Here's a bit of a trap for young players, or those who assume phantom = 48
volts. The old warhorse Shure FP42 four mics input field mixer (its been
around a long time !) actually has a published spec of 30 volts phantom
power, not 48...hell, it's not even T- power ! Heaven knows how they
arrived at that one ?? Might be ok with your cheaper condensor or electret
mics--which can live with lower phantom voltage....but expect a higher noise
floor and/or reduced headroom/ dynamics with more demanding mics !!
Just thought you should all know, for the sake of completeness.......lol !
