Kenwood Excelon XR1001-1

Features

CTA-2006 Compliant: CTA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. CTA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CTA-2006 criteria, the Kenwood Excelon XR1001-1 is rated at 500 Watts RMS x 1 channel with an 85 dBA signal to noise ratio.

Specifications: The manual also lists these non CTA-2006 compliant specifications:

• Power: 1000 watts x 1-channel (into 2Ω at 100 Hz, with no more than 1% THD, 14.4 volts)
• Signal to Noise Ratio: 100 dB (at rated power, 4Ω, 14.4V)

Mono-Power Amp Design: The Kenwood Excelon XR1001-1 is designed with specific features to power your subwoofers with a frequency range between 20 and 200 Hz. This amplifier is not designed to power a full-range speaker.

Wired Remote Control: The XR1001-1 includes a wired remote control with a 20-foot cable that allows you to adjust the volume of the subwoofer from the cabin of the vehicle.

Class D Amplifier Design: The amplifier design is Class D, which uses digital switching power supplies. The result is much higher efficiency (less heat generated) than Class AB.

Low-Pass Filter: The Excelon XR1001-1 has a low-pass filter, continuously variable from 50 to 200 Hz. The slope is selectable at -12dB/octave or -24dB/octave. The crossover is always engaged (it cannot be bypassed).

Infrasonic Filter: The amp has an infrasonic filter with a variable frequency of 15Hz to 40Hz, and a slope of -24dB/octave. The infrasonic filter can be turned on or off, as desired.

Bass Boost: The bass boost circuit is centered at 40 Hz; boost is variable from 0 to +18 dB.

Aluminum Heat Sink: The aluminum heat sink increases the amplifier's heat dissipation efficiency, increasing the life of the amplifier.

Signal-sensing Turn-on: The RCA inputs feature a signal-sensing turn-on feature that powers up the amplifier when an input signal is detected. This allows you to connect a factory stereo without line outputs to the amplifier. You will need to splice male RCA connectors onto the left and right speaker wires coming from the stereo, or use a speaker wire-to-RCA adapter.

Controls:

• Low-Pass Filter Frequency: 50-200 Hz; continuously variable
• Low-Pass Filter Slope: -12dB/octave or -24dB/octave
• Infrasonic Filter: On/Off
• Infrasonic Filter Frequency: 15-40 Hz; continuously variable
• Bass Boost (40Hz): 0-18 dB; continuously variable

Inputs and Outputs:

• Signal Input: one pair of RCA preamp inputs, accepts line-level or speaker-level input signal
• Preamp Output: one pair of pass-through RCA preamp outputs; used to easily connect a second amplifier to the same signal feeding the amp's input
• Power: set screw terminal; accommodates bare wire up to 4-gauge
• Ground: set screw terminal; accommodates bare wire up to 4-gauge
• Remote Turn-on: set screw terminal; accommodates bare wire up to 10-gauge
• Speaker Output: two pairs of set screw terminals; accommodates bare wire up to 10-gauge; the two outputs are internally wired in parallel, making it easy to connect two subwoofers
• Fuses: three 40 amp ATO blade-type fuses
• Remote Control: RJ-14 modular jack for connecting the supplied wired remote control

  Note: The Power, Ground, Remote Turn-on, and Speaker Output terminals are hidden under a removable panel. The supplied 2.5mm and 4mm Allen wrenches are needed to remove the panel and tighten/loosen the set screws.
