PSX100v2/5M/1198

High resolution. Apogee quality.

Multiple Interfaces,

UV22HR & Soft Limit

The PSX-100 includes built-in interfaces for ADAT, TDIF, S/PDIF

coax and optical plus multiple AES/EBU.

Other features include Apogee's newly-

enhanced

UV22HR

word-length reduction sys-

tem (which can be applied to either the A/D

or the D/A) and

Soft Limit

for maximum

A/D level without overs.

An auxiliary AES output allows a full-

resolution output to be supplied, even

when UV22HR is in use on the main outputs. The

wide range of standard interfaces provided, including multiple

AES I/O ports, allows the unit to be used for signal distribution

and format conversion as well as for A/D and D/A applications.

The inclusion of 88.2 and 96kHz sample rates makes the PSX-100

ideal for such applications as mastering high-resolution CDs uti-

lizing 88.2kHz sampling, or for DVD-Audio masters sampled at

96kHz with 24-bit resolution. Meanwhile, the inclusion of UV22

to reduce the word length from 24 to 20 or 16 bits makes the unit

equally suitable for traditional 16-bit CD mastering or for DVD-

Video soundtracks requiring 20-bit signals sampled at 48 kHz.

High Resolution on your MDM

Built-in Apogee Bit-Splitting (ABS) modes allow

the two-channel 24-bit signal from the PSX-100

to be recorded and replayed using pairs of

tracks of a 16-bit 44.1/48kHz sampling recorder, via ADAT, TDIF or

AES/EBU. With Apogee’s new

ABS-96

mode, you can even record

stereo at 96kHz sampling on your existing 16-bit 8-track! An

optional video sync card allows the PSX to lock to NTSC/PAL

color and monochrome video.

Instant Access

The PSX-100 matches Apogee’s popular 8-channel AD-8000 in

appearance, with a distinctive purple front panel inlaid into a

solid aluminum extrusion, and large silver buttons allowing

instant access to the unit’s extensive feature set.

The two light-bar meters can be set to read either the A/D or

D/A when the two units are passing different signals, and other

functions are indicated by an array of LEDs. As a result, there is

no need for a power-on indicator.

A multi-voltage linear power supply is incorporated, including

a true toroidal transformer with comprehensive regulation and

smoothing circuitry to minimize voltage spikes, transients and

noise that can adversely affect converter performance. A gener-

ous exposed heat-sink keeps temperatures well under control.

Virtually the entire rear panel of the PSX-100 is occupied by

interface connectors including two 2-channel AES inputs and

outputs. Both connectors are used for 96kHz operation; at

44.1/48 kHz, they operate independently. A ten-way DIP switch

allows the setting of system-wide defaults which are intended to

be set once and then left alone. Capabilities include pro and

consumer analog I/O levels; pin 2/3 hot; setting the OVER LEDs to

two seconds or infinite hold; and how overs are defined (1-4 suc-

cessive full-scale digital values). Bit-split signals may optionally

be received on the AES/EBU inputs (for Sony PCM-800 users and

others who wish to use bit-splitting on an AES/EBU device). Word

clock output has two modes: it can follow the sample rate, or it

can be set to generate 44.1/48 kHz even when the sample rate is

set to 88.2/96kHz.

Three Operating Modes

A central design feature of the PSX-100 is the inclusion of com-

pletely independent A/D and D/A sections. Three distinct oper-

ating modes allow them to be used separately and in combina-

tion in several ways

(see the block diagram opposite)

. The A/D

and D/A sections of the PSX-100 may be clocked separately and

can be configured to work together in different ways. The digi-

tal inputs and the A/D output are fed into a routing section

which sends signals to the D/A and Aux output and/or to the

main digital outputs, according to which of the three basic oper-

ating modes is selected.

The default is Confidence Monitor mode, in which the A/D

and D/A are independently clocked (and can even run at differ-

ent sample rates). The output of the A/D is available at all the

digital outputs, and the D/A can receive its signal from any of the

available digital inputs. The bargraph metering can be switched

between A/D and D/A. In this mode, there are two separate sig-

nal paths through the unit, while the other modes utilize a single

path.

Digital Copy mode takes the selected digital input and pro-

vides it to all the PSX-100's outputs, digital and analog. Both

clocks in this mode are synchronized to the digital input. This

mode is ideal for format conversion, and simply copying digital

media without having to re-patch your system.

In Analog Monitor mode, the A/D is fed to all the system out-

puts and to the D/A, which therefore monitors signals passing

through the A/D. The main clock is used as the reference (locked

to crystal or an external source), while the auxiliary clock is

slaved to it.

High sample rates,

high resolution, high quality

To summarize, the PSX-100 is Apogee’s first high

density, high resolution converter, offering 24-bit

A/D and D/A conversion at 88.2 and 96 kHz in

addition to conventional sample rates. This makes

the system ideal for stereo DVD and DVD-Audio mastering and as

a front-end to high-resolution, high sample-rate editing systems,

digital audio workstations and master recorders.

Exclusive self-balancing analog I/O; two

patented Apogee Low-Jitter Clocks; and

exceptional attention to detail in both the

analog and digital aspects of the PSX-100 combine to make it

capable of the finest audio performance available today. Once

again, Apogee represents the heart of digital audio – and the

heart of your system.

High resolution. Apogee quality.
