    After you have chosen a program, you may want to change some of the parameters to meet your specific needs. One of the most useful tools available on the QUANTUM for setting up a proper compression curve is the curve window. In the curve window you can see the com- bined effects of dynamics-related parameters expressed in a graphical format.

    1.3 QUANTUM Wizard The easiest way to program the QUANTUM is using the Wizard. To access the Wizard, press and hold the PROGRAM button. Once in the Wizard mode, you will select the task that you are performing. The QUANTUM will automatically choose the correct chain type for your task.

    QUANTUM The QUANTUM has a unique method of storing your settings. It stores your changes to para- meters as setups. These setups are an immediately accessible library of your changes. No mat- ter what program you are currently working with, you can call up any setup that uses that same configuration: stereo-linked or dual mono.

  • Page 40: Multiband Compression

    The point when the QUANTUM (or any compressor) starts to compress is the "knee." When the QUANTUM starts to reduce the level of a signal abruptly right as it passes over the threshold this is called "hard knee" compression. OverEasy® (soft knee as it is sometimes called) is when the level of the signal is compressed gradually.
  • Page 41 Threshold -60 to 0 dB (per band or global) Threshold is the signal level at which the QUANTUM starts to compress. If the threshold is set to -10 dBFS, then any signal larger than -10 dBFS is compressed, while any signal that has a level lower than -10dBFS is left at the same level.

  • Page 42: Broadband Compression

    The point when the QUANTUM (or any compressor) starts to compress is the "knee." When the QUANTUM starts to reduce the level of a signal abruptly right as it passes over the threshold this is called "hard knee" compression. OverEasy® (soft knee as it is sometimes called) is when the volume of the sound is compressed gradually.

  • Page 43: Multiband Gate

    Release 360 dB / Sec to 5 dB / Sec Release is how fast the QUANTUM comes out of compression. The release is in dB per second. For example, if release is set to 5 dB /sec, signal at 10dB of gain reduction, release time is 2 seconds.

  • Page 44: Broadband Gate

    This sets the maximum amount of attenuation for the gate. 4.4 Broadband Gate The QUANTUM's broadband gate is available in the non-multiband chain types. It works just like the multiband gate with the exception of the fact that it functions on the entire signal band.

  • Page 45: Multiband Limiting

    There are ten levels of OverEasy® that can be used on the QUANTUM's limiters Auto On/Off/LOC and On/Off When auto is turned on the QUANTUM will continuously set the attack / hold / release con- trols itself. It can be set globally or locally per band.

  • Page 46: Broadband Limiting

    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 frequency bands, and shorter for higher frequency bands.
  • Page 47 There are 5 bands of EQ on the QUANTUM that can be used for something as subtle as sweet- ening a mix to drastic changes. Bands 1 and 5 are shelves while 2 through 4 are fully para- metric.

  • Page 48: Xover

    Amount of boost or cut. Adjustable in 1/2 dB steps. 4.8 XOver There are three crossover points on the QUANTUM, creating 4 bands. Tuning them allows you to select which frequencies to process with which of the multiband dynamics processors. The QUANTUM uses phase compensated, Butterworth 1st and 3rd order filters.

    Set this to match the frequency that you would like the QUANTUM to operate it’s internal clock at. If the QUANTUM is slaved to a jittery master clock, the QUANTUM will clean up the jitter and output only clean and steady clock frequencies. If you are unsure of your master clock device, we recommend you use the QUANTUM as the master.

  • Page 57: Digital Input Controls

    This turns the high pass filter (HPF) On/Off. The high pass filter affects only the digital inputs. Use The HPF to remove any DC offset in the input signal. The QUANTUM’s HPF is set at 1.75 Both input levels and the high pass filter are defeated when the clone bypass is activated.

    5.6 MIDI Program Changes Program Changes: When the QUANTUM is set to receive on one or all of the MIDI channels, it will recognize a Program Change command. If the number is legal (i.e., within the device's range of selectable programs) the QUANTUM will respond by changing to the new program.

  • Page 78: Clock Modes

    This is essential for accurate monitoring at different points along the chain. With an analog input and downstream digital units, using the QUANTUM as a master clock will keep the digital signal accurate. While the differences in jittery sync without a master clock may be miniscule, it is better to reduce the vari- ables in favor of accuracy.

  • Page 79: Quantum Sync Input

    Refer all servicing to qualified service personnel. Disconnect mains power before servicing. QUANTUM comes with the sync input terminated. For certain configurations, you may wish to have the sync input be unterminated. However, dbx Professional Products recommends that the sync input be terminated whenever you are using a Superclock, e.g., DigiDesign ProTools®, sync.
  • Page 80 QUANTUM’s sync input. The same is true if you wish to use several QUANTUMs in a tapped configuration. QUANTUM can also be used in a daisy chain fashion. In a daisy chain configuration, each piece of equipment can remain terminated (and should if you are using a SuperClock) and so the termination can remain in the default position.
