Inputs and Outputs
CEA-2006 Compliant: CEA-2006 is
a new system of testing & measurement methods for mobile audio amplifiers. This
voluntary standard advocates a uniform method for determining an amplifier's RMS
power output and signal-to-noise ratio. The criteria for measuring power uses a
DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm
load, with 1% or less Total Harmonic Distortion (THD) plus noise, and at a
frequency range of 20 Hz to 20,000Hz, when applicable. Signal-to-Noise
ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt
into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers
on an equal basis. The Kenwood KAC-X10D under CEA-2006 regulations is rated at
300 Watts RMS x 1 channel with a 80dBA signal to noise ratio.
Mono-Power Amp Design: The
Kenwood KAC-X10D is designed with specific features to power your subwoofers
with a frequency range between 5 to 200 Hz. This amplifier is not designed to
power a full-range speaker.
1-Ohm Stable: The Kenwood
class D mono-amplifier is capable of handling load impedances down to 1-ohm. The
amplifier is rated at 600 Watts RMS x 1 channel in 2 ohms at 100Hz with 0.5% THD.
The amp is rated at over 600 Watts RMS x 1 channel in a 1ohm load.
Class D Amplifier Design: The
KAC-X10D is a Class D mono-block amplifier, which uses digital switching to
amplify audio signals. This design results in high efficiency and less heat.
MOS-FET Switching Power Supply: The amplifier utilizes a MOS-FET
switching power supply providing thermal stability and efficient switching speeds
guaranteeing performance and dependability.
Dressing Cover: The Kenwood KAC-X10D features and attractive
brushed aluminum removable top aluminum cover that eliminates access to power,
ground, turn-on and speaker terminals unless removed. This provides a very clean
look as well as protects the amplifier's connections from being accidentally
touched. The lip of the top aluminum cover also helps protect the amplifier's
controls from being accidentally changed. The cover is held in place by two hex
head screws. An allen-wrench is supplied to remove the cover.
Dual E Sigma Drive: Kenwood's
Dual E Sigma Drive provides a bridged output with an excellent damping factor
that allow the amplifier to pump out an extraordinary amount of high-fidelity
Aluminum Heat Sink: The
KAC-X10D utilizes a cast aluminum heat sink to increase the amplifier's heat
dissipation efficiency, increasing the life of the amplifier.
Parallel Connection: The
amplifier is equipped with two pairs of gold-plated speaker terminals for an
easy parallel subwoofer connection.
Variable Low-Pass Filter: The KAC-X1R has a built-in
filter that is continuously variable from 40Hz to 200Hz. You can turn the
Low-pass filter On or Off.
Infrasonic Filter: This amp
features an -24dB/octave Infrasonic Filter. Ultra-low frequencies that cannot be
reproduced by a subwoofer do not become sound but become unnecessary
oscillations, which affect sound by causing distortion. These frequencies also
waste amplifier power and can cause damage to speakers. Setting the Infrasonic
filter switch to 15Hz or 25Hz cuts the frequencies below the respective
frequency to improve the reproduction performance of the speakers by eliminating
Line Level Inputs: The one set of gold
plated RCA type line-level inputs have a gain (Input
Sensitivity) control. The
Input Sensitivity control will accept an input signal of 200mV to 5.0 Volts.
Line Level Output: The amplifier has a set of
gold-plated line level
outputs for feeding a stereo signal to another amplifier. There is a Line Out
Filter switch on the amplifier that allows you to set the Line Output RCAs of
the amp to have no effects from the amplifiers settings or you can set the Line
Output to carry the same low-pass filter, inputs sensitivity and bass boost
settings to your second amplifier.
Remote Terminal: The KAC-X10D has a
remote terminal jack that is compatible with the Kenwood Bass Boost Wired Remote
Controller (KCA-WR10, sold separately). The optional wired remote allows you to
have independent bass boost control of the amplifier in your system. Using the
optional KCA-WR10 you can set the variable Bass Boost Circuit to 0 to 18 dB and
the variable Bass Boost Frequency to 40 to 100 Hz.
Power Indicator: When the power
is turned on to the amplifier, the Power indicator will light up. This indicator
will turn off with the amplifier and will turn off if the amplifier goes into
Protection circuitry: The amplifier features protection circuits
that will turn the amp off in case of the following events to protect the amplifier
and your speakers:
- Speaker output contacts ground
- Speaker wire short-circuits
- Unit malfunctions and DC is sent to speaker
- Internal temperature is too high
- Voltage is outside of the operating
Front of the Amplifier: The following amplifier's controls
are found on the front of the amplifier:
- Input Sensitivity: 200mV-5V
- Low Pass Frequency: 40-200 Hz
- LPF Switch: On or Off
- Infrasonic Filter Frequency: Off,
15 or 25Hz
- Line Out Filter: On or Off
Front of the Amplifier: All of
the amplifier's connections are found on the front of the amp. The amplifier's
dressing cover must be removed to access the amplifier's
power, ground, turn-on, and speaker terminals.
