ACO23/ACO234 Page 2
INTRODUCTION
Thank you for choosing our crossover. We have taken care to include all of the features you need to make your system
sound its best. Some of the features are common to both the ACO23 & ACO234:
•
Back panel switches for selecting the operating mode of the crossover.
• Back panel switches indicating the selected range of crossover frequencies.
Both of these features have LED indicators on the front panel so you can see at a glance which mode the unit is in.
• Low frequency summed output designed
specifically for mono subwoofer applications.
•
Phase invert switches on all outputs.
• Individual level controls on every output.
We are sure you will agree that these crossovers are built to provide
extremely high quality frequency division for all
applications.
