CEA 2006 Compliant: The X1200M's power ratings are
measured according to the strict standards dictated by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even if they come from
different brands. Manufacturers who adhere to the standards can display the CEA
2006 logo on their products and packaging. The amplifier features the following
power specifications.
- 4-Ohm RMS Power Rating: 800 watts x 1-channel in 4-ohm at
20-200Hz with 1% THD
- 2-Ohm RMS Power Rating: 1200 watts x 1-channel in 2-ohm at 100Hz
with 1% THD
- Max Power Output: 2400 watts x 1-channel Peak
Mono-Power Amp Design: The Kenwood X1200M is designed with
specific features to power your subwoofers with a frequency range between 20-200
Hz. This amplifier is not designed to power a full-range speaker.
Class D Amplifier:
For subwoofer applications, Class D amps are very efficient and their
small size offers installation flexibility. Before amplifying an incoming
signal, a Class D amp converts the signal to digital. Digital signals can be
amplified very efficiently, so you get a lot more power with less current. Less
input current reduces power supply size and generates less waste heat, thus
reducing the heat sink size. The amp then converts the amplified signal back to
analog.
Dual Sigma Drive: This advanced negative feed back circuit improves
damping factor and increases accuracy and sound quality. When a signal is passed
to a subwoofer, like a 50Hz note, the speaker will move and create the note.
However, because the speaker has mass and a suspension, it will not stop moving
once it is in motion. This extra
movement (sound) creates a type of distortion that is not part of the original
signal. The negative feedback circuit senses this unwanted movement and send out
an opposite pulse to stop the speaker like an electronic brake.
Dual Power Supply:
This design provides one power supply for positive current and one power supply
fro negative current. The result is cleaner voltage source, less failure due to
short circuit or power loss due to variances in transformer tolerances, and less
transformer noise even when the positive and negative loads are unstable.
Dressing Cover: All of the amplifier's control are located under a
removable extruded aluminum dressing cover. The dressing cover also hides the
amplifier's connections for a neat installation. The dressing cover can be
removed using the included small hex-wrench to unscrew two M4 x 8mm hex-head
screws that hold the dressing cover in place.
Cooling Fan: There
is a cooling fan, one top vent, and two vents located on each side of the
amplifier to help dissipate heat and ensure cool, reliable operation. Make sure
not to block these vents or fans when you install the amplifier.
Protection circuitry:
The amplifier features protection circuits that will turn the amp off in case of
the following events:
- Speaker output contacts ground
-
Speaker wire short-circuits
-
Unit malfunctions and DC is sent to
speaker output
- Internal temperature is too high
-
Loss of ground of head unit or amp
Controls
Gain Control: The X1200M features
a gain control with the following adjustable input sensitivity - 0.2V to 5.0V.
Variable Low Pass Filter: The built-in variable LPF (50-200Hz) allows
you to select a variable frequency and
remove damaging high frequencies from the subwoofer pathway for more bass output
with less distortion.
Infrasonic Filter:
The infrasonic filter eliminates inaudible ultra low frequencies that can cause
unwanted distortion. The filter can be adjusted between 15Hz to 40Hz depending
on the subwoofer and enclosure being used.
Bass Boss Wired Remote Ready:
The optional KCA-WR10 wired remote (113KCAWR10, sold separately) allows bass boost frequency adjustments
(15-40Hz) and
level adjustments (0-18dB) for bass. If you are using two amps, you can
use a phone splitter so one bass boost can operate both amps.
Line Out Filter: The Line Out Filter switch changes the audio signal
output to the Line Out terminal on the amplifier. You can choose for the X1200M
to filter the audio output to the other amplifier connected via the amp's line
output, or allow the X1200M to pass a non-filtered audio signal onto the
additional amplifier.
Connections
Power And Ground Terminals: The amplifier features hex-head set-screw
Power and Ground terminals that will accommodate 6 to 4 AWG wire.
Turn-On Terminal: The amplifier features a hex-head set-screw Turn-On
lead terminal that will accommodate 12 to 8 AWG wire.
Speaker Terminals: The amplifier is equipped with two pairs
of gold-plated speaker terminals for an easy parallel subwoofer connection.
RCA Inputs: The amplifier features one pair of gold-plated RCA input
connections.
RCA Outputs: The amplifier has a set of line level outputs
for feeding a stereo audio signal to another amplifier.
Fuse: The amplifier contains three 30-amp fuses.
