Question about Audio Players & Recorders

1 Answer

I have an old stereo amplifier (purchased about 25 years ago). The left sound channel is no longer sending a signal to the speaker. I reversed the speaker connections which confirmed that the problem was the amplifier and not the speaker. Is this a fixable problem, can I find a repair shop to do this, or should I replace my amplifier.

Try checking the speaker fuses inside the amp (a fairly inexpensive fix).

Stereo only playbacks in mono. it used to play stereo

Stereo is actually two identical amplifiers which when the left and right of a stereo signal is fed into the respective inputs will reproduce the stereo sound through the left and right speakers.
Mostly there is a mono/stereo switch so if only a mono signal is available it is reproduced through both speakers.

You don't make it clear whether the playback is in mono or half a stereo?

If playback is in mono it will emerge from both speakers but the directional element will be absent. If the playback is in half a stereo the sound will emerge from one speaker only or mostly one speaker.

Most common problem is the failure of one of the amplifiers which could be electronic or the failure of any of the various switching usually used in such things.
The amplifiers can be tested by injecting a signal into each amplifier input and will be found satisfactory if the sound emerges from each speaker in turn at a similar volume.

No volume on all left side speakers

Determining the Cause of the Problem Let's assume our system has a head unit, a crossover, a two channel amplifier and two door speakers with only the right speaker working (the left speaker is not working). If the door speakers are behind the door panels then we want to make sure the speaker is the problem before removing the panel. We'll work backwards starting with the amplifier and ending at the head unit. Testing for a Speaker Problem With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output (which we know works). Turn on the stereo system and make sure the balance is set to the middle position.If the speaker still doesn't work then the problem is somewhere between the amplifier and the speaker Testing for an Amplifier Problem Now we'll need to see if the amplifier channel is bad. Put the left speaker back on the left amplifier channel and the right speaker on the right amplifier channel. This returns the speaker wiring to its original configuration. Again, with the vehicle and stereo off unplug the RCA cables from the amplifier's input and switch them so the left cable is in the right input and vice versa. Turn on the stereo system. Testing for an RCA Cable Problem For any intermediate components between the amplifier and the head unit follow these steps for each one. We only have a crossover so we'll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component's output. Now plug the working channel's RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.
If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover. esting for a Crossover or Equalizer Problem At the input of the intermediate component (in our case the crossover) flip the RCA cables around (left to right input and vice versa). Turn on the stereo system.
If the right channel continues to work and the left channel continues to not work then you know the problem is in the intermediate component. Replace or repair this component.
If the problem is now in the right speaker and the left speaker works then the problem lies before the crossover. Turn off the stereo system and return the RCA cables to their normal places.
Testing for a Head Unit or RCA Cable Problem Pull out the head unit from the dash so you can access the RCA cables. Unplug both RCA cables from the head unit. Do not disconnect any other wiring. Plug the right RCA cable into the left channel of the head unit. Turn on the stereo system.

Very week sound

Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.

My mac is hooked up to my receiver via analog cables. I have never had any problems, but now for some reason when in stereo mode I only get sound out of the right speaker. I'm only looking for 2.1 sound...

The most common problem at cases like yours is the jack to RCA cable that connects your mac to the Denon amplifier. This is a cable like this:
Usually there is an internal cut at one of the ends. Check this cable and in case of a problem replace it; it's very cheap. A quick test is to reverse the RCA jacks at the amplifier's side; if you get sound from the left speaker you can be sure that one channel of the cable is faulty. At the "virtual mode" your system is trying to create a stereo image so it's logical to have "pseudo" audio from the left speaker.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

I need speakers for my Onkyo A-911M integrated amp

A+B speakers = 4 channels 2 right 2 left

100 watts/4 = 25 watts per channel

RMS watts / channel = 25 x .707 = 18 watts/channel which is your average consumer stereo system

I would use 8 or 16 ohm speakers (not 4 ohm) -- almost any set of stereo speakers will "work" -- these will be 8 ohm and about 5 watt minimum / 40 watt max thereabouts

I want to add more speaker at my paspor fender 500

Run out of the stereo output jacks into a separate amplifier and speakers. The amplifier send jack only sends signal from the particular channel it is part of. In other words to get all the signals from all the channels you would need another mixer, amp and speakers. It is easier to use the stereo out which will give you all the signals. If you only use left out or right out make note of where your panpot is set for each channel.

Right channel won't play on stereo amplifier

In old stereos the first things I look at are output transistors, solder joints and electrolytic capacitors. If you know how to solder, bad solder joints are pretty obvious. If you need a tutorial on how to spot bad solder joints, look here.

As for bad caps, look here. The info is aimed at computer motherboards but still helpful.

Only sound from Direct and Stereo settings on Denon AVR 788

Other listening modes (dolby, dts, neo6) are decoded from digital signals.

Direct will relay your only your discrete analog inputs - so if you want to use your AVR as an amplifier for those channels, you'll need to supply an input signal in a different manner.

check volume balance between right and left-then change inter connection between sound source and amplifier with new cabel(i prefer gold plated type connectors)(see radio shack).
after that if the problem excit your fault in output transistors or output stereo ic depend on circuit design.
