Lexicon Studio V4.20 User Guide for Macintosh and PC

Introduction

Thank you for your purchase of a Lexicon Studio system. Lexicon Studio is a line of professional hardware components designed for your computer that provides uncompromised audio quality and extensive processing capability. This family of products is designed to allow you to tailor your working environment to your needs. Lexicon Studio provides I/O options, DSP, signal routing, and synchro­nization for industry leading software.
Although written to accommodate both novice and expert users, this manual assumes some familiarity with the software application you have selected to interface with Lexicon Studio. If you have questions concerning the use of your software application, please refer to the user manual provided by the manufacturer of the software before using your Lexicon Studio system.
This manual is designed for both the Macintosh and PC versions of Lexicon Studio, which differ only in installation procedures. As pictures from both platforms are used throughout this manual, your screen graphics will vary depending on the system you are using.
Getting Started
1
Getting Started
Electronic PDF documentation containing late-breaking information is provided on CD-ROM with your Lexicon Studio system, along with electronic documentation for the PC-90. These PDFs have information that may be crucial to operating the latest version of the software you are using. The electronic documentation always supersedes the information in your printed manual. Please read it carefully, and always look to our website at www.lexicon.com for the latest updates in both software and documentation.

Getting Started

System Requirements

The following systems are recommended as the minimum for working with Lexicon Studio:
Macintosh
• 200MHz PowerPC processor (PowerPC 750 G3 processors are highly recommended)
• 64MB of RAM
• Audio-capable disk drive
• MacOS 7.6.1 or later
PC
• 200MHz Pentium Processor or compatible equivalent (Intel processors are also highly recom­mended.)
• 64MB of RAM
• Audio-capable disk drive
• Microsoft Windows — 95™, 98™ or later

High Performance Systems

Popular software packages like Cubase VST, Logic Audio and VisionDSP all show performance improvements with high CPU speeds and additional RAM. A high performance system benefits from the following:
• Fast CPU — For the best Macintosh performance, use a G3 processor. Intel is the best PC 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 that “hog” the PCI bus and creates data logjams. For Macintosh, use on-board video or an Apple-approved video card.
• AGP (Advanced Graphic Port) capability for the graphics card is preferable as it gets the video off of the PC's PCI bus.

SCSI Vs. IDE

Both SCSI and IDE offer distinct advantages and disadvantages:
Benefits Liabilities
SCSI • Fast bus performance • Use of a PCI card to interface
• Removable media to the computer increases bus
• Choice of many high traffic, especially if multiple PCI performance drives cards are in the system
IDE: • Drives approach SCSI • The IDE bus is slower (in most
performance cases this is NOT the limiting factor)
• Inexpensive • Fewer model choices
• Using the IDE bus decreases • Limited removable media activity on the SCSI bus
For both Macintosh and PC systems it is always best to dedicate one disk drive for the operating system, and a second drive specifically for audio.
Stay tuned on our website for the latest recommendations as technology changes.

Depending on 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 (such as Steinberg Cubase VST, Opcode VisionDSP, Emagic Logic Audio) which should be installed 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
• Put the anti-static bags containing your cards near your computer to avoid walking around with
• Before handling any Lexicon Studio cards, discharge any personal static electricity that may be
• Handle the cards only by their edges, as you would a CD. Avoid touching the pins on the bottom
• Save the anti-static bags containing your Lexicon audio card and PC-90 module. These prevent

Hardware Installation

As some Lexicon Studio software is installed into directories of your audio control software (such as Cubase Audio VST), you should install and verify that your audio software 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 proceed with Lexicon Studio hardware and software installation.
Your Lexicon Studio system may contain either of two versions of the Core-32 audio card. The installation procedure is identical for both cards.

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 flat piece of static-safe foam with similar dimensions to the card can be used.)
3. Make sure that you computer is properly shut down and unplugged.
4. Remove the computer top cover and PCI slot cover(s) for the slots you’ve chosen for your Lexicon Studio cards. If you do not know how to open your computer, consult the manufacturer’s owner’s manual.
5. Touch the computer power supply case to discharge any personal static electricity.
6. Remove the 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 anti-static bag on top of the foam and place the card on the foam with the white PC-90 connector facing up.

Mount the PC-90 card onto the Audio card

The PC-90 module can only be mounted onto a Lexicon Studio Core-32 audio 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.
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. Pick up the audio card 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 audio card should be aligned with the standoffs on the PC-90 card.
5. Once the cards are mated, place the assembly, with the audio card on top, onto the anti-static bag. Use the four screws provided to attach the PC-90 to the audio card. Do not overtighten the screws, as you may damage the PC board.

Attach the PCI Extender

The extender provides support for cards installed horizontally and prevents boards from touching each other (which can damage the cards). To attach the extender:
1. Holding the card assembly by its edges, align the holes of the board and the extender.
2. Insert two screws (provided) from the back of the card as shown. Do not overtighten the screws, as you may damage the PC board.
NOTE: On most new Macintosh models, the PCI bus is sized to fit full-length PCI cards solidly. On these models (9600, G3 Mini-tower) you will not need to install the PCI Extender.
Lexicon

Install the Card assembly

The audio card must be installed in a full-size PCI slot which is a bus master slot to take advantage of its bus master capabilities. 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] is not a PCI bus master slot).
1. Verify that third party audio software is installed and launches correctly.
2. Touch the computer power supply case to discharge personal static.
3. Pick up the card assembly by the top of the metal bracket and the top of the other end of the card.
4. Align the card assembly over the slot you’ve chosen and insert it.
5. Place one hand along the top edge of the card and push down firmly until the card is fully seated in the slot. Do not use excessive force.
6. Once the card is fully seated, attach the bracket to the computer chassis with the screws provided with your computer. If the computer is a tower or mini-tower design, check to see that boards are not bending under their own weight and shorting against each other.
7. Replace the cover on the computer. Do not operate the system without the cover.

Signal Routing

Using Cubase VST as an example of a host application, the following things determine signal routing.
1. Interface (LDI-12T/LDI-10T) connections.
2. Configuration of the Core-32 Control Panel 12T tab and Routing tab.
3. Inputs and outputs selected and enabled in Cubase Audio VST. Typically, all connections enabled in the Routing tab will appear directly in the application as available
inputs and outputs along with the Core-32 Control Panel routing for the PC-90 and Punch Record. Details on these are covered in the following section.

Core-32 Control Panel

Certain portions of the Lexicon Studio System should be specifically set up for the program you are using. This setup is performed in the Core-32 Control Panel. To access the Control Panel, pull down the Audio menu, select System and click on the ASIO Control Panel button. Our example is from Cubase VST. The actual procedure will vary depending on your audio application.
