Operating Modes - Pacific Microsonics HDCD Model Two User Manual

Setup & Operation

Operating Modes

The Model Two has thirteen Operating Modes that operate at either multiples of 44.1 kHz
or multiples of 48 kHz, depending upon whether a base sample rate of 44.1_X or 48_X is
selected in the 44.1/48 Base Sample Rate Menu.
NOTE: The Operating Modes listed below and described on the following pages appear
in the Operating Mode Menus if the 44.1_X base sample rate is selected. If 48_X is
selected, the Operating Modes remain the same, except multiples of 48 replace 44.1.
1. AD_44.1 (44.1 kHz, 24, 20, and 16-bit A/D conversion, 16-bit amplitude encoding )
2. DD_44-44 (44.1 kHz, 24, 20, and 16-bit word length conversion, level adjustment,
HDCD 16-bit amplitude encoding and decoding)
3. AD+DD44 (AD_44.1 A/D conversion cascaded with DD44-44 digital processing)
4. AD_88.2 (88.2 kHz, 24, 20, and 16-bit A/D conversion)
5. DD88-44 (88.2 kHz to 44.1 kHz sampling frequency conversion, 24, 20, and 16-bit
word length conversion, level adjust, and HDCD 16-bit amplitude encoding)
6. DD44-88 (44.1 kHz to 88.2 kHz sampling frequency conversion, 24, 20, and 16-bit
word length conversion, level adjustment, and HDCD 16-bit amplitude decoding)
7. DD88-88 (88.2 kHz, 24, 20, and 16-bit word length conversion, level adjustment,
and HDCD LSB code insertion)
8. AD176.4 (176.4 kHz, 24, 20, and 16-bit A/D conversion)
9. DD176.4 (176.4 kHz, 24, 20, and 16-bit word length conversion, level adjustment,
and HDCD LSB code insertion)
10. DD176-88 (176.4 kHz to 88.2 kHz sampling frequency conversion, 24, 20, and 16-bit
word length conversion, level adjust, and HDCD LSB code insertion)
11. DD176-44 (176.4 kHz to 44.1 kHz sampling frequency conversion, 24, 20, and 16-bit
word length conversion, level adjust, and HDCD 16-bit amplitude encoding)
12. DD88-176 (88.2 kHz to 176.4 kHz sampling frequency conversion, 24, 20, and 16-bit
word length conversion, level adjustment, and HDCD LSB code insertion)
13. DD44-176 (44.1 kHz to 176.4 kHz sampling frequency conversion, 24, 20, and 16-bit
word length conversion, level adjustment, and HDCD 16-bit amplitude decoding)
44.1 kHz or 48 kHz base sample rates are selected in the 44.1/48 Base Sample Rate Menu
(SETUP/MODE/44.1_X or 48_X).
Operating Modes are selected in the Operating Mode Menus (SETUP/MODE/MORE...). Each
Operating Mode has specific features that are described below and shown in the Menu Tree
on page 40. All metering functions and analog signal monitoring are available in all Oper-
ating Modes. Factory Presets that use an Operating Mode are listed at the end of the
mode's description. Presets are selected in the Recall Presets Menu (SETUP/PRESETS).
