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, threeway electronic crossover featuring a unique set of outputs.
AX 30
ACTIVE STEREO CROSSOVER
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 connected to subwoofers and tweeter arrays. Additionally, the
SUB BASS OUT has a pre-level SUB BASS INSERT loop.

ACTIVE STEREO CROSSOVER
햲 SUB BASS level control: sets the level of the left and right SUB BASS OUTs. Controls the amount of desired low end.
햳 FULL level control: sets the level of the left and right FULL OUTs. Affects the level of full-frequency program material.
햴 TWEETER level control: sets the level of the left and right TWEETER OUTs. Controls the amount of desired high end.
햵 POWER INDICATOR LED: A lit yellow LED indicates there is power to all circuitry and the unit is ready to operate.
햲 Remote power supply input: This unit is supplied with a Rane RS 1 Remote AC Power Supply suitable for connection to
this input jack. The power requirements call for an 18 VAC center-tapped transformer. This is not a telephone jack. Never
use a power supply other that the one supplied or a replacement approved by Rane. Using any other type of supply may
damage the unit and void the warranty.
Chassis grounding screw: A #6-32 screw is used for chassis grounding purposes. See CHASSIS GROUNDING below.
햳 TWEETER OUTPUTS: Connect to the tweeter power amplifiers. Fully differential active balanced Outputs. Bandwidth is
7 kHz to 65 kHz.
햴 FULL OUTPUTS: Full frequency range Outputs available to drive subsequent crossovers or other equipment. Bandwidth
is 20 Hz to 65 kHz.
햵 SUB BASS OUTPUTS: Connect to the subwoofer power amplifiers. Fully differential active balanced Outputs. Bandwidth
is 20Hz to 100Hz.
햶 SUB BASS INSERT JACKS: Subwoofer insert jack wired according to the tip=send, ring=return convention. Use to add
additional effects boxes in series with SUB BASS Outputs. Signal path is before the LEVEL control.
햷 INPUTS: Balanced active differential Inputs (transformerless). Connect to the main program feed lines coming from the
console or other full frequency source.
CHASSIS GROUNDING NOTE
If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding
configuration between units somewhere. Here are some things to try:
1. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord
grounding pin or the rack screws to another grounded chassis.
2. Units with outboard power supplies do not ground their chassis through the line cord. Make sure these units are
grounded either to another chassis which is earth grounded (such as the amplifier).
Please refer to RaneNote 110, “Sound System Interconection” (included in this manual) for further information on
system grounding.
