6.3 Settings for Digital Sources
For a digital source, Figure 6-4 shows the connections required. Set the controls and switches
on the front panel as follows:
1. After all rear-panel input and output connections have been made, apply power to the 601
and depress the
POWER switch. When the display shows program number 1 , proceed to the
next step.
2. Depress the
GLOBAL switch once. The display reads GAIn . Rotate the Wheel to set the digital
input gain to
0 .
3. Depress the
GLOBAL switch again. The display reads Pd-- or PAd . Since we are using the
digital input, this parameter is unimportant.
4. Depress the
GLOBAL switch again. The display reads InP . Rotating the Wheel selects the
input source as indicated by the
DIGITAL/MIC/LINE LEDs. The input possibilities are: digital,
mic, mic + line (mic/line mix), line. Rotate the Wheel until the
DIGITAL IN/SYNC LED
illuminates (steady or flashing).
5. Depress the
GLOBAL switch again. The display reads CL-- . The clock/sample-rate reference is
the external digital signal. Refer to Chapter 4 for additional information.
6. Depress the Global switch again. The display reads
nP-- (not protected) or Prt (protected).
Select memory protection as required.
7. Depress the level switch. The display reads
L 0.0 . If not, rotate the Wheel until the display
reads
L 0.0 . This sets the output gain to 0 dB.
Set the input level by accessing the global
gAIn setting from the GLOBAL switch. This parameter
is the digital input gain. Increase the
gAIn setting as required so that the -2 dB LED in the
H
EADROOM display illuminates. Since the red CLIPPING LED is driven from the analog inputs, it
should never illuminate. The 601 should now pass signal.
