The Titanium or TI-series carries out the tradition of our sound quality and brute power coupled with many on board analog processing features.

Over time the TI amplifiers have been reduced in size without sacrificing power and ergonomics. The current Ti amplifiers are the definition of power and compactness and can be mounted just about anywhere and they have the power levels never seen in this class of product.

The new IR Class-D technology ahs allowed us to use this full range chip in all models. The post filter feedback circuit, Audiophile OP-AMPS and Balanced Differential inputs allow these new amplifiers to have immeasurable music reproduction that rival some of the best Class A/B Amplifiers

The low EMI circuit , ADAPT power management systems and the Thermal Rollback circuit are just the things needed to provide maximum efficiency and lower operating temperatures.
