With its on-board crossover, a high performance biamplified system is easily configured. By utilizing the on-board crossover's four (4) RCA line outputs, you can steer specific frequency ranges to additional amplifiers, thus eliminating the need for external, active crossover components. As with all Xtant "X" Series amplifiers, the A48 incorporates an on-board noise gate, forced convection thermal management system, and a Pulse Width Modulated power supply for high efficiency and unsurpassed reliability. All these features are encased in Xtant's exclusive finish of stainless steel and copper! 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. 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: Selectable 12/24 dB per octave "Butterworth" filter network with selectable Bypass (Full Range), High Pass, Low Pass and Bandpass modes of operation. The amplifier is shipped with a 90 Hz SIP installed, 13 other frequencies are available from your Xtant Dealer. By utilizing one of three (3) frequency modules included, any frequency from 20 Hz to 20kHz can be chosen. The "Q" ranges from 1 to 10 in value, allowing a wide variety of bandwidth adjustment to address the subtle tuning requirements common to mobile audio systems. LOW FREQUENCY EQUALIZER ­ LFQ45 The LFQ45 will add Bass impact to any system. A MAX performance tweak. Remote gain MODULE ­ RGM 1 The RGM 1 adds remote gain control for either subwoofer or stereo channels.

We recommend that your dealer remove the cover and clean the fan blades with a soft brush. Have your dealer check the fan for obstructions if your amplifier over heats. When the Thermal Protection Circuit is engaged, the orange LED will be illuminated and power may be reduced. If present, use a low pressure air source to blow-off the dust particles. DO NOT use a high-pressure source, brush or any similar device to clean the circuit board! Caution: B. Cleaning the Amplifier ­ Every 30 days A. For a more thorough cleaning, use window cleaner that is ammonia free. Apply the cleaner to the cloth (not the amplifier) and wipe the surface.
