Our mission is to continually provide you with the best mobile audio ­ anywhere. Our goal is to exceed your expectations. [. . . ] 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. Frequency selection is via a 12 pin Frequency Module (SIP). The amplifier is shipped with a 90 Hz SIP installed, 13 other frequencies are available from your Xtant Dealer. Refer to page 7 of this manual for a list of the available frequencies. Noise Gate: Provides deep muting when no musical signal is present. 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. It provides +4, +8 OR 12dB of Boost at a center frequency of 45Hz. A MAX performance tweak. Remote gain MODULE ­ RGM 1 The RGM 1 adds remote gain control for either subwoofer or stereo channels. Add more bass or add more mids and highs with the RGM 1. Remote mounted control adjusts up to 15dB of gain. With a mounting depth of 1-3/4" and 20 foot RJ11 modular cord included, installation remains flexible. 8 MAINTENANCE Recommended Cleaning Procedures Cleaning the fan / Circuit Board ­ Every 90 Days A. The internal fan in all Xtant amplifiers need periodic cleaning. If you are in a high dust environment, every 30 days is recommended. We recommend that your dealer remove the cover and clean the fan blades with a soft brush. Loose dust can be removed with a vacuum hose. [. . . ] Apply the cleaner/polish to the cloth (not the amplifier) and wipe the surface. Take care not to catch the cloth on the copper mesh.
