MICRO SEIKI CL-M2DC

The Micro Seiki CL-M2DC is a high-end solid-state stereo preamplifier that was introduced by Micro Seiki Corp. in Japan during the late 1970s. The preamplifier is designed to connect to a turntable and amplifies a very low signal from a cartridge to a level that is suitable for use with a power amplifier or a receiver.

The CL-M2DC featured an advanced circuit design and high-quality components, such as low-noise metal film resistors and polypropylene capacitors, to ensure superior sound quality. The preamplifier circuitry consisted of two boards, each measuring 14cm x 9cm. The main board had a hybrid layout with high-quality transistors and an inverting non-feedback circuit.

The unit included precise RIAA EQ curve compensation to ensure highly accurate reproduction of stereo sound from vinyl records. It also offered a range of advanced features, such as a variable impedance matching circuit, a subsonic filter, and a mute circuit.

The CL-M2DC also featured a unique power supply system with a dual DC power supply circuit that minimized noise and distortion in the audio signal. The preamplifier was housed in an elegant rosewood case with a clear acrylic top panel that provided clear views of the interior circuit boards.

Overall, the Micro Seiki CL-M2DC was an exceptional solid-state preamplifier with a high level of sonic accuracy and advanced features. Its stylish design and superior performance made it a highly sought-after unit among turntable enthusiasts and audiophiles.
