No Sound: Could It Be My Amp?

Mass. Wine Guy · « **on:** 3 Apr 2016, 11:15 pm »

I have a simple two channel system consisting of a Virtue Audio Piano M1 cd player, Quad 12L speakers and a BelCanto eVo2i integrated amp. Connectors are all Anti Cable.

I hadn't used the system in a while and when I first hooked it up recently music seemed fine. Then one day soon after any cd I played skipped tracks. I had the player checked and my tech found nothing wrong. Today I got around to trying again and there's no sound at all. I checked the connections and that mute wasn't on. Also verified that all the amp's inputs were enabled.

I can't figure it out and would be very grateful for suggestions.

Test the rig with other CDP, if it works bingo, if not bongo.

Any other source will work fine to see what is working and not. If you don't have another CD player you could use a DVD player, smartphone or laptop earphone out if you have a 3.5mm? to RCA adapter.

Don't forget to check the fuses on everything. Are there configuration settings for the CD player that need to be re-input since it was serviced?

If you suspect the amp you could perform a reset on it.

Another way to check your system if you dont have a source is
disconnect the ic's from the cdp,turn max vol preamp/pwramp
and touch the ic with your hand,then put your ear close to speaker
and listen for hum/ic noise if you do all is good and the cdp is at fault

cheers

WHAT??!!! TURN THE VOLUME CONTROL TO MAXIMUM? MAXIMUM?

That not only will possibly blow his speakers but could damage his hearing.

Specs on OP's amp.
Power output per channel into 8 ohms • 120 watts <1% THD+N
Power output per channel into 4 ohms • 200 watts <1% THD+N
Bandwidth: +/- 3dB •1Hz-80KHz

Make sure you did not accidently engaged the Tape Loop circuit.

I agree.

Never go Full Volume when troubleshooting!!!

Sometimes I don't know who is joking and who isn't, but besides the above recommendation being risky, I'm not sure how it would help determine the cause. IOW - There are better, easier ways. Like pretty much all the other suggestions

oh yeah?,a few milivolts of noise can be harmful? when some drive it with 3V peak! source.
JerryM you don't understand the principle ,I understand

Really time to time huh. Last time I checked I have been a member of AC longer than you.

I just hope the OP read my response to your idiotic post and didn't try what you suggested. Why would anyone want to deliberately try to blow a guys speakers.

Tell you what, why don't you try what you wanted the OP to do on your own audio system. When you try the test make sure you crank the volume control up full bore. Then just to drive your point home touch the center pin of each un-ported IC to get the full affect.

Don't forget to put your ear up against the speaker so you will hear it real good.

Please post back the results of your unforgettable experience.

Best of luck.

you dont understand anything!!!
all i'm saying if you play a system with 3v peak,how come a few millivolts peak of noise be harmful??
do the maths!!!

For heaven sakes, guys. Lighten up! I don't want any fights in my posts.

I don't listen to math. I listen to speakers.

Try your test for yourself. Post back your results. Don't forget to touch the un-ported center pin of each IC.

JerryM · « **Reply #18 on:** 5 Apr 2016, 03:40 am »

The only way one can get a 3v peak is by playing at FULL VOLUME.

I have a conservatively rated 280 watt amp. I have 91 decibel speakers. My preamp has 20 dB of gain. My pre probably runs at 2v max out. Do the real world math at that. What does that sound like in my listening space while troubleshooting??

Seriously, never ever ever go full volume when troubleshooting. There's just too many other viable options available that won't blow things up..

how can i do the math??you dont give the spk impendance st***d!!!,280w with 91db spk
20db gain, 2v input, rms pwr at 4 0hms is 100w rms,seriously you're st***d,i'm wasting my time here

omg,wtf,2v input from cdp x 20db gain = 20v max out,sorry mate but i can't make sense,sorry
