5.3.2 Input Delay

Starting from the 

Input Path

 window, you can access the 

Input Delay

 win-

dow (Figure 5.19) by clicking on its icon (shown above).

A delay can be added to any of the Input Processing Sections in order to time-
equalize the various input signals. Delay is displayed in IQwic software in 
time, feet, and meters. Control range is from 0 to 100 milliseconds in 20 
microsecond steps. Delay time can be adjusted up to a maximum of 2 seconds 
for each channel.

Hardware Delays

The delays in the DBC Network Bridge are fixed and allow very precise align-
ment of audio signals. Delay elements are available in each Input Processing 
Section to ensure that audio alignment is attained. The processing time delays 
of each of the various components in the DBC Bridge and CobraNet network 
need to be taken into account in this alignment process. These are fixed laten-
cies in order to keep filter alignment together.

The various delays in the DBC Network Bridge are:
• Input A/D Converter: 667us
• DAC Converter: 520us
• Input Processing: 1.665ms
• Output Processing: 1.665ms
• CobraNet: 5.333ms
