Detailed Parameters

DriveRack®

The DriveRack 4800 and 4820 provide a wealth of processing capabilities. This processing can be broken into two distinct sections: Input Processing and Output Processing. Both the Input and Output sections offer two types of processing functions, Fixed and Insert. Fixed processing modules can be linked and/or switched with a similar type of function, but they are fixed in their location in the DSP path. An example of a Fixed processing function is the Input Graphic EQ or EQ1. The Input Graphic EQ can be linked between adjacent channels. Insert processing functions have fixed locations in the DSP chain, but they dif- fer from Fixed processing functions because there are several different types of processing that can be put into these locations. An example of Insert Processing is the second Output Insert. This Insert gives you a selection of Compressor, Limiter, Noise Gate, or Automatic Gain Control. Like the Fixed functions, they too can be linked between adjacent channels if there is the same type of function in the other channels.

The following section outlines each of the Fixed processing functions available in both the Input and Output sections (Sections 6.1-6.10). Following the Input and Output Fixed functions, the Insert Processing functions is also outlined (Sections 6.11-6.19). These outlines provide GUI images for each of these functions and describe the various parameters associated with each function.

6.1 - Input Mixer

Each input DSP channel can be configured with either an Input Mixer or Router. The Input Mixer lets you mix between the input signals. Master Gain is also available, along with Pink Noise On/Off and Pink Noise Gain.

Analog,AES/EBU, and CobraNet faders

Provides gain control for each of the input sources (–inf to +20dB).

Pink Noise Gain fader

Provides Gain control of the internal Pink Noise source (-20 to +20 dB).

Pink Noise On/Off switch

Turns the pink noise on or off.

Master Gain fader

Provides Gain control for the Mixer module (–inf to +20dB).
