FEATURES

• TCCHtmThermal Convection Cooled Heatsink. This proprietary design uses a variable speed fan to ensure that the ZXTikeeps its cool when the music gets hot!

• High-current Triple Darlington output stage. This tried and true topology is the standard for outstanding dynamic peak output performance

• TAIMtmTimed Acoustically Integrated Muting. Ensures dead silent turn on & off. No clicks, pops or buzzes

• Tri-lineartmcapability allows simultaneous stereo and bridged operation

• Output current sensing allows the ZXTito automatically optimize the power supply and output stage to reliably operate at impedances as low as 2 ohms bridged or 1 ohm stereo

• Intuitive crossover configuration switch assures easy initial setup

• 24dB per octave, high pass or low pass crossover. Continuously variable from 40 Hz to 8 kHz front and 40 Hz to 800 Hz rear

• Auxiliary outputs route high pass, low pass or full range signals to another amplifier

• Twin-TtmBass Boost circuit provides up to 18dB of boost at 45 Hz

• SuperbritetmTri-LED power-on indicator

• Independent Thermal and Overload protection LED indicators

• Custom formed chassis with unique Titanium finish

• 24kt gold plated power and speaker terminals

• 2-ounce copper, double-sided G10 glass-epoxy printed circuit boards

• Replaceable insulated mounting feet

• Audiophile grade capacitors and 1% tolerance metal film resistors throughout the audio path

• Optional LPL44tmLow Pass Level controller allows the driver to adjust bass volume from the driver’s seat

• Optional RDDPtmRemote Diagnostic Display Panel uses two tri-color LED’s allowing the driver to monitor the amplifier’s battery voltage, power-on, thermal and overload status

• Optional SDTtmSuperior Digital Technology allows the driver to monitor the amplifier’s battery voltage with a vacuum florescent display along with a tri-color LED indicating power-on, thermal and overload status
