Advanced Computerized Protection Circuitry - improved protection circuitry, for fewer failures. When the protection circuit is activated, the amp will turn off.

Larger Heatsink - each model "grew up" by 1 to 2 inches with substantially more mass. Greater cooling capabilities, and longer initial time to thermal.

New Thermal Pads Under MOSFETS - because silicon grease, formerly used under the MOSFETS, broke down over time and spilled out onto circuit board, we replaced it with polymer thermal pads that offer better transfer of heat from MOSFET to the heatsink. Over time, the polymer actually fills in the pores, creating an even tighter seal. This improvement offers a greater degree of consistency in manufacture for better product reliability.

8-Volt RMS Input - this Large Signal capability allows better integration with high voltage output source units, increased dynamic range and better Signal-to-Noise ratio in the system. 2 {2 U" z; m5 `" H
Continuously Variable Crossover - this allows the user to adjust the crossover frequency from 40Hz to 175Hz with a high or low pass configuration, including adjustable crossover slope from 12db - 18db/Octave.

8 Y/ D1 {2 u' Y) S) b4 @$ q: C7 }Reverse Outputs - when the user selects the highpass setting on the crossover, a complimentary lowpass signal is passed through the RCA outputs, and vice-versa. Crossover frequency of the RCA outputs is determined by the frequency setting on the crossover. This makes it much easier to design multi-amplifier systems. 8 a: }( Q, o) z/ ~) d
