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
P
OWER
switch. When the display shows program number
1
, proceed to the
next step.
2. Depress
the
G
LOBAL
switch once. The display reads
GAIn
. Rotate the Wheel to set the digital
input gain to
0
.
3. Depress
the
G
LOBAL
switch again. The display reads
Pd--
or
PAd
. Since we are using the
digital input, this parameter is unimportant.
4. Depress
the
G
LOBAL
switch again. The display reads
InP
. Rotating the Wheel selects the
input source as indicated by the
D
IGITAL
/M
IC
/L
INE
LEDs. The input possibilities are: digital,
mic, mic + line (mic/line mix), line. Rotate the Wheel until the
D
IGITAL
I
N
/S
YNC
LED
illuminates (steady or flashing).
5. Depress
the
G
LOBAL
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
G
LOBAL
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
C
LIPPING
LED is driven from the analog inputs, it
should never illuminate. The 601 should now pass signal.
