DA-16X – User's Guide

Introduction

The DA-16X, Apogee's latest and most advanced digital to analog converter, takes the legendary quality of
Apogee a significant step forward. Features such as a redesigned power supply, standard 192kHz sampling rates,
the C777 clocking technology found in Big Ben, and optional Pro Tools HD and FireWire expansion cards, make
the DA-16X the most powerful and flexible D-to-A converter ever.
Advanced High-Definition Conversion
With up to 192k standard sample rates, the DA-16X combines Apogee's legendary conversion quality with
the very latest in high-definition digital to provide unrivaled flexibility and quality.
C777 Clocking used by Big Ben
The DA 16-X uses Apogee's C777 clocking technology. Famous for keeping Big Ben on time, the C777
utilizes an entirely digital process that Apogee has developed with the most advanced Direct Digital
Synthesis (DDS) technology and DSP-based digital filtering. With a stable, crystal based digital PLL
handling the clocking, the DA-16X is able to intelligently manipulate incoming signals and adapt to them
accordingly, resulting in unprecedented jitter attenuation and an astonishing and noticeable difference in
sound quality.
Advanced Option Routing
With version 2 firmware, both digital inputs and analog outputs may be routed in conjunction with an
installed X-Option card. Please see page 7 for details.
Universal Connectivity
With it's wide array of standard and optional digital inputs, the DA-16X can be connected to virtually any
digital system. The DA-16X includes AES and ADAT Optical digital inputs as standard, while either the
X-HD or X-FireWire cards may be installed for connectivity to Pro Tools HD or any FireWire equipped
computer.
High Performance Output
The DA-16X uses Apogee's newly developed electronically balanced line drivers, able to simulate true
transformer behavior. The circuitry is an ultra low output impedance, high current driver, capable of
running levels up to 26 dBu to the most complex or low impedance loads. Recording studios utilizing
vintage audio-equipment will find this particularly valuable. Ultimately, the output performance of the DA-
16X achieves perfect symmetry when used in balanced mode (even with an unsymmetrical load) and no
increased distortion when used unbalanced.
