Fig 8-3: RB-PD2 Rotary Control Operation
Setting the Delay
The target delay of the RB-PD2 is dependent on the selected Start Mode. There are 2 start
modes; Build Delay and Play File.
Build Delay Mode
In Build Delay mode, the delay will be acquired using the automatic audio stretch algorithm
until the target delay has been built up. The rate at which the delay is built up depends on
the current audio stretch algorithm speed setting.
To adjust the delay, lightly press the rotary control to enable the delay edit mode. The
decimal point on the selected delay value on the left hand side of the main screen will
flash to indicate that delay edit mode has been entered. The value of the delay can now be
changed by turning the rotary control. Once the required delay value has been set, press
the rotary control again to return to normal operation. The delay edit mode is automatically
cancelled if no change is made to the delay within a period of 2.5 seconds.
If the current delay is not zero, i.e. a certain amount of delay has already built up, changes
to the delay are implemented dynamically. For example, if the current delay is 7.0 seconds
and a new delay of 5.5 seconds is selected, the delay will automatically decrease to the new
value and the status line will show “DECREASING DELAY”.
Play File Mode
In Play File mode, an audio file stored on a Compact Flash™ memory card is played whilst
simultaneously buffering the audio at the selected audio input source. Once the audio file
has finished playing, the buffered audio is output and the delay is set to the duration of the
file just played.
In this start mode, the selected delay value on the left hand side of the main screen shows
the length of the selected start play file. The selected delay cannot be edited until the start
file has finished playing.
