Lock status indicator
Lock status states: Lock, No lock,
Freewheel, Internal, Bypassed
The Lock status indicator shows the overall ref-
erence clock status. The colors of the “LED” in
this field represent the Icon application warn-
ing/error scheme, which is used for alarms on
e.g. Icon, the Loudness Pilot front UI, GPO and
S N MP.
“Lock (green LED / OK): Loudness Pilot has
obtained lock to the reference signal set in
the Sync Source field.
“No Lock” (red LED / Error): “No Lock” is typi-
cally displayed when there is no signal pres-
ent on the Input that Loudness Pilot is set to
lock to, or if the incoming sample rate is out-
side the legal range (48 kHz +1.7 % / -1.3 %)
and the Clock Fallback parameter is set to
Halt.
“Freewheel” (red LED / Error): “Freewheel” is
displayed when there is no signal present on
the Input that Loudness Pilot is set to lock to,
or if the incoming sample rate is outside the
legal range (48 kHz +1.7 % / -1.3 %) and the
Clock Fallback is set to Freewheel.
“Internal” (yellow LED / Warning): “Internal”
is displayed when Loudness Pilot is set to
sync to its internal referenced master clock
at 48.000 kHz.
“Bypassed” (yellow LED / Warning): “By-
passed” is displayed when the Loudness Pi-
lot hardware bypass relay has been activated.
Sample Rate indicator
The Sample Rate indicator field displays the
sample rate of the sync source Loudness Pilot
is currently following. Sample rate is measured
and displayed with 1 Hz precision (21 PPM @
48kHz).
AES Input State indicators
Indicator states: Green, yellow, grey
The AES Input State indicators show the status
of the AES inputs. States are displayed as fol-
lows:
Green: A green “LED” indicates that a signal
is present and synchronous at the respective
input.
Yellow: A yellow “LED” indicates that a sig-
nal is present and running asynchronously
relative to the sync source. This typically hap-
pens when the upstream device is running at
an internal master clock rate and is not locked
to the house clock.
Grey: A grey “LED” indicates that no signal is
present at the respective input or that the in-
coming sample rate is outside the legal range
(48 kHz ±0.38%).
