHING ELSE - EVER.

2) SH-8055: Equalizers don't 'boost' sound, they modify its levels at various frequencies. To do that they should be connected into a Tape loop on your amp. OUTs go to IN's. Then you select the Tape Loop on the amp and that inserts the EQ into the signal path of whatever source you're listening to. It's actions are BEFORE any other amplifier controls such as volume, tone and balance. The EQ itself also has a Tape Loop to replace the one it occupies. Make sure it is not enabled unless you have a Tape Deck on it to use. Choose "SOURCE". The blue LED display is to show you frequencies are present in the program material.

Set all of its lighted band controls at midpoint prior to declaring it defective. EQ is like any spice - a little is good, a lot ruins the recipe.

I have a technics ST-X933L tuner as part of a separates system and the volume on the amplifier has to be turned up to almost full volume to be heard. All other inputs are playing at the expected volume for...


You can answer the question by jacking the tuner's outputs into any other Line Level input on your amp/receiver. If it's still low, the tuner is at fault.

BTW: NEVER use full volume as a test unless you intend to blow up your speakers.

I have a fisher ca-9335 integrated stereo amplifier thats hooked up to sanyo tp 1010 turn table and plays out of yamaha ns-70t speakers. a simple jvc cd player is also hooked up to the speakers but not to...


Something doesn't add up. You mention two connections to the speakers - CA-9335 and a "simple jvc cd player". Is that true? If so, you might want to UNconnect the CD from the speakers and run it into the receiver where it belongs. An amp isn't designed to share the load with another live device; or even have electrical contact with anything BUT speakers.


Did you actually find documentation that supports this hook-up? Or just winging it?

Hello. I have a question. My amplifier has a dat/dcc input. Is this input for a digital compact cassette deck only? Can I use it as aux, i.e. can I connect CD player, dvd player or tuner to this...


You could try plugging into this socket if it is a phono socket. If it is a little square black hole its probably a digital only sock and it wom't be compatable with your CD player, etc. If the sockets and plugs match turn the volume to ZERO - turn off the amp, plug in the CD, etc. and with a disc in it press play. Turn the volume up VERY slightly and listen for any sound. Try the different input buttons to make certain the circuit is complete. Keep the volume low as you don't want to damage the speakers. Good Luck

Number of inputs


Each CD Player has audio out put amplifier circuit and this output amp remains Mute until it receive signal to out it. While using Y-Connector, when you try to listen one player sound, other goes to Mute as its in Stop position and caused to minimize the out put of other player which is being played. That's why you listen good sound if just one is connected. If you want to connect both players at one amplifier, you need at-least 2 inputs in amplifier and since your Fisher amp has not 2 inputs, so I suggest to buy another amp equipped with 2 or more inputs. Hope this info will help you.
