12.4 Gain Structure
The 20000DP architecture provides gain adjustments at various points in the signal path and therefore, various
places for muting and level adjustment. Each mute or gain adjustment point serves a different purpose.
Detailed information on signal flow and gain structure is available in the 20000DP Operation Manual. The signal
flow diagrams in chapter 5 (Figure 5-1 and Figure 5-2) are useful signal path references, and the following sections
describe the various adjustment points, all of which are available via the Lake Controller software.
12.4.1 Input Headroom (Analog Inputs Only)
Input Headroom should be set to 12 dBu if the source can be limited to 12 dBu; otherwise it should be set to 26
dBu. This setting does not affect the other gain stages, or the overall noise floor; it allows control of the appropriate
headroom at the input stage only.
12.4.2 Input Mixer
Input Mixer gains can remain at 0.00 dB for most configurations; if only one input channel is used per Module, the
other can be set to -INF.
12.4.3 Module Input Gain
Input Gain is used to adjust the level between different speaker cabinets in the system. This gain can remain at 0.00
dB unless a lower level is required for the cabinet/s driven by this Module.
