Configuration Variables
BD600+ Profanity Delay Chapter 3 Configuration Page 31
Document Version 2.1
POWP
Power-Up mode
This controls whether the BD600+ goes into bypass at power-up (
BYP
), goes directly into processing
(
INLN
), or goes to the state it was in when last powered down (
PREV
). If
INLN
is selected, the unit will go
directly to the in-line mode selected by the
RUN
configuration variable. Note that changes made within
a few seconds of power down will not be remembered.
If
PREV
is selected, the unit will go to the state shown below:

PULS
Heartbeat Indicator
A Broadcast Delay unit like the BD600+ is often left powered up in line for long periods. Since it may
not be used often, and yet is expected to react faultlessly should inappropriate material be detected,
there is value in giving a confidence indication while it is not active. This value, when set, causes the
CONFIG light to discreetly flash according to the selected time, showing that the unit is alive.
REB
Rebuild Time
The rebuild time is the period the BD600+ will need to build from zero delay to maximum delay or to
ramp from maximum delay to zero. This is used to start up the delay or recover from DUMP. The fac-
tory default is 120 seconds, or two minutes, for a typical eight second maximum delay. The actual time
to complete a rebuild may be slightly different, depending on the audio content, and the settings of sev-
eral other configuration parameters. Values above 9999 seconds will be displayed in minutes, for ex-
ample, instead of
12000
(seconds) you will see
200M
.
The displayed time for this variable will change in proportion if
DLAY
is changed, in order to keep the
same quality of signal during rebuild or ramp to zero.
This value should be set following suitable listening tests and will normally be proportional to the
maximum delay value, but should be increased for broadcasts with music content or multiple speakers.
RUN
Run mode
This controls which mode the BD600+ enters when leaving bypass mode. The selections are live , wait
for safe , rebuild , and micro precision delay . Each of these modes is described elsewhere in this chap-
ter. The factory default is live .
SAFE
Safe Time
In many broadcasting situations a control output from the broadcast delay will be used to control a tel-
ephone connection or auxiliary microphone input. The control input is only connected when enough
delay has been built up to allow the operator to delete offending vocals. The delay length which must
exist to allow the audio connection is called the
safe time . The safe time is related to the reaction time
of the operator and the complexity of what would be called offending speech. Normally, the safe time
is several seconds. Since wait for safe is used to quickly build the delay to an amount long enough to
be safe, the safe time is also the time value used by wait for safe . The DUMP button is illuminated only
when the delay is longer than the safe time, unless configured otherwise.
