Millennia TCL-2 Twincom Stereo Compressor / Limiter
The Millennia TCL-2 Twincom is an ultratransparent, 2-channel opto-compressor/limiter. The Twincom delivers Class-A biased all-discrete J-FET solid-state operation or Class-A biased all-triode vacuum tube operation at the touch of a switch.

The TCL-2 Twincom stereo compressor/limiter with Twin Topology is Millennia's innovative new merging of vacuum tube and solid state circuit topologies. A front panel switch selects between a complete vacuum tube audio path or a fully discrete solid-state audio path - in the same chassis. Both circuit topologies are entirely transformerless, high voltage, and minimalist.

The Twincom has only one active stage in the audio signal path for greater sonic integrity and heightened musical reality. This stage is optimized as an input buffer, dynamics amplifier, and output driver. Greatly increased musical clarity is achieved as precious audio signals are spared from successively colored amplifier stages.

The Twincom is also designed as an entirely balanced circuit. The balanced input signal remains balanced from input to output, avoiding the need for audio transformers or additional amplifiers in the signal path.

Why transformerless? Transformers add coloration to audio signals; coloration which is not conducive to sonic purity. Via innovative design techniques, the Twincom avoids audio transformers entirely, allowing the remarkable musicality of Class-A triode dynamics without the unavoidable sonic artifacts common to signal path transformers.

The solid-state aspect of Twin Topology consists of 100% Class-A all discrete J-FET (field effect transistor) amplifiers. The vacuum tube aspect of Twin Topology employs 300 volt, 100% Class A, hand-tested and selected triode vacuum tubes. To use the vacuum tube amplifier, simply press a front panel switch. To use the solid-state amplifier, press the switch again. Both topologies are designed to deliver musical optimization with individual character.

The Twincom offers illuminated push-button switches, machined aluminum knobs, extruded and radiused face plate (nearly 3/8" thick), and a stylish "TT" logo deeply engraved into every panel.

The Twincom employs exquisite high voltage amplifiers free of transformer coupling, carefully designed around the finest grades of passive components (Vishay pots, Roederstein resistors, Wima and Electrocube capacitors, Neglex OFC audio cabling, gold tube connectors and relay contacts, silver Teflon power wiring, large Sifam true audio level meters, etc.).
