Running Mic through Phantom Power

Hello all! Im having a bit of trouble here. Running a MK-319 Condenser Mic through a Phantom Power adapter, then through a Lexicon Alpha (audio interface) to my USB. I can't get a signal with GarageBand08. Any help would be much appreciated. Hope Im not being to vague.....

o.k., I'll do my best to answer that. Done=I've Created a drum track(loops). Set=? Changed=I've changed my input/output settings on both my Hard Drive & GarageBand Preferences to Lexicon Alpha. Created=I made a track with my giutar through the audio interface.... Im sorry, Im sure that didn't help at all. Im kind of new to all of this...

Do i need phantom power for a condenser mic to use with garageband?

i have learned condenser mics need phantom power. if i would hook up a MXL 900 series condenser to my MacBook via an XLR to 1/8" cable, would it work? does garageband have some sort of amplification plug-in? or would i need some sort of mixer or otehr phantom power device for it to work?

condenser mics need phantom power to work at all, it has nothing to do with amplification.
you need an interface or mixer that supplies phantom power, or an external phantom power supply to use your condenser mic.

Why does 10.5.0.142 update playback sound as if it were being played through scuba diver mic with a power saw in the background?

What in the world have they done now? After down loading your latest iTunes update (10.5.0.142) the podcasts and radio and any music stored on the iTunes sounds as if it were being played through scuba diver mic with a power saw in the background - nothing can be understood. CD play back is fine. Please tell me how fix this or how to go back to the previous version.

Same problem here. Sounds like Zarvox on my iMac, but way worse. Gonna do a bit of research around iTunes Support site. I should have learned a long time ago--wait a few days before updating. THIS IS VERY ANNOYING!!!!!

Phantom power for a USB mic

I'm interested in a USB mic made by SE Electronics USB mic (2200A). It has zero latency because it has a built in headphone jack. The only problem is that it requires 48V phantom power. The only phantom power units I've seen online don't have USB or even 1/4" inputs. (they're all three pin mic inputs) How do I get phantom power for a USB mic?

it doesn't need an external poser supply when used as a USB mic.
I'm assuming you mean "power" supply? And that the mic in question only needs phantom power
if used with a 1/4" adapter going into an interface or preamp, but if directly plugged into the Mac USB port, it needs no other power supply? The salespeople at the store know nothing!

T60 Microphone input: Stereo? Mono? Phantom power?

Hello,
Does anyone understand the T60 mic input. It seems to me that it a mono input, but if you plug a stereo cable in it, the middle ring on the cable actually gives a 5 volt reading if you put a volt meter across the middle ring and ground. Is this possibly some sort of phantom power and wouldn't this be shorted out if you plugged a mono plug into it? I would think that shorting a power source would be a bad thing.
Thanks for anyone's help,
John

It's a mono input, and it is worthless in my opinion. The 5 folts is probably spurious, and shouldn't be there. If you have tried to record direct from this input, you will probably hear a load of noise in the recording.
At least, that's what I get on mine. Really made me angry, as I had to buy a Soundblaster add-on card to get decent recording.
Phantom power is generally a lot higher than 5 volts, but a lot of things in computers run on 5 volts.

Phantom Power On, Gain Still Too Low

I am running STP on a MAC Mini with M-Audio Firewire Solo and I can't seem to realize any difference between a dynamic and condenser mic input. I turn Phantom Power on on the Firewire Solo but I still have to crank up the gain. The condenser mic is brand new too. What's up?

Probably a mispcerception. Why do you think phantom power would help?
If you have a battery in the mic, phantom doesn't apply.
If you don't need a battery in the mic, phantom doesn't apply.
If your mic requires power and none is applied, the preamp does nothing, there is no signal available at all from the mic.

Logic Will Randomly Lose Phantom Power

I have an Apogee One running into Logic Studio 9. On the Apogee One, I am running and XLR cable to an Apex Microphone, and a 1/4" cable to a guitar (At Different times). When recording either the Guitar, but most commonly with the Phantom Power on the 48V Input, the Microphone will drop out temporarily and not pick up any sound, then slowly it will fade back in. This happens every couple of minutes during a recording. We have already replaced the Apogee One, but the issue still seems to occur.
Any Suggestions?

Hi
This sounds like an issue with the audio interface, not Logic. Does the interface work ok on another computer? If it can, run it with a separate power supply, rather than bus-powering from the Mac.

I had similar problems and could get nothing whatsoever when trying to record from the microphone or using it in Skype (it was obviously muted completely in some way). Tried everything I could in alsamixer, and installing PulseAudio didn't manage to get it working either.
However I installed gnome-alsamixer, and ticked a few 'Rec.' check boxes and everything works now as it should! Sorry I can't pin down exactly what switched it on.

M-Audio Firewire 410 phantom power

Hi
I have a condenser mic and wish to use it with my m-audio firewire 410. I have tried everythiong to get it working but no luck. The phantom power has no effect. There is no levels when tested on the m-audio box. What will make the mic work. I believe it to be more the hardware than the software
Cheers!

i suppose you have pressed the button on the left(phantom power) of the interface and you see it on (red),right?
do you have selected the mic instead of line in the front?
do you have the pad pressed by mistake?
move the gain pot to see levels?
if the above are correct you should have sound.

I need help interface/phantom power

i'm going to be purchasing the nt2-a studio condenser microphone but i'm under the impression i will be needing to buy an interface, could which interface i get affect audio quality etc, i will only ever be using one microphone at a time.
Which interface should i get and what should i know as i've only worked with usb microphones before?
Do i need to buy a phantom power also?
Do i need to spend 100 odd on an interface or will this work http://www.ebay.co.uk/itm/XLR-to-USB-Interface-convertor-with-48v-Preamp-phantom-power-/16 1105081721?pt=UK_Musical_Instruments_Preamps&hash=item25829c7579
What is my cheapest option?

I must confess that I'm slightly at a loss to understand why you want to purchase one of the quietest condensor mics around and then feed it into a piece of junk like that ebay item. The mic will considerably out-perform it. Yes, you need phantom power for this mic, but if you want to use it to anything like its capability, then you'll need rather more than the cheapest usb interface for it.
You'd be better served by the (cheaper) Behringer Xenyx 302 USB Mixer and interface, or for not much more, the ART USBMix 3 Channel Mixer w/ USB Audio & Phantom Power. Even though I'm personally not a huge fan of Behringer, either of these will do a better job, because the preamps in them aren't anywhere near as compromised. At this price level though, (only 16-bit A-D) you still won't be able to get the full benefit from it. To do that, you're going to need a more expensive system with a better converter.

Does an iMac have phantom power?

Stupid question, but just on the off chance. Is there anyway to power my Samson C03 condenser mic, which needs a phantom power supply, from the iMac. I'm using the Samson S phantom power supply at the moment and am getting a really annoying hum. I'm guessing its something to do with the grounding in my plug socket, but I don't know anything at all about electrics. Does anyone know anything about this?? Cheers

FWIW, I was playing around with a friend's interface this past week. It's a newish interface, nothing fancy, but not too cheap either. Anyway, it has both balanced and unbalanced outputs. For some reason, hooking up the unbalanced outputs to the monitors had a weird noise on them, not a typical grounding noise, while the balanced outputs to the monitors was noise-free. Go figure.
So... if there is a choice, balanced is better!

Condenser mic through PowerMac G4 audio line-in

I just picked up a MXL M.A.R.K. condenser mic and a Rolls Mic Power I 48V phantom power supply. I'd like to start podcasting using GarageBand. I've connected the mic to the PowerMac G4 audio line-in port and select Line-In in the GarageBand preferences. However, the mic audio is barely discernible...even with volume inputs all the way up, which of course increases the noise. Anyone have any ideas how to take advantage of this condenser mic? Is Griffin's iMic required? Does the phantom power supply appear defective?

Phantom power problem -Samson CL8 and M-Audio unit

I just got a samson CL8 condenser mic and only get buzzing in GB when I plug it into my M-Audio MoblilePre USB interface and turn on the phantom power. I have it connected with an XLR on the mic end which goes into the USB interface with a 1/4 (not sure if that's an issue but I use the same cable with my SM58 with no problems -but of course that one doesn't need phantom power). Anyone know what this could be?

why would that work with an SM58 just fine
because an SM58 doesn't need phantom power (also, "fine" is debatable, you're not getting everything out of that mic that you could be. it should be plugged into a Mic jack, not a line-level jack)

SB Audigy 2 ZS Plat Pro and MXL 990 Phantom power microph

I recently acquired the microphone which is "phantom power".
I am presuming that it is not compatible with the sound card, would that be true?
if any walkaround could be suggested so that i can use a better quality mic with the sound card it would be much appreciated.
phantom power 48v +/- 4 (if that means anything).
I will be getting a mixer soon as well to aid a variety of projects but all my hardware is sourced at relati've low cost so compatibility issues cannot be tested in advance. again if there are any issues with connecting to the hub it would be good to know.
cheers

MBP running out of battery power before sleeping - Help!

Hi
My MacBook Pro has been running out of battery power before the memory-saving sleep mode kicks in, so it dies with a little click of the HD. It's not a hibernation state as when I reattach the power supply it boots up a new session.
I've noticed this since upgrading to Snow Leopard last year, but put it down to an old battery that had 45% charge and wasn't powering the MBP properly. I now have a replacement A1175 5600mAh battery which is giving me 2-3hrs usage (which I'm pleased at), but now it still dies before sleeping!
I have tried to cycle the new battery, but can't. I have reset the SMC several times, with no effect.
I used to cycle the battery every week or two, running it down until it would no longer wake from sleep, recharge overnight etc, but now I can't do this because it will die before sleeping!
I've read quite a few articles over the net about this issue, but there seems like no cure. It's really annoying me now as I frequently work on the move and a dying MBP could potentially be disastrous.
Can anyone shed some light on this issue? Is there something I haven't tried yet? I think it's a late '06 MBP.

If you are not getting a warning, then there is something amiss with your battery. If a SMC reset and calibration does not fix the problem, then you may need to make an appointment at the genius bar and arrange to have your battery tested.
My old battery started doing the same thing--shutting down without warning. I replaced it, and the replacement battery started doing the exact same thing. I then returned the replacement, and the next replacement battery behaves in a normal fashion.
My first battery was worn out. My second battery was defective. My third battery is good.
Your battery should still be under warranty. Go back to where you got it and show them what it is doing and see if you can get a replacement.
Good luck!
