Introduction

Overview

The single-rack space VMQ-4 permits simultaneous monitoring of up to four audio sources with “voice quality” fidelity. Because each channel has its own dedicated power amplifier and speaker, the audio sources remain completely separate from analog input to output. When listening within “Ultra Near Field” distances of 1 to 3 feet, these discrete speaker outputs provide enhanced source distinction when compared to designs with four inputs mixed into a single output.
