KV2 Audio EX6 - Manual (Page 9)

NOTE: Ensure that all cabling carrying
signal to multiple amplifiers
and active speaker systems is wired
correctly. Make sure that the polarity has not
been reversed. Reversed polarity can cause
severe degradation in frequency response and
can also impact the dispersion characteristics
of the speaker.
Power On / Signal LED
This LED turns green when the speaker is
turned ON. The light will turn yellow when
signal is present.
Low Cut Switch
The EX6 features a 90 Hz High Pass Filter.
Pressing the button engages this filter
allowing the speaker to reproduce frequencies
only above 90Hz
Limiter
The EX6 employs a protection system based
on rms limiting of the amplifiers. This type of
protection strategy allows the speaker to oper-
ate safely under overload conditions. When
the rms “limiter” engages, the output level of
both amplifiers is reduced to a safe operating
level. This type of protection allows the
frequency response of the system to remain
unchanged as the level is lowered. By not
compressing or limiting peak signal, dynamics
also remain unchanged. The control objective
is to regulate the operating temperature of
the transducers magnetic circuits long term.
This ensures no impact on performance due
to power compression and allows the compo-
nents to retain their ability to reproduce high
dynamics. When overdriven the rms limiter will
disengage only if the input level is turned down.
Thermal protection
In the unlikely event of over heating the speaker
system will shut down. You can expect for
the system to be down for at least 2-3 minutes
depending on the ambient temperature and
whether the system is being exposed to direct
sun light.
NOTE: The EX6 features a finless
heatsink that allows it to operate in
any position. There is also an internal
fan located inside the amplifier module.
The fan speed is dependent on two factors;
the temperature of the heat sink and the
output level of the speaker.
As temperature increases, so does fan speed.
As audio level increases, fan speed also
increases as a preventative measure designed
to keep the heat sink temperature low. Under
normal operating conditions, the fan noise
remains inaudible. Please contact KV2 Audio
or a local service representative should the
system enter a thermal condition under normal
operating conditions.
Transportation
To keep your EX6 speakers in optimum
condition we recommend transportation in
an optional KV2 Audio EX6 padded nylon
cover (EX6CVR) or a professional road case.
