Overview and

Introduction

The integration of the personal computer (PC) into

the home stereo system has provided a revolutionary

way to purchase, organize, and play your digital

music collection. The Ayre QA-9 analog-to-digital

(A/D) converter provides an equally revolutionary

way to store and play back your analog music via

your PC with unprecedented fidelity and realism.

The QA-9 is available in two versions, both covered

in this manual. The standard version include both

USB and AES/EBU digital outputs and will meet

the requirements of virtually all users. The Pro

version adds both DSD and word clock outputs for

simplified use in a professional studio environment.

The QA-9 utilizes opto-couplers to provide total

electrical isolation for the connections between your

computer and music system. This minimizes the

introduction of unwanted radio-frequency

interference (RFI), generated by all computers.

Avoiding the use of wireless networks (e.g.,

Wi-Fi), by employing wired connections instead,

will reduce RFI levels in your home and results in

improved sound quality for any music system.
