CONNECTIONS & CONTROLS
1. INPUT
– Xtant3.1 and Xtant6.1 amplifiers feature RCA type input connec-
tions. Source units with an output signal level of 100mV–17V may be used.
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 sig-
nal 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. XOVER FREQUENCY CONTROL
– This control allows the user to choose
the exact low-pass frequency range the amplifier will play for the best possible
performance. The upper end of the crossover frequencies can be selected from
40Hz–120Hz at 24dB per octave.
6. BASS BOOST
– This feature will add up to 12dB of low frequency impact
to the audio system. The Bass Boost is centered at 45Hz.
7. SUBSONIC
– This feature limits the lower end of the low-pass frequencies
sent to the subwoofers. The subsonic feature includes a selectable on/off
switch, and a control knob used to adjust the lower end of the low-pass range.
The subsonic setting can be selected from 20Hz-80Hz at 24dB per octave.
8. RLC
– This port allows the use of the optional Xtant “remote level control”
(RLC). The RLC is a bass control module that can be installed in any location
within the vehicle for remote adjustments.
9. SPEAKER CONNECTION
– Two sets of speaker terminals are provided for
dual woofer applications. When connecting a single woofer, use only one set of
speaker terminals.
WARNING:
Xtant3.1 and Xtant6.1 amplifiers are not bridgeable.
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
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 an 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.

Xtant3.1/Xtant6.1 Amplifier Owner’s Manual
PERFORMANCE FEATURES
SUBSONIC FILTER
The subsonic filter maximizes your Xtant amplifier’s output when a specifically tuned subwoofer
system is used.
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 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.
REMOTE LEVEL CONTROL (RLC)
The RLC or Remote Level Control allows a bass control to be adjusted remotely from the driver’s
seat.
