IMPORTANT NOTICE - Please Read This:

Use of the LevelPad™ - The DP30/C drum 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 mixers and preamps will not handle this high level at their microphone 

input. To avoid overload, please use a LevelPad™ in the microphone cable 

feeding each Drum Periscope Microphones. 

Some mixer or outboard preamplifiers have a pad that can be switched in or out.  

However, some of these pads are not attenuators that precede the preamplifier in-

put, 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, -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
