INTRO CUSTOMER SER VICE INFO What is QUANTUM? W ARRANTY INFO ® INTRODUCTION QUANTUM.
Intr oduction ® QU ANTUM User Manual ii QUANTUM Congratulations on your purchase of the dbx QUANTUM Digital Mastering Processor! For over 25 years, dbx has been the industry leader in dynamics processing. W ith the introduction of the QUANTUM, we apply our superior dynamics processing technology to the digital mastering process.
® Intr oduction QUANTUM QU ANTUM User Manual Imagine this scenario as an example. A client brings in a stereo mix on a sampling workstation. The mix is r ecorded at 96kHz/24-bit. In or der to cr eate a CD compatible mix you need to con- vert to 44.1kHz/16-bit.

SOFTW ARE OPERA TIONS ® SOFTW ARE Section 3 QUANTUM.
Softwar e Operations ® 20 Section 3 QUANTUM QU ANTUM User Manual This section explains how signals are routed, monitored, and controlled in the QUANTUM. Changes that are made to the QUANTUM’s dynamic processing can be monitored visually and aurally at several differ ent points in the chain.

® Softwar e Operations Section 3 QUANTUM 23 QU ANTUM User Manual The QUANTUM has a unique method of storing your settings. It stores your changes to para- meters as setups.
Softwar e Operations ® 24 Section 3 QUANTUM Saving a setup can be done by following these steps: 1. After you have edited your setups to your liking, press the STORE button. The screen will look like the figure below. Pressing the DA T A WHEEL move the cursor down to either CH 1 Setup, or CH 2 Setup, if you have been editing a dual mono program.
® Softwar e Operations Section 3 QUANTUM 25 2. T o name your setup, there are instructions for you in the Curve Window. Press STORE when you are done. 3. Y ou now must choose what you want to do with the setup you are going to save. Y ou have two choices: you may write over another setup, or you may make a new one.
Softwar e Operations ® 26 Section 3 QUANTUM BYP ASS T o bypass the QUANTUM press the BYP ASS button once. All digital dynamic modules are ren- dered inactive. The QUANTUM also has a CLONE BYP ASS mode, passes the digital audio through the QUAN- TUM to the digital output directly as it came in—a digital clone.
® Softwar e Operations Section 3 QUANTUM 27 Digital Meters The middle portion of the meter rep resents the peak level of the signal. The sides of the meter represent the average peak level. Since the digital output meter is located after dither , changes made to dither will be seen at this meter .
Softwar e Operations ® 28 Section 3 QUANTUM Limiter The limiter’s threshold meter works on the same principle. When the signal is under the thr esh- old setting, the signal is not being processed by the limiter section. The next part of the thr esh- old meter is the “o”.
DET AILED P ARAMETERS ® P ARAMETERS Section 4 QUANTUM.
Detailed P arameters ® 30 Section 4 QUANTUM QU ANTUM User Manual Section 4 Within the multiband compr essor menu on the QUANTUM the following parameters are user adjustable on all setups. Compressor LOC/On/Off Local (per band control) or global on and off.
® Detailed P arameters Section 4 QUANTUM 31 QU ANTUM User Manual Threshold -60 to 0 dB (per band or global) Thr eshold is the signal level at which the QUANTUM starts to compress. If the threshold is set to -10 dBFS, then any signal lar ger than -10 dBFS is compressed, while any signal that has a level lower than -10dBFS is left at the same level.
Detailed P arameters ® 32 Section 4 QUANTUM QU ANTUM User Manual Section 4 The broadband compressor can be used in both stereo or dual mono configurations. W ithin the broadband compressor menu on the QUANTUM the following parameters are user adjustable on all setups.
® Detailed P arameters Section 4 QUANTUM 33 QU ANTUM User Manual Gain -20 to +20 dB This is used to compensate for the gain lost during compression. By using heavy compr ession on a signal and than boosting the signal with the output gain we can than create a signal that sounds much louder than it was.
Detailed P arameters ® 34 Section 4 QUANTUM QU ANTUM User Manual Section 4 Ratio 1:1.0 to 1:15 (per band or global) This is where you decide how much downward expansion you want. This ratio works back - wa rds from that of the compr essor or limiter .
® Detailed P arameters Section 4 QUANTUM 35 QU ANTUM User Manual Hold 0 to 500 m Sec The Hold control sets the amount of time the gate is held open after the signal passes below the threshold point. Release 360 to 5 dB Release sets the speed at which the gate “closes” when the end of the Hold time is r eached.
Detailed P arameters ® 36 Section 4 QUANTUM QU ANTUM User Manual Section 4 Attack .01 to 200 m Sec (per band or global) This is the speed at which the QUANTUM limiter starts to compress the signal once it has crossed the threshold. Set the attack time longer for lower fr equency bands, and shorter for higher frequency bands.
® Detailed P arameters Section 4 QUANTUM 37 QU ANTUM User Manual Hold 0 to 500 m Sec (per band or global) Hold is the time the limiter stays in gain reduction after the signal level has dropped below thr eshold. Hold is useful when you want the limiter to function for a period of time after it has been trigger ed.
Detailed P arameters ® 38 Section 4 QUANTUM QU ANTUM User Manual Section 4 Band 1 FC 20.0 Hz to 20.0 kHz This controls the corner frequency for the low frequency shelving EQ band. Slope 3 to 12 dB / Octa ve Sets the slope of the shelf. Le vel -12 to + 12 dB Amount of boost or cut.
® Detailed P arameters Section 4 QUANTUM 39 QU ANTUM User Manual When in the broadband mode, not only do you have access to the equalizer but also another EQ in the sidechain. Having EQ in the sidechain lets you boost or cut various frequencies prior to the dynamics processor detector .
Detailed P arameters ® 40 Section 4 QUANTUM QU ANTUM User Manual Section 4 Slope 3 to 12 dB / Octa ve Sets the slope of the shelf. Le vel -12 to + 12 dB Amount of boost or cut. Adjustable in 1/2 dB steps. The QUANTUM uses dbx Type IV™ 96 kHz converters.
® Detailed P arameters Section 4 QUANTUM 41 QU ANTUM User Manual Ambience uses a combination of gain and compression to enhance low level information. Reverb tails and acoustic guitar finger picking are examples of sounds that can be enhanced by using the Ambience effect.
Detailed P arameters ® 42 Section 4 QUANTUM QU ANTUM User Manual Section 4 Amount 0 to 100% This controls the amount of De-Essing. The amount control is very much like a combination threshold / ratio contr ol. A higher amount applies more De-Essing to the signal.
® Detailed P arameters Section 4 QUANTUM 43 Shaping S1 or S2 This lets you change between the 2 different digital noise shape algorithms. See Figur e H-2 in the Appendix, pg. 82 Dither Out - All or Digital Sets the routing of the Dither output. When All is selected, the Dither is routed to the digital outputs and the D/A.
