Xtant2.2/Xtant4.4 Amplifier Owner’s Manual
PERFORMANCE FEATURES
ACTIVE RESONANCE CONTROL
Active Resonance Control (ARC). This circuitry compensates for the unwanted resonance
frequencies created when installing midbass or midrange speakers in the kick panels or lower
door areas of a vehicle.
FULLY REGULATED PWM POWER SUPPLY
Xtant amplifiers feature a Fully Regulated, Pulse Width Modulated power supply. This power
supply technology provides high efficiency and consistent output performance even when
battery voltage is less than optimum.
CROSSOVER
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.
BALANCED/FLOATING INPUT
When enabled, this circuitry helps to eliminate “system noise” associated with ground loops.
When combined with the input sensitivity adjustment, it allows the amplifier to accept up to 17V
of input signal.
PROTECTION CIRCUITRY
Both Thermal and Overcurrent protection are incorporated into Xtant amplifiers. In the event of
a problem, the amplifier will reduce its power to maintain operation.
STATUS LEDS (LOCATED ON THE TOP OF THE AMPLIFIER)
Three LEDs indicate operational status of Xtant amplifiers. The red LED illuminates when the
amplifier is “ON”, the yellow LED indicates that overcurrent protection is engaged, the orange
LED indicates that the thermal protection circuit is engaged.
OPTIONAL PERFORMANCE ENHANCEMENTS
HIGH LEVEL ADAPTER (HLA)
High Level Adapters allow you to connect a source unit with speaker level outputs to your Xtant
amplifier.
