Setup & Operation
Once the Model Two is set up for 44.1/48 kHz to 88.2/96 kHz interpolation, other param-
eters such as Digital Input HDCD Code Detect, Digital Input HDCD_16 Decoding, Digital
Output Word Length, etc. may be changed as desired. For information, see pages 46-56.
Setup for 176.4/192 kHz to 44.1/48 kHz Decimation & Word Length Conversion
In DD176-44 or DD192-48 Modes, the Model Two converts 24-bit or 20-bit, 176/192 kHz
digital signals to HDCD 24-bit, 24-bit, or 16-bit, 44.1/48 kHz signals using HDCD adaptive
filter decimation.
1.
From the Operating Menu, select (SETUP/MODE/44.1_X or 48_X)
2.
Connect AES In 1 and 2 to the double speed AES outputs 1 and 2 of a 176.4/192
kHz digital audio recorder or DAW.
3.
Connect AES Output 1 or 2 to a digital audio recorder or DAW.
4.
From the Operating Menu, select (SETUP/PRESETS) and select either preset DD4X-
24 or DD4X-16, depending on the desired output word length.
5.
Or, from the Operating Menu, select (SETUP/MODE/MORE.../MORE.../MORE.../DD176-
44 or DD192-48).
6.
From the Operating Menu, select (SETUP/OUTPUT/OUT_1), and select the word length.
Setup for 44.1/48 kHz to 176.4/192 kHz Interpolation & Word Length Conversion
In DD44-176 or DD48-192 Modes, the Model Two converts 24-bit, 20-bit, or 16-bit, 44.1/
48 kHz signals to HDCD 24-bit, 20-bit or 16-bit 176/192 kHz signals using high resolution
HDCD interpolation filtering.
1.
From the Operating Menu, select (SETUP/MODE/44.1_X or 48_X)
2.
Connect a 24-bit, 20-bit, or 16-bit 44.1/48 kHz digital source to the AES 1 Input.
3. Connect AES Out 1 and 2 to the AES double speed, two wire inputs of a 176/192kHz
digital recorder or DAW.
4.
From the Operating Menu, select (SETUP/PRESETS) and select preset DD1X-4X.
5.
Or, from the Operating Menu, select (SETUP/MODE/MORE.../MORE.../MORE.../MORE.../
DD44-176 or DD48-192).
Once the Model Two is set up for 44.1/48 kHz to 176.4/192 kHz interpolation, other
parameters such as Digital Input HDCD Code Detect, Digital Input HDCD_16 Decoding,
Digital Output Word Length, etc. may be changed as desired. For more information, see
pages 47-58.
DAC-Monitoring System Performance Optimization
The Model Two has advanced DAC optimization capabilities designed to provide the high-
est possible fidelity with different types of monitoring electronics and power amplifiers.
Specific DAC dithers are provided for 44.1/48 kHz (1X) and 88.2/96/176.4/192 kHz (2X/
