Kappa Five - Infinity Kappa 5-Channel 500 Watt Amplifier

Description:

Infinity designed the latest Kappa Series amplifiers to deliver increased efficiency and performance from an extremely compact design. The amp's Class-D design generates less heat, eliminating the need for large heat-sinks. Non-stop Thermal Protection circuitry adjusts the amplifiers output so it runs cool no matter how hard you push your system. Balanced speaker-and preamp-level inputs reject engine whine and other noise from your car's electrical system. A unique detachable power/ground plug lets you connect and disconnect large-gauge power cables in one easy step.

Features:

• Class D/DirectFET Technology: The Infinity Kappa Five 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 Five 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.

• 5-Channel Design: This amplifier is designed to power four full-range speakers and a subwoofer simultaneously. All five channels are 2Ω stable; at 2Ω the power output is 75 watts RMS x 4 to the full range channels plus 300 watts RMS to the subwoofer channel. CEA-2006 compliance is maintained at 2Ω, with less than 1% THD+N. The amplifier's front and rear channels are individually bridgeable, so the Kappa Five can run 5, 4, or 3 channels. When bridged, the front and/or rear channel output is 150 watts RMS into 4Ω.

• 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 low

• 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.

• 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 also acts as a subsonic filter.

• Speaker Level Input: The amp will accept a speaker level signal through the RCA inputs. A speaker wire to RCA adapter is needed (item number 136CLR2SW).

• Crossovers: The Kappa Five has 12 dB per octave crossovers on all the outputs. Each is continuously variable from 32-320 Hz. The crossover on the sub output is low-pass only. The crossovers on the front and rear outputs are independently set to low-pass, high-pass, or full range.
