Design
The T-110CS uses four 18-bit MMB (Multiple Multi-Bit) D/A converters in parallel and features an 18-bit, 8x oversampling digital filter. It integrates VITABI and PCM composite LSI chips for signal processing and includes a built-in Core Tech type scramble decoder. The analog outputs use fully balanced XLR and unbalanced RCA connectors, with the balanced circuit floating from ground. Two digital outputs—Toslink optical and coaxial RCA—are provided. The unit includes an antenna adjustment switch and antenna input level display, and employs a third-order Butterworth GIC (Generalized Immittance Converter) active filter.
