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.

NOTE: Outputs from the RCA and RJ-45 CAT5 connectors (ROOMS 1-8) are the

same signals. The RCA outputs first pass through preamplifier and tone/volume

control circuits; the balanced outputs from the CAT5 connectors are unprocessed.

The eight pairs of RCA jacks output pre-amplified (line-level) and volume/tone

processed audio to corresponding room power amplifiers. Each room output contains

left and right audio channels. (These are the same signals as the unprocessed outputs

from the CAT5 connectors.)

1 – 16 (Source Connectors)

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.

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

CNX-BIPAD8.
