INTRODUCTION
ADVANTAGE
®
EQ281/8 & EQ282/8 provide one or two channels of digitally
controlled 1/3-octave equalization in a single rack-space unit. Input levels and
28 filter bands, as well as high-pass & low-pass filters, are all adjusted via
computer. Eight presets (per channel) are recalled via contact-closures, third-
party controllers, or computer. Filter design utilizing Constant-Q technology
guarantees precise system tuning with less filter interaction, better filter
combining, and constant filter bandwidth at any setting. EQ281/8 & EQ282/8
