With the introduction of the world’s first
digital processor in 1971, Lexicon became
the world leader in digital audio. Since that
time, Lexicon has continuously
introduced ground-breaking tech-
nology to the audio industry.
Today, Lexicon processing is heard
on over 80% of all recordings,
broadcast and film soundtracks
and, in the home theater market,
Lexicon sound is the acknowl-
edged measure of excellence.
The Lexicon Studio line of
products continues this tradition of innovation
with a new generation of production tools:
high-qualityanalogconversion,digital connectivity,
format conversion, signal routing,
synchronization, system accelera-
tion and audio DSP — hardware
solutions that work with your
favorite software.
Focused on the fundamentals —
superb sound and flawless DSP,
the Lexicon Studio line is designed
to power your computer system
into the future.

Dual Stereo (Parallel), Cascade,
Mono Split and Dual Mono
•Effects include: Chorus, Flange,
Pitch, Detune, Delay, Echo, Rotary,
Tremolo, Reverb and Ambience

Desktop audio production requires
computing power. Semi-pro cards not
only sacrifice audio quality, they
consume the power your CPU needs for optimal
performance — leaving you with a power-starved
computer that can’t keep up with the demands of
professional recording. Lexicon Studio hardware
solves this problem by taking over the most CPU-
intensive tasks — giving you superior audio and
more processing power. Whether you’re just
getting started, or investing in a system that will
grow along with your production needs, Lexicon
Studio offers the I/O you need and the audio
quality you can only get from Lexicon.

Core-32
The Core-32 is an expandable hard-
disk recording system on a full-size PCI
card. It has a full 24-bit audio path,
capable of supporting up to 32 simulta-
neous voices as sources or destinations
from the host system – with the I/O to
do it the way you want. Select the
LDI-12T and/or up to three LDI-10T
interfaces, and an effects card that
brings the classic PCM 90 reverbs to
your desktop.
LDI-12T
The LDI-12T interface provides
superior A/D conversion at both
professional and consumer input levels.
TOSLINK™optical input and output
connections for any ADAT™-compati-
ble device provide eight channels of
digital I/O. ADAT sync connectors
ensure accurate system clocking,
synchronization and machine control.
A pair of coaxial RCA connectors
provide two channels of S/PDIF
digital I/O.
The TOSLINK connectors can also
be used for S/PDIF connections which
require an optical I/O, allowing simul-
taneous format conversion between,
for example, two DATs, one with
coaxial (RCA) and one with optical
connections.
XLR balanced Time Code inputs,
in conjunction with the Core-32
on-board variable oscillator (VSO),
lock to incoming Time Code and
maintain sync. A dedicated BNC input
allows clock synchronization to popular
digital mixers.
S/PDIF or ADAT connections can
be used for either clock master or slave.
A 9-pin connector on the rear panel lets
you connect to video and audio devices
capable of Sony 9-pin serial control.
LDI-10T
The LDI-10T interface features ten
simultaneous input/output channels:
eight analog (TRS balanced 1/4") and
two digital S/PDIF (Coaxial); switch-
able input gain; 24-bit A/D and
D/A conversion and a 1/4" Time
Code Input.
An optional LX3 allows connection
of as many as three LDI-10Ts, for 24
analog and 6 S/PDIF channels —
all from a single Core-32 card.
Run more tracks, more plug-ins AND the world’s best reverb and effects —
all without impacting your computer’s performance
Core-32 Desktop Audio System
Core-32 •LDI-12T •LDI-10T •LX3 •PC-90
Core2
The Core2 system provides connections for four
channels of analog in, eight channels of analog out,
eight channels of ADAT™digital I/O, and a stereo
S/PDIF pair. TOSLINK connectors (mounted
directly on the Core2 card) can also be used for
S/PDIF connections which require an optical I/O,
allowing simultaneous format conversion between,
for example, two DATs, one with coaxial (RCA)
and one with optical connections.
Beyond powerful I/O, audio performance is
the highest quality, with ultra wide-range 24-bit
A/D and D/A converters with selectable dbx
Type IV™soft-knee limiting on every input
channel to simulate tape compression and provide
4dB of improved headroom.
MP-100
The MP-100 incorporates all of the effects and
controls from Lexicon’s MPX 100 Dual Channel
Effects Processor on a snap-on card. This option
gives you true stereo dual-channel processing with
hundreds of presets with classic reverb programs
such as Ambience, Plate, Chamber and Inverse,
as well as Tremolo, Rotary, Chorus, Flange, Pitch,
Detune, 5.7 second Delay and Echo. Dual-
channel processing gives you two independent
effects in a variety of configurations: Dual Stereo
(Parallel), Cascade, Mono Split and Dual Mono.
Complete, powerful and affordable
interfacing for your computer
Designed around the Core-32 PCI card, this system gives you I/O options, DSP signal routing and
synchronization for your software and world-class reverb – without burdening computer performance
PC-90
The PC-90 Reverb Card uses the
core processing engine of Lexicon’s
award-winning PCM 91 to add
uncompromised reverb and processing
power to the Core-32 system. This
option gives you two stereo hardware
reverbs with all of the sonic quality
you expect from Lexicon, controllable
from your software interface.
Five classic algorithms: Chamber,
Inverse, Room, Ambience and
Concert Hall can be loaded into either
of two reverb engines — each with its
own stereo in/stereo out routing. One
hundred presets exploit the full
dynamic power of the PC-90.
