The camera's monitoring path converts 12-bit RAW sensor data white balanced 10-bit 1280 x
720 pixel RGB 4:4:4 video. This signal may be modified using ISO, white balance or other RGB
color space adjustments and provides monitor feeds for the RED-EVF, RED-LCD, Preview HD-
SDI and HDMI outputs.
Audio Recording
The RED ONE includes four channels of analog audio input as well as a headphone monitor
and balanced analog audio output. Digitized audio is available on the HDM, Preview HD-SDI
and Program HD-SDI outputs.
Line level analog audio inputs are immediately digitized at 24 bits per sample at 48KHz sample
rate. Microphone level audio inputs are routed via an adjustable gain pre-amplifier before digiti-
zation; gain is generally not applied to Line level inputs, but it may be set to +10dB if desired.
Microphone Input Levels
Recorded levels are affected by the gain setting of the microphone input preamplifier.
At +10 dB, the microphone input level equivalent to Full Scale is +3 dBu (1.1 Volts RMS)
At +54 dB, the microphone input level equivalent to Full Scale is -36 dBu (0.013 Volts RMS).
Line Input Levels
Recorded levels follow the level of the incoming signal.
The input level equivalent to Full Scale is +18 dBu (6.5 Volts RMS).
To achieve 14 dB of input headroom set the nominal input to +4 dBu (1.3 Volts RMS).
Video Monitoring Outputs
In its default configuration, the RED ONE camera can simultaneously support a RED-EVF,
RED-LCD, 3 HD-SDI outputs and one HDMI output, with two of these outputs supporting full
GUI overlay graphics.
Default setting for GUI support is RED-EVF and RED-LCD. However, if either one of these is
not present, full GUI overlay support is automatically enabled on HD-SDI and HDMI outputs.
RED-EVF: 1280 x 848 resolution RGB 4:4:4 progressive video display with Surround View,
frame guides and safe action / title overlays, zebra and false color exposure overlays, wave-
forms, camera status and operation menus.
RED-LCD: 1024 x 600 resolution RGB 4:4:4 progressive video display with Surround View,
frame guides and safe action / title overlays, zebra and false color exposure overlays, wave-
forms, camera status and operation menus.
