Audio Inputs and Levels
Analog audio comes into the SE-2000 through the XLR connectors on the rear panel (see above diagram). The
SE-2000 supports four XLR Balanced Audio Input channels.
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. 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.
A+V
abruptly at the same time.
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 (if no specific transition is selected, the
sources will dissolve) and watch Audio Input Source channel change from CH2 to CH1, following the video.
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 Video bus at the Fader. 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-session so that you can select an
input and adjust the initial level correctly.
NOTE: Audio cannot be de-embedded by the SE-2000 from a HD-SDI input and Audio will not be
embedded into the SE-2000's HD-SDI PGM outputs. For ideas on how best to do this before and after the
SE-2000 mixer see Example SE-2000 Set Ups (Page 17).
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
activated at a time. When the transition is a CUT, the audio will switch
