Lexicon Studio User Guide Addendum

System Requirements

The following system is recommended as the minimum for working with Lexicon Studio and
Steinberg Cubase Audio VST:

• 200 MHz Pentium Processor or compatible equivalent is the new minimum requirement
set by Cubase Audio VST (Intel processors are also highly recommended.)

• 64 MB of RAM

• Audio-capable disk drive

• Microsoft Windows – 95™ or later

Versions of Windows

Your printed manual contains out-of-date information regarding the compatibility of Lexicon
Studio with Windows 95. Lexicon Studio will work with any version of Windows 95 from
Windows 95 V.0 (the first release of Windows 95) or later.

High Performance Systems

Popular software packages like Cubase VST, Logic Audio, and Digital Performer all show
performance improvements with high CPU speeds and additional RAM. A high performance
system benefits from the following:

• Fast CPU – Intel is the best choice. CPUs from other manufacturers often don’t perform
as well at the same rated clock speeds and may have variant implementations of
important sections like the FPU (Floating Point Unit).

• A system “boot” drive and a separate drive for audio.

• A reliable video card with current drivers. Some cards offer acceleration done in such a

way as to “hog” the PCI bus and create digital logjams. A computer offering AGP
(Advanced Graphics Port) capability for the graphics card is preferable as it gets the
video off the PCI bus.

SCSI Vs. IDE

Both SCSI and IDE offer distinct advantages:

Benefits Liabilities

SCSI fast bus performance, removable

media, lots of choices of high
performance drives

Use of a PCI card to interface to the
computer increases bus traffic

IDE drives approach SCSI

performance, inexpensive, using
the IDE bus decreases activity on
the SCSI bus

A system that uses SCSI (PCI) for audio I/O transfers, and IDE for data transfers to and from
the hard drive, and an AGP port for graphics traffic wins the performance test. Adding a
SCSI card and removable media to transport jobs (copying them to and from the internal
IDE drive) wins on performance with the current available technology. Stay tuned on our
Website for the latest recommendations as technology changes.

the IDE bus is slower (in most cases
this is NOT the limiting factor), fewer
model choices, no removable media

II. Installation

Depending upon your computer, installation of your Lexicon Studio system should take
about 20 minutes. Please read through the entire procedure before performing the
installation. Lexicon Studio works with third party software (as with Steinberg Cubase VST).
You should complete installation of this software prior to installing the hardware and
software for Lexicon Studio. Refer to your audio software user manual on how to
accomplish this.

Precautions

• Turn off and unplug your computer.

• Use the anti-static wrist strap provided with your system and make sure that you are

grounded during the entire installation process to prevent static charges that can
damage components.

• Put the anti-static bags containing your cards near your computer to avoid walking
around with a card after it is removed from its bag (and generating static electricity).

• Before handling any Lexicon Studio cards, discharge any personal static electricity that
may be on your clothes or body by touching a grounded metal surface, such as the
power supply case inside your computer.

• Handle the cards only by their edges, as you would a CD. Avoid touching the pins on the
bottom edge of the cards.

• Save the anti-static bags containing your Core-32 System card and PC-90 module.
These prevent static electricity from damaging sensitive electronic components on the
cards. Whenever cards are removed from your computer, they should be stored in these
bags.

Hardware Installation

Windows will automatically detect and recognize your Lexicon Studio hardware once
installed and allowed to restart. Windows 95 will also prompt you to install drivers at this
point. Some of the Lexicon Studio software is installed within directories of your audio
control software (such as Cubase Audio VST). You should install your audio software first
and verify that it launches properly before installing Lexicon Studio (even though it will not
be audio-capable until installation of the Lexicon Studio system). Please refer to your audio
software manual for details on installation, and then continue the Lexicon Studio hardware
and software installation.

Setup

1. Put on the anti-static wrist strap.

2. Place the foam from your Lexicon Studio package on top of a work surface next to your
computer. (Any piece of static-safe foam with similar dimensions to the Core-32 card can
be used).

3. Make sure that your computer is properly shut down and unplugged.

4. Remove the computer top cover and PCI slot cover(s) for the slot(s) that you’ve chosen
for your Core-32 cards. If you do not know how to open your computer, consult your
computer's owner manual.

5. Touch the computer power supply case to discharge any personal static electricity.

6. Remove the Core-32 card from its anti-static bag, holding the card only by its edges. Be
careful to avoid touching the pins on the bottom edge of the card. Place the Core-32 bag
on top of the foam and place the card on the foam with the white PC-90 connector facing
up as shown below.

Mount the PC-90 card onto the Core-32 card

The PC-90 module can only be mounted onto a Lexicon Studio Core-32 system card.
Attempting to attach your PC-90 to any other type of PCI card may damage your PC-90
module.

1. Touch the computer power supply case to discharge any personal static electricity.

2. Remove the PC-90 module from its anti-static bag, holding the card only by its edges.
Place the bag on your work surface next to your computer and place the PC-90 on it with
its white connector facing up.

3. Pick up the PC-90 card and orient it so that the connector side faces away from the palm
of your hand.

4.

Lexicon Studio User Guide Addendum

4. Pick up the Core-32 in your other hand. Orient the cards with their connector sides facing
each other and align the connectors at the top of each card. Firmly press the cards
together until they connect fully. The holes on the edges of the Core-32 card should be
aligned with the standoffs on the PC-90 card.

5. Once the cards are mated, place the assembly, with the Core-32 card on top, onto the
Core-32 anti-static bag. Use the four screws provided to attach the PC-90 to the Core-32
card. Do not overtighten the screws as you may damage the boards.

Attach the PCI Extender

The extender provides support for cards installed horizontally and prevents boards from
touching one another and shorting. To attach the extender:

1. Holding the Core-32 assembly by its edges, align the holes of the board and the
extender.

2. Insert two screws (provided) from the back of the Core-32 card as shown. Do not
overtighten the screws , as you may damage the Core-32 card.

Install the Core-32/PC-90 assembly

The Core-32 System card must be installed in a full-size PCI slot which is a bus master slot.
Refer to your computer owner’s manual to determine which slots are available as bus
masters. (On some older motherboards, the PCI slot next to the ISA bus connector [the
PCI/ISA/ shared slot] in not a PCI bus master slot).

1. Touch the computer power supply case to discharge any personal static electricity.

2. Pick up the Core-32/PC-90 assembly by the top of the metal bracket and the top of the
other end of the card.

3. Align the card assembly over the slot you’ve chosen and insert it.

4. Place one hand along the upper edge of the card and push down firmly until the card is
fully seated in the slot. Do not use excessive force.

5. Once the card is fully seated, attach the Core-32 bracket to the computer chassis with the
screw provided with your computer. If you are standing the computer up, check to see

5.

Lexicon Studio User Guide Addendum

that the boards are not bending and shorting against each other. If they are, you will
need to install the PCI Extender (see previous section).

6. Replace the cover on the computer. Do not operate the system without the

cover.

Connect the LDI-12T Interface to Audio Sources

Cables/Connections

1. Use only the proprietary Lexicon cable (provided) to connect the Core-32 card to the
LDI-12T Interface.

2. With both the computer and the LDI-12T powered down, attach the cable between the
lower connector on the back of the Core-32 card and the Computer port on the LDI-12T
rear panel.

3. Connect the 9V connector to the AC Power port on the rear panel of the LDI-12T, and
plug the other end into a wall socket.

The LDI-12T supports various formats of analog and digital I/O. Make certain your cables
are the correct types prior to connection. (Analog XLR connectors are +4dBu balanced [Pin
2 hot], analog RCA connectors are -10dBV unbalanced). To select a source for input or
output within the application software, refer to the documentation provided with your
particular software package.

Software Installation

Install Supported Third Party Audio Software

Lexicon Studio requires compatible front-end software (such as Steinberg Cubase Audio
VST) to operate. Please refer to your particular software installation guide for assistance. As
Lexicon Studio installs software within directories of your front-end software, you should
install your audio software first (even prior to installing your Lexicon Studio hardware) and
verify that it launches properly before installing Lexicon Studio (even though it will not be
audio-capable until installation of the Lexicon Studio system).

Install the ASIO Lexicon Studio Driver for Windows 95

1. With your Lexicon hardware and Cubase VST software installed, power up your
computer and your LDI-12T interface. Once your computer is fully booted, Windows 95
will identify your Core-32 as a new PCI multimedia device (in the event of booting
problems, refer to the troubleshooting section of your Lexicon Studio manual).

2. Insert Lexicon Studio Software Disk 1: Studio Drivers, and click the Next > button.

3. Windows will find the driver information for the Lexicon Studio Sound System. Click
the Finish button to install the drivers.

4. Windows will prompt you to restart your computer once it is finished loading the drivers. If
you are also installing a PC-90, you should choose not to restart at this time and
continue by following the instructions for installing PC-90 software within the next
section. Windows will prompt you twice to restart. Select No at both prompts and move
on to the next section, Installing the PC-90 Software for Windows 95. If you are only
installing Core-32 drivers, you may now restart your machine.

III. Control Panels

New functionality has been added to the Studio Control Panels since the printing of the
manual. The information in the section is in addition to that which you will find in your
printed manual.

Control I/O

A Turbo Select feature has been added to the Control I/O panel. Turbo select allows you
to optimize audio playback and record on your system, in regards to the speed and
performance of your computer system. Older legacy machines do not have the processing
capability to play or record 32 streams of digital audio simultaneously without glitching.
Leaving the Turbo Select box unchecked will optimize these systems to have less
throughput channels, but higher quality audio. If you are experiencing pops and clicks, or
otherwise glitchy audio in a slower machine, you should uncheck this box. Note that with
Turbo Select off, you are limited to 24 streams of digital audio at 44.1 kHz sample rate and
21 at 48 kHz sample rate.

If your computer system is fairly new (Pentium II, 266 MHz or higher), you should engage
Turbo Select to get optimum performance out of your Lexicon Studio. The default setting for
Turbo Select is off. Off is the recommended setting for Pentium I 200 mHz machines or
slower.
