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*
Crossover
A $!/!"dB filter network with selectable Bypass (Full Range), High Pass, Low Pass or
Bandpass modes of operation* Frequency selection is via a $! pin Frequency SIP* The
amplifier is shipped with a &( Hz SIP installed, $' other frequencies are available from
your Xtant Dealer*
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* RM", RM$! and
RM$% also available*
NOTE:
Passive outputs are connected in parallel with front channels*
Service Jumper
Removing the jumper will turn+off amplifier when remote turn+on, ground, and
.$! volt cables are connected to amp* 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*
