1. Introduction

ALTO-Q has 5 band Parametric Equalizer delivers outstanding equalization

both in live applications and in the studio.

For room equalization and extreme corrective surgery e.g. nothing out

unwanted frequencies (feedback etc.)
For gentle contouring and audio sweetening in audio post-production and

recording studios.
Parallel filter architecture ensures minimal phase shift and extremely

transparent audio performance.
Precision state variable filters with constant “ Q” principle ensure

absolutely stable filter characteristics.
High and low cut filters remove unwanted frequencies e.g. floor rumble

and tape hiss etc.

Each band can through “ in/out” swit ch and is fully adjustable from

extremely narrow notch filter (0.03 octaves) to broadband equalization

(1.6 octaves).
A wide overlap between frequency bands allows for extreme cut or boost.

Balanced input and balanced output with 1/4” TRS and Gold plated XLR.

With an auto-bypass function during power failure.

12 LED to indicate input or output level.
