Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Class D/DirectFET Technology: The Infinity Kappa One features high-power
Class D circuit topology with DirectFET transistors, a design that increases power output and
overall efficiency, with improved heat transfer from the transistors to the chassis.
CEA-2006 Compliance: The specifications given by Infinity for the Kappa
One comply with the CEA-2006 Amplifier Power Standard from the CEA (Consumer Electronics
Association). All manufacturers who comply with the standard can display the CEA-2006 logo
on their product.
Protection Circuitry: The amp features protection circuits and will shut
itself down in the following cases:
- DC Output: DC voltage is
detected on the amplifier output
- Over/Under Voltage: Voltage
at the +12V (Battery) terminal is too high or too
- Short Circuit: Short circuit
in speaker or speaker wire
Non-Stop Thermal Protection: Kappa amps protect themselves against
excess heat with circuits that cool the amplifier down by gradually reducing output,
instead of shutting down completely.
Status LEDs: Three LEDs on top of the chassis indicate the status
of the amplifier. Two Power LEDs indicate the amplifier is on. The Protection LED indicates
one of the protection circuits has engaged.
Input Level: Rotary control
to match the level of the preamp input signal;
200mV to 6V.
Low Pass Crossover: The Kappa One has a 12 dB per octave low pass
crossover; continually variable from 32-320 Hz.
Dynamic Bass Optimization (DBO): The Dynamic Bass Optimizer (DBO)
is used to enhance low frequency reproduction in your vehicle. Conventional bass-boost
circuits only increase bass at a fixed frequency, and cause the amp to consume considerable
power. The DBO allows you to adjust the frequency, as well as the boost level (up to 12dB),
allowing you to fine-tune the bass in your system to optimize performance. The frequency
control is a subsonic filter.
Power: Set screw
terminal for power wire from battery;
handles up to 4 gauge wire.
Remote: Set screw
terminal for remote turn-on lead; handles
up to 12 gauge wire.
Ground: Set screw
terminal for ground; handles up to 4
Preamp Input: 1 pair of RCA
jacks. The amp will accept a speaker level signal through
the RCA inputs. A speaker wire to RCA adapter is needed (136XDCLR2S,
Preamp Output: 1 pair of RCA
jacks (full range signal for adding amplifiers).
Speaker Output: 4 Set screw
terminals for connecting speaker wires; handles
up to 8 gauge; there are two sets of terminals
to make it easier to connect multiple subwoofers;
they are internally wired in parallel.
Fuses: 3 Slots for 40A ATO fuses
