The audio circuit on the VBrick 9000 encoder uses mixed signal technology (a combination
of analog and digital signals). The encoder has two audio input connectors for each channel
(left and right). The input signals are unbalanced and have a usable voltage range up to 10
dbU.
Various channel configurations and bit rates can be set on the

page. The encoder provides controls for mic level vs. line level balanced mode support, input
gain/attenuation, automatic level controls, and other advanced audio features. The encoder
supports three types of electret microphones:
• Electret Condenser, battery operated or plug-in power (SoundBlaster style)
• Dynamic type balanced or unbalanced
• Externally-powered phantom types and otherwise amplified types such as wireless.
The microphone preamplifier provides a selectable 16 or 32 db of gain (boost). Various
configuration parameters control how the input signals are conditioned as well as how the
resulting audio is compressed. The audio input signal parameters define how audio is
connected, what the signal ranges are, the style of electrical interfaces, and the number of
Note: If you are working with an encoder with presentation features enabled, your
interface or functionality may differ slightly for this section in that video input and
video encode settings are two separate menu options under

. See
the Presenter Encoder Video Input topic if you need more information on the
differences.
