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
