This primary alarm has an
integrated
peak response to program sig-
nal overloads, allowing the occasional transient to slip through.
However, a secondary indicator, marked
OVERLOAD
(arrow) has in-
stantaneous peak response. This secondary flasher is held for a suf-
ficient period to make even the briefest overload visible to the opera-
tor.
NOTE:
This alarm, marked by the arrow in the illustration, is
shared with the peak limiter as well (see Page 18), and it is
not
asso-
ciated with a rear-panel closure for remote indication.
Output Gain
Setting
With the
w
cursor positioned with the
p
and
q
buttons,
OUTPUT gain:
is also variable over a ±15dB range, adjusting both the
analog and digital outputs concurrently.
There is no provision for
independent gain control over the analog and digital outputs,
al-
though a common setting should be satisfactory for both modes,
which are available simultaneously.
Analog
Output Level
With reference to the maximum, fully-limited ceiling output of the
peak limiter, an
OUTPUT gain:
setting of
0
d
B
will yield a balanced
analog line output of 0dBu. Thus to match a n4dBm pro-
gram line,
OUTPUT gain:
would be set to
+4
d
B
. To match typical con-
sumer equipment line levels,
OUTPUT gain:
would be set somewhere
in the
-10
d
B
range.
Digital
Output Level
Again, referred to the fully-limited ceiling output of the peak lim-
iter, an
OUTPUT gain:
setting of
0
d
B
sets the digital ceiling value at
20dBFS. This can then be adjusted over a ±15dB range.
PROCESSING FUNCTIONS DISCUSSED AND ILLUSTRATED
Status Screen
In the
SETUP AND STATUS
display area, the Status screen is home
base for the various menu options. It shows whether audio is pre-
sent (
GATE OPEN
), and which of the three processing functions is en-
abled:
Y
for yes,
N
for no, and the numerical indication of
50u
or
75u
when the independent pre-emphasis-protection limiter is enabled
(see Page 20).
