BD600+Profanity Delay
Document Version 2.1
The BD600+ may be used as a broadcast profanity delay - this is its primary function and factory de-
fault mode. When power is first applied to the BD600+, the unit's audio inputs and outputs are by-
passed through a relay. Pressing the BYPASS button places the unit in-line with 0.00 seconds delay. If
the audio levels are adjusted properly, there should be no perceptible difference when the unit is
switched in. Note that since the BD600+ by default uses true relay bypass, there might be a slight
click. The 4-digit display will now read 0.00 which indicates no delay. The red indicators on several of
the buttons will be lit, showing which buttons are valid choices. The lighting of the indicators changes
depending on the BD600+’s state (or mode). Since the unit is at 0.00 seconds delay and in-line, it will
be in
live
mode. The following is a list of the few different modes in which the unit may be placed:
Note that the BD600+ may be configured to power up or exit bypass in different modes. See
Chapter 3 Configuratio
n for more de-
tails.
Modes
bypass and configuration
- delay is set to 0.00 seconds, the audio is bypassed directly from input
connectors to output connectors.
live
- bypass relays are open (unit is in-line), delay is set to 0.00 seconds.
static
- bypass relays are open (unit is in-line), delay is not changing.
rebuild
- bypass relays are open (unit is in-line), delay is slowly increasing.
ramp to zero
- bypass relays are open (unit is in-line), delay is slowly decreasing. Unit goes to
live
when it reaches 0.00 delay.
wait for safe
- bypass relays are open (unit is in-line), delay is filling with audio, but outputs are
seeing input audio without delay. Unit switches to
rebuild
mode when safe delay time is reached.
If wait for safe is cancelled, the unit will return to
live
mode.
wait and exit
- bypass relays are open (unit is in-line), input audio is not going into delay, but out-
put audio is coming from the delay. The delay length is reducing rapidly. The unit will go into
live
mode when it reaches 0.00 delay. The SNEEZE button is disabled. If wait and exit is cancelled, the
unit will return to the delay value it had when wait and exit was started.
sneeze
- bypass relays are open (unit is in-line), input audio is not going into delay, but output au-
dio is coming from the delay. The delay length is reducing rapidly. When the SNEEZE button is
released the unit will go back to the previous mode.
panic
-
bypass relays are open (unit is in-line), input audio is going into the delay but is not heard
until the
panic
operation is complete. A jingle is played from the Compact Flash card or the outputs
are muted to allow an external audio source to be used. The unit will enter
rebuild
mode once the
jingle is complete or the configured mute period is over.
insert
or
station break
-
bypass relays are open (unit is in-line), input audio is going into the delay
but is not heard until some time after the
insert
operation is complete. A jingle is played from the
Compact Flash card or the outputs are muted to allow an external audio source to be used. The de-
lay length is increased by the length of the inserted audio.
Functions and Features
By default on power-up the BD600+ is in
bypass
mode. Press the BYPASS button to put the BD600+
in
static
mode. The delay is now at 0.00 seconds. After delay build is initiated and until the delay is re-
duced to 0.00 seconds, all audio should pass through the BD600+ before going to the transmitter to
avoid audible discontinuities.
