Standard Features
Forced Convection Cooling
All Xtant “X” Series amplifiers employ forced convection cooling for thermal
management
*
An on
+
board thermal sensing circuit regulates fan speed to maintain
optimum operating temperature
*
Fully Regulated PWM Power Supply
All Xtant “X” Series amplifiers feature a Fully Regulated
,
Pulse Width Modulated
power supply
*
This supply technology provides high efficiency and consistent output
performance even when battery voltage is less than optimum

*
Noise Gate
Provides deep muting when no musical signal is present
*
Features include adjustable
threshold and bypass switch
*
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 X
%('
to accept up to
$#
V of input signal
*
Balanced must be used for BTL
inputs using the HLA
*
Modular Expansion Port
All X series amplifiers are supplied with a modular port(s) used for docking any
of Xtant’s signal processing modules
*
Protection Circuitry
Both Thermal
,
Overcurrent and Low Voltage protection are incorporated into the
X
%('*
In the event of a problem
,
the amplifier will reduce its power to maintain
operation
*
In the case of Low Voltage
,
the amplifier will shut off when the battery
voltage falls to
$$
Volts or less
*
Passive Output
The RM
-
Resistor Module is designed to activate the “passive speaker terminals
*
” It
provides
-
dB of attenuation for speakers connected to these terminals

Use to service the amplifier or to make
any adjustments
*
Status LEDs
Four LEDs
,
visible through the cover
,
indicate operational status of all 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
,
and the green LED indicates when the
noise gate is engaged and operational
