it has a power output that allows you to connect another KGEAR speaker or passive
subwoofer from the KGEAR series and drive them with its onboard amplifier, with a
set to 3 different thresholds depending on your needs.
ON, the input signal threshold is -52dBu,
which means the amplifier switches on
immediately when the signal is higher than
this minimum threshold. This mode is useful
for those who need quick and reliable audio
feedback, especially when the speaker is
used to reproduce speech audio signals
and important announcements.
-42dBu. This means the amplifier switches
on only after a stronger signal has passed
the chosen threshold. This feature is
particularly useful for avoiding low-level,
noisy signals from entering the circuit and
compromising the signal-to-noise ratio.
A middle threshold can also be selected:
to keep the speaker switched on.
