What is the purpose of the
neutrik adapter I posted? According to the
manual the only audio input is the AEU
BNC. They're just trying to
send the mixed audio at all times to the
switcher which is doing the encoding of the video feed. Which
page did you see the Beringer recommendation?
All they need is either
RCA /
XLR / 1/4 Stereo put into the
unit.
The ATEM products do not
switch audio, they rely on external audio switching/mixing. The ATEM Production Switchers support analog audio inputs and outputs via a breakout cable, however the Television Studio has no analog audio inputs or outputs, only a single
AES input on a
BNC connector. All of the ATEM units then incorporate the single two
channel audio input into the output signal as the audio portion of the
HDMI signal, embedded two
channel audio on the
SDI signal and embedded in the H.264 signal for the USB output.
The Behringer format converter recommendation is on Pages 17 and 100 in
http://www.blackmagic-design.com/media/3218836/Switchers%20Manual.pdf.
Another factor to keep in mind is that the ATEM inputs accept 525/29.97 (
NTSC), 625/50 (
PAL) SD, 720p/50, 720p59.97, 1080i/50 or 1080i/59.97
SDI and
HDMI inputs and the
HDMI inputs will also accept
[email protected], 720x576@50Hz, 1280x720@50 or 59.94Hz and 1920x1080@50 or 59.94Hz computer inputs. You select the video standard to be used, however you select one video standard that is applied to all inputs and outputs. To get the price
point they have the ATEM switchers do not include internal scaling or transcoding, thus all inputs must be the same format and that will also be the output format. So you can have both
SDI and/or
HDMI inputs but no mixed HD and SD or SD and widescreen graphics or anything like that, all input signals must be the same format and standard. A lot of people who are thinking of using it with mixed formats miss that detail and then have to do all sorts of external transcoding and conversion.
