The 24-Bit/192-kHz precision upsampler operates on all digital audio signals. The D2’s DACs also incorporate 128X oversampling to increase the sample rate to 24.576 MHz, ensuring the best phase and frequency response possible. Measurable results reflect exceptionally flat frequency response and THD+N in the upper frequencies. This is up to twenty times lower than some of the best high-end outboard DACs, resulting in a much higher level of transparency for multichannel music and movies. Sonic performance is astounding. Smoother high-frequency response, superior detail, and better image focus - a far more transparent window on the original performance. |

Anthem’s Own Design! Two dual-core digital signal processing (DSP) engines, our own DSP design, offer a total of 800 MIPS to allow decoding of the new HD audio standards: Dolby Digital Plus, Dolby TrueHD, DTS-HD High-Resolution Audio and DTS-HD Master Audio. More than enough processing power to handle even the most complex program material with matchless precision. |
| • |
Triple 4 Mbit 8ns external memory is large enough to ensure that the DSP engines never run out of resources. |

Unparalleled analog-to-digital and digital-to-analog conversion eliminates noise in the 20 to 80-kHz frequency band thanks to the high quality of our ADC and DAC designs:
Analog-to-Digital Conversion (ADC): |
- |
Capable of up to 24-bit x 192-kHz resolution |
- |
Six stereo analog attenuators - one for each channel of
the 6-channel input, promote greater dynamic range and
an impressive reduction in distortion |
Digital-to-Analog Conversion (DAC): |
- |
Converters operate at their full 24-bit x 192-kHz resolution |
- |
Switched-capacitor output filters significantly reduce the
DAC’s sensitivity to rapid fluctuations in bit rate |
- |
The built-in state-of-the-art upsampler allows the DACs
to run at the highest speed (192 kHz) regardless of the
incoming digital bitstream, and with extremely low back
ground noise up to almost 100 kHz |
- |
High-accuracy clock generator (49.152 MHz, +/-0.001%)
eliminates the potential for errors in timing, thereby
contributing to a significant reduction in the distortion
common in D/A conversion |
