CONFIGURATION
__________________________________
This section is a guide to configuring system settings and ensuring they are set correctly. This can vary
depending on the studio setup. The configuration settings covered in this section are; Operating Level,
Sync Reference, DIG I/O, Timecode, Machine Control, Networking, Preferences, and Software.
OPERATING LEVEL
______________________________________
The input and output levels of RADAR
can be matched with the input and output levels of other pieces of
equipment in the studio. Although the inputs and outputs can be adjusted independently, all inputs share
the same operating level. The same holds true for all of the outputs.
Because a zero meter reading on a digital recorder represents the absolute maximum level (dBFS –
decibel Full Scale) that can be recorded, a much lower nominal level should be specified.
With analogue VU meters, 0 VU (+4dBu) represents this nominal level and above that is headroom, which
allows for dynamic surges and peak transients.
Setting RADAR’s analogue audio input and output levels can be done by setting the level in dBu at which
RADAR
will reach full scale (0 dBFS), or by setting the level in dBFS that a 0 VU (+4dBu) signal will meter
on RADAR’s meterbridge. The ANALOG I/O LEVEL dialogue in the I/O MENU will have a prompt of
either 0 DBFS or +4 DBU as the reference.
Choosing a reference of 0 DBFS will display a prompt for setting the full scale input and output levels (0
dBFS), as a dBu value between +18 and +24 dBu.
Choosing a reference of +4 DBU will display a prompt for setting where a signal at +4dBu will register on
RADAR’s meters in dBFS. This will be a value between -14 and -20 dBFS. This value is commonly
referred to as headroom.
