After three years of developing the MicroZOTL circuit in our MZ2 and identifying the most significant points for performance upgrades, we've consolidated this knowledge in the MicroZOTL Preamplifier. Fulfilling the needs of any reference two-channel speaker system, the MicroZOTL Preamplifier also brings its abilities as a headphone amplifier to a new level. 

New features include:
4 single-ended RCA inputs
1 balanced XLR input using a high-quality Cinemag input transformer
Digitally controlled stepped attenuator with discreet resistors
2 preamp outputs
Tape in/out
Improved power supply compared to the LTA LPS+
Balance control
Fully remote controllable
LED display with adjustable brightness
Ceramic circuit board with low dialectric loss
Upgrades to the most significant capacitors in the audio path
Advanced protection circuit to prevent speaker pops even in the event of a power outage
