The camera's four audio channels may be monitored in pairs: either 1L - 2R or 3L - 4 R or a quad mix of
1+3L – 2+4R based on the MIX parameter, and the Volume adjusted as follows.
Volume: (master volume) Adjusts headphone volume equally for Left and Right outputs.
Range is -18dB to 0dB in 1dB steps. Default is -9dB.
Volume Left: Trims volume for Left output. E.g. Volume –6dB + Volume Left +1dB = -5dB
Range is -12dB to + 6dB in 1dB steps. Default is 0dB.
Volume Right: Trims volume for Right output. E.g. Volume –6dB + Volume Right -1dB = -7dB
Range is -12dB to + 6dB in 1dB steps. Default is 0dB.
NOTE: The above notes apply to cameras configured with Rev B audio hardware. Cameras shipped
prior to Sept 15 2008 (and not yet upgraded to Rev B) were supplied with Rev A audio hardware,

USB-2 MASTER

This port permits the camera to operate as the Slave camera in a Master / Slave camera pair. To establish
control, plug the square end of a USB-2 cable into the lower USB port of the RED ONE™ camera to act
as a Slave, and the rectangular end of a USB-2 cable into the upper USB port of the RED ONE™ camera
to act as the Master. Then power cycle both cameras. On boot up the two cameras will automatically es-
tablish Master / Slave mode.
Once connected using the USB cable, User Interface commands and remote triggers received by the
Master camera are transmitted to the Slave camera.
