[. . . ] Water and Moisture Install all Xtant amplifiers and accessories in a location free of moisture or exposure to water. 4 The 301a is a 300 Watt, mono (one channel) amplifier designed to provide high power, exceptional flexibility and outstanding performance in an all-in-one package. The 301a can drive a complex speaker system or, be used to create a highpowered, bi-amplified, three-channel system when paired with Xtant's 302a stereo amplifier. The on-board "Balanced Line Inputs" will accept a wide range of input signals ­ from your OEM Factory head-unit to the latest in aftermarket CD head-unit technology. The "Balanced Line" circuitry also helps eliminate noise (alternator whine) induced into the signal cables. As with all Xtant amplifiers, the 301a 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 301a employs forced convection cooling for thermal management. An onboard thermal sensing circuit regulates fan speed to maintain optimum operating temperature. PWM Power Supply: All Xtant amplifiers feature a fully regulated, Pulse Width Modulated power supply. This supply technology provides consistent output performance even when battery voltage is less than optimum. Balanced / Floating Input: The 301a is supplied with Balanced / Floating inputs. When engaged, this circuitry helps to eliminate "system noise" associated with "ground-loops". 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. 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.
