System Requirements

In order to use Gina24 you’ll need the following:

• An IBM-PC or compatible computer with PCI architecture
expansion slots (version 2.1 PCI), a genuine Intel Pentium or faster
CPU, a motherboard with an Intel chipset, and minimum 64Mb
RAM (more highly recommended) running Windows 95 or
Windows 98

• A fast, high-capacity IDE or SCSI hard disk drive

• Peripheral audio equipment, such as a microphones, studio
monitors, musical instruments, mixer, etc.

Gina24 Installation

Complete Gina24 installation consists of performing a system check,
disabling Windows system sounds, installing the Gina24 PCI card,
connecting the audio interface to the card, installing the Gina24 Windows
drivers into your system and, if necessary, installing a multitrack audio
recording/editing application.

System Check

The first thing you should do is check the display settings for your
computer. The Gina24 Echo Console software requires a minimum
resolution of 800X600 with small fonts to display properly.

To check your display settings, go to the Windows

System Sounds

There is one final step to perform before installing the Gina24 hardware.
We suggest that you turn off your Windows system sounds prior to
installing Gina24. Because most system sounds are sampled at very low
sample rates, typically 8 to 11 KHz, each time they are played it will cause
the sample rate clock on Gina24 to reset to the slower speed.

To turn off the system sounds, first go to the Windows

Installing the Gina24 Hardware

Once you have verified that there are no problems with your system, it is
time to install Gina24 into your computer.

IMPORTANT - Unplug your computer and detach all peripherals before
proceeding with the following steps.

1. 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.

2. Select the PCI slot into which you will install the Gina24 card. Inside

your computer you will likely find two types of expansion slots, ISA and
PCI. The PCI slots will be shorter and have a higher connector pin
density than the ISA slots. You may use any of the available PCI slots in
your computer for Gina24. Unscrew and remove the bracket covering the
expansion slot where you would like to install Gina24. Put the screw in a
safe place, as you will need it later to complete the installation.

3. Insure that you have fully discharged all static electricity from your body

before handling the Gina24 card. This can be done through the use of a
grounding strap 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.

4. Remove the Gina24 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.

5. Use the screw removed earlier from the protective backplate to attach the

metal bracket at the back of the Gina24 card to the computer’s rear panel.

6. OPTIONAL:

skip this step.

If you don’t have a Darla24, Layla24 or Mona, you can

If you have a Darla24, Layla24, Mona or another Gina24,
this would be a good time to attach an Esy nc cable to the Gina24 PCI
card. Esync is a proprietary form of super clock that allows you to sync
together multiple 24-bit Echo products. Esync cables come with Darla24
and Gina24, and can be used to daisy chain several 24-bit Echo cards
together. Simply attach the Esync cable to the two prong “Esync Out”
connector on the Gina24 PCI card, and attach the other end to the “Esync
In” connector on your Darla24 or Gina24 PCI card. Likewise, you can
attach another Esync cable to the “Esync In” connector on the Gina24
PCI card, and attach the other end to the “Esync Out” on either Darla24,
Layla24, Mona or another Gina24.

7. OPTIONAL:

If you don’t have a CD-ROM drive with a functional digital

If you do, then now would be a good
time to connect the S/PDIF CD-ROM connector cable to the tw o prong
“Digital In” connector on the Gina24 PCI card. Now connect the other
end to the “Digital Output” on the back of your CD-ROM drive.

NOTE: Not all CD-ROM drives have a Digital output, and
some have one that is not functional. You must check with
the manufacturer of your CD-ROM drive to determine
whether it has a functional Digital output or not.

8. 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 Gina24 installation.

9. Locate the Gina24 audio interface box and the 25-pin interface cable.
Place the box near your computer in a convenient location on a level
surface. Plug one end of the cable into the 25-pin connector on the
Gina24 card that now protrudes through the back panel of your com puter,
and secure the cable using the built-in screws located on both sides of the
connector. Attach the other end of the cable to the rear of the interface
box and fasten the cable securely with the screws.

NOTE: The cable included with your Gina24 system is a
shielded audio cable that has been custom manufactured to

exacting standards. Use of any other cable, such as a
computer printer cable, will result in unacceptably high
crosstalk and noise, thereby substantially reducing the
system’s overall audio quality. Though similar to the cable
provided with Darla24 and the older Gina product, this
cable carries both analog and digital data.

It is not
compatible with any other Echo products and should only be
used with Gina24.

If longer cable lengths are required, the
correct approach is to extend the audio cables between the
Gina breakout box and your mixer/amplifier rather than
the cable between the breakout box and the PCI card.

not use any other cable with Gina24.

10. You can now attach external audio devices to the interface box. Gina24
can accommodate two analog input signals and can generate eight
independent analog output signals. In addition, Gina24 provides stereo
S/PDIF digital input and output via coaxial RCA or optical connectors,
and eight channels of ADAT optical I/O. The analog and digital inputs
and outputs on Gina24 are simultaneously active, except that the digital
mode must be set to either S/PDIF or ADAT.

the S/PDIF jacks on Gina24, do not use standard analog RCA audio
cables. For reliable S/PDIF operation, 75ohm coaxial video cables are
recommended).

10

Connecting to Gina24’s Audio Interface

The back panel of Gina24’s audio interface contains a wide variety of
connections that allow great flexibility in the operation of Gina24. To
achieve the optimal performance with Gina24, it is critical that the
appropriate cabling and connectors are used.

Analog Inputs and Outputs

Gina24 has two analog inputs and eight analog outputs on the front panel.
The input and output connections can accept balanced or unbalanced jacks
via ¼” connectors. Both the inputs and outputs are set to receive or send a
+4dBu (balanced) signal.

Gina24’s front panel also has a ¼” headphone output jack with a
corresponding volume knob which m onitors analog outputs 1 and 2.

11

The Computer Connector

On the back panel of the Gina24 audio interface box is a connector labeled

COMPUTER

. It is the point at which the audio interface connects to the

Gina24 PCI card inside your computer.

A cable was supplied with your Gina24 for this purpose. This custom made
cable is manufactured to certain specifications and, if necessary, should only
be replaced by a special Gina24 cable available only from Echo.

Please Note: The Gina24 cable is NOT interchangeable with Darla24 or
Gina (20-bit) cables.

Installing the Gina24 Software Drivers

Now that you have com pleted the hardware installation, you need to install
the software drivers that allow Gina24 to interact properly with Windows
95/98 and your audio recording application.

Turn on the power to your com puter’s CPU. After Windows 95/98 starts up,
it will automatically sense the newly installed Gina24 card and indicate, via
a pop-up Install Wizard window, that new hardwa re has been found. At this
point, you should insert the Gina24 CD-ROM disc.

If you are using the original version of Windows 95:

Within the Install Wizard window are several options. Select the option

18

The Echo Console

Included with your Gina24 is a “virtual control surface” application called
the Echo Console. Every time you start Windows y ou will see it flicker
across the screen as it loads. Then it will minimize itself to the taskbar. The
Console allows you to control the audio I/O and clocking functions of
Gina24, and it brings these controls to a single easy-to-use location. From
the console you can control the output levels, select synchronization clocks,
select the digital mode, and adjust input monitoring.

The Echo Console software was automatically installed at the same time
that you installed the Gina24 driver for Windows 95/98. If installation was
successful, you should see a red capital letter G in your Windows 95/98
taskbar (typically in the bottom right-hand corner of your screen). Double­clicking on the “G” will activate the console program. It should look like
this:

19

The console functions are grouped into three areas: inputs (in the upper left
corner), monitors (directly below the inputs that are being monitored), and
outputs (on the right hand side). The controls for a particular function/stereo
pair are then further grouped into a box that contains selection buttons,
faders, and other controls and displays as determined by the function.

Console Controls

Let’s take a look at the control surface. The input control area is located in
the upper left portion of the console surface. For each input device pair you
will find a pair of input meters.

20

Monitor Controls

Below the input channels are the input monitor controls. The input monitor
controls allow you to monitor the input signal via any of the available
outputs on your Gina24. Each input channel pair has a corresponding
monitor control pair directly below it on the console. At the top of each
monitor pair are radio buttons that allow you to selectively mute (M) or solo
(S) each channel. In the middle you will find a pair of faders that will allow
you to set the levels of the monitor signals. A t the bottom of the control area
there is a radio button that allows you to “gang” (G) the faders. Ganging the
faders ties them together so that they will maintain their relative placement
with regard to each other. Below each fader is its corresponding pan control.
In the default pan positions (see example below) the signal from input
1(left) will be monitored by output 1(left), and the signal from input 2(right)
will be monitored by output 2(right). Moving a pan control will determine
how much of the input signal is sent to each output channel in the selected
output pair. Both pan controls and faders can be reset to default by pressing

Ctrl

the

Instead of level meters, each monitor control has a series of numbered
buttons. These buttons allow you to select which output channel pair
controls are displayed, so you can adjust them.

button and left clicking on the control.

The monitors are one of the most powerful functions of the console. When
you are recording, these controls allow you to set the level at which each
input signal will be monitored at each of the outputs, independent of the
main output level control.

21

When setting a monitor level, you must first select the input that will be
monitored, and then select the output for which you will set the monitor
level. Selection of the input is really just a ma tter of using the correct
monitor control box. A monitor setting will always affect the input pair that
is directly above it. To set the monitor for inputs 1/2, for example, simply
go to the monitor control directly below inputs 1/2 and click on one of the
buttons found in the center of the control.

Let’s say you want to set the level at which input pair 1/2 is monitored for
each of the four stereo analog output pairs on Gina24. You would first find
the monitor control that corresponds to inputs 1/2 (the control on the far left,
directly below the input control for channels 1/2). Clicking on the button
within this box labeled “1” causes the control box to display the currently
selected levels at which inputs 1/2 are being monitored at outputs 1/2.
Clicking on the button labeled “3” would cause the control box to display
the currently selected levels at which inputs 1/2 were being monitored at
outputs 3/4. You can move through the remaining buttons, setting the level
at which inputs 1/2 are monitored at each of the four output pairs, as well as
the S/PDIF “D” and ADAT “A#” outputs. The console program remembers
any settings that you make, and all settings for all outputs are maintained
independently.

Note:

You cannot monitor the S/PDIF inputs through the AD AT outputs
and vice versa. This is because you can only use one digital m ode (S/PDIF
or ADAT) at any given time. For more information, please see the section

Digital Mode Switch

“

” later in this manual.

Remember that all of the monitor controls remain in effect even when
they’re not displayed. The degree of attenuation (or muting) of each level is
set by the monitor controls. T he console program constantly maintains a
level setting for each of the monitor paths it controls. Clicking on an output
selection button simply selects the settings that are displayed.

22

Output Controls

The right hand side of the console is dedicated to the controls for analog
output channels one through eight (an output meter pair is included for the
two S/PDIF output channels, but these levels are not adjustable). The output
controls mirror those found on the monitor controls (Gang, Mute, Solo, &
faders), except that there are no pan controls and you will find level me ters
in the middle area instead of the numbered buttons. Just like the monitor
controls, the output faders can be reset to default by pressing the
and left clicking on the fader.

Ctrl

button

Adjusting Record and Playback Levels

Gina24’s output volume adjustments are made in the digital domain. When
you lower a volume slider, you are actually decreasing the number of
available bits, thereby taking away from the potential dynamic range of the
system. T o avoid this, we suggest that whenever possible you leave the
output sliders set to their maximum positions, and perform any necessary
attenuation on your external mixer. When the Gina24 playback volume
controls are set to maximum and the input signal approaches the maximum
pre-clipping level, you can achieve the full 24-bit dynamic range of the
system.

23

Setting Clock Sources and Destinations

At the very bottom of the Console there are buttons that allow y ou to select
the synchronization clocks that are used by Gina24. T he console program
