INTRODUCTION
The DAX 3 is a two channel Dedicated Active Crossover designed specifically to be used with the Apogee
Acoustics Diva, Duetta Signature, Caliper Signature, and Centaur Major speakers. It provides exceptional
tuning flexibility, which enables users to sculpt a tonal balance to meet their exact listening requirements. The
DAX will accommodate a wide range of preamplifier and amplifier characteristics.
Features of the DAX 3 include woofer and midrange/tweeter level controls, fine level adjust controls, and rake
angle level adjust controls. These controls facilitate ergonomic operation and easy adjustment. The rake angle
control provides proper integration of the speakers' midrange/tweeter transducers with the audio system and
listening environment. The DAX 3 is capable of operating with single-ended or fully balanced input-output
signal interconnects. Input impedance adjustment controls fine-tune the matching characteristics between
DAX 3 and most available pre-amplifiers. Selectable amplifier gain matching provisions ensure total system
compatibility.
INSTALLATION
WARNING: DISCONNECT ALL POWER AND CABLES TO THE DAX BEFORE MAKING ANY
ADJUSTMENTS!
1) DAX ADJUSTMENT SWITCHES (See Diagram #1)
Inside the DAX are two output printed circuit boards for the left and right channels. There are a number of
switches on each output board which are used to select gain settings for matching amplifiers with different
output levels, filter shapes for the selected Apogee loudspeaker, balanced or single-ended inputs, and various
input loading settings.
If your authorized Apogee dealer has already performed these adjustments for you, proceed to section 2.
REMEMBER!: WHEN ADJUSTING SWITCHES ON DAX OUTPUT BOARDS, CONCURRENT
CHANGES MUST BE MADE FOR LEFT AND RIGHT CHANNEL OUTPUT BOARDS!
