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)

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.
