Quickstart Guide
This quick start guide briey explains the steps required to get the RB-PD2 up and running if
you just want to get the unit on-air quickly.
There are 2 dierent methods of operation for using the RB-PD2. The rst is to use the Audio
Stretch algorithms to build up a delay time which can then be ‘dumped’ in audio segment
lengths that you dene. The second is to Play a File from a Compact Flash card which can be
inserted into the slot in the front panel.
For both methods, there are 2 menu options that need to be set prior to operating the
delay: Start Mode and Dump Mode. Start Mode denes how the RB-PD2 initially builds up
the delay period and the Dump Mode denes what happens when the DUMP/DROP button
is pressed. Other options such as audio source and sample rate are not discussed here as
they do not aect the operation of the unit.
To change options in the main menu, use the SELECT MENU rotary control to the right of
the front panel; press and hold it for 1.5 seconds to enter the menu, turn the control to
highlight the required menu item and press to select it.
The last item shown in each menu is >CLOSE. Selecting close exits the system menu and
returns to the main display. In each sub-menu, the penultimate item shown is <BACK.
Selecting <BACK displays the previous menu.
