Section 4 Detailed Parameters

QUANTUM

4.14 De-Esser (cont.)

Amount 0 to 100%

This controls the amount of De-Essing. The amount control is very much like a combination threshold / ratio control. A higher amount applies more De-Essing to the signal.

Type HP or BP

Selects the type of filter used by the De-Esser.

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 -12 dBFS to compensate for any peaks in the program material. If the PRO- GRAM button is pressed during the gain optimize operation, the output gain level will be set to it’s previous level and the QUANTUM will go back to the program mode.

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 -3.0 to 0.0 dBFS

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 24-bit word lengths can be selected.

See Figure H-1 in the Appendix, pg. 81

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.
