How do I record and monitor sound?

• RED One I/O
   

  • four 48kHz 24-bit uncompressed audio channels
    
    Each channel input is a female DIN 1.0/2.3 (mini-xlr) jack on the right side of camera.  XLR/mini-XLR pigtails are available with camera.  Mic-level inputs require a special RED pigtail with custom resister network.
    
    There are no external switches or level controls on the RED One.  All audio adjustments are made via menus.
    
    Each channel may be activated individually to reduce the data footprint of the recorded audio/video.  Each input may be switched between mic and line level.  Each mic-level input may be adjusted.  Line-level inputs may NOT be adjusted.  Each channel may provide +48V Phantom Power.
    
    Mic Input Level Range =  +20dB to +54db Default value is +32dB
    
    Use of +48V Phantom Power is not recommended unless using the new
    RED XLR to min-XLR one-piece cable.  (Included)
     

  • 5-pin mini-XLR audio output
    
    2-channel, line level
     

  • 3.5mm headphone jack
    
    Headphone levels and channel mix may be controlled via menus.  There are no external switches or level controls.
    
    The RED One has on-board playback including audio.
     

  • 5-pin LEMO timecode input - jam-sync
    
    This connector supports SMPTE Timecode input and output. Pins 2 and 3 may be used together to receive a balance SMPTE 12M serial time code input, or pin 2 may be used by itself (leave pin 3 open) to receive a single-ended SMPTE 12M serial time code input.
    
    Jam-sync should be activated via a menu option.

  • DIN 1.0/2.3 (mini-BNC) genlock input
    
    Accepts SMPTE 274M-2005 tri-level sync.
     

• How RED One handles timecode
  
  As each recording is made, the RED ONE camera records two independent timecode tracks.
  
  Edge Code is a SMPTE timecode track that always starts at 1.00.00.00 on the first frame of each piece of digital media. It is a sequential code that is continuous from frame to frame and also between clips. Edge Code is also equivalent to RUN RECORD on a video camcorder.
  
  Time Code is a SMPTE timecode track that syncs to the camera’s clock, or if operated in Jam Sync mode, syncs to an externally supplied SMPTE master timecode signal. It is therefore a sequential code that is continuous from frame to frame, but discontinuous between clips.
  
  When in Varispeed or Timelapse recording modes, the timecode counters are updated at the same frame rate as the recording. This means valid SMPTE timecode is created without count jumps that would affect clip playback or editing. If using an external timecode source with Jam Sync enabled, the clip’s master time reference point is the first frame of the recorded clip.
