Congratulations on your purchase of the ESI GIGAPORT HD+.
GIGAPORT HD+ is a USB audio interface, that provides 8 analog output channels and two
independent high quality stereo headphone outputs. It is very easy to use, small and powerful. With
our excellent driver support GIGAPORT HD+ works perfect with all current recording, DJ and
sequencer applications. The USB connection makes installation extremly simple.

2. Installation
2.1 System Recommendation
GIGAPORT HD+ is not simply a standard digital audio interface card, but a high-resolution device
capable of advanced processing of audio content. Even though GIGAPORT HD+ is built to have
low-CPU resource dependability, system specifications play a key part in the GIGAPORT HD+s
performance. Systems with more advanced components are generally recommended.
Minimum System Requirements
PC
- Intel Pentium II 300MHz CPU or comparable AMD CPU (or equivalent) – we recommend at
least a Pentium III CPU with 600 MHz
- Windows XP or Windows Vista / 7 (32- and 64-bit) operating system
- 1 available USB port
- at least 64MB RAM
- high quality audio software with ASIO support recommended
Mac
- Power Macintosh G3 or higher
- 1 available USB port
- at least 64MB RAM
- Mac OS X 10.4 or higher
2.2 Hardware Installation
GIGAPORT HD+ is simply connected to an available USB port of your computer. A separate
power supply is not required, as GIGAPORT HD+ is a USB powered device. Simply install the
hardware by plugging it into your computer with the supplied cable.

2.3 Driver Installation
After the connection of GIGAPORT HD+, the operating system automatically detects it as a new
hardware device. Modern operating systems like Windows XP, Windows Vista / 7 or Mac OS X
usually detect the hardware directly and are installing the correct USB audio drivers automatically.
You can use GIGAPORT HD+ already now in typical consumer audio applications that do not need
special professional ASIO driver support. Under Windows XP this could be for example programs

ESI GIGAPORT HD+

used for DVD playback or more simple DJ applications that don’t require ASIO. Under Mac OS X
this could be applications like Garageband. Please note that our special driver is also required if you
are using higher sample rates than 44.1kHz.
Installation under Windows XP
Unplug the device before you start the installer if it is already connected. Then launch setup.exe
from the GIGAPORT HD+/Windows folder of the included driver CD or from a download of a
recent driver from our website.
You will now see a dialog as shown on the left picture below. Click Next. You can define the target
directory for the installation now. Confirm it with Next.
The installer now informs you that the driver installation will start as shown on the left picture
below. Confirm this with Next. During the following process you will see a dialog box once or
several times that informs you that the driver software has not passed Windows Logo testing. Please
be assured that our drivers have been tested in various different ways and are OK to be used.
Confirm any such dialog with Continue Anyway.
You will now be prompted to connect the hardware on the next dialog that is shown below on the
left. Plug in GIGAPORT HD+. Do not click Next yet. During the driver installation, Windows

ESI GIGAPORT HD+

might again prompt you to confirm the Windows Logo testing dialog once or several times with
Continue Anway before the driver installation is finalized.
You can now finally click Next on the ESI GIGAPORT HD+ Audio Driver Setup dialog. The
installation is now finished. To confirm this, please check if the ESI icon is displayed in the taskbar
notification area as shown below. Sometimes a reboot is required.
If yes, the driver installation has been completed successfully.
Installation under Windows Vista / 7
Unplug the device before you start the installer if it is already connected. Then launch setup.exe
from the GIGAPORT HD+/Windows folder of the included driver CD or from a download of a
recent driver from our website.
When launching the installation, Windows Vista / 7 might prompt a security message. Make sure to
allow the installation. You will then see a dialog as shown on the left picture below. Click Next.
You can define the target directory for the installation now. Confirm it with Next.
The installer now informs you that the driver installation will start as shown on the left picture
below. Confirm this with Next. During the following process you might see a Windows Security

ESI GIGAPORT HD+

dialog box once or several times that asks you for confirmation to install the driver software.
Confirm any such dialog with Install.
You will now be prompted to connect the hardware on the next dialog that is shown below on the
left. Plug in GIGAPORT HD+. Do not click Next yet. Instead, wait a few seconds for the automatic
device driver installation. You can monitor this in the task notification area where Windows Vista /
7 informs that the driver is installed via a bubble message box.
You can now finally click Next on the ESI GIGAPORT HD+ Audio Driver Setup dialog. The
installation is now finished. To confirm this, please check if the ESI icon is displayed in the taskbar
notification area as shown below. Sometimes a reboot is required.
If yes, the driver installation has been completed successfully.
3. Control Panel
This chapter describes the GIGAPORT HD+ Control Panel under Windows. Under Mac OS X no
special Control Panel is required.
To open the control panel double click on the ESI icon in the task notification
area. The following dialog will appear:

ESI GIGAPORT HD+
9
The Output section controls the playback volume of each playback signal from your audio
applications.
There are eight individual faders for each playback channel, divided into the 1/2, 3/4, 5/6 and 7/8
sections. The Mbutton under each channel pair allows you to mute playback for that specific
channel pair. A colored Mbutton indicates that the mute function is enabled. When disabled, the
button is gray.
The Master section allows you to control the playback volume of the main master signal.
SampleRate mode selection
Under Config > SampleRate, you can select the playback mode
and sample rate. By default, playback with up to 8 channels
and 44.1kHz is selected (at up to 16-bit playback resolution).
You can change this to 6 channels at max 24-bit resolution
with either 44.1 or 48 kHz and you can select 96kHz playback
at 24-bit with maximum 2 simultaneous channels.
Please note that you must change these settings before
launching any audio application accessing GIGAPORT HD+.
You cannot change these settings while any software accesses the hardware, so you need to set up
your requirements before you launch your software.
Latency setting
With the Latency menu entry under Config, you can change the latency
of the driver of GIGAPORT HD+. Depending on the typical application
(e.g. for playback of software synthesizers) a smaller latency is an
advantage. At the same time, the best latency setting indirectly depends
on the performance of your system. For most default applications, a
typical latency buffer size between 128 and 256 is standard. On a slow
system, 512 is an option.
Please note that the latency has to be setup before launching any audio application.
