Introducing the Apogee X-Series.

Simply the best converters ever made... bar none.

he AD-16X and the DA-16X, Apogee's latest and

most advanced conversion systems, take the leg-

endary quality of Apogee a huge 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 AD & DA-16X the most

powerful and ﬂ exible conversion combination ever. And,

not only does the X-Series hardware offer unequaled,

groundbreaking technology but it makes it available at

a fraction of the cost associated with previous, premium

Apogee gear.

Advanced High-Deﬁ nition Conversion

The most critical component in the digital recording

environment is proper, high-quality conversion and

since the dawn of digital recording the most desired

converters have been made by Apogee. With up to

192k standard sample rates, the AD & DA-16X combine

Apogee's legendary conversion quality with the very

latest in high-deﬁ nition digital to provide unrivaled ﬂ ex-

ibility and quality.

Redesigned Power Supply

Enabling optimum conversion requires a state of the

art power supply. The fully redesigned power system

of the AD & DA-16X incorporates a specially designed

Synchronous Switching power supply that works in con-

junction with Apogee's very stable low jitter clock and

ﬁ ltering technology to provide superior heat and noise

performance and an improved transient response over

our previous linear power supply. This creates a power

system that delivers total efﬁ ciency and provides an

ideal environment for premium conversion.

16 Channel, 24bit/192kHz, A/D & D/A Conversion System

Redesigned Analog Section

Incorporated in the AD & DA-16X are the very latest de-

velopments in Apogee's groundbreaking analog circuit

design. Through sophisticated implementation and op-

timal conﬁ guration, the selection of premium, contem-

porary opamps allows the X-Series to deliver conversion

performance never before heard, while maintaining the

signature Apogee sound: Clear, transparent, focused

and punchy.

C777 Clocking used by Big Ben

The AD & DA 16-X use Apogee's C777 clocking technol-

ogy. Famous for keeping Big Ben on time, the C777 uti-

lizes an entirely digital process that Apogee has devel-

oped with the most advanced Direct Digital Synthesis

(DDS) technology and DSP-based digital ﬁ ltering. With

a stable, crystal based digital PLL handling the clocking,

AD-16X and DA-16X are able to intelligently manipulate

incoming signals and adapt to them accordingly. The

result? The most aggressive jitter reduction ever and an

astonishing and noticeable difference in sound quality.

Connect Directly to Pro Tools HD or any

FireWire Enabled Computer

Like their cousin the Rosetta 800, the AD & DA-16X

offer an expansion card slot that greatly increases con-

nectivity possibilities. Add an optional X-Series HD card

and connect AD & DA-16X directly to your computer via

your HD Core Card. Using Logic, Nuendo or any of the

many native DAW's? Add an X-FireWire card to your X-

Series hardware and enjoy a direct, extremely low laten-

cy connection that supports FireWire 800 standards and

has backwards compatibility with 400 standards. And, if

you are buying multiple units, you can daisy chain up to

a whopping 120 channels with incredibly low latency.

SoftLimit: Maximize Levels, Minimize Overs

One of the greatest difﬁ culties in digital recording is

getting an adequate level without clipping and un-

wanted distortion. Soft Limit is an analog peak limiter

that enables the capture of an additional 4-6 dB of level

without going into an 'over' condition. Short of purchas-

ing a very expensive stand-alone compressor/limiter,

there is currently no product on the market that handles

this process better than SoftLimit.

UV22HR: Dither Down with 24-bit Detail

UV22HR is Apogee´s industry standard technology for

reducing the word-length of a high-resolution digital

signal to 16 bits for the CD mastering. UV22HR is also

being employed to produce dramatically improved

internet and computer audio content without increased

ﬁ le sizes or data rates. It is estimated that 8 out of

10 hit records are mastered using Apogee's UV22HR

technology.

High Performance Output

The DA-16X uses Apogee's newly developed electroni-

cally balanced line drivers. Originally designed for the

Mini-DAC, these line drivers are 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 imped-

ance loads. Recording studios utilizing vintage audio-

equipment will ﬁ nd 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.
