Xtant 1.1 - Manual (Page 3)

CONNECTIONS & CONTROLS
1. BALANCED INPUT – Xtant1.1i amplifiers feature RCA type input connec-
tions. Source units with an output signal level of 100mV–17V may be used. The
balanced input serves two purposes. First, it helps eliminate noises being
induced into the signal path by isolating the signal ground from amp chasis.
Second, it allows use of any source unit.
2. GAIN – This feature is used to fine-tune the input sensitivity of the
amplifier to the source unit’s output level.
3. SPEAKER CONNECTION – These output terminals are individually labeled
for proper speaker connections.
4. POWER TERMINALS – This is the main power connection for the amplifi-
er. 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.

PERFORMANCE FEATURES
AUDIOPHILE FULL SPECTRUM CLASS D TECHNOLOGY
The Xtant1.1i adds local and global multiple nested feedback loops with premium MOSFETs and
OPAmps for switching stability and audio signal accuracy within the full range spectrum. This
results in an extremely high switching speed—over 1MHz.
Because the switching speed is over 1MHz, we are able to set the output filter frequency high
enough to avoid any phase related distortion within the higher frequency range of the audio sig-
nal. This enhances the musical reproduction by ensuring the higher frequencies (cymbals and
the like) compliment the entire frequency range to bring new realism to the Class D amplifier
sound experience.
The Audiophile Full Spectrum Class D Technology with Xtant’s attention to detail results in a
Class D amplifier that sounds better than many audiophile Class A/B amplifiers. It exhibits an
extremely low noise floor eliminating the “hiss” common to many Class D amplifiers. The
improved dynamic range enables the accurate reproduction of every loud and quiet passage
within the musical range. This makes the amplifier exceptionally suited for musical and theater
applications.
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.
BALANCED INPUT
The Balanced input circuit increases common mode noise rejection and eliminates ground loop
noise while allowing for 100mv to 17 volts of signal input. This circuit also makes interfacing
with any factory head-unit easy.
ADVANCED 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.
SMALL FOOTPRINT
These small footprint mono-block amplifiers are ideal for vehicles that have limited space and
allows for unlimited installation creativity in any application. The mono-block concept also allows
for easy audio and/or video system configuration (2-, 3-, 4-, 5-, 6-, or 7-Channel).
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.
