It is a 800 Watt Class-D Mono Subwoofer Amplifier with on-board electronic crossover and DBO (Dynamic Bass Optimization Circuit). Its compact footprint is only 13 inches x 7-1/16inches x 1-3/4inches, making it perfect for tight installations.
Infinity's new Kappa amplifiers have been engineered to deliver world-class reliable power delivery in an all new compact footprint. So, not only do Infinity's new Kappa amps sound great, but they take less space than any amplifier we have ever engineered and are smaller and easier to install than the amps available from the majority of our competitors.
The Kappa One features a 12dB per octave electronic crossover, permitting you to optimize bass performance based on enclosure type and subwoofer selection.
Instead of providing a conventional fixed-frequency subsonic filter, Kappa One and Kappa Five provide DBO, a variable subsonic filter with variable boost. This exclusive circuit protects woofers in vented boxes, conserving power at the lowest frequencies that vented boxes canâ€™t reproduce and making that power available for bass boost above the high-pass filterâ€™s cut-off frequency. Used with woofers in sealed boxes or in infinite baffle configurations, DBO can deliver flat response through even the lowest octave and protect your woofers from the mechanical dangers of over-excursion while providing tight, accurate bass.
Differential Signal Inputs eliminate ground loops that cause engine noise and work with a variety of output configurations. Speaker-level, line-level single-ended and line-level balanced output signals from any source unit can be connected directly to the Kappa amplifiersâ€™ RCA-type input connectors. High common-mode noise rejection removes alternator noise often present on the carâ€™s chassis and electrical noise radiated into the signal cables. In a nut shell, common mode noise rejection works by amplifying the difference between the positive and negative leads of each signal input. Since noise is present and identical on both positive and negative, itâ€™s cancelled by the circuit and all that is left is the music.
Full-range preamp outputs facilitate use of multiple amplifiers without the need for noisy and expensive adapters or signal splitters.
Smart protection circuitry guards against short circuits in the speaker output leads, under- and over-voltage due to a weak car battery or alternator or a failed voltage regulator in the carâ€™s charging system, and protects your speakers in the event of an amplifier failure. Additionally, Kappa amps consist of thermal protection that never leaves you without your music. Conventional thermal protection circuits shut the amp down completely if it gets too hot. The thermal protection circuit in Kappa amps decreases the output level slightly, reducing the amount of heat generated until the amplifier reaches an optimum temperature. The amp cools itself but the music never stops.
The Kappa One accepts up to 4 AWG power and ground cables using the included 4-gauge terminal adapters.
