Introduction

The AudioConnect

TM

 USB audio interface is designed to meet the majority of audio test and measurement 

needs. It is specifically designed for audio and electroacoustic test and measurement. It offers two channels 
of analog input and output as well as two channels of digital I/O, USB control, and a power indicator. All
