Twin Topology Class A Recording Channel

Millennia Media

Millennia TD-1 DI Detail Demo and Review -- Part 2

The Millennia TD1 Twin Topology (tube/solid state) DI/Preamp is explored in Part 2 of this 2-part series, as a DI (with alternate impedances), EQ, Tube and Solid State modes (for the mic pre and DI), Speaker Soak function, and is also used as a straight Microphone preamp (from the world-renowned HV3 series of Millennia mic preamps) in this in depth look of the rich features of this amazing little tonal device. The Millennia TD-1's sound quality, build quality, and overall feature-set make this device a truly world-class studio workhorse piece of equipment.
