24.4.2 LINEAR – FULL RANGE
If a better headroom / input dynamic range (than the Linear Mode) is
required, LINEAR-FULL RANGE input mode is provided. No clipping
and no deviation limit is applied to signal processing in this case.
Input headroom ranges up to 20 dB and an overall MPX level control is
not provided. Nominal input level reference is nearer to the left margin
than in the Linear Mode – MANUAL .
Note: Setup should be performed for both the analog and digital audio inputs. The Tiger Shark will store your level
settings for each input separately allowing you to switch between analog and AES/EBU inputs without resetting the input
level. Note that there are different controls for calibrating digital versus analog audio inputs.
1)
The Sensitivity Level (Analog or Digital) parameter sets the gain for both channels. After adjustment, peak indication
hitting the Nominal Input reference point on the display or a little higher (see picture here below) is proper. This
corresponds to around 20 dB system headroom.
2)
If further gain or attenuation is required, the individual left/ right Gains can be adjusted using the Input Left and
Input Right parameters
With Post Gain control set to 0 dB, the reference point displayed in the picture indicates the audio peak level associated
to a 75 kHz deviation.
After digital or analog input calibrating, You may set the analog level of the composite signal on the BNC connector.
Please adjust the Post Gain control until you reach the desired modulation level.
