Accuphase T-110CS

Commentary

CS-PCM tuner equipped with MMB type D/A converter.

Equipped with an MMB (Multiple Multi-Bit) D/A converter that boasts excellent performance and sound quality.
This D/A converter drives four selected 18-bit D/A converters in parallel to improve performance. The output of an 8-times oversampling digital filter is input in parallel to each converter and added immediately after D/A conversion. This improves performance at all frequencies and all signal levels regardless of signal frequency or level.
The parallel drive of the MMB method is not a simple parallel connection. Each of the D/A converters operates independently, and each D/A converter operates completely independently. Therefore, phase control is heavy at high frequencies.
The T-110CS achieves ideal phase matching by carefully selecting converter elements and improving the approximation of layout and wiring patterns.

The digital filter is equipped with an 18-bit 8 x oversampling digital filter.
The digital filter raises the input digital signal to an integer multiple to keep it far from the music signal, and lowers the order of the analog filter in the latter stage to suppress phase rotation.

The digital B-mode of CS-PCM satellite broadcasting uses a sampling frequency of 48 kHz and a 16-bit linear quantization method. It exceeds the level of CD and boasts high sound quality almost equivalent to that of DAT.
In addition, you can enjoy a variety of programs with 12 channels of specialized broadcasting by genre and unique channel organization that you cannot listen to in other media.

The PCM tuner is equipped with highly integrated VITABI (Viterbi) composite LSI and PCM composite LSI.

Equipped with an antenna adjustment switch for easy antenna adjustment and an antenna input level display function.
Adjust the antenna so that this level display becomes the maximum point, and when it reaches the receivable level or higher, it becomes playable.

The active filter uses a GIC (Generalized Immissance Converter) third order Butterworth filter with low phase rotation.
This circuit provides excellent sound quality because the phase characteristic is slow and the signal does not pass through the active element in the passband.

Two digital output terminals, Toslink and Coaxial RCA, are mounted for connection with digital devices.
Direct digital recording is possible by connecting a digital recorder such as DAT.

The analog outputs are equipped with XLR-type balanced connectors and RCA-type unbalanced connectors.
The balanced output consists of a fully balanced circuit floating from ground, and it is also possible to eliminate noise induced by external noise during transmission to prevent degradation of sound quality.

It has a built-in Core Tech type scramble decoder.

Compatible with commercially available CS broadcasting antenna (local oscillation frequency of converter is 11.2 GHz).
