MatchBox USB
User Manual
1 – Overview
Multi-media PCs are becoming more important as media sources, not only in residential settings, but in a variety of
commercial audio installation settings as well. The MatchBox USB is a cost-effective general purpose solution for direct
digital transmission and reception of media PC audio streams over a CobraNet-based system.
The MatchBox USB features USB Plug-n-Play installation at full speed communication (12.1 Megabits/sec), compatibility with
most standard PC audio applications, and is fully compliant with USB Audio 1.1 standards.
The standard MatchBox (900-00110-01) operates as four separate stereo audio devices. Each device can potentially be
either an input device, which passes audio from CobraNet to the PC or an output device, which passes audio from the PC to
CobraNet.
Not all standard MatchBox device combinations are available. See section 1.2.
The MatchBox 1x8 (900-00122-01) operates as a single device with eight audio channels. Each set of two channels can
potentially be either an input pair, which pass audio from CobraNet to the PC or an output pair, which pass audio from the
PC to CobraNet.
Device configuration for the standard MatchBox and channel configuration of the MatchBox 1x8 is achieved over the USB
connection using a tool embedded in Attero Tech Control Center application.
The CobraNet configuration of the MatchBox is also achieved using the Attero Tech Control Center software. This control
software allows real-time manipulation of all signal routing and signal processing. This is done using SNMP via the Ethernet
interface.

1.2 – How to Use a MatchBox USB
The MatchBox USB can be used in a variety of applications. The MatchBox allows any software that has stereo audio
playback or recording capability to have access to CobraNet audio. This manual will show the steps needed to install the
MatchBox USB into an existing CobraNet system. The steps are:
1. Connect the device.
2. Install the MatchBox in Windows.
3. Install the MatchBox USB Device Configuration software.
4. Configure the devices.
5. Set up CobraNet audio parameters.
The MatchBox is available in two forms.
The standard MatchBox operates as four separate audio devices, each with two audio channels. Each device may be set up
as inputs or outputs as follows:
o
4 stereo audio output devices
o
3 stereo audio output devices and 1 stereo audio input device
o
2 stereo audio output devices and 2 stereo audio input devices
Both channels in each device are always the same direction as the device itself. A device cannot be set up with one
channel as an input and one as an output.
The MatchBox 1x8 operates as a single audio device with eight channels. Like the standard MatchBox, the audio direction
of the audio channels can be set up as inputs or outputs. The options are as follows:
o
8 output channels
o
6 output channels and 2 input channels
o
4 output channels and 4 input channels
o
2 output channels and 6 input channels
A second MatchBox can be added on the same PC to increase the number of audio channels available if required and both
types may be used at the same time.
