External Trigger Mode; Trigger Modes - Sony PCM-3348HR Operation Manual

5-6 External Trigger Mode

Function
In the external trigger mode, an external trigger signal
activates the writing to or playback from the sound
memory.

5-6-1 Trigger Modes

There are two trigger modes.
• Retriggerable mode
If the trigger signal is applied during sound memory
playback, playback restarts from the beginning of the
sound memory.
During writing to sound memory, applying the trigger
signal has no effect.
• Non-retriggerable mode
During sound memory playback, even if the trigger
signal is applied again, playback continues until the
end of the sound memory.
During writing to sound memory, applying the trigger
signal has no effect.
External trigger signal input connector
The trigger signal can be connected either to the PCM-
3348HR or to the RM-3348HR. For triggering writing
to the sound memory, an input signal to either
connector has the same effect. For triggering playback
from the sound memory, however, the functions are
different, as follows.
• SOUND MEMORY EXT TRIGGER IN connector
on the RM-3348HR rear panel
This always operates in retriggerable mode.
• TRG INPUT connector on the MEM board in the
PCM-3348HR or SOUND MEMORY TRIGGER
INPUT connector on the rear panel of the PCM-
3348HR
A switch setting on the MEM board determines
whether the unit operates in retriggerable or non-
retriggerable mode.
