Model Two Rev. 3.01 Software Features

1. Precision Master Word Clock Output capability in all AD and DD operating modes. This
feature greatly reduces audible D/A conversion distortion caused by digital input signal
time base jitter by allowing both the A/D and D/A converters to be clocked by the Model
Two's precision internal clock. The Model Two can also generate or lock to either 1X or 2X
reference clock frequencies in both AD and DD modes. See pages 26-27 for details.
2. Dual clock family operation at multiples of 44.1 kHz or 48 kHz, allowing A/D c o n -
version, D/A conversion and digital processing at 192 kHz, 176.4 kHz, 96 kHz, 88.2 kHz,
48 kHz, and 44.1 kHz. Digital I/O is selectable between single wire, double speed, or dual
wire, single speed AES at 88.2 kHz and 96 kHz. Input and output settings are independent.
3. HDCD for DVD-Audio, including automatic 24-bit, 20-bit, and 16-bit HDCD LSB code
insertion at all sampling frequencies to allow HDCD process detection by HDCD equipped
DVD-Audio playback equipment.
4. 44.1/48 kHz to 88.2/96 kHz and 176.4/192 kHz high resolution HDCD interpolation
filtering to provide very high accuracy for both D/A conversion and high sample rate
processing of 44.1/48 kHz signals.
5. HDCD Limiting, which is identical in function to Peak Extension, except that the
limiting curve is not undone during HDCD decoded playback.
6. DAC-System Optimize, which allows the operation of the Model Two's D/A converters
to be precisely optimized to the performance characteristics of the monitor electronics
and power amplifier being used.
The Model Two has several new Operating Modes and Setup Menus to provide these capa-
bilities. Descriptions of the Operating Modes and Menus are at the following locations:
