Audio Inputs And Levels; Audio Outputs - Datavideo HS-2000 Instruction Manual

Audio Inputs and Levels

Analogue audio comes into the HS-2000 through the XLR connectors on the rear panel (as above diagram).
The HS-2000 supports four XLR Balanced Audio Input channels.
NOTE: Audio cannot be de-embedded by the HS-2000 from a HD-SDI input and Audio will not be
embedded into the HS-2000's HD-SDI PGM outputs.
There are two kinds of switches next to each XLR input under AUDIO IN: The LINE/MIC switch is used to
set the audio as LINE in or MIC in. When LINE in is selected please also set the 48V ON/OFF switch to OFF
in order to prevent burn-out damage to the audio circuit/Mic*.
The 48V ON/OFF switch is for Phantom power. If you want to use MIC in, please set the LINE/MIC switch
first, and then if using a Condenser microphone* turn ON the 48V ON/OFF switch. Or if you wish to use a
Dynamic microphone please turn OFF the 48V ON/OFF switch.
*NOTE: Always double check the manual for the microphone being used to see what advice it gives
regarding power as some MICs have internal batteries too.

Audio Outputs

There are two XLR audio output channels A and B. These can act as a stereo pair or as a dual mono output
depending on the stereo mono switch setting. See page 14 also.
A+V Button
Try this: With the A+V button engaged or lit, select Channel 2 on the Main Source bus (of course, you must
have a valid video and audio source connected). Notice that CH2 is lit in the Audio Source section. Now,
select channel 1 on the Sub Source bus. Work the T-Bar to manually perform a transition from CH2 to CH1
and listen for the Audio Input Source channel changing from CH2 to CH1 also.
When the A+V button is not engaged or off, you can manually select which of the 4 Audio input channels will
be applied to the audio out connections. In fact, you have to select one or more of these channels, or there
will be no audio present at the audio out connections.
The A+V button should be inactive while doing level settings at the beginning of a session so that you can
select an input and adjust the initial audio level correctly.
The Audio Input Channel Selectors and Level pots are the first
stage in the audio signal path. Each channel carries the audio
associated with a video input channel. When the A+V button is
active, the audio follows the video through a transition. This
means that when this LED is lit, only one channel of the Audio
input section (CH1, CH2, CH3, CH4) can be active at a time.
When the transition is a CUT, the audio will switch over abruptly
at the same time.
