Outdoor Antenna Grounding
Ifan outsideantenna isconnected tothe receiver,be surethe antennasystem isgrounded soas toprovide
some protection against voltage surges and built-up static charges. Section 810 of the National Electrical
Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna-discharge unit, size of grounding
conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for
the grounding electrode. See figure below.
Power Lines An outside antenna should be located away from power lines.

Installation
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 and generating static electricity after it is removed from its bag.
• 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.
• Handlethe cards only by theiredges, as youwould aCD. Avoid touchingthe pinson the bottom
edge of the cards.
• Savethe anti-staticbag containingyour Lexiconaudio card.This prevents static electricity from
damaging sensitive electronic components on the card.

Cables/Connections
1. Use only the proprietary Lexicon cable (provided) to connect the Core2 card to the Lexicon
Core2 connector box.
2. With the computer powered down, attach the cable between the connector on the back of the
Core2 card and the Computer port on the connector box.
3. Connect your external audio devices to the connector box, or to the optical connectors on the
Core2 card itself.
Theconnectorboxhousesfourunbalanced1/4"analoginputsandeightunbalanced1/4"analog
outputs, as well as a coaxial S/PDIF input and output. The coaxial input can also be used as a
Word Clock input. (See Chapter 3.)
The back plate of the Core2 card carries the optical connectors. These can be configured (via
the Control Panel) to accept either ADAT™ or S/PDIF formats.
The Core2 can run in a variety of modes which affect the number and type of available I/O. These
operating modes are described in detail in Chapter 3: Core2 Basics.

Software Installation
Install Supported Third Party Audio Software
The Core2 requires compatible front-end software (such as Syntrillium Software's Cool Edit Pro) 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 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).
IfyouareinstallingalaterversionofLexiconStudiosoftwareoveryourcurrentStudiosoftware,please
skip to the next section entitled Updating Drivers.
Install the Lexicon Studio Driver for Windows
1. With your Lexicon Studio hardware and third party audio software installed, power up your
computer. Once your computer is fully booted, Windows will identify your Core2 as a new PCI
multimedia device. In the event of booting problems, refer to the troubleshooting section of this
user guide.

Analog Input Levels
The level of the Analog Inputs can be controlled by on-screen faders with the level displayed
numerically at the bottom. A level setting of 0dB sets unity gain from the analog input to the analog
output. A setting of 0dB corresponds to -10dBV, 18dB below digital full-scale.

the same level.
Control click on the Link button to link the fader heads while maintaining their relative levels.
Control click on a fader head to set the fader (or linked fader pair) to 0dB.
To enter gain levels numerically, double-click on a numeric field, then enter a value.

Saturation Emulation (TSE™). Type IV enhances the dynamic range of A/D converters by providing
alogarithmic“TypeIVOverRegion”thatextendstheuseabledynamicrangebeyondthelinearrange.
TSE captures the sound of an analog tape machine in the saturation region.

2. Move the desired jumper to the “out” position. (The jumper nearest the edge of the card is for
Analog Input 1.)
3. Replace the Core2 card in the computer, reboot, and launch the Lexicon Control Panel. The
corresponding LED under the Type IV logo should be off (indicating that Type IV is inactive on
this channel).
Punch Tab
This page lets you select input Sources for Punch or overdub recording and output monitor
Destinations for the sources selected for Punch or overdub recording. The Punch feature lets you
performoverduborpunchrecordingbydirectlyconnectingtoaLexiconStudiointerface—noexternal
mixer is required.
All computer operating systems have a delay when applications use host processing. The delay will
vary depending on the buffer size of the audio hardware. This means that, when playing along with
previouslyrecordedtracks,thetrackyouareplayingwillsounddelayedwhileyouareperforming.This
delay can be overcome by using an external mixer, or by using the Punch feature.

Using the LexPanel

Lexicon
The punch feature mixes the input signals directly with the outputs selected for your monitor system
(speakers or headphones) to avoid the inherent processing delay from the card to the computer
application and back.
Unlike monitoring through a tape deck where the input is typically monitored when the transport is in
Stop or Record and muted during Play, the input signal is monitored all the time .
Configuring the Punch feature
1. Select Enable Punch to turn on monitoring.
2. Select as many input sources as you like, clicking multiple selections with the shift or Ctrl key.
Note that only those I/O selections which are currently enabled in the Routing tab will appear as
Source and Destination selections.
3. Select the outputs you are using for monitoring. (Often the analog left and right outputs will be
connected to an amp and speakers — digital connection to a mixer is, of course, also possible.)
A mono mix of the selected inputs will be sent to the outputs.
4. If you are using Cubase, select Global Disable from the System Setup dialog to turn off the
monitoring through the application so that a delay is not heard from the input signal.
The MIX Level Control
MixLevel allowsyoutoadjustthevolumeoftheselectedPunchsourcesthataremixedwiththeVST
output assigned to the same outputs (usually “Master”).
NOTE: If multiple sources are being summed, the Mix Level may need to be lowered to avoid
distortion. In such cases, try an initial setting of 40.
