Indestructible Military Grade Chassis The Millenia Media TD-1 employs twin topology so you no longer have to choose between tube or solid state front end to get the perfect sound. The TD-1 offers either a 100 percent vacuum tube instrument amp or transparent 100 percent discrete F.E.T. solid state instrument amp all in the same indestructible military grade chassis. These 2 different states are switch selectable and can be musically tuned by using the 3 selectable input impedances. Audiophile Quality Millenia Media's TD-1 is fantastic in any setup thanks to its nine outputs. These include balanced and unbalanced line on XLR and 1/4 " as well as two 1/4 " reamp outputs a balanced transformer output, an audiophile quality headphone output and a direct output. Realistic Feel The TD-1 is well suited for guitars and bass thanks to its speaker soak technology that enables you to run your amps power straight into the TD-1 that gives you the realistic feel and sound of playing live.
