ON/OFF SWITCH
The SI 30 modulator and the NT 20 plug-in mains unit have no
ON/OFF switch. The green LED at the front of the SI 30 indicates
that the modulator is ready for operation.
In standby mode, the SI 30’s current consumption is very low.
However, unplug the mains unit when you are not going to use the
SI 30 for some time.
AUTOMATIC ON/OFF FUNCTION
The SI 30 features a convenient automatic on/off function. When an
audio signal reaches the modulator, it is switched on (L 1 lights up). If
there is no audio signal for about 3 to 4 minutes, the modulator
automatically switches off.
The automatic on/off function depends on a certain threshold voltage.
If the signal voltage falls below this threshold, the modulator auto-
matically switches off after 3 minutes (L 1 goes off). In this case,
increase the volume on your sound source (please see paragraph
“Adjustments on your sound source”).
