MONITOR AUDIO

OVERVIEW

The DSMC can record up to two (2) discrete stereo channels of uncompressed 24-bit, 48 KHz audio. A Pro
I/O Module provides two (2) channels of microphone level or line level audio inputs, and up to four (4) digital
AES audio inputs. In total, the DSMC supports eight (8) incoming audio channels, and can record up to four (4)
audio channels.
Input signals are routed via a high-quality pre-amplifier and soft clip analog limiter (the limiter is optional) to
achieve the desired recording levels and maximize dynamic range.
Audio data is synchronized with video and timecode and embedded in the R3D file. You can export audio data
from REDCINE-X PRO as separate audio files.
Audio is also embedded in any HD-SDI and HDMI output connected to the DSMC BRAIN.
For more information about using the Pro I/O Module, see the
com/downloads.
