4.8 General Firmware Features

Note: The following features are accessed via IQwic 
software unless otherwise stated. Refer to Figure 
4.24, DBC Network Bridge Signal Flow Block Dia-
gram for feature locations in the audio signal chain.

4.8.1 Input Level Meters

Audio level peak program meters are provided for 
each input. The meters sense the audio signal 
immediately after analog to digital conversion, and 
respond with 1.7 millisecond attack and 350 milli-
second release. Meter range is from –60 to +20 dBu 
with 0.5 dB resolution. Calibration is in dBu when 
the input is in “line” mode and set at 0 dB.

4.8.2 Input Dynamic Cut/Boost Meters

Meters are provided for each Input A/B Processing 
Section to indicate the overall cut or boost being 
applied from all signal processing features that 
affect input gain, including Auto-Leveler, Input 
Compressor, and Auto-Mixing. Meter range is from 
–60 to +20 dBu with 0.5 dB resolution.

4.8.3 Output Level Meters

Audio level meters are provided for each output. The 
meters sense the audio signal immediately after the 
audio output processing block, and respond with 
1.7-millisecond attack and 350-millisecond release. 
Meter range is from –60 to +20 dBu with 0.5 dB 
resolution.

4.8.4 Output Dynamic Cut/Boost 
Meters

Meters are provided for each output to indicate the 
overall cut or boost being applied from all signal 
processing features that affect output gain, includ-
ing Ambient-Leveler and Output Limiter. Meter 
range is from –60 to +20 dBu with 0.5 dB resolu-
tion.

4.8.5 Memory Backup

The DBC Network Bridge settings are stored in 
high-endurance flash memory whenever a parame-
ter is changed. Changed settings are updated every 
few seconds.

4.8.6 Presets

The parameters for all functions in the DBC Network 
Bridge can be saved as presets and each can be 
given a unique 32-character name. A total of 32 
user presets can be stored in the DBC Network 
Bridge’s flash memory. Presets can be recalled via 
the front-panel selector buttons, IQ for Windows 
preset selector controls, from within events, or by 
an external system controller via the Multi-Function 
Control Port.

• 

Preset Segue:

 When a preset is selected, the 

Preset Segue feature provides a smooth transition to 
the new preset. Preset Segue can be set to either a 
fixed time in seconds or a fixed rate in dB per sec-
ond. Range for fixed time in seconds is 1 to 255 
seconds. Range for fixed rate in dB per second is 
from 0.5 dB to 40 dB.

4.8.7 Real Time Clock

The onboard Real Time Clock tracks day, date, hour, 
minute and second, and may be set to any date and 
time desired, or to match that of the computer run-
ning IQ for Windows software. The clock is used as 
a time reference for the Events Scheduling feature. 
Internal capacitor storage allows the clock to run for 
up to 45 days without power being applied to the 
DBC Network Bridge.

4.8.8 Events

User presets can be scheduled for recall as an Event 
at a specific date and time, and also can be set to 
repeat. A total of 32 Events can be scheduled, and 
each Event can be given a unique 32-character 
name.
