ACTIVE ELECTRONIC PHASE COHERENT
CROSSOVER
INTRODUCTION
The XO-1© is a fully programmable electronic crossover, which allows a
frequency change via a replaceable resistor network. Any frequency of crossover
can be selected between 32Hz and 12,500Hz in 5% increments. The network
can be easily inserted or removed from the special "quick change" I.C. latch
socket. The XO-1© makes possible both bi-amp and tri-amp systems with a
separate channel of amplification for each driver. A signal amplifier system
requires that the amplifier reproduce the full audible frequency range and power
multiple drivers through a passive dividing network. In an active crossover
system, one amplifier channel powers only one driver and must reproduce only a
part of the frequency range. The three main advantages of an active (electronic)
crossover are;
1. That a high order of inter-modulation distortion reduction can be realized due
to non-interaction between high and low frequencies, yielding improved clarity.
2. The elimination of the passive crossover itself. The elements of the crossover
absorb power from the amplifier and may cause distortion. In addition, the
capacitors and coils of a crossover create a reactive load that is difficult for an
amplifier to drive compared to the more purely resistive load of the driver.
3. A passive crossover system requires approximately 3dB more power than an
active crossover system. In other words, an active crossover system requires half
the total power of a passive system.

Page 2: Technical Description
As the XO-1© contains no user operated controls, the best mounting location is close to the amplifiers. The XO-1© should be mounted in a position such that the access plate (the one with no wires) can be removed for easy frequency change, and that the output fan-outs can plug directly into the amplifiers. - Page 3 Your XO-1© can be connected in one of several ways: A. Connect the XO-1© red wire to the power antenna wire of the music source if the power antenna wire is "hot" when the source is on. The power antenna wire is turned off on some units when the antenna is raised up all the way or when the tape selection is used.
- Page 4 In a mono subwoofer system, the low frequency amplifier's outputs are strapped together (bridged) by the XO-1© to sum the power of both channels into one to drive a single 8 ohm woofer. In this configuration, both of the speaker ground wires are unused and should be taped and dressed away from the other wiring.
- Page 5 OPERATION/ADJUSTMENT/USE 1. CROSSOVER FREQUENCY SELECTION A. Remove the access plate on the XO-1©. IMPORTANT: IT IS NECESSARY THAT ALL POWER TO THE SYSTEM BE TURNED OFF PRIOR TO NETWORK REMOVAL/INSERTION. WE REPEAT THE WARNING: DAMAGE TO YOUR SPEAKERS CAN BE...
