1 standby
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.
6 emphasis LED
This LED lights when the PDP 3 detects recording pre-emphasis in a
digital program, and subsequently employs its de-emphasis
circuitry.
NOTE: The de-emphasis circuitry of the Proceed PDP 3 is designed
to be compatible with all known digital standards. Under certain
conditions, however, the emphasis LED will light in error (that is,
when the digital program doesn’t contain recording preemphasis).
This isn’t a malfunction of the PDP 3. Rather, it’s the result of
incorrect signals generated by the program source’s transport.
Depending on your transport and how you operate it, you may
never see this condition. Even when the condition exists, it has no
effect on sonic quality.

1 master power
This switch turns the PDP 3 on and off. The switch must be in the "|"
(on) position for the processor to operate. (See "Set-up and
installation.")
NEVER operate the master power switch without first making sure
that power is turned off to your receiver, integrated amplifier, or
preamplifier/power amplifier.
2 Single-ended analog outputs
These outputs provide single-ended analog audio (via cables
equipped with RCA-type connectors) to a receiver, integrated
amplifier, or preamplifier equipped with unbalanced inputs. Most
components accept this type of output. (See "Set-up and
installation.")
3 Balanced analog outputs
These outputs provide balanced analog audio (via cables
equipped with XLR-type connectors) to a preamplifier, integrated
amplifier, or receiver equipped with balanced inputs. (See "Set-up
and installation.")
4 digital out
This output provides digital audio (via a cable equipped with
RCA-type connectors) to the digital input of a receiver,
integrated amplifier, preamplifier, or digital processor. (See "Setup and installation.")
5 source 1 digital input
This input accepts digital audio (via an optical cable equipped
with TOSLINK-type connectors) from the digital output of a digital
FM tuner, compact disc player, or digital audio tape recorder.
4
6 source 2 digital input
This input accepts digital audio (via an optical cable equipped
with ST-type connectors) from the digital output of a digital FM
tuner, compact disc player, or digital audio tape recorder.
7 source 3 digital input
This input accepts digital audio (via a cable equipped with RCAtype connectors) from the digital output of a digital FM tuner,
compact disc player, or digital audio tape recorder.
8 source 4 digital input
This input accepts digital audio (via a cable equipped with XLRtype connectors) from the digital output of a digital FM tuner,
compact disc player, or digital audio tape recorder.
9 AC power cord
This cord supplies AC power to the PDP 3. (See "Set-up and
installation.")
10 Fuse
This holder contains the main fuse for the PDP 3. If the fuse ever
needs to be replaced, contact your Proceed dealer.

Unpacking
Carefully open the shipping carton and remove the contents. You
should have:
■ Proceed PDP 3
■ Owner’s manual
■ Four spikes
■ Hex key
Save the shipping carton and all packing material. Though it may be
inconvenient to store, it’ll come in handy for shipping if you move, or if
the unit needs to be shipped for service.
Locate the serial number (on the back panel), and record it here:
■ Serial Number:
Keep your sales receipt where you can find it. You’ll need to show it
for any service during the warranty period. Take a moment now to
record some information from the receipt:
■ Date of purchase:
■ Proceed dealer:
■ Dealer’s address:
■ Dealer’s telephone number:
