function, the delay will remain at zero. Otherwise BUILD DELAY mode will be initiated.
11. At the end of a programme, press the EXIT DELAY button to begin ramping the delay
to zero.
Using the Play File Method of Operation
1. [MAIN MENU > DELAY OPTIONS > START MODE> PLAY FILE]. Select the delay START
MODE as PLAY FILE. This start mode plays an audio file (linear PCM) stored on a Compact
Flash™ memory card inserted in the front panel card slot.
2. [MAIN MENU > DELAY OPTIONS > START MODE > SELECT PLAY FILE]. The SELECT PLAY
FILE option is used to choose the pre-recorded .wav file (stored on the CF card) which will
be played out when the delay is first being built up. Note that the sample rate and
bit depth of the RB-PD2 output must be the same as the recording on the CF card (see page
85: Sample Rate & Sample Width). Also, you can make a recording directly on the RB-PD2
(see page 85: Record).
3. [MAIN MENU > DUMP MODE > PLAY FILE]. Select the DUMP MODE which defines what
happens when you press the DUMP/DROP button. The PLAY FILE mode plays the audio file
selected by the SELECT PLAY FILE option below.
4. [MAIN MENU > DUMP MODE > SELECT PLAY FILE]. The SELECT PLAY FILE option selects
the audio file to be played when the Play File dump mode is selected. Select the required
dump Play File from the list of available files.
5. Select CLOSE and exit out of the menu
The RB-PD2 is now setup for use.
6. To initiate the delay at the start of a programme, press the BUILD DELAY button and begin
your radio programme immediately. When the BUILD DELAY button is pressed, the selected
audio file is played and the unit immediately begins to buffer the audio presented at the
inputs. When the file has finished playing, the output of the RB-PD2 reverts to the buffered
audio and the length of the delay is equal to the duration of the audio file.
7. To discard a section of unwanted audio that has already been internally buffered (e.g. a
telephone caller swearing), press the DUMP/DROP button. When the DUMP/DROP button
is pressed, all the internally buffered audio is discarded, the selected audio file is played and
the unit immediately begins to buffer the audio presented at the inputs. When the file has
finished playing, the output of the RB-PD2 reverts to the buffered audio and the length of
the delay is equal to the duration of the audio file. The presenter should continue with the
programme regardless of the dump mode currently selected to avoid periods of silence
being output.
8. To discard a section of unwanted audio that is about to be presented to the audio inputs
(i.e. the presenter coughing), press and hold the COUGH button for the duration of the
unwanted noise. The current delay will count down whilst the button is held. And once
released, the delay will be built up again using the audio stretch method.
