Harmonic Bass Alignment™ The 2nd and 3rd order harmonic peaks are
critically aligned to fundamental peaks at low frequencies. This produces
tighter, more accurate bass reproduction.
Drive Delay II™ Amplifier section powers up 2 to 3 seconds after the power
supply eliminating turn-on pops. The turn off process is reversed:
Amplifier section turns off first, followed by the power supply.
Output Clipping Indicators indicate clipping on the output stage of the
amplifier. Monitoring the clipping indicators allows the user to achieve
maximum Sound Pressure Level without clipping the amplifier.
Dynamically Optimized power Grid™ Power grid is evenly distributed
between primary and secondary power supplies, providing greater dynamics
and improved RF filtering.
Chassisink™ All transistors are ideally located and sandwiched between the
circuit board and the heatsink to provide cool efficient amplifier operation.
Differentially Balanced RCA Input eliminates ground loop related noise in
the audio.
Continuously Variable Crossover Network : 12dB/Octave highpass
crossover variable from 50 to 200 Hz and 24dB/Octave lowpass crossover
variable from 40 to 160 Hz.
Flexible Input Level Control allows 300 mV to 5 V input sensitivity.
Symmetrical Discrete Balanced Class A Drive Boards auto-adjust for linear
performance while driving low impedance loads.
Removable Front Spoiler allows for stealth installation of RCA, Balanced
Line, Speaker and Power wiring.
