Crestron CNX-PAD8 Professional Audio Distribution Processor
Professional Audio Distribution
Processor: CNX-PAD8
Description
Functional Description
The Crestron Professional Audio Distribution Processor, CNX-PAD8, controls the
selection of, volume and distribution of up to eight audio sources. It can select any
available audio source, preamplifies then distributes the audio to up to eight room
amplifiers (not supplied). It can be used with the SmarTouch STS (ST-CP) or as part
of a Cresnet system. When used with the SmarTouch STS (ST-CP), power is
supplied by an optional external power pack. When used as part of a Cresnet system,
the system supplies operating.
Optional Source and Numeric Keypads may be added to the individual rooms to
control the CNX-PAD8. Refer to the CN-WP12 Operations & Installation Guide
(latest revision of Doc. 5788) for further information.
Additionally, the outputs may be expanded to 32 rooms by using the optional Audio
Switcher Bussing Kit to daisy-chain up to three additional CNX-PAD8s. Refer to the
CNX-ASBK Operations & Installation Guide (latest revision of Doc. 8143) for
further information.
Physical Description
The CNX-PAD8 is housed in a black enclosure with silk-screened labels on the front
and rear panels. On the front of the unit there are 10 LEDs for indicating the unit’s
current status. All connections are made to the back of the unit. Refer to the physical
view shown after these paragraphs.
Two mounting ears are provided for rack mounting and, for table-top mounting or
stacking, four square rubber feet are provided. These feet are to be attached on the
base of the unit for stability and to prevent slippage.

NOTE: If the CNX-PAD8 is part of the Cresnet system, use of this port is optional.
This DC power socket connector is used to supply power via an external AC power
pack. Crestron recommends specific power packs for its network devices. The
recommended power pack for the CNX-PAD8 is Crestron part number PW-2410RU
and is sold separately. If an external power pack other than this Crestron model is
obtained, verify that it meets the required specifications and polarity as shown after
this paragraph.

The 4-pin network connector is used to connect the CNX-PAD8 to the Cresnet
system. When the unit is connected to the system, power can be provided via the
connection and the external power pack is not required. Review the Network
Interconnection Diagram (latest revision of Doc. 5411).
The two 6-position RJ11 modular jacks are pass-through connectors that are also
used to connect the unit to either the SmarTouch STS (ST-CP) or Cresnet system.
The two modular jacks are available so that network units can be daisy-chained
together. Review Network Modular Cable Requirements (latest revision of Doc.
5682).
NOTE: Most 4-conductor phone cables are wired in a crisscross fashion and are not
compatible with Crestron equipment.
If an external power pack is attached when the CNX-PAD8 is part of the Cresnet
system, power is drawn from the power pack. The unit does not load the network
power, but the network power remains chained for additional network devices that
are connected.
G (Chassis Ground)
Use this chassis screw to connect the audio source(s) common ground(s) to the
CNX-PAD8.
SOURCE 1 - 8
Each of the eight sets of four RCA connectors is used to connect the independent
audio sources to the CNX-PAD8. Of each set, two of the connectors are used for the
left and right audio channels and the remaining two connectors are parallel stereo
loop-throughs.
The eight rectangular blanks (labeled 1-2, 3-4, 5-6, and 7-8) are used with the
optional Audio Switcher Bussing Kit. The kit contains a printed circuit board with
eight connectors that when installed, is used to daisy-chain three additional
CNX-PAD8s to provide up to a total of 32 room outputs. Refer to the latest revision
of the CNX-ASBK Operations & Installation Guide (Doc. 8143) for further
information.
ROOMS 1 – 8
These eight pair of RCA jacks output the pre-amplified audio to the corresponding
room(s) amplifier(s). Each room output contains left and right audio channels.
