Images can be stored on a high-speed Compact Flash, RED-DRIVE™ or RED-RAM™ media.
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 processing, Peak Level meter,
headphone monitor and 2-channel balanced analog audio output. Audio is digitized at 24-bit
depth and 48KHz and recorded in synchronization with video and timecode to the attached
media. Digital audio is also embedded in the HDMI, Preview and Program HD-SDI outputs.
Line Level and Microphone Level analog audio input signals are routed via a high quality A/D and
pre-amplifier, whose gain stage may be controlled using the Input Level control to achieve the
desired audio reference / recording level.
Line Level Inputs
Line level audio inputs are designed to operate at unity gain (0dB Input Level), therefore an ap-
propriate line output level should be established by your field production mixer or other external
signal source.
Reference signal level for Line inputs is 0dBu / 0.775 volts RMS / -20dBFS when operating at
0dB Input Level. The maximum input signal that can be applied before the onset of input signal
clipping is +18dBu / 6.5 volts RMS / - 2dBFS. i.e. this setting supports a guaranteed minimum of
18dB of input signal headroom above reference, plus the maximum available Signal to Noise Ra-
tio for the resulting 24-bit digital recording.
Microphone Level Inputs
The recorded signal levels of Microphone inputs are affected by the sensitivity of the microphone
and the Input Level setting. Range is +10dB to +54dB, with a default value of +32dB. The cam-
era operator should choose an Input Level that aligns the input signal to the reference line drawn
vertically through the camera’s PPM, indicating 0dBu.
This setting supports a guaranteed minimum of 18dB of input signal headroom above reference,
plus the maximum available Signal to Noise Ratio for the resulting 24-bit digital recording.
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
