FEATURES
•TCCHtm Thermal Convection Cooled Heatsink. This proprietary design uses a variable speed fan to ensure that the ZXTi keeps 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
•TAIMtm Timed Acoustically Integrated Muting. Ensures dead silent turn on & off. No clicks, pops or buzzes
•Tri-lineartm capability allows simultaneous stereo and bridged operation
•Output current sensing allows the ZXTi to 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-Ttm Bass Boost circuit provides up to 18dB of boost at 45 Hz
•Superbritetm Tri-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 LPL44tm Low Pass Level controller allows the driver to adjust bass volume from the driver’s seat
•Optional RDDPtm Remote 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 SDTtm Superior 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
