Line Level audio inputs are designed to operate at unity gain (0dB Input Level); therefore an appropriate
line output level should be established by your production mixer or other 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. This provides a guaranteed minimum of 18dB of input signal headroom above
reference, in combination with maximum Signal to Noise Ratio for the resulting 24-bit digital recording.
NOTE: If sending the camera a TAPE level line output (-10dBu), adjust the Input Level to +10dB.
MICROPHONE LEVEL AUDIO INPUTS
The 24-bit digital recording level of each Microphone Level input is affected by the sensitivity of the at-
tached microphone and the Input Level setting applied to each of the audio pre-amplifiers.
Pre-amplifier Input Level range is +26dB to +54dB, with a default value of +26dB.
Choose an Input Level that aligns the input signal to the reference line drawn vertically through the cam-
era's PPM, which indicates 0dBu. This setting provides a guaranteed minimum of 18dB of input signal
headroom above reference, in combination with maximum Signal to Noise Ratio for the resulting 24-bit
digital recording.
