2 OPERATION
2.1 Operating Elements
[1] POWER Switches the unit on or off. The unit is ready to operate with the factory
default settings. The subsequent settings remain stored in a Flash EPROM
after switching the unit off (unit contains no battery).
[2] Input dBu FS Rotary switch for coarse input sensitivity setting in 10 dB steps. OFF posi-
tion between microphone and line sensitivity setting ranges.
Mic: Range –40...+20 dBu
Line: Range +14 dBu, +24 dBu
[3] Fine Gain Potentiometer for fine input sensitivity setting.
Range of additional gain: 0...+15 dB.
Headroom: The input sensitivity setting is calibrated in dBu per full-scale. It represents
the dBu value of an analog input signal which causes a full-scale output of
the A/D converter.
Example: A studio works with +4 dBu nominal analog level and uses 12 dB head-
room; the peak level is the16 dBu. The “Input dBu FS” rotary
switch [2] is set to +24 dBu (i.e. gain setting short by 8 dB), and the “Fine
Gain” potentiometer [3] increases the gain by 8 dB.
(Panel) S etting [dBu] = N ominal level [dBu] + H eadroom [dB].
