Krix Tektonix and Volcanix innovation
front panel controls
Unlike conventional subwoofers with hard to
reach rear controls, the Tektonix and Volcanix
feature a front panel with precision digital
adjustment. There is no longer any need to pull
your subwoofer out of a cabinet or away from
a wall to set up your system, all functionality
is accessible via the front panel interface. The
front panel display is backlit to aid viewing in
low light conditions. After 45 seconds of button
inactivity the display will return to the volume
menu and the backlight will fade out.

ICEpower® amplification
Your subwoofer is powered by a low distortion
ICEpower® amplifier designed by Bang &
Olufsen ICEpower a/s. This high efficiency
Class-D amplifier generates far less heat than
conventional amplifiers and therefore requires
no bulky external heatsinking. A high-current
switch-mode power-supply ensures full
power can be delivered for sustained periods,
producing maximum dynamics and impact from
your subwoofer.
signal processor
The Tektonix and Volcanix subwoofers feature a
high integrity signal processor through the use
of analogue control stages that form a short
and direct connection from the input terminals
to the ICEpower® amplifier, whilst still allowing
maximum control over the incoming audio
signal.
controls and features
In place of conventional mechanical
potentiometers the signal processor
utilises Microchip® laser trimmed digital
potentiometers, this offers precision adjustment
of volume and filter controls, as well as
eliminating noise, distortion and reliability
issues associated with conventional pots.
This all analogue signal path features only high
quality plastic film coupling capacitors and
JFET operational amplifiers for stable low noise
audio performance.
All aspects of the signal processor, including
fault and monitoring signals, are under
the control of a Microchip® PIC16F690
microcontroller, which is commanded from the
front control panel via a high reliability balanced
RS485 serial data link. The front control
panel has its own PIC16F690 microcontroller
dedicated to managing the LCD display and
user interface.
high performance driver
The Tektonix and Volcanix both feature high
power long throw low frequency drivers. Both
units incorporate a 50mm four layer voice coil
and motor system optimised for low distortion
at extreme sound pressure levels.
symmetrix vent
Enclosures feature Symmetrix bass reflex
venting, with the vent exhibiting the same flare
radius internally and externally. This lowers
subwoofer distortion and serves to reduce vent
turbulence or "chuffing" at high drive levels.
clipping protection
The ICEpower® amplifier features sound
optimised soft clipping protection and will
accurately amplify the input signal to full power
without compression or loss of dynamics. If an
input signal is applied beyond the ICEpower®
amplifiers maximum power limit, soft limiting
will minimise distortion and protect the
loudspeaker driver.
fault protection
Subwoofer amplifiers feature comprehensive
protection systems that will protect the
amplifier and loudspeaker from a range of
possible fault conditions.
The microcontroller constantly monitors the
ICEpower® amplifier module for possible over-
temperature and over-current events, as well
as checking that the AC mains supply is not too
low for proper operation.
If any of these fault conditions occur, the
amplifier will immediately be disabled to
prevent any permanent damage from occurring.
After the fault condition clears, the unit will
resume normal operation. Please see the
troubleshooting guide on page 10 for further
information.
feet
The Tektonix and Volcanix both feature soft
rubber feet to stop unwanted vibration being
transmitted into the floor.
