LINE LEVEL INPUTS

0dB: Line Level audio inputs are designed to operate at unity gain (0dB), therefore use 0dB and set a
0dbu (- 20dBFS) line level output from the production mixer or other external signal source.

era's PPM, indicating 0dBu. This setting provides 18dB headroom above reference level before signal
clipping and the digital audio recording will be at maximum Signal to Noise ratio. Range is +26dB to
+54dB, with a default value of +26dB.
