Signal Levels; Signal Source - Guitammer ButtKicker Concert User Manual

Signal Levels

The amplifier you use to power the ButtKicker
require a specific input signal level from your system's
control center (receiver/processor/preamp) in order to
deliver full power output to the ButtKicker. The level
of input signal required will vary from model to model.
There are two standard levels prevailing today. One
standard level is 0.15 volt (common in "consumer"
equipment) and the other is 1.5 volt (more common
in higher power and "professional" equipment). The
signal levels reaching the power amp must be able to
drive the amplifier to its full power level. If connecting a
consumer preamp/processor to a professional amplifier,
then a device will be needed to boost the signal level to
the level necessary for the power amplifier. Insufficient
signal levels from the system control center will not
drive the power amplifier to full output power. Please
refer to the user manuals of your equipment for specific
operating levels. Figure 4 shows a proper system level
setup. Please note that if your preamp has nominal
output levels of 1.5 volts, then no level conversion
is necessary; the preamp should drive the amplifier
directly.
PreAmp Output
level -10 dB

Signal Source

The ButtKicker responds accurately to any low frequency
information sent to it from an amplifier. The source
can originate from a mixing console, a processing unit
(a bass POD for example), an electronic drum head
unit, an acoustic drum pickup via the mixing console,
and the line level out from an amplifier.
