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 dierent 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.
