Topic: M-Audio's response to 48v phantom power bug

[it-goes-to-eleven]

Here's a copy of an email I sent to M-Audio. Please send email to sales@m-audio.com and/or info@m-audio.com if you are also concerned about this problem.

A rep from your company recently addressed the list of bugs associated with the Microtrack 2496. Among them, was the underperforming phantom power supply. Here is a copy of the reply as posted to rec.audio.pro and rec.arts.movies.production.sound

"BUG:
- 30v max on Phantom on stead of advertised 48v

ANSWER:

I believe our marketing mentions "Phantom Power", but never states
48v.  We took a prototype down to an equipment rental store, and they
let us go through their mic closet.  The MicroTrack provided enough
power for everything we tried, from the U87 to Sennheiser shotgun mics
and some esoterics.   So, is this a complaint that a mic didn't work,
or is it a complaint that the Volt-Ohm meter needle didn't go where
they wanted?"



In fact, your marketting DOES specifically state 48v phantom power as is apparent from page 6 of your own 2005 Product Guide.

Likewise, every retailer and M-Audio dealer's website had advertised 48v phantom power before the MT's release (while they were still taking pre-orders) and most still advertise it even though it has been found that the unit may only deliver 30v of phantom power (according to Len Moskowitz of core-sound.com and others, see taperssection.com archives).

Even such major retailers as Sweetwater, BH Photo Video and AudioMidi.com are advertising 48v Phantom Power.

As such, I believe this is a product defect that should be fixed and addressed in later revisions. Despite what your own testing indicates, it is true that many mics will not function properly with highly underrated phantom power supplies. Schoeps has confirmed that it's 12-48v phantom mics will only operate properly when powered by 12v OR 48v, not 12 TO 48v..

I'd like to thank you for making such a great product. I'm sure if you can work out most of the firmware bugs, and bring the phantom power supply up to it's rated voltage, it will be a VERY succesful machine. Please let me know how, or if you plan to address this issue. Thankyou!
