Model Two HDCD User's Manual
AC power for the Model Two should be supplied by the same circuit and preferably the same
power outlet group as the AC power source for other equipment, such as analog tape
machines or consoles, whose outputs will be connected to the Model Two's analog inputs.
This will minimize the possibility of ground loops.

Power Up

Press the Power Switch on the Processor front panel to turn on the Processor and Power
Supply. The System Status Indicator will be lit orange, the A/D and D/A Clock Indicators
will be lit green, and the HDCD Indicator will be lit purple. The Graphic Display will mo-
mentarily display the following messages: "HDCD BOOT VERSION", "STARTING HDCD..." and
"Loading DSP#1.." through "#8". The System and Clock Indicators will then usually indi-
cate normal operation (green) and the HDCD Indicator will go dark or remain lit depending
on system set up. Power up is complete when an Operating Menu appears on the Graphic
Display similar to the one shown below.
At power up all settings will remain as they were prior to power off. From the Operating
Menu, all Processor functions are accessible. Function buttons (see page 17) are used to
navigate through menus and select items within the menus. Selected items become active
by pressing the ENTER button, or by toggling between selections. At any time, the Operat-
ing Menu can be accessed by pressing and holding the MENU UP button.

Setting Analog Connector Pin Polarity

The Processor allows the XLR connector pin polarity of the analog input and outputs to be
set to either pin 2 or 3 hot. The factory default setting is pin 2 hot. To verify or change the
polarity setting, go to the Analog Polarity Menu. From the Operating Menu select (SETUP/
MORE.../SYSTEM/POLARTY). To change, use the function buttons to select either PIN2HOT
or PIN3HOT, and press ENTER to activate. For additional information, see the Analog Polar-
ity Menu on page 60.
