FREQUENCY MULTIPLIER
The frequency multiplier switch found on channel “A” of the XM6 is used to
multiply the selected high pass crossover points by 20 times.
DEFEATABLE BAND PASS SWITCH
This switch changes the XM6 “B” channel output configuration from a high
pass output to a band pass output.
BASS SHAPER (BOOST AND EQ)
This feature enhances the bass performance of the sound system by providing
up to 18dB of boost from a selectable frequency range of 40Hz to 100Hz.
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 XM6 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.
PHASE CONTROL SWITCH
Depending on their placement, an acoustical delay may exist between the
time the subwoofer, midrange and tweeter signals is heard. With the XM6’s
Phase Inverter, you can compensate for this time delay.
1) Shifting the right output signals on channels “A” and/or “B” 180 degrees
out of phase relative to their left output signals.
2) Shifting the subwoofer output signals 180 degrees out of phase relative to
channels “A” and “B” 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 XM6 series allows you to create an acoustically
flat and smooth frequency response environment.
LINE LEVEL INPUTS
The XM6 crossover features 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 XM6 for 2-, 4- or 6-channel connections.
PARALLEL INPUT SWITCH
This feature allows all XM6 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 “A”, “B”, and sub inputs when the XM6 is used with a source
unit that only has a single or dual pair of RCA or line level outputs.
DUAL STEREO AND SINGLE MONO LINE LEVEL OUTPUTS
The XM6 features three line level outputs each sending independent audio
signals to designated amplifiers. Channel “A” and “B” on the XM6 both
have stereo outputs while the sub channel output is mono.
INDEPENDENT VARIABLE LEVEL CONTROLS
The adjustment of output levels allows precise control of the signals going to
its respective amplifier. Channels “A” and “B” on the XM6 feature independ-
ent left and right output level controls allowing for accurate stereo balance
within the vehicle. Since the sub channel output is mono, a single adjustable
output level control is used to ensure a smooth low frequency response.
CONTINUOUSLY VARIABLE CROSSOVERS POINTS
This feature allows for individual high pass, band pass and low pass
crossover settings that can be selected within a range of frequencies to
ensure optimum system performance. The band pass setting is only operable
when the band pass mode is selected. (See Defeatable Band Pass Switch)
