Millennia TCL-2 - Millennia equipment is designed and built for those who want their audio reproduction to tell the truth, the whole truth, and nothing but the truth. If you look up the phrase "extremely accurate microphone reproduction," you'll see a picture of the Millennia HV-3 preamp. Now they've applied their expertise to dynamics processing with the TCL-2 Twincom opto-compressor/limiter. The TCL-2 is completely balanced from input to output. No transformers or amplifiers are used to unbalance the signal inside the unit. Tech talk aside, you'll find the TCL-2 in the studios of mastering giants, hundreds of recording studios, and in the rigs of countless artists and engineers.
Ultra-transparent Tube/Solid-state Compressor
The Twincom (TCL-2) is an ultra-transparent, two channel opto-compressor/limiter offering Class-A biased all discrete J-FET solid-state operation or Class-A biased all triode vacuum tube operation at the touch of a button. The TCL-2 (tm) Twincom stereo compressor/limiter with Twin Topology - 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.
Minimalist Audio Signal Path
What is "minimalist?" The Twincom has only one active stage in the audio signal path. Compare this with common textbook compressor designs employing multiple amplifiers in the signal path. Fewer amplifier stages means greater sonic integrity and heightened musical reality. This one amplifier stage is optimized as input buffer, dynamics amplifier, and output driver. Greatly increased musical clarity is achieved as precious audio signals are spared from successively colored amplifier stages.
Entirely Balanced Circuit
The Twincom is also designed as an entirely balanced circuit. In most professional audio gear, balanced input signals become unbalanced by a transformer or electronic circuits, and perhaps rebalanced at the output via similar methods. The Twincom never unbalances. Rather, 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? Most of today's high voltage pro tube gear uses audio transformers. Yet, transformers add coloration to audio signals; coloration which is not conducive to sonic purity. Via innovative design techniques, the Twincom avoids audio transformers entirely. Now, the remarkable musicality of Class-A triode dynamics can be realized 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. Millennia also provides these J-FET amplifiers as the next generation of 990 (Jensen tm) and 2520 (API tm) plug-in-compatible modules. 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. Twin Topology! Both topologies are designed to deliver a musical optimization of their inherent character.
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..).
