How can I still hear my tuner when it's off?


With my amp and preamp on, if I set my preamp to tuner and crank the volume, with he tuner off, I can hear the signal; not at normal volume obviously. Anyone know why?

In case the question arises, if I move the selector to another input, it goes away.

your tuner may still be on electrically, but the display and output section is "muted" but still "leaking" enough signal to hear it. If you can still change stations, that is probably the case. Some products are built like this to retain memory, always be "warmed up", etc... One of my preamps has an on/off switch that doesn't work as you think it would. All the switch does is turn off the accessory outlets, as the preamp is always on.

What happens if you disconnect power from the tuner at the plug ? This will tell you if the tuner is still actively on somehow or if the tuner is somehow bringing in RFI. Sean

I follow you, I have had numerous units that have a standy by button as well as an off button. Seeing that the tuner, Fanfare FT-1A, doesn't have both, I assumed off was off.

I cannot change stations while the unit is off, as it's push button. I will have to try unplugging it some time.

It's no big deal, I was just curious.
Brianmgrarcom:

What kind of tuner do you have? If it's a Magnum Dynalab, what you're describing is normal (although a bit disconcerting). I've owned several MDs and still use one today, all of which exhibit this phenomenon. I actually contacted MD and sent one piece back to them because of it, only to find out later that this was normal and MD was not even aware of it at the time.

Normally one would never notice, unless the volume was way up there, so I suspect most people do not even know this is common. Go ahead and enjoy the tuner and rest assured that it is probably working properly.
Audiopman,

It is a Fanfare FT-1A, which Marv Southcott left MD and started Fanfare, so the fact that both these brands do this shouldn't be surprising. Anyway, I wasn't really concerned of a defect or I would of just contacted Marv, I was just curious about the why's and wherefores.

Thanks for sharing your experiences!
can you hear the tuner on any other preamp setting. you might be getting an rf leak from one of your interconnects.
espceially if they are long and unsheilded. this has happend to me on long leads to the mono blocks.

i have never owned a magnum dyna. but i have own(ed) carver;mac;nad;harmon kardon tuners. when they are off...no sound.

fwiw

Any component that has a remote control ON/OFF is never off completely. If it were off completely, there would be no power to receive the ON command from the remote. They are really on Stand-by.
Hi Brian,

You and I own the same tuner. I have not experienced the same problem but I think I understand why it is occuring in your system. The on/off function is not pure in that the off function does not shut down the component. In the Fanfare operations manual it explains that that the unit is always receiving some power and that this helps in that whenever the unit is turned on it does not require a warm up period to operate at its glorious best. I use the balanced output connections and maybe that is why I do not experience noise from the preamp when I switch to the tuner source and it is turned off. It also may be that I have never cranked it up so loud with the tuner off to experience low tuner noise. I hope that was helpful.

Thanks Drew, I do not think this is a "problem" though, as I have stated in reply to another, that if I thought it was I would contact Marv. I was just curious as to the how, I was under the impression this unit was off and not stand by, it appears that my assumption was wrong; this does not bother me in any way.

Also, I know nothing of the inner workings of these r audio in general, but I don't see where it would be any different using balanced IC's, either it's sending a signal or not. Try cranking it up sometime. I have owned mine for over a year and have never noticed it until the other day.

The difference with a tuner vs. CD (etc.) is that a signal is always there, in the air that is and if it's in standby mode, it appears it's still pulling it in.
