Standard Features English

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*
