Xtant 4.4 Connections & Controls, OFF POSITION 100mV, ON POSITION 200mV, inches of the battery

CONNECTIONS & CONTROLS

1.INPUT – Xtant2.2and Xtant4.4 amplifiers feature RCA type input connec- tions. Source units with an output signal level of 100mV–17V may be used.

1 2 See "Balanced Input" for proper voltage level setting.

2.OUTPUT – These RCA type output connections send full range signals to additional amplifiers eliminating the need for "Y" connectors.

3.BALANCED INPUT – The balanced input switch serves two purposes. First, it helps eliminate noises being induced into the signal path by isolating the

3signal ground. Second, it is used to set the proper input voltage range:

OFF POSITION: 100mV – 8V ON POSITION: 200mV – 17V

4.GAIN – This feature is used to fine-tune the input sensitivity of the amplifier to the source unit’s output level.

5.A.R.C. – The Active Resonance Control (A.R.C.) is a level adjustment that

4reduces the resonant frequencies inside the vehicle to improve the mid-range sound quality. Turn this control either clockwise or counter clockwise until the vocals of the music are up-front and centered in the vehicle. The mid-range sound should be smooth and detailed.

6.XOVER SWITCH – This switch is used to pick the preferred frequency

5range the amplifier will play. A high-pass, low-pass, or full range output may be selected.

7.XOVER FREQUENCY CONTROL – This control allows the user to choose the exact low-pass or high-pass frequency range the amplifier will play for the best possible performance. The upper end of the low-pass crossover range can be selected from 40Hz-120Hz at 24dB per octave with a mono output. The

6lower end of the high-pass crossover range can be selected from 40Hz-120Hz at 12dB per octave with a stereo output.

8.BASS BOOST – This feature will add up to 12dB of low frequency impact to the audio system. The Bass Boost is centered at 45Hz.

9.SPEAKER CONNECTION – These output terminals are individually labeled

7for proper speaker connections. When bridging the amplifier, use the left posi- tive terminal and the right negative terminal only. Warning: do not bridge the amplifier with an impedance lower than 4 Ohms.

10.POWER TERMINALS – This is the main power connection for the ampli- fier. The power and ground wire size should be the same gauge.

GND – The ground wire from this connection must be attached

8to bare metal on the vehicle.

REM – To turn the amplifier on/off, this terminal must be connected to the source unit’s "remote or electric antenna" wire.

+12V – The power wire from this connection must be attached to an inline fuse, then to the positive side of the vehicle battery.

9	WARNING: An outboard fuse must be installed in-line with the power wire within
	18 inches of the battery.
