Consult the manufacturer of your pre-amplifier or signal source device to determine the impedance
loading that the device works best with. Most manufacturers have conducted extensive tests on the
effects of impedance loading and should be able to answer this question. Select an impedance loading
value equal to or greater than the manufacturer's recommendation. If you cannot obtain a satisfactory
recommendation, choose the highest impedance setting for use with tube equipment or mid-value setting
for solid state equipment..

2) Required Wiring Modifications to Apogee Loudspeakers for Use With DAX 3
The following speaker wiring changes must be performed to permit operation of the Apogee speakers
with the DAX active crossover. The wiring changes are simple and readily performed.
WARNING!: BEFORE MAKING ANY WIRING CHANGES, DISCONNECT ALL POWER TO
THE AUDIO SYSTEM.
DIVA (See Diagram #2)
The Diva is a three way speaker and the DAX is a two way active crossover. It is necessary to use the
standard Diva passive crossover for the tweeter. The tweeter HI, LOW, NORMAL switch remains active
while the rest of the switches are not.
The DAX comes with a modification kit for the Diva passive crossover when purchased for use with the
Diva. The kit includes (2) midrange coils designated "L5", (2) WHITE wires for woofer ground, (2)
GREY wires for midrange ground, a 3/8" socket wrench for removing the nuts on the binding posts, and
an allen wrench for removing the bottom cover of the passive crossover electronics box. If your Diva's
serial number is before #10360, a small amount of soldering is required and you will need at least a 40
Watt soldering iron to continue.
WARNING: IF YOU ARE NOT MECHANICALLY INCLINED, HAVE YOUR APOGEE
DEALER PERFORM THESE MODIFICATIONS.
