G One auto turn on/snap/hiss?

G One auto turn on/snap/hiss?

Just bought G one pair for close range listening. These have auto turn on and off. Problem is that they turn on if someone turns on the light in my house in any room. Not always but time to time. Tested, even when the rca cable is not connected to the speaker. I have other electronics having similar auto on/off without any problem like this. Also when turning on they make quite a loud snap sound, again without or with rca. Auto turn on is not very pleasant in a quiet room when someone turns on the light somewhere else in the house and the speakers turn on with loud snap. The same happens power cable connected before or after ups socket. Looks like manual on off cannot avoided?

Second issue wanted to say is that in my house I hear very well the hiss one meter from the speakers. This is when rca (signal cable) is not connected, pure hiss from speaker. When rca connected the same hiss volume. Cannot say anything about the decibel level, could be in 5 to 10 db 1 meter distance as factory quotation, but audible anyway. I bought these exactly for close range listening.
Otherwise good sound and build quality.

Perhaps you'll get a better answer from one of the staff at Genecec. But as far as I know the snap on sound is completely normal aswell as the hissing sound, even without a signal cabel attached.

About them turning on when lights are turned on might have something to do with the electrical installation in your house. Atleast my speakers do turn on if i i cut the mains power and then turn it back on again, the speakers do turn on by them selves.

Hi,

What "overhere" wrote is true, typically there is a slight turn-on sound (snap, pop) when the speakers are powered on from the mains switch or get activated by the ISS function.

ISS circuitry needs to be tuned quite sensitive so that the speakers turn on and stay on even when a very low level signal is being played. Sometimes this causes problems if the electrical system of the residence is somehow badly/wrongly made and other equipment cause large noise spikes in the mains signal. If the noise spikes are strong enough, they can trigger the ISS circuit to power on the speaker. It should be noted that we haven't ever been able to reproduce this in our lab/factory. Did you unplug the RCA cable from the speaker end of the cable?

All amplifiers produce some amount of background noise which is then reproduced by the drivers. We try to push this level as low as possible in all of our products and I can say that we compare really well with the competition. Typically noise is not being considered distracting even at near field (less then 1 meter). If you can clearly hear a noise signal at 1 meter distance, there is a good chance that your speaker units are somehow damaged. Of course it can be also that you have an exceptional hearing. Have you asked your friends, family members take on this matter?

Another thing could be that the surroundings and the room is so quite overall that he can easily hear the humming. I live outside the city, in a quite place and even I can hear the humming from a distance of about a meter. This is of course when there are no other sounds or noises in the room.

Maybe TS could try one of the speakers at a friends house for a few days and see if the same phenomena occurs with the random turn ons.
