MINIMUM SYSTEM REQUIREMENTS
PC - Windows Vista / 7 / 8 / 8.1 or 1 0 (32 or 64 bit)
with 1 available USB 2.0 port.
MAC - Mac OSX 1 0.7 or Higher with I available USB
2.0 port
DRIVER AND SOFTWARE INSTALLATION
(WINDOWS)
This text explains how to install the SubZero SZ-
A12 under Windows 10. If you use Windows Vista,
Windows 7, Windows 8 or Windows 8.1, the steps
are basically the same. Make sure to install the
driver before connecting the interface. You can find
the drivers on the Gear4music website.
6
INSTALLATION
Simply connect to your SubZero SZ-AI2 2x2 USB
Audio Interface via an available USB 2.0 port.
There is no need for external power as this
unit draws its power from the USB port. After
the connection of the interface, the operating
system automatically detects it as a new hardware
device. Modern operating systems like Windows
Vista/7/8/10 or Mac OS X usually detect the
hardware directly and installs the correct USB
audio drivers automatically.
You can use the SZ-AI2 now in typical consumer
audio applications that do not need special
professional ASIO driver support. For example, this
could include Windows programs used for DVD
playback or more simple DJ applications that don’t
require ASIO.
The SubZero SZ-AI2 2 Channel Audio Interface
is a high-resolution device capable of advanced
processing of audio content. It is built to have
low-CPU resource needs, but the unit will perform
better on a system with higher specification. For
more information on this, see minimum system
requirements below.
Connect the SubZero SZC-300 Condenser
Microphone to the SubZero SZ-AI2 2x2 USB Audio
Interface via the included XLR cable to the Mic 1
or Mic 2 input. Please ensure the +48V is enabled
as the SZC-300 condenser microphone requires
phantom power to function correctly.
We recommend switching between low impedance
for microphones or high impedance for guitar/
instruments thanks to the INS 1 or INS 2 knobs.

To start the installation, launch the setup program,
which is an .exe file that is inside a recent driver
download from the Gear4music website. The link is
below:
https://www.gear4music.com/driver-downloads
Alternatively, you can find the driver in the
Windows folder of the included Installation DVD,
by double clicking on it. Typically the filename
is something like SZ A12 USB vX.YY_setup.exe
where X.YY is the version number of the driver.
When launching the installer, Windows might
display a security message. Make sure to allow the
installation. For information about the EV certificate,
contact Gear4music Customer Service on the
contact details at the end of the manual. After that,
the following dialog on the left will appear.
Click Next.
Now click Install. Files are now being copied.
You will be prompted with a Windows Security
message. Confirm it by clicking Install. After a while
the installation then will be completed, and the
following dialog will appear:
Once you see the window on the above, click
Finish. We strongly suggest to select Yes, restart
the computer now and then click Finish. You can
connect the interface to your computer anytime
if not done yet. Windows will automatically setup
the system so you can use the device. Once the
system starts again and you are logged in with the
hardware connected, you will see that the interface
control panel is now automatically being loaded
by looking at the SZ icon in the taskbar notification
area. If you can see it, the driver installation has
been completed successfully.
WINDOWS AUDIO SETTINGS
In the Windows Control Panel (under Hardware
and Sound > Sound), you can select the default
playback device that is used by all audio
applications that don’t have their own preferences,
you can select the SZ-AI2 and make it your
default audio playback device. However, most
DAW recording software will allow you to set up
an additional output, allowing you to just use
the interface for sending sound to active studio
monitors whilst recording, for example.

8
CONTROL PANEL UNDER WINDOWS
This is the SubZero control panel, where you can
edit parameters of the interface. The controls are
simple and intuitive to use, and are as follows.
The control panel gives an indication when the
audio interface is active and ready to use. You can
see this when the mute buttons turn from grey
colour to dark red colour, and when the level
adjustable audio level indicators appear. If these
two parts are not showing, there is a connection
issue, meaning the audio interface is not active.
When active, you can edit the input and output
levels of the audio from this screen, with an
interactive level indicator showing you the level
in real time. You can also mute inputs and outputs
using the MUTE button at the bottom of the panel.
Pre-sets can be saved and loaded. Simply click File
> Pre-set > Save/Load to carry out these tasks. This
allows you to save your level settings so that they
are the same each time you use the audio interface.
Sample rates, latency and buffer number can all be
edited in the config menu.
CONTROL PANEL UNDER MAC
Mac OS X already provides support for class
compliant USB audio devices such as the SZ-AI2.
This means that no software or driver needs to
be installed to use this interface under Mac OS
X. Simply connect the unit with the supplied USB
cable to your Mac and you can start using it. To
make the usage simpler, a control panel application
is included that can be installed from the included
DVD (Mac OS X folder) or downloaded from the
Gear4music website. To install it, open the .dmg file
and then you can drag the control panel icon into
your application folder.
Controlling some of the basic interface options
under Mac OS X can also be done via the Audio
MIDI Setup utility from Mac OS X.
