[. . . ] The 302a can drive a complex speaker system or, be used to create a high-powered, bi-amplified, three-channel system when paired with Xtant's 301a mono amplifier. The on-board "Balanced Line Inputs" will accept a wide range of input signals ­ from your OEM Factory head-unit to the latest advances in CD headunit technology. The "Balanced Line" circuitry also helps eliminate noise (alternator whine) induced into the signal cables. As with all Xtant amplifiers, the 302a incorporates a forced convection thermal management system, a Pulse Width Modulated power supply for unsurpassed reliability and three on-board accessory ports allow performance upgrades via Xtant's plug-in modules. All these features are encased in Xtant's exclusive finish of polished stainless steel and copper! Standard Features Forced Convection Cooling: The 302a employs forced convection cooling for thermal management. An on-board thermal sensing circuit regulates fan speed to maintain optimum operating temperature. Balanced / Floating Input: The 302a is supplied with Balanced / Floating inputs. When engaged, this circuitry helps to eliminate "system noise" associated with "ground-loops". It also increases input sensitivity which "widens the scope" of head units for use with the 302a Modular Expansion Ports: The 302a is supplied with three modular port(s). Two of the ports are dedicated to the amplifier and allow you to dock any of Xtant's signal processing modules. The third port is reserved for add signal processing to the RCA line outputs. This true, fully adjustable, one band parametric equalizer provides individual frequency, Q (bandwidth), and gain adjustments. The "Q" ranges from 1 to 10 in value, providing a wide range of adjustment to address the subtle tuning requirements common with most mobile audio systems. 24 DB / OCTAVE CROSSOVER MODULE ­ CM 24X The CM-24X is a 24 dB per octave "Linkwitz - Riley" crossover filter. The CM-24x module improves loudspeaker polar response while its steeper slope provides enhanced system design flexibility. 12 DB / OCTAVE FILTER MODULES ­ CM 12H & CM12L The CM12H and CM12L are 12 dB per Octave "Butterworth" filter networks dedicated to either a High-Pass function (CM12H) or Low-Pass function (CM12L). Each module is designed to be plugged into any accessory port on Xtant's 301a and 302a amplifiers. Frequency adjustment is via a 12 pin plugin resistor SIP (Single In-line Package) and 13 different frequency SIPS are available from your authorized Xtant Dealer. RESISTOR MODULES ­ RM4, RM8, RM12 & RM16 The RM 4, 8, 12 & 16 resistor modules are designed to activates the "passive speaker terminals" on the 302a while providing four different levels of attenuation for the speakers connected to these terminals. The RM 4 module offers 4 dB of attenuation, the RM 8 offers 8 dB of attenuation, the RM 12 offers 12 dB of attenuation and the RM 16 offers 16 dB of attenuation. 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 ­ E v e ry 9 0 Day s 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.
