Crestron C2N-IADS30X24 Intercom Audio Distribution System
Intercom Audio Distribution
System: C2N-IADS30X24
Introduction
Features and Functions
• 16 RCA inputs combine left and right channels to create eight
The C2N-IADS30X24 Intercom Audio Distribution Switcher (IADS) facilitates the
distribution and control of audio intercom signals for up to 22 touchpanels and door
stations using inexpensive CAT5E cable. The IADS integrates neatly with Crestron's
CNX-PAD8A and CNX-BIPAD8 audio distribution processors, enabling voice
paging from any microphone-equipped touchpanel to room loudspeakers throughout
the house or office, and allowing audio from central AV sources to be distributed to
any touchpanel.
The IADS is built around a fully programmable 30x24 audio crosspoint matrix,
providing extensive flexibility for the distribution of intercom and other monaural
audio signals. Interfaced through 22 bidirectional CAT5 audio ports, the matrix
provides complete freedom to route the microphone signal from any one touchpanel
or door station to the speakers in another, with real-time control to permit fluid
talk/listen (half-duplex) intercom functionality. Crestron offers several touchpanel
models equipped with built-in microphones and speakers designed for use with the
IADS. Door stations are easily implemented using the C2N-IIF Intercom Interface
(sold separately).
mono inputs.
• 22 CAT5 line inputs/outputs for door stations and TPS
touchpanels (remote audio in/out).
• 4 RCA outputs representing two mono channels by combining the
left and right channels of each audio input.
• 1 five-pin miniconnector for CNXTA telephone card interface for
dial-up paging and control.
• 1 four-pin miniconnector for Cresnet hookup.
• Built-in 30x24 audio crosspoint switch. Any mono input can be
routed to any mono output. Any output can be turned off,
providing a high-isolation off state.
• Touch-settable ID (TSID) ready.

Eight unbalanced inputs are also provided to accept signals from the unbalanced
room outputs or loop-thru connectors of a Crestron audio distribution processor, or
from any stereo sources. Stereo input signals are internally summed to mono. Any
input signal may be freely routed to any number of CAT5 outputs. In addition, there
are two unbalanced outputs provided for connection to room inputs on the audio
distribution processor, allowing microphone and other signals to be routed to any set
of room speakers, easily accommodating the most complex zone-paging scheme.
Additional configurations can be achieved by interfacing CAT5 audio ports on the
IADS directly to CAT5 audio ports on the CNX-BIPAD8 and many other Crestron
products.
A 5-pin connector, paralleled with the last CAT5 I/O port, permits interfacing to
Crestron's CEN-TIA Telephone Interface Module (sold separately), enabling dial-up
paging through the client's phone system, and distribution of door chimes and other
sounds through the room loudspeakers.
The IADS functions as a slave device to any 2-Series control system communicating
via the Cresnet
®
control network.
Applications
Although the IADS can function alone as an intercom audio distribution controller, it
is ideally suited to work in combination with the C2N-IVDS24X24 (IVDS) intercom
video distribution system along with other Crestron audio/visual components and
TPS touchpanels to provide a variety of A/V functions throughout the facility. (Refer
to the simplified system diagram on page 3 and the functional diagram on page 4 for
more details.)
Paging
Connect the audio outputs of the IADS to a Crestron CNX-PAD8A (PAD8A) or
CNX-BIPAD8 (BIPAD8) audio distribution system to add whole facility paging
through the audio distribution system.
Connect a Crestron CNXTA telephone card (requires a control system that accepts
expansion cards) to the IADS to allow dial-up paging to specific or to all zones
throughout the facility.
A/V Source Monitoring
Connect the output of a PAD8A or BIPAD8 to the IADS to listen to A/V sources
through your TPS touchpanels.
Security Camera Monitoring
Connect the IVDS output to the input of a CNX-PVID8X4 or CNX-PVID8X3
(PVID8) video distribution system to view security camera output through any
display device, such as a plasma display or a projector, connected to the PVID8
output.
Video Monitoring
Connect the PVID8 output to the IVDS to watch video sources on your touchpanels.
Access Monitoring
Connect door station security camera, mic/speakerphone, and doorbell inputs and/or
outputs to the IADS and IVDS to monitor and control access to the facility from any
of your TPS touchpanels.
