IMPORTANT NOTICE - Please Read This:
Use of the LevelPad™ - The DP25/C SnareMic™ and DP30/C TomMic™ microphones have a high output level, which may overload the preamps of some
mixers or consoles. Many outboard microphone preampliers and preampliers 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” specications of your mixer or preamplier to see if it will accommodate signal levels this high. Some mixers and preamps will not handle this high
level at the microphone input. To avoid overload, please use a LevelPad™ in
the microphone cable feeding each Drum Periscope Microphones.
Some mixer or outboard preampliers have a pad that can be switched in or out.
However, some of these pads are not attenuators that precede the preamplier input, instead they only reduce the gain of the preamplier. 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 preampliers have actual pads
that precede the preamplier. 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, -10 dB or even –20dB may not be enough attenuation
when close miking snares or toms with Drum Periscope™ Microphones.
In any case where the pad does not precede the preamplifier, or the pad does
not provide enough attenuation, the Earthworks LP1530 LevelPad™ can be
used and will provide either –15dB or –30dB of attenuation. The LevelPad™
comes housed in a stainless steel tube with gold-plated XLR connectors on
each end. As the LevelPad™ is inserted in the mic line, it will always precede
the preamplifier input. It makes no difference if the LevelPad™ is inserted at
the microphone, or somewhere in the middle of the mic line, or by plugging

the LevelPad directly into the preamplifier input. The most popular practice
is to plug the LevelPad™ into the preamplifier input, which makes it more
accessible to switch the attenuation settings (-15dB or –30dB) if needed.
Figures 2-A, 2-B and 2-C show how the LevelPad can be inserted into the
microphone line in one of three ways as indicated below:
