HDMI TC In
Use a DSLR camera that outputs timecode over its HDMI output connection.
A few examples of cameras that do this are the Sony a7s and Panasonic GH4.
Connect their HDMI output to the HDMI TC In port on the MixPre-3’s right hand
panel and set Menu>Timecode>TC Mode to HDMI TC In. Refer to the camera’s
user guide to determine how to output HDMI timecode from the camera since
all cameras do it in a slightly dierent way.
When the MixPre-3 receives HDMI timecode, it is displayed on the Home
screen beneath the current lename. Each time you press record, the incoming
timecode value is stored inside the MixPre-3’s WAV le. Most popular video
editing applications will be able to read this timecode value and sync the audio
with the camera video.
Aux In 1, Aux In 2
LTC, otherwise known as SMPTE Linear Timecode is the most common timecode
standard. Many professional cameras and other devices output this format.
This can be received by the MixPre-3 via its Aux/Mic In 3.5mm connector.
To enable Aux In Timecode:
1. Set the Aux In Mode to Timecode (Menu>Inputs>Aux In Mode) - this is only
available in Advanced mode.
2. Set Menu> Timecode>TC Mode> to Aux In 1 or Aux In 2.
When the MixPre-3 receives Aux In timecode, it is displayed on the home
screen beneath the current lename.
Time of Day (TOD)
Use TOD mode, when you want the recorded WAV les to be timecode stamped
with the time of day. The time of day is derived from the MixPre-3’s built-in
date/time clock. This mode is not used for frame accurate synchronization
with external devices. Rather, it is used as simple way of logging what time a
recording took place.
Timecode Frame Rate Auto-Detection
With both the HDMI TC In and Aux In Timecode modes, the MixPre-3 auto-
detects the incoming timecode frame rate and stamps the recorded les
accordingly.
