Introduction

The EQ901 Elite is an ultra high performance replacement for existing BOSE 901 Series I/II,
III/IV or V/VI equalizers. The unit provides the BOSE 901 specific equalizer curves with four
tone modes that accommodate a wide range of room conditions and recording variations.
Designed for use with high-quality pre/power amplifiers or integrated amplifiers and receivers,
the unit builds on our EQ901B series with lower distortion, greater dynamic range and higher
fidelity, providing audiophile-grade digital signal processors, DACs and analog signal stages.
