Studio 32 Phantom Power

[spicoli]

When using the phantom power on my Studio 32 I notice a hum when I have the volume up. It is not really noticable in a mix but but I find myself backing off at the trim. Are all 32's like this?
Thanks for ant info.

Wow, I'll have to check this. I noticed a boatload of noise on mine when the trims/pre's are above about 85%, but I never tested to see if it only occurs when the phantom power is on.
