[. . . ] Water and Moisture Install all Xtant amplifiers and accessories in a location free of moisture or exposure to water. 4 The 603x is a "true" three (3) channel amplifier which combines unique performance features with outstanding design flexibility to provide a single chassis "system solution" for most mobile audio applications. With its on-board crossover, a high performance, bi-amplified 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 603x 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: 12 dB (Butterworth)/24dB (Linkwitz-Reily) filter network with selectable Bypass (Full Range), High Pass, or Low Pass modes of operation. 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. 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. All 3/4-channel amplifiers will accept two PQM-1 modules if desired (one PQM-1 per 2 channels of input). BASS BOOST MODULE-LFQ45 The LFQ 45 is designed to add, 4, 8, or 12 dB of Bass Boost to any sound system powered by an Xtant amplifier(s). The LFQ 45 will enhance the bass performance of any subwoofer system, sealed or ported. However, if you are using the LFQ 45 with a ported enclosure, be sure that the 45 Hz center frequency is at or above the vent tuning frequency or damage may occur to the speaker. 8 MAINTENANCE Recommended Cleaning Procedures C l e a n i n g t h e fa n / C i r c u i t B oa r d A. 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 A. For a more thorough cleaning, use window cleaner that is ammonia free.
