1) Power Switch - The POWER switch may be configured to operate in the manner best suited to the installa-
tion of the unit; for example, if the DA-16X is installed in a rack with a Master power switch, the unit may be
configured to power on when the Master switch is turned on. Please see the section of this manual entitled
"Internal Adjustments" for details.
Note that the POWER switch LED indicates that the DA-16X is receiving a proper AC input, and is in
Standby. The LED goes out when the DA-16X is powered on.
2) Setup buttons and LED - These buttons are used to modify all settings on the DA-16X. In general, setting
modification is accomplished by :
a) enabling Setup mode by pressing any of the 4 buttons (the Setup LED will light and one parameter
b) using the PREV or NEXT buttons to scroll to the parameter to be modified;
c) using the UP or DOWN buttons to select the desired parameter value.
After Setup mode is enabled, pressing the PREV or NEXT button will cycle through the DA-16X's seven
parameters - CLOCK SOURCE, SAMPLE RATE, WC ratio, OPTICAL format, AES format, INPUT and CAL
mode- and then return to the first parameter. Likewise, pressing the UP or DOWN buttons will cycle through
the values available for the selected parameter. Once a value is selected, it immediately becomes active,
regardless if the LED is flashing to indicate that Setup mode has been enabled.
If the CAL parameter has been selected, pressing and holding either the PREV or NEXT button will allow the
user to enter Channel CAL mode; it's now possible to cycle through channels 1-16 (plus two oscillator set-
tings) in order to make settings to individual channels. Please see page 5 for more details concerning CAL
modes. Figure 1 depicts the parameter cycles of the DA-16X.
