Section 4 Detailed Parameters
QUANTUM
4.14 De-Esser (cont.)
Amount 0 to 100%
This controls the amount of
Type HP or BP
Selects the type of filter used by the
Width
Sets the Q of the Band Pass Filter.
4.15 Normalization
The Normalizer in the QUANTUM adds gain to the signal right before the output. By adding gain to the signal right at the end of the chain we can then make sure that it goes to tape, disk, etc., as "hot" as possible.
The gain optimize function automatically adjusts the QUANTUM’s gain to maximize output without going over 0dBFS. The gain optimize function sets the output gain of the QUANTUM by "looking" at a sample of music and keeping track of the highest level of that audio signal. The output gain is then set so that the highest level reaches, but does not go over 0 dBFS. The gain optimize can be accessed from the Normalizer, by pressing the EDIT ALL/BAND button. This starts the gain optimize sample period. The EDIT ALL/BAND button must be pressed to complete the gain optimize sample period. EDIT ALL/BAND and PROGRAM are the only but- tons that will allow the user to exit the gain optimize. As the gain is being optimized, the out- put gain is set to
Within the NORM/OUTPUT menu the following parameters are user adjustable:
Normalize On/Off
Turns the Normalizer on or off.
Level –12 dB to +12 dB
The final output stage of the QUANTUM. This lets you adjust the final volume you send out of the unit.
Ceiling
This parameter allows you set the overall output ceiling level of normalization.
4.16 Output
Bits 8 to 24
The selection of the QUANTUM’s final output word length. 8, 16, 20, or
See Figure
Dither SNR2 / HPTPDF / TPDF / OFF
Select from one of 3 dither algorithms. HPTPDF and TPDF are the text book versions, SNR2 is the dbx proprietary dither algorithm.
