SYNCHRONISERS, DELAYS & SILENCE DETECTORS - RB-PD2

SAFE PERIOD

This option selects the safe period duration, i.e., amount of delay that needs to be built up

before the DUMP button can be used without muting the outputs. To edit the safe period,

turn the rotary control until the highlight is over the safe period value. Press the rotary

control to enter edit mode. The highlight changes to a ashing line under the current value.

Now turn the rotary control to select a new safe period between 1 and 10 seconds in units

of 0.1 seconds. When the required value is shown, press the rotary control again to leave

edit mode. Now turn the rotary control to select either OK which saves the new value, or

CANCEL which discards the changes.

The “SECS” label on the right hand side of the main screen, next to the current delay value,

ashes when the current delay is less than the safe period. If the safe period is set to the

same duration as the dump length, it provides a quick visual indication of when the dump

can be used without the outputs muting, as would be the case if the dump period is longer

than the current delay.

The default safe period is 2.0 seconds.

DUMP MODE

This option selects the mode of operation when the DUMP button is pressed. From the

main system menu select DUMP MODE. The available options are DUMP BUFFER, PLAY FILE,

BUFFER LENGTH and SELECT PLAY FILE.

l Dump Buer – This option discards a pre-selected amount of audio from the internal

delay buer. For example, if the current delay is 10 seconds and the dump buer

length is 4 seconds, when the dump is activated, the position at which the audio at

the selected input is stored in the internal memory buer is moved back by 4 seconds.

This eectively overwrites the last four seconds of audio and the delay will be reduced

to 6 seconds. The audio stretch algorithm will automatically activate after the dump to

return the delay to the selected duration.

l Play File – This option plays a pre-selected audio le on a Compact Flash™ memory

card and discards all of the currently buered audio. Delay acquisition begins again

immediately and the new delay length is equal to the duration of the le played.

l Buer Length – This option selects the dump buer length when the Dump Mode

is set to Dump Buer. To edit the buer length, turn the rotary control until the

highlight is over the dump buer value. Press the rotary control to enter edit mode.

The highlight changes to a ashing line under the current value. Now turn the rotary

control to select a new dump buer length between 1 and 10 seconds in units of 0.1

seconds. When the required value is shown, press the rotary control again to leave

edit mode. Now turn the rotary control to select either OK which saves the new

value, or CANCEL which discards the changes.

l Select Play File – This option selects the audio le to be played when the Play File

dump mode is selected. It shows all available audio les on the Compact Flash™

memory card which match the current audio conguration settings (sample rate

and sample width). If the card has sub-directories dened, these are also shown.
