AX 30
ACTIVE STEREO CROSSOVER
Data Sheet-1
General Description
The AX 30 Active Crossover is a special purpose stereo
electronic crossover designed specifically for the recorded
music playback club or lounge, operated mainly by a live disc
jockey. Other applications exist; and the Model AX 30 can be
found in several fixed, live music arenas as well. The many
applications and usefulness of this product are limited only by
the imagination of the user. The design and construction of
the Model AX 30 are to the highest standards, befitting its
selection as the key ingredient in many of the top clubs in the
world.
Functionally, the Model AX 30 is a two-channel, three-
way electronic crossover featuring a unique set of outputs.
There is a SUB BASS OUT with a bandwidth of 20 Hz to 100
Hz; a FULL OUT with a bandwidth of 20 Hz to 65 kHz; and a
TWEETER OUT with a bandwidth of 7 kHz to 65 kHz. The
SUB BASS and TWEETER OUTS have front panel controls
allowing l6 dB of boost and 60 dB of cut, while the FULL
output has a front panel control ranging from 6 dB of boost to
-60 dB cut. The Input signal is thus divided into a buffered
and subsonic filtered full-spectrum output to feed the main
system crossover, as well as two special purpose low and high
end drive signals to feed additional power amplifiers con-
nected to subwoofers and tweeter arrays. Additionally, the
SUB BASS OUT has a pre-level SUB BASS INSERT loop.
