Description of the Front Panel
In this section we give you an overview of the front panel's
features. Not all features are labeled, so you may want to reference
the diagram of the DEQ830 on page 18 as you read this section.
Band Select
There are 31 buttons side-by-side on the left half of the
DEQ830's front panel. The first 30 are the [BAND SELECT]
buttons. Above each of the [BAND SELECT] buttons is a
number like "25" or "8k." These stand for the audio frequencies,
measured in Hertz (Hz), which are selected for editing by the
[BAND SELECT] buttons below them. The 31 st button is the
[CHANNEL LEVEL] button, which is explained in the next
paragraph.
Channel Level
The [CHANNEL LEVEL] button is used to set the level of the
currently selected channel or Link Group. This setting is post-EQ
and pre-Master Level.
Real Time Analyzer (RTA)
This button will put the DEQ830 into Real Time Analyzer
