SPECIAL NOTE REGARDING PHANTOM
POWER
The Meridian preamp works on 12-48 volt phantom
power or on 12VDC power via a suitable power
supply like the one we sell for this microphone
system.
Phantom power is unfortunately not 100%
standardized and differs in respect to how clean and
hum-free it is. “Dirty” phantom power may
introduce a more or less noticeable hum into the
signal and when connected to preamp devices, the
preamp circuit naturally amplifies this noise. In
situations you need studio quality noise
specifications we recommend to power the Meridian
preamp with its designated 12VDC power supply
and switch the phantom power supply off. This will
guarantee noise free operation.
