 That is *absolutely not true*. Any website that
 claims that you can safely connect a phantom
 powered mic input to any balanced output is
 providing very bad advice to its readers.
 It depends on *how* the preamp output is balanced.
 If it has a transformer to balance the output
 there will be no problem.
 If it is 'actively' or 'electronically' (!)
 balanced it depends on the if the designer
 has allowed for phantom power or not. In
 many cases the answer is *no*. 
Unless the DI/Preamp gets its power from the phantom-power. Then the answer is
actually "yes" :-)
Confusing... Rule of thumb: Try without first, if there is no sound, unplug,
switch on the phantom power and plug it in again to see if that helps.
