Looking for a small battery operated box that can provide 48 v phantom
power to 1 to 2 mics. The smaller the better.
Is there anything readily available that can be clipped to a belt or
easily attached to a Canon XL-1 DV camera?

Rolls and others seem - not big really but can this device be built into
smaller space? How much space does the electronics for such box need
anyhow?
