About the TLC-1 Deluxe

The McCormack TLC-1 Deluxe is a solid state preamplifier introduced around 1981, designed as a passive line control unit with no gain. It features passive inputs and both passive and buffered outputs (unity gain), allowing users to choose between a pure passive signal path or a buffered low output impedance path. The front panel includes an input selector, tape monitor selectors for two tape decks, balance control, and a high-quality conductive-plastic volume control without detents. The rear panel offers multiple inputs (5 auxiliary and 2 tape monitors) and outputs, including passive and buffered outputs. The buffered outputs use an Analog Devices AD712 dual-op-amp chip, which can be muted via a front-panel switch. The volume control is noted to be touchy at low levels. The unit is highly regarded for its exceptional transparency, natural midrange, and minimal coloration, making it a favorite among audiophiles seeking a neutral and clear preamplifier. It weighs approximately 7 pounds and measures 2 5/8" H x 19" W x 11 3/4" D. The frequency response extends from 1 Hz to 50 kHz (-3 dB points). It is often praised for its musicality and is considered one of the best sounding preamplifiers for its price range, though it lacks a phono stage.
