Question about Carver PM950 Amplifier

1 Answer

Carver pm1400 quits working on right channel from time to time.

It sounds good for 15 or 20 minutes then the right channel stops working. after a few minutes it will kick back on. a couple times ive tapped on the front and top snd either it was a coinsadence that it kicked on by itself about the time i tapperd on it or the tapping did something. can anyone give me a idea what to check. the only ppl in my area that work on things like this alway end up wanting more to repair the item you take them than its worth. thanks

Hi...

Make sure your input cables are good and that your output cables are FIRMLY connected.

Does the problem change when you rotate either volume knob?

If this helps please rate my help

I don't have any instructions so i don't know how to hook up my speakers and the t.v for surround sound i have a carver avr 100


You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.

Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.

Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.

On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.

You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.

Connect the center channel speaker to the center channel speaker output on your amp.

If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.

Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.

I have a carver M 1.5 amp rt. channel is out.


Carver designs in general are not easy to repair. I would recommend that you send this unit into a Carver authorized service center. The likely problem is the output transistors, but the driver circuits and predrivers are not simple designs and if there is a problem there, it could effect the outputs. Tracing this will require equipment and schematics that I don't believe are available on the net.

Best amps for bose 901


You need an amplifier with at least 200 wpc to get the most out of your BOSE. Look into getting a NAD, ADCOM or CARVER amplifier. I prefer CARVER myself. I am running a CARVER M-500T(251 wpc) on my 901's and they sound incredible.

Nad C320 right channel stops working then comes back again


This sounds like the "pre-amp" section is cutting out or there is some interruption in the signal path. A few things to try:

1) With the unit off, try "working" the volume,balance and tone controls. This means, turn them up and down a number of times to clear any debris that may be in the controls themselves.

2) Work the input selector switch the same way if it is a rotary switch.

3) Try turning on/off the tape monitor switch a few times.

4) Keep track of whether this problem is sensitive to heat. Does teh channel shut down more quickly once the unit has been on for a while?

Lastly, if you can solder, look for any solder joint that appears grainy or has rings and resolder it.

Update this with your results and we'll continue on...

Thanks,
Dan

Looking for a good amplifier


Any 2-channel (or greater) receiver or integrated amp with at least one Tape Monitor loop; or any separate amplifier - will work. I would look fror one with true > 100 watts per channel, all channels driven, 20-20000kz + a few dB, with less than 0.5% Total Harmonic Distortion (in other words clean and powerful) should suffice. Specific brands don't matter. I'm partial to old Carver amps.

-----

However, should you get a multi-channel amp for the 901's you will be limited to using only 901's on it as the required Active Equalizer would affect all speakers attached to the amp, and conventional speakers would not sound right and could possibly be harmed by it's drastically-altered frequency response. Since using the Tape Monitor on modern DSP Receivers disables their digital inputs, that would limit what you could listen to, should you later decide to go with Cable Box, DVD, SACD, DVD-Audio, Blu-Ray, DTS etc.

* There are no some multichannel receivers out there that allow separating the preamp-amp circuitry for each channel to allow for differences in speaker processing. I think Marantz had one.

However, having a 901-based multichannel setup myself, I would highly recommend getting the Full Monte for video listening (below)...

In that case a separate stereo amp for the 901's would work. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.


Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

---------

So to sum it up, I think you should start with a powerful, clean amp with few bells and whistles for the 901's and maybe later add a multichannel receiver with all the magicfor source control, DSP and to drive the other channels.

Carver Sound Problems


your going to need this place to download the remedy's for your system http://www.euras.com/repair_tips_1/CARVER/AV505/AV505_CARVER.htm

if it is not working then there is another serious problem , and it could be the amp IC or the volume IC but tests will need to be done to determine what is causing the failure , but it does sound like amp IC as a suspect since the rear were not even working , did the volume seem different when turning it up or down before the center quit or after the center quit?
