Introduction – all products
Installation – all products
Installation
Complete installation consists of disabling Windows system sounds, deciding
which Echo driver you are going to use, installing the Windows drivers into your
system, installing the PCI or CardBus card, connecting the audio interface to the
card (Layla24 and Gina24) and, if necessary, installing a multitrack audio
recording/editing application.
System Sounds
We suggest that you turn off your Windows system sounds prior to installing your
Echo product. Because most system sounds are sampled at very low sample rates,
typically 11 to 22 KHz, each time they are played it will cause the sample rate
clock on your Echo product to reset to the slower speed.
To turn off the system sounds, first go to the Windows “Control Panel,” which can
be found under “Settings” from the “Start” button. On the control panel you will
find an icon titled “Sounds” or “Sounds and Multimedia”. After double clicking
on this icon, you will see a window labeled “Schemes” near the bottom of the
screen. Click on the small down arrow to the right of the combo-box, and select
the “No Sounds” option. Then, click on the Ok button.
VxD vs. WDM - Deciding Which Driver to Install
VxD and WDM are two different driver architectures for Windows. You only
have a choice between the two if you are using Windows Me. If you are using
Windows 98, you must use the VxD drivers. If you are using Windows 2000 or
XP you must use the WDM drivers.
For Windows Me you should use the VxD drivers, unless you fall under one or
both of the following two categories:
1) You are using an audio program such as Cakewalk’s SONAR, which takes
advantage of the WDM architecture to achieve low latencies.
12
Installation – all products
Installation – all products
2) You are using an audio program that uses an ASIO driver. In general, the
WDM ASIO driver provides higher performance than the VxD ASIO driver.
For a detailed discussion of the benefits and drawbacks of the WDM architecture,
please read Appendix F: WDM-Windows Driver Model FAQ.
Installing the PCI Card for Desktop Computers
Once you have verified that there are no problems with your system, it is time to
install the Echo PCI card into your computer.
1. Install the drivers. You should do this before inserting the PCI card. Insert
the Echo Install CD-ROM into your machine. The Main Install Window should
automatically appear; if it does not, simply go to “My Computer,” and doubleclick on your CD-ROM drive icon. Now, select “Install Windows Drivers,”
and follow the on-screen directions.
2. Once you have installed the appropriate driver for your version of Windows,
turn your computer off.
IMPORTANT - Unplug your computer and detach all peripherals before
proceeding with the following steps.
3. Remove your computer’s cover. This operation differs from computer to
computer. Refer to your computer’s manual for a further explanation of this step
if necessary.
4. Select the PCI slot into which you will install the card. You may use any
available PCI slot in your computer for the card. Unscrew and remove the
bracket covering the expansion slot where you would like to install your Echo
product. Put the screw in a safe place, as you will need it later to complete the
installation.
5. Insure that you have fully discharged all static electricity from your body
before handling the card. This can be done through the use of a grounding strap
13
Installation – all products
Installation – all products
or, more simply, by touching your bare hand to the metal casing of the
computer’s power supply. (For this latter method to work, the computer must be
plugged in, though not turned on.) After you’ve discharged your static, unplug
the computer before proceeding to the next step.
6. Remove the card from its protective anti-static bag. Handle the card carefully by
its edges, and insert it into the selected expansion slot. Insure that the card’s
edge connector (the protruding edge with the gold leads) is seated firmly into the
slot. Centering the card over the slot and using a gentle rocking motion while
pushing downward into the slot generally works well. Be careful not to force the
card into the slot, or bend or twist it while it is being inserted, as this could result
in the card being damaged.
7. Now use the screw that you removed earlier, from the protective back plate, to
attach the metal bracket on the card to the computer’s rear panel.
8. OPTIONAL: (If you have Mia or MiaMIDI, skip this step.) An Esync cable
comes with Gina24, and can be used to daisy chain several 24-bit Echo cards
together. Esync is a proprietary form of super clock that allows you to sync
together multiple 24-bit Echo products. Simply attach the Esync cable to the
two-prong “Esync Out” connector on the Layla24/Gina24 PCI card, and attach
the other end to the “Esync In” connector on your Gina24 PCI card.
9. Replace the computer’s cover, and secure it. Reattach its power supply cord
and reconnect any peripherals that you may have removed prior to beginning the
installation.
10. (Layla24 and Gina24 only) Locate the audio interface box (Layla24 and
Gina24), the interface cable, and the power cable. Securely mount the interface
into your equipment rack (Layla24 only). If you will not be mounting the box in
a rack, remove the backing from the four rubber feet and place one in each
bottom corner of the interface unit. Then be sure to locate the rack-mount box in
a secure location.
Plug one end of the cable into the connector on the Echo PCI card that now
protrudes through the back panel of your computer, and secure the cable using
the built-in screws located on both sides of the connector. Attach the other end
14
Installation – all products
Installation – all products
of the cable to the connector on the rear of the interface labeled computer and
fasten the cable securely with the screws. Plug the power cable firmly into the
interface and a power socket, but do not turn on the interface at this time
(Layla24 only).
Caution: Never connect the rack-mount interface to the computer while either
the interface or your computer is turned on.
11. (MiaMIDI only) Now that MiaMIDI is plugged into your computer, you will
need to connect the MIDI-S/PDIF breakout cable to the back of the MiaMIDI
card. Take the breakout cable and plug it into the 7-pin DIN connector labeled
MIDI S/PDIF at the bottom of the PCI card bracket.
12. You can now attach external audio devices to the connectors. Information on
attaching external devices to your particular interface may be found in the
following sections.
13. (Layla24 only) Turn on your Layla24 audio interface box.
14. Turn on your computer. Once Windows starts, it should find new hardware
and begin to install the drivers. For most versions of Windows, this process is
entirely automatic. For Windows XP, you should select the option “Install the
software automatically,” and follow the on-screen directions.
Note: This version of the WDM driver has not been digitally signed by
Microsoft; for Windows 2000 and XP, you will need to confirm that you
want to install an unsigned driver.

Installing the CardBus Adapter for Laptop Computers
Once you have verified that there are no problems with your system, it is time to
install Layla24 LapTop into your laptop computer.
1. Install the drivers. You should do this before inserting the CardBus Adapter.
Insert the Echo Install CD-ROM into your machine. The Main Install Window
should automatically appear; if it does not, simply go to My Computer and
double-click on your CD-Rom drive. Now, select “Install Windows Drivers,”
and follow the on-screen directions.
2. Once you have installed the appropriate driver for your version of Windows,
turn your computer off.
3. Locate the rack-mount interface, the 9-pin interface cable, and the power cable.
Securely mount the interface into your equipment rack. If you will not be
mounting the box in a rack, remove the backing from the four rubber feet and
place one in each bottom corner of the interface unit. Then be sure to locate the
rack-mount box in a secure location.
4. Connect the cable. Before installing the card into the computer, connect the
cable between the card and the rack-mount chassis. Make sure the cable is fully
inserted into the card and that it “clicks” into place. You may have to wiggle it
a bit for this to happen.
5. Insert the LapTop adapter into your computer. Make sure the computer is
turned off. To install the card, insert it into any available CardBus slot. Next,
turn on the audio interface box.
6. Turn on your computer. Once Windows starts, it should find new hardware
and begin to install the drivers. For most versions of Windows, this process is
entirely automatic. For Windows XP, you should select the option “Install the
software automatically,” and follow the on-screen directions.
16
Installation – all products
Installation – all products
Note: this version of the WDM driver has not been digitally signed by
Microsoft; for Windows 2000 and XP, you will need to confirm that you
want to install an unsigned driver.
Once the driver is installed, a small “PCCard” icon will appear in the system “tray”
(usually on the lower right-hand side of the screen).
While it is possible to “hot-dock” the card by inserting it with the laptop powered
up, it is recommended the card only be inserted or removed with the power off. If
you have to remove the card with your computer turned on, the card must first be
disabled. To do this, click on the PCCard icon in the tray, and tell Windows to
stop the card. You will get a message when it is safe to remove it. Failure to
disable the card before removing it could potentially damage the card or the
computer.

Audio connections – Layla24
Connecting to Layla24’s Rack-mount Audio Interface
The back panel of Layla24’s rack-mount audio interface contains a wide variety of
connections that allow great flexibility in the operation of Layla24. For optimal
performance with Layla24, it is critical to use the appropriate cabling and
connectors.
Analog Inputs and Outputs
Layla24 has eight analog inputs and eight analog outputs on the rear panel. The
input and output connections can accept unbalanced or balanced signals via ¼”
connectors. By default, the inputs and outputs are set to receive or send a +4 dBu
signal. You can also select –10 dBV for each individual input and output (see the
description of the console, below).
Layla24’s front panel has a ¼” headphone output jack with a corresponding
volume knob which monitors analog outputs 1 and 2.
18
Audio connections – Layla24

The Computer Connector
Next to the analog inputs and outputs is a connector labeled COMPUTER. This
connector is known as a DB-9, and is similar to the serial port on a PC. It is the
point at which the audio interface connects to the Layla24 PCI card inside your
computer.
A cable was supplied with your Layla24 for this purpose. This custom made cable
is manufactured to certain specifications; if you need to replace it, you should only
use a replacement cable from Echo.
ADAT / S/PDIF Optical I/O
Next to the COMPUTER connector is a pair of connectors labeled OPTICAL, IN
and OUT. These connectors are used to transmit digital audio data among via an
optical signal.
You can use this port for ADAT (8 channels) or for optical S/PDIF (stereo) I/O.
Note: Layla24 is only capable of transmitting or receiving one type of
digital signal at a time. You must choose either ADAT optical or S/PDIF
(optical or RCA); you cannot use both simultaneously. The Digital Mode
Switch can be found in the Layla24 Console. For more information, refer to
