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 le (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 le (stored on the CF card) which will

be played out when the delay is rst 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

83: Sample Rate & Sample Width). Also, you can make a recording directly on the RB-PD2

(see page 83: Record).

3. [MAIN MENU > DUMP MODE > PLAY FILE]. Select the DUMP MODE which denes what

happens when you press the DUMP/DROP button. The PLAY FILE mode plays the audio le

selected by the SELECT PLAY FILE option below.

4. [MAIN MENU > DUMP MODE > SELECT PLAY FILE]. The SELECT PLAY FILE option selects

the audio le to be played when the Play File dump mode is selected. Select the required

dump Play File from the list of available les.

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 le is played and the unit immediately begins to buer the audio presented at the

inputs. When the le has nished playing, the output of the RB-PD2 reverts to the buered

audio and the length of the delay is equal to the duration of the audio le.

7. To discard a section of unwanted audio that has already been internally buered (e.g. a

telephone caller swearing), press the DUMP/DROP button. When the DUMP/DROP button

is pressed, all the internally buered audio is discarded, the selected audio le is played and

the unit immediately begins to buer the audio presented at the inputs. When the le has

nished playing, the output of the RB-PD2 reverts to the buered audio and the length of

the delay is equal to the duration of the audio le. 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.
