digital signals to HDCD 24, 20 or 16-bit, 44.1/48 kHz signals using HDCD decimation.
1. From the Operating Menu, select (SETUP/MODE/44.1_X or 48_X).
2. From the Operating Menu, select (SETUP/PRESETS) and select either preset DD2X-
24 or DD2X-16, depending on the desired output word length.
3. Or, from the Operating Menu, select (SETUP/MODE/MORE.../MORE.../DD88-44 or
DD96-48).
4. From the Operating Menu, select (SETUP/INPUT/FORMAT), then select the digital
input format. 1_WIRE selects single wire, double speed AES. 2_WIRE selects two
wire, single speed AES. The factory presets select two wire, single speed AES input.
5. If two wire was selected, connect the AES channel 1 and 2 output of a 4 channel,
24-bit or 20-bit, 44.1/48kHz digital audio recorder to AES In 1, and the AES
channel 3 and 4 output to AES In 2, or connectthe AES two wire 88.2/96 kHz out
puts of a DAW to AES In 1 and 2.
6. If single wire was selected, connect the double speed AES output of an 88.2/96 kHz
digital recorder or DAW to AES In 1.
7. Connect AES Output 1 or 2 to a digital audio recorder or DAW.
CAUTION: Do not feed a standard STEREO 44.1 kHz or 48 kHz AES signal to either AES
In 1 or 2 when the Model Two is set up for AES two wire input in DD88-44 or DD96-48
Modes. Doing so will cause supersonic spurious energy to appear at the D/A analog
outputs which may damage loudspeakers.
Setup for 44.1/48 kHz to 88.2/96 kHz Interpolation & Word Length Conversion
In DD44-88 or DD48-96 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 88.2/96 kHz signals using high resolution
HDCD interpolation filtering.
1. From the Operating Menu, select (SETUP/MODE/44.1_X or 48_X)
2. From the Operating Menu, select (SETUP/PRESETS) and select preset DD1X-2X.
3. Or, from the Operating Menu, select (SETUP/MODE/MORE.../MORE.../DD44-88 or
DD48-96).
4. Connect a 24-bit, 20-bit, or 16-bit 44.1/48 kHz digital source to the AES 1 Input.
5. From the Operating Menu, select (SETUP/OUTPUT/FORMAT), then select the digital
output format. 1_WIRE selects single wire, double speed AES. 2_WIRE selects two
wire, single speed AES. The factory presets are two wire, single speed AES output.
6. If single wire was selected, connect AES Out 1 or AES Out 2 to the double speed
AES input of an 88.2/96 kHz digital recorder or DAW.
7. If two wire was selected, connect AES Out 1 and 2 to the AES single speed, two wire
inputs of an 88.2/96 kHz digital recorder or DAW.
