English Connection Diagrams

1.Input – Xtant A series amplifiers feature RCA type input connections.

1 Source units with an output signal level of 100mV – 17V may be used.

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

2.Output – These RCA type output connections send full range sig- nals to additional amplifiers eliminating the need for "Y" connectors.

3.Balanced Input – The balanced input switch serves two purpos- es. First, it helps eliminate noises being induced into the signal path

3by isolating the signal 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

Distortion (THD):	≤ .2%
Measured: 20 Hz to 20 kHz at rated power, all channels driven 4Ω
Signal to Noise Ratio:	≥ 100 dB
Measured: A-weighted in 20 kHz noise bandwidth @ 1 volt sensitivity

amplifier to the source unit’s output level.

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

5cy range 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 ampli- fier will play for the best possible performance. The upper end of

the low-pass crossover range can be selected from 40Hz – 120Hz at

624dB per octave with a mono output. The lower 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 individu-

7ally labeled for proper speaker connections. When bridging the amplifier, use the left positive terminal and the right negative terminal only. Warning: do not bridge the amplifier with an impedance lower thean 4 Ohms.

10.Power Terminals – This is the main power connection for the

8	amplifier.	The power and ground wire size should be the
	same gauge.

GND – The ground wire from this connection must be attached to 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

9an inline fuse, then to the positive side of the vehicle battery.

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