HIGH PASS AND LOW PASS VARIABLE LEVEL CONTROLS
The adjustable high pass and subwoofer output levels allow precise control
of the signals going to the respective amplifier.
CONTINUOUSLY VARIABLE CROSSOVERS POINTS
This feature allows for individual high pass and low pass crossover settings
that can be selected within a range of frequencies to ensure optimum system
performance.
BASS BOOST EQ
This feature found on the XM4 enhances the bass performance of the sound
system. The output level is continuously variable with a maximum boost of
18dB @ 45Hz.
BASS-DRIVE™ (REMOTE SUB GAIN CONTROL PORT)
The optimum subwoofer output level changes with road noise that varies
according to vehicle speed, wind speed and road surfaces. With our exclusive
Bass-Drive™, the subwoofer output level can be adjusted via the model R S
remote control to minimize the undesirable effect of fluctuating road noise.
PULSE-WIDTH MODULATED (PWM) SWITCHING POWER SUPPLY
The Coustic XM4 features a Pulse-width modulated (PWM) switching power
supply. The PWM is used to ensure consistent output performance and to
eliminate unwanted noise caused by voltage fluctuation.
SUB PHASE CONTROL SWITCH
Depending on their placement, an acoustical delay may exist between the
time the midrange/tweeter signals are heard and the time subwoofer signals
are heard. With the XM4’s Phase Inverter, you can compensate for the time
delay by shifting the subwoofer output signals 180 degrees out of phase
relative to the front and rear output signals.

FEATURES
ASYMMETRICAL ELECTRONIC CROSSOVER DESIGN
The advantage of asymmetrical crossovers over “symmetrical” crossovers is
the ability of the former to eliminate undesirable peaks and dips in frequency
response caused by resonant frequencies present in all enclosed space. Since
the crossover points can overlap or underlap the resonant frequencies (i.e.
"asymmetrically"), Coustic XM series allows you to create an acoustically flat
and smooth frequency response environment.
LINE LEVEL INPUTS
XM series crossovers feature pre-amp inputs for use with source units that have
RCA or line level outputs. An independent set of line level inputs are provided
on the XM4 for front, rear and sub connections. These connections allow for
front to rear fading and independent sub control (see Parallel Input Switch).
SPEAKER LEVEL INPUTS
The Coustic XM2 features speaker level inputs, allowing the crossover to
work with source units that do not have RCA or line level outputs. The audio
signal can be obtained by simply connecting the XM2’s speaker level input to
the source unit’s speaker level outputs.
PARALLEL INPUT SWITCH
This feature allows all XM4 outputs to be driven with either a 2-, 4- or
6-channel input configuration. An adapter is not needed to split the source
signal to the front, rear, and sub inputs when the XM4 is used with a source
unit that only has a single or dual pair of RCA or line level outputs.
STEREO AND MONO LINE LEVEL OUTPUTS
The XM2 and XM4 feature line level outputs allowing for independent stereo
high pass and mono low pass signals to be sent to designated amplifiers.
The XM4 includes dual high pass outputs for front and rear fading capability
while allowing for a constant mono subwoofer output.
