Using the Audio Stretch Method of Operation
1. [MAIN MENU > DELAY OPTIONS > START MODE > BUILD DELAY]. Select the delay START
MODE as BUILD DELAY. BUILD DELAY start mode uses an audio stretch algorithm to
gradually increase the delay from zero to the selected duration.
2. [MAIN MENU > DELAY OPTIONS > BUILD/EXIT SPEED]. The BUILD/EXIT SPEED sets the rate
at which the audio is altered by the audio stretch algorithm. There are 16 speeds available
and each setting shows the approximate time required to build 10 seconds of delay.
3. [MAIN MENU > DELAY OPTIONS > SAFE PERIOD]. The SAFE PERIOD is a delay threshold
that you can set to define when it is safe for you to use the DUMP/DROP button. When the
current delay is less than the SAFE PERIOD, the “SECS” label on the main screen flashes. The
Safe Period can be set from 1 to 10 seconds in units of 0.1 seconds.
4. [MAIN MENU > DUMP MODE > DUMP BUFFER]. Select the DUMP MODE which
defines what happens when you press the DUMP/DROP button. The DUMP BUFFER mode
discards the most recently buffered section of audio when the dump button is pressed so
select this.
5. [MAIN MENU > DUMP MODE > BUFFER LENGTH]. Further down the same DUMP MODE
menu, select the BUFFER LENGTH. This option selects the length of audio dumped from the
delay when the DUMP/DROP button is pressed. It can be set from 1 to 10 seconds in units of
0.1 seconds.
6. If you now select CLOSE and exit out of the menu, you can select the delay for the Build
Delay Start Mode. The Delay Time is set from the main screen. Briefly press and then turn
the SELECT DELAY rotary control to select a total delay value. Press again to set the value.
The RB-PD2 is now setup for use.
7. To initiate the delay at the start of a programme, press the BUILD DELAY button.
The delay between audio at the inputs and outputs will increase at the selected build speed
until the selected delay is acquired. Whilst acquiring the delay, the delay time will flash
when it is less than the SAFE PERIOD value. Once the delay has been acquired, it will remain
constant.
8. To discard a section of unwanted audio (of a duration defined by the BUFFER LENGTH)
that has already been internally buffered (e.g. a telephone caller swearing), press the DUMP/
DROP button. The presenter should continue with the programme regardless of the dump
mode currently selected to avoid periods of silence being output.
9. 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.
10. To discard ALL of the buffered audio and mute the audio outputs, press and hold the
DUMP/DROP button to initiate the DROP function. The audio outputs will remain muted
until the button is released. At this point, if the unit was exiting the delay prior to the drop
