INTEGRATED STATUS DISPLAY
In simple terms, ISD is the brain of your amplifier and a smart one at that. In
tech terms, it’s a complex microprocessor circuit that constantly monitors the
signal, power output and protection conditions of the amplifier. Each amplifier
has a built in backlit display that shows the end user what is happening inside
the amplifier.
ICE SYSTEM COOLING
Xi amplifiers feature a sleek and clean cosmetic design, but underneath is the innovative ICE cooling system. ICE addresses the three key ways to keep amplifiers cool:
Thermal Mass, Surface Area and Airflow.
SIGNAL
Lights blue when the amplifier provides signal to your speakers.
CLIP
Lights red when amplifier reaches near maximum output and begins to
clip the audio signal. This is very powerful tool as it allows you to set up
the system for maximum output without the need of an expensive and
complicated O-scope. In normal operation the clip indicator should be
flashing often during dynamic parts of the music, this is normal. What is
not normal is if clip indicator is staying lit for long portions (more than 4 or
5 seconds) of time, then you need to reduce system volume or gain of the
amplifier.
PROTECT
Lights red if there is a problem with the audio system. For example, speaker
wire gets pinched/shorted together, blown a voice coil or running too low of
an impedance, the ISD display will let you know.
THERMAL MASS
Xi amplifiers are built like a brick house the heatsink is no different. It’s loaded with
10 grams per millimeter of Aluminum. Most other amplifiers use 6 to 7 grams per
millimeter. This means the amplifier has more thermal mass to soak up the energy/
heat created by your music than a standard amplifier. Pickup a Xi amplifier and you
will know it’s a serious amp.
SURFACE AREA
Eventually we need to get the energy/heat out of that heatsink and into the air.
What you can’t see is the internal extrusion of the heatsink is loaded with fins
that increase the surface area. These heatsink fins are also engineered to work in
conjunction with the diecast endcaps.
AIRFLOW
Exile engineers have integrating venting into the endcaps of the amplifier. This
allows the amplifier to exhaust the hot air out. Most amplifiers are completely sealed
and this can build up unsafe heat levels inside the amplifier that overtime can cause
failures.
