A15RF -- In-Line Interference Attenuator
General Description
The Shure Model A15RF In-Line RF Attenuator
provides all types of balanced audio systems
with greatly improved immunity to radio frequen
cy interference (RFI). It is especially useful in ap
plications where balanced audio devices near
strong RFI sources, such as AM radio stations,
are connected by long cable runs.
The A15RF will not degrade system sound quality
or alter system frequency response. In cases
where interference is present but not audible, the
A15RF can improve perceived sound quality by
removing low level interference components
from the audio signal path. It passes phantom
power and is transparent to differential audio sig
nals ranging from DC to 2 GHz.
The A15RF is a passive device and will not dam
age other equipment. It does not present any ad
ditional load to the signal sources, and can be
used with phantompowered miclevel or linelev
el devices.
