Cell phone VS Monitors ??

[ethos]

I was in the studio today, and every time my cell phone started ringing,
my monitors would make a weird beeping sound. Like something you find in a Maelstrom in Reason.

It didnt bother me too much, seeing as i wasnt recording at the time, but
is this bad for the monitors in anyway?
any chance they will be damaged?

thanks.

.peace.

I don't think it will hurt them, and I'm giving you rep points for not asking how to stop it from happening again.

 

[ethos]

thanks man.

Many cell phones send and recieve impulses constantly (checking for messages, etc.). This can create noise on your recordings. Your best bet is to turn it off, or at the very least, get it out of the room.

And how is this going to happen? It's just interfering with the speakers not the mic or interface.....

I get noise sometimes from my computer speakers when i set my cell phone on my desk, half of the time I know I'm getting an incoming call before the phone even rings because I can hear the signal on my computer speakers. Your speakers won't be damaged at all, so just shut off that cell phone and keep on recording!!

I was making a general statement, not specific to this poster's question. I think I read it in the mixerman diaries that some cell phones in the vicinity of recording gear will introduce unwanted noise into the signal when they check for new voicemails and such. I've never personally experienced it, so it may be bunk. I would say that mixerman probably knows better than me. Phones also have a tendency to ring while you're tracking.

I agree, I never have had this happen to me, I leave my phone on vibrate and it has rang while I was recording, I could hear the interference in my monitors but it never made it to my recordings. (and the 66 rep points are for you!)

One time the church sound system started making this wierd, subdued, "pop pop pop pop pop" every couple of minutes. Kinda annoying. Turned out it came from the guy running the monitor board setting his cell phone on the mixer.

Thats a new one I leave my cell right next to my mixer! (and you also get 66 points)

There was no signal, and the phone was seeking a tower.

I live on kind of a busy street here, and sometimes when the taxis stop I'll start getting cb radio in my monitors. I can't make out conversations but I just get some wicked modulation and a bunch of static voices... maybe it's time for some better monitor cables!?

What studio are you recording at?

yup, i know before a call comes in.
so i was recording while it happened the other day, and it recorded the noise!
i dont know how it happened.

Damn these Madsion headz! hehe

Hey ethos....how you been?!?

 

[ethos]

yo yo.
whats up thane?
not much, learning a lot of new stuff in regards to recording.
you still down to come to the studio?
maybe show me some stuff and do a collab?

There was no signal, and the phone was seeking a tower.

Actually, I work right underneath a cell tower (it literally lives on top of one of our buildings) and mine still interferes with powered monitors (computer speakers). I believe the interference occurs when the transmitter in the phone cycles between bower states. While this occurs when seeking a tower, it also occurs to reach out and contact a tower when the tower contacts it. Then, IIRC, the power gets slowly scaled back until it reaches some SNR threshold and then gets bumped up a notch. At least I think that's what happens.

Anyway, when it transmits at the highest power (either because there's no tower nearby or because it is negotiating a new connection to the tower for an inbound or outbound call), that's when it generates the most interference. After that, you'll generally only get interference when you're far away from a tower and it is running in a high output mode.

Don't quote me on that. Everything I know about the subject is based on my assumption that it behaves similarly to the way I've read that WiFi behaves, which may or may not be correct.
