KV2 Audio EX2.5 - Manual (Page 8)

EX2.5 USER GUIDE P. 8
Power On / Thermal LED
This LED turns green when the speaker is turned ON.
The light will continue to be green during normal
operation of the speaker system. The LED will change
from green to yellow under a thermal condition
resulting from overheating of the amplifier system.
Under this condition, the speaker system will shut
down. You can expect for the system to be down for
at least 2-3 minutes depending the ambient tempera-
ture and whether the system is being exposed to
direct sun light.
Signal present
There are individual LED’s for each the Left and Right
signal inputs. The LED turns green when there is
audio signal present in the EX2.5. This signal indicator
can be used to troubleshoot wiring problems.
Limiter LED
This LED turns yellow when the limiter is activated.
Limiter
The EX2.5 employs a protection system based on rms
limiting of the amplifiers. This type of protection
strategy allows the speaker to operate safely under
overload conditions. When the rms “limiter” engages,
the output level of the amplifier is reduced to a safe
operating level.
This type of protection allows the frequency response
of the system to remain unchanged. The control
objective is to regulate the operating temperature of
the transducers magnetics circuits long term. This
ensures no impact on performance due to power
compression and allows the components to retain
their ability to reproduce high dynamics. When
overdriven the rms limiter will disengage only if the
input level is turned down.
Phase Switch
The EX2.5 features a phase switch that changes the
phase of the high pass audio output signal. Changing
the phase of the output signal serves as a tool for
integrating the full range cabinet and the subwoofer
into challenging audio environments. We recommend
using a suitable measuring device for performing
relevant measurements and determining whether the
phase should be reversed.
Level Control
The EX2.5 features a rotary control knob providing
adjustment of the audio level. The operational range of
the control is –6dB to +6dB.
Transporatation
To keep your EX2.5 speakers in optimum condition we
recommend transportation in an optional KV2 Audio
EX2.5 MkII padded cover. There is also a CART-0009
wheelboard for EX2.5. Contact your KV2 Audio dealer
for further details.
Amplifiers and Acoustic Filters
A power amplifier specifically designed and optimized
for the low frequency woofer powers the EX2.5 . The
control system in the EX2.5 processes the audio signal
through a series of electronic filters and circuits
providing equalization, crossover filters, thermal and
overdrive protection.
Output ES2.6
This EP4 connector output allows you to connect the
EX2.5 to one KV2 Audio ES2.6 enclosure thus expand-
ing the capability of the EX2.5. No other cabinet can be
connected to this output and no responsibility will be
taken for any misuse of this facility.
ES2.6 Output connector wiring:
Pin 1 - Power Output (-)
Pin 2 - Power Output (-)
Pin 3 - Power Output (+)
Pin 4 - Power Output (+)

TIP: If the loudspeaker produces noises such
as hiss and popping, disconnect the audio
cable from the loudspeaker, if the noise stops,
then most likely the problem is not with the
loudspeaker. Check the audio cable, source,
and AC power for the source of the problem.
