Crestron CNX-PAD8A Professional Audio Distribution Processor

Professional Audio Distribution

Processor: CNX-PAD8A

Description

Functional Description

The Crestron Professional Audio Distribution Processor, CNX-PAD8A is an

enhanced version of Crestron's professional high-end audio distribution system. It

delivers audio from up to eight sources into as many as eight separate rooms and can

be expanded with additional CNX-PAD8A chassis to 32 rooms (using the optional

Audio Switcher Bussing Kit). Powered by a Crestron control system, the

CNX-PAD8A can be programmed to select any available audio source, choose a

room destination, and distribute a pre-amplified signal to as many as eight room

amplifiers, each of which can be chosen according to its application. A general

application of the CNX-PAD8A is shown on the next page. In addition, the

CNX-PAD8A provides the mixing of stereo sources to mono. Any Crestron user

interface – from keypad to touchpanel – provides access and control to the

CNX-PAD8A's functions. The CNX-PAD8A should typically be installed with the

Crestron amplifier (i.e., CNAMPX-16x60). The table after this paragraph provides a

summary of the enhancements associated with the CNX-PAD8A.

Physical Description

The CNX-PAD8A 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. There is also one LED on the back of the unit. 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: There are no RJ-11 connectors on this product.

Use the supplied 4-pin network connector as described in "Network Wiring" on page

9 and connect the control system and other peripherals to this port.

(Chassis Ground)

Use this chassis screw to connect the audio source(s) common ground(s) to the

CNX-PAD8A.

SOURCES 1 - 8

Each of the eight sets of four RCA connectors is used to connect the independent

audio sources to the CNX-PAD8A. 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-PAD8As 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.

CNX-PAD8A Indicators

There are 11 LED indicators primarily located on the front panel of the

CNX-PAD8A (one of the 11indicators is on the back panel). Each LED has a silk-

screened label. Refer to the illustration and descriptions that follow.

CNX-PAD8A Indicators

CRESTRON

PWR (Power)

This LED illuminates when 24 volts from the network is supplied to the

CNX-PAD8A.

NET

This LED illuminates when communication between the control system and the

CNX-PAD8A is established (the unit is polled on the network). Illumination

indicates that the SIMPL Windows program currently loaded has a network device

defined at the same NET ID as the CNX-PAD8A. The LED flashes when

communication with the processor occurs.

ROOMS 1 – 8

These eight LEDs illuminate when the corresponding room is enabled to receive

audio from the CNX-PAD8A.

SETUP

This LED is the lone indicator on the back panel. The purpose of the LED is

intended for future use and was not defined at the time of printing.

CNX-PAD8A Pushbuttons

There is one pushbutton on the CNX-PAD8A (rear panel). The SETUP pushbutton is

for future use and was not defined at the time of printing.

1 The product is supported in the Crestron Application Builder Software, both in the Residential and

Commercial versions. Contact Crestron Customer Service for licensing details.

2 The latest software versions can be obtained from the What's New page (SIMPL Windows) or

Downloads page (SIMPLWIN Library) of the Crestron website (www.crestron.com). New users are

required to register in order to obtain access to the FTP site.

For programming purposes, the CNX-PAD8A is completely substitutable for the CNX-PAD8.

3 Crestron 2-Series control systems include the AV2, AV2 with Card Cage, CP2, CP2E, PAC2,

PAC2M, PRO2, and RACK2.

4 Filenames for 2-Series control system update files have a CUZ extension and can be obtained from

the What's New page (Control Systems Update Files section) or Downloads page (OPSYS Library)

of the Crestron website.

5 CNX upgrade files are required for either CNMSX-AV/Pro or CNRACKX/-DP. Filenames for CNX

upgrade files have a UPZ extension and ST-CP files are in one EXE or zipped UPZ file. All can be

obtained from the What's New page (Control Systems Update Files section) or Downloads page

(OPSYS Library) of the Crestron website (www.crestron.com). Update files are specifically

designed for certain control systems. If an update file is loaded into a control system other than the

device for which it was intended, it may lockup the control system, which would then have to be

returned to Crestron. Update files with an "S" designator are for the ST-CP, "V" designator for

CEN/CN-TVAV, "W" for CNRACKX-DP, and "X" for CNMSX-AV/Pro control systems. Control

systems are able to recognize and reject incorrect update files. However, when updating control

systems, do not ignore Crestron Viewport warning prompts or messages.
