When the master power switch on the rear panel is in the "|" (on)
position, pressing this button takes the PDP 3 out of “standby”
mode, turns the Display on, and makes the processor ready to
operate. (See “Rear panel” and “Set-up and installation.”)
2 Standby LED
This LED lights when the PDP 3 is in the standby mode.
3 sampling frequency Display
This Display shows the sampling frequency (expressed in kHz) for
the digital source you selected.
For digital FM, the Display will show 32; for compact disc digital
audio, the Display will show 44; for pre-recorded digital audio
tape, the Display will show 48. If no valid digital source is selected,
or if the selected source is inactive, the Display will show - - .
4 source LEDs
These LEDs light corresponding to the selected digital source.
5 select
Pressing this button selects the digital source, according to the
input connections on the rear panel. (See “Rear panel” and “Set-
up and installation.”)
Only one source at a time may be selected.
When the PDP 3 is taken out of the standby mode, the source last
selected before going into standby will be automatically selected
and the LED above that source will light; for example, source 1.
Pressing the select button at this point would select source 2;
pressing it again would select source 3, and so on. Pressing select
when source 4 is selected again selects source 1.
