Product Infomation


Air Tight ATE-2001 Reference Preamplifier features

ㆍMeticulous hand wiring without PCB in all signal paths
ㆍ1.6mm thick steel plate to shield all of the internal and external vibrations
ㆍHigh mass solid brass attenuator pot that is resistant to vibrations, offering smoothest operational touch with utmost accuracy
ㆍOutput stage composed of a low-impedance, high output SRPP circuit that assures stable function of NF circuitry throughout wide bandwidth
ㆍExclusive on-board step-up transformer by My Sonic Lab, featuring high quality core and wire
ㆍA 6DJ8 single stage flat amp, designed as a no NFb SRPP circuit, that sends stable output signals under low impedance even when the attenuator is activated
ㆍ3 line inputs and 3 sets of phono inputs that enable you to use 3 different cartridges/tonearms (2 MCs and 1 MM) for versatile listening pleasure
