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)
