Reference Level
Reference Level defines the standard operating
level, and scales the Threshold and Target
Level parameters of the Loudness control and
Multiband section. The Threshold of the Limiter
is not influenced by this setting, but is always
relative to 0dBFS.
Typical Reference Level settings would be -20
dBFS in the America and some parts of Asia,
and -18 dBFS in Europe, Japan and some parts
of Asia.
If you wish to relate all levels to 0 dBFS, leave
the Reference Level setting at 0 dBFS.
Analog vs. Digital level
If you use analog interfacing, remember always
to set the relationship between absolute analog
and digital level before adjusting parameters in
the Engines.
Typical analog I/O level scaling would be
+24dBu in the Americas and some parts of
Asia, and +18dBu in Europe, Japan and some
parts of Asia. The figure denotes the analog
level required or produced for a 0dBFS signal.

Note 1: Be careful when changing between
configurations. Moving from Dual Mono to
Stereo will result from parameter settings of the
left (or “A”) channel being copied into the right
(or “B”) channel. Going from Dual Mono to
Stereo and back to Dual Mono will therefore
overwrite original right (or “B”) channel settings.
Note 2: In all configuration modes, linking of
the Brickwall Limiter is set separately on the
Limiter page. Some broadcasters like the sound
of operating left and right limiting without stereo
coupling because they feel that it maximizes
loudness and widens the stereo image.
On dual mono sources, of course you should
always choose un-linked Limiter operation.
