1 – PW1 Foam Windscreen
1 – Users Manual
1 – Case with foam insert
IMPORTANT NOTICE - Please Read This:
Use of the LevelPad™ - The DP30/C microphones have a high output level,
which may overload the preamps of some mixers or consoles. Many outboard
microphone preamplifiers and preamplifiers in mixing consoles will handle as
much as +24dBv at the microphone input, without distortion. We suggest that
you check the “maximum preamp input level” specifications of your mixer or
preamplifier to see if it will accommodate signal levels this high. Some mix-
ers and preamps will not handle levels this high at the microphone input. To
prevent overload, please use an Earthworks LP1530 LevelPad™ in the micro-
phone cable feeding each Drum Periscope Microphone.
Some mixer or outboard preamplifiers may have a pad that can be switched in
or out. However, some of these pads are not attenuators that precede the pre-
amplifier input, instead they only reduce the gain of the preamplifier. These (so
called) pads will provide no input overload protection from high level microphone
signals (see Fig. 1-A). In contrast, other outboard or mixer preamplifiers have
actual pads that precede the preamplifier. These types of pads will provide the
input overload protection that is needed (see Fig. 1-B). Such pads will typically
provide –10dB or –20dB attenuation. However, due to the very high output level
of the Drum Periscope™ microphones, -10dB or even –20dB may not be enough
attenuation when close miking snares or toms with DP30/C Drum Periscope™
Microphones.
