ACTIVE CROSSOVER

INTRODUCTION

The Apogee Acoustics, Inc active crossovers is designed to provide electrical

separation of woofer and midrange/ tweeter signals for bi-amped or tri-amped

systems. This is accomplished at the signal level between the pre-amplifier and

power amplifiers in a manner to provide the most coherent and musically accurate

result. The active crossover approach provides a high impedance to the pre-amp

drive and low source impedance to drive the power amplifiers. The audio system with

the active crossover consequently provides excellent resolution and overall

performance plus the convenience readily working with a brand range of amplifiers

ADJUSTMENTS AND USE

The active crossover is set at the for factory for proper operation with the

following Apogee speakers, large Full Range, Scintilla and the Duetta Series II.

The active crossover may be operated as a two-way or a tree-way crossover when used

with the Full Range Apogee's. The active crossover or may be operated as a two-way

crossover for use with the Scintilla and Duetta Series II.

Be certain that you are utilising the active crossover that is designed for use

with the correct Apogee speaker model. Each speaker model requires a different

active crossover network. You may select either and active crossover that is

compatible with both the Full Range Apogee and the Scintilla or an active crossover

that is compatible with the Duetta Series II.

The control pots on the front of the crossover, when used in the dedicated bi-amped

configuration, provide for attenuation of the woofer and midrange/tweeter channels.

The attenuation has a resolution of approximately 1/4 dB with an infinite range.

The active control pots are the left and right channel woofer and the tweeter pots.

The midrange pot is inoperative in a bi-amped configuration.

The frequency response slope at the crossover frequency is 6bB per octave. The

slope well beyond the crossover frequency is increased to provide greater

separation between the woofer and midrange transducers.

IMPEDANCE

The crossover input, impedance is river 100K ohms and the output impedance loss

than 1K ohms. These impedance levels will function properly with most modern pre

and power amps.
