Setting DSP Parameters
When you select
DSP
page appears. This page presents a mixing board interface, allowing you to monitor, con-
trol, and perform various DSP operations on digital channels A, B, C, and D.
Note: Digital Signal Processing (DSP) refers to the digital operations that are performed to
modify or control the digital signal.
The signal for a channel (A, B, C, or D) can come from either of two sources:
1
An analog line input signal
2
A digital VoIP audio stream or multicast audio
The level of an analog line input signal can be adjusted via the router's Analog Input Gain
control (see "Router" on page 45), after which the analog signal is converted to a digital
signal. The digital signal can then be routed to one or more of the mixer's four output
channels (A, B, C, and D) via the DSP Router, where it is processed by the mixing board
interface.
