Question about NAD C272 Amplifier

1 Answer

Speakers a & b are on at all times.

I can't find a way to toggle between speaker sets. The remote for the preamp has buttons for speaker A and Speaker B but it has no effect on the power amp.

Hi,

Your right, the remote will not switch the speakers.
There's no remote input on the power amp, so there's no possibility to switch between A and B speakers.

regards,
Gerard

I can't get sound out of my amplifier and I haven't changed anything. What could be the problem?


Start by choosing FM on a known frequency with a station broadcasting and volume is turned down to a NORMAL listening level. Next, make sure speaker selector isn't the wrong position (make sure "SPEAKERS OFF/A/B/A+B is set to A [or B to match the speaker terminal connections]), check to be sure "Mute" function is not activated by pressing the MUTE button on the remote to toggle it between on & off, Make sure headphones are disconnected. Make sure "PROTECT" is not displayed on the front as this indicates a shorted speaker wire - shut off and repair the shorted wire(s).

If you get sound on FM, but have an issue with another external component (CD, DVD, Phono, etc.) check the cables between the component and the input panel on the rear of the STR-DE595.

I hope this helps & good luck!

What is speaker A low imp . how to use speaker B.thank.


The Low Impedance setting is for when you have even one speaker with <8-ohms nominal impedance so you can use bot speaker pairs together. You still need to have an effective total (parallel) impedance of 4-ohms minimum or there may be problems like blowing up the amps.

Press and hold the SPEAKERS A or B button until LOW IMP lights or goes out, as required.

Press either button to toggle that speaker pair on or off.

It's in the manual page 14, 22 and 25.

Check to make sure your the 'Speaker' switch is toggled to ON. Press the 'Speaker' button on the front panel. Or on the remote, press 'Receiver' button on the top left area then the 'Speaker' button on the bottom right area.

Yamaha m70 amp and c70 pre-amp right speaker stopped working


First, lets's determine if it's the amp or the preamp...

Swap the Left and Right channel cables between preamp and the amp with each other.

Did it stay on the right? = amp problem.

Now on the left? Preamp or source.

Plug any Line Level device (CD?) directly into the amp inputs. Work now? Preamp problem.

ALL sources? Preamp - toggle all controls, especially a Tape Monitor to possibly wipe of any built-up oxides in them.

How do i hook up a B4.250.2 Amp to a home sterio?


Hello umbaftroml,

Here's a link to the owners manual: Scroll down to the B4.250.2 and right click "Download Manual".

http://www.lightningaudio.com/scripts/latech.cfg/php.exe/enduser/std_adp.php?p_sid=572kxbvj&p_lva=&p_faqid=154&p_created=1235512138&p_sp=cF9zcmNoPSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9OTEmcF9wYWdlPTE*&p_li=

You'll need some source of 12V DC power which is not available on your home stereo. A 12V battery or DC power supply will work OK. You'll also need to wire in a toggle switch to "trigger" the amp to turn on. Just put the toggle switch inline with a diode for isolation between the power wire and the "remote" terminal on the amp. Flip the toggle on when you need to use the amp.

The speaker connections and source connections are all shown on page 6 of the manual and would in any case, be the same as if you were installing the amp in a vehicle. Be aware that most home stereo speakers are 8 ohms, whereas speakers and subs designed for vehicles are usually 4 ohm or sometimes even 2 ohm. This will not be a problem. you shoud be able to drive 8 ohm speakers, they just won't be as loud because the amp will not produce it's full power into an 8 ohm load. Plug your RCA's into your home stereo's preamp outputs, or if there are no preamp outputs, use the speaker level inputs on the lower edge of the amp.

Hope this helps.

Just bought a Philips home theatre system HTS3544 low sound?


You may also need to change the speaker set up. Go to DISC setting (one of the top selections on the remote) make sure you have no Disc in the DVD player. When in this mode press setup on the remote. On this menu you will have a option to adjust the speaker volume.

I had to increase my speaker volumes to get better sound. This setting is not accessible if you try to do the set up in other than DISC setting. Be sure to check the SURROUND setting. The SURROUND button on the remote will toggle between stereo and surround as stated in a previous post.

No output, speakers dead. my system worked until I reached for the remote. I touched a button that lost all output.It is the same dvd, or radio, the radio shows tuned, I have tried everything I know no go....


If your receiver has A and B channel speaker selectors you may want to toggle through the two and see if the sound comes back. That could easily have been pressed from the remote. If not try hooking up only one speaker at a time. If there is a short, or blown speaker the amp will usually shut its audio off so it doesn't damage anything internal. Hope this is helpful.
