Professional Audio Distribution
Processor: CNX-BIPAD8
Introduction
Features and Functions
The Crestron Bi-Directional Professional Audio Distribution Processor,
CNX-BIPAD8, is a second-generation product in Crestron’s audio distribution
product line. The unit is an 8-channel preamplifier that has all of the capabilities of
the CNX-PAD8A product plus the ability to route balanced line audio to and from
remote locations utilizing low cost CAT5 cables and Crestron’s CNXRMCLV,
C2N-DAP8RC, or C2N-DAP8 room boxes. The Cresnet system supplies power to
the unit.
Functional Summary
The CNX-BIPAD8 controls the selection of up to 24 stereo audio sources, and then
distributes the audio to up to eight room amplifiers or Crestron room control boxes.
The unit’s sixteen stereo head end audio inputs are RCA type connectors with loop
through. These inputs plus the eight additional CAT5 stereo inputs pass through a
stereo 24x8 cross-point switch. Each output of the cross-point switch goes to a
differential driver to the CAT5 connectors. The same cross-point outputs also go to
the CNX-BIPAD8 preamplifiers and mute relays before they go to the RCA output
connectors. The cross point switch makes it possible to route any of the 24 audio
• 16 line level/unbalanced stereo source inputs (L/R audio) plus
loop-through
• 8 CAT5 bi-directional inputs and outputs for professional-grade
balanced audio to/from remote locations, using CNXRMCLV or
C2N-DAP8/C2N-DAP8RC local room boxes
• 8 RCA outputs with built-in volume/tone preamplifiers and mute
relays
• Built-in 24x8 stereo crosspoint switch
• Input level compensation adjustments
• Daisy-chaining for distribution up to 32 Rooms

inputs to any of the eight outputs. The following simplified diagram illustrates the
internal signal routing.
Simplified Audio Signal Routing
Up to four units can be daisy-chained via the RCA loop-through connectors to
extend distribution to up to 32 rooms.
The CNX-BIPAD8 preamplifier circuits provide the following controls for each of
the eight RCA outputs:
• Loudness — Activates the loudness function, commonly found on stereo
amplifiers, to boost low- and high-frequency signals at low volume settings
to compensate for natural hearing limitations at lower volume levels.
• Volume — Sets minimum and maximum volume levels and controls the
relative audio level within that range.
• Balance, Bass, and Treble — Specifies levels for these settings relative to a
50% neutral or balanced signal.
• Mono — Changes the audio setting from stereo to mono (monaural) mode.
• Compensation — Source gain compensation that normalizes input levels
from different sources; for example, setting the volume range of a VCR
equal to that of a CD player.
• Mute — Electronically attenuates signal.
• On/Off — Activates electronic relays that cut sound to a room.
Optional source and numeric keypads or any other Crestron network panel or
touchpanel may be added to the individual rooms to interface with the CNX-
BIPAD8. For more information regarding such devices, refer to the Downloads |
Product Manuals section of the Crestron website (www.crestron.com).
NOTE: Unit does not ship with default parameters for adjustable values (bass,
treble, or compensation). These values must be set in the program for the unit to
operate correctly.

Setup
Network Wiring
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Downloads | Product Manuals | Software and Wiring Diagrams section of the
Crestron website (www.crestron.com).
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the

Professional Audio Distribution Processor Crestron CNX-BIPAD8
8 •Professional Audio Distribution Processor: CNX-BIPAD8 Operations Guide - DOC. 8160A
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
R < L x PF
40,000 Where:
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table after this paragraph.

NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is
the +24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
NOTE: When daisy chaining network units, always twist the ends of the incoming
wire and outgoing wire that share a pin on the network connector. After twisting the
ends, tin the twisted connection with solder. Apply solder only to the ends of the
twisted wires. Avoid tinning too far up or the tinned end becomes brittle and breaks.
After tinning the twisted ends, insert the tinned connection into the network
connector and tighten the retaining screw. Repeat the procedure for the other three
network conductors.
Identity Code
Every equipment and user interface within the Cresnet system requires a unique
identity code (NET ID). These codes are two-digit hexadecimal numbers from 03 to
FE. The NET ID of the unit must match the NET ID specified in the SIMPL
Windows program. Refer to “Setting the Net ID in Device Settings” on page 16 for
details of the SIMPL Windows procedure. The NET ID of each CNX-BIPAD8 has
been factory set to 44. The NET IDs of multiple CNX-BIPAD8s in the same system
must be unique and changed from a personal computer (PC) via the Crestron
Viewport, which is available through VisionTools®Pro-e (VT Pro-e) or SIMPL
Windows, or as a standalone utility.
NOTE: For detailed information on establishing communication between the PC
and Control System, refer to “Communication Settings” on page 19. If
communication cannot be established, refer to the “Troubleshooting
Communications” section in the respective Operations Guide for the control system.
NOTE: VT Pro-e is a Windows compatible software package for creating Crestron
touchpanel screen designs.

Signal Distribution to More than Eight Rooms
Each CNX-BIPAD8 is capable of distributing audio to eight rooms, maximum. It is
possible to expand distribution to more rooms if additional CNX-BIPAD8s are
introduced to the system. Crestron recommends a maximum of four CNX-BIPAD8s
per system. Therefore, audio can be distributed to a maximum of 32 rooms.
NOTE: Connecting more than four CNX-BIPAD8s via loop-through may result in
diminished audio quality and signal degradation.
The sixteen sets of four RCA jacks connect independent audio sources to the
CNX-BIPAD8. Of each set, two of the connectors are used for left and right audio
channels; the other two are parallel stereo loop-throughs. The loop-through jacks can

Crestron CNX-BIPAD8 Professional Audio Distribution Processor

be used for daisy-chaining additional CNX-BIPAD8s, as shown in the following
figure.
Expanded Audio Distribution
Expanded Distribution of Local Audio Sources
Using the unbalanced (RCA) loop-through I/O connections between the
CNX-BIPAD8s, you can ensure that the head end source inputs on the first
CNX-BIPAD8 can be distributed to the rooms connected to the balanced audio
CAT5 I/Os on other CNX-BIPAD8s.
However, if you wish to distribute local room source audio from rooms connected to
the first CNX-BIPAD8 to rooms connected to a second CNX-BIPAD8, you need to
use the CNX-PBAR4 as shown in the diagram on the next page. The CNX-PBAR4
allows you to maintain the balanced CAT5 I/O connection to/from rooms 1-4 on the
first CNX-BIPAD8, then, via it’s internal balanced to unbalanced audio converter, to
loop through the return audio coming back from the rooms to the RCA unbalanced
inputs on the second CNX-BIPAD8. As shown in the diagram, the CNX-PBAR4
will enable Rooms 9-12 to listen to audio being routed from rooms 1-4.
