1 - Overview
The CDT 100 four input Dante interface is the ideal interface for adding mic inputs to a Dante system.
The small form factor to the CDT 100 allows them to be mounted almost anywhere, pung them close to the microphone
sources and minimizing interference-prone analog wiring.
CDT 100 Features:
Easy to install with under table mounng.
Audio and control signals transported over Dante.
4 X mic/line inputs using 3-pin de-pluggable connectors for “Balanced” or “Unbalanced” connecvity.
Provides phantom power for each input also supports a +48V phantom power opon.
Powered by an external +12VDC (ordered separately).
Power can also be daisy chained
The CDT 100 has 4 X connecons to support the CH32 buon and other Clockaudio control devices:
 CRM 202S
 CS S Series
 S 80S
 SM 80S
 TS001
The CDT 100 connects directly to ARM-C port for the ARM motorized microphone.
The CDT 100 has two network connecons to allow Dante Daisy Chaining (DDC).
DDC further simplies system infrastructure wiring by allowing mulple CDT100’s to use a single CAT 5 home run connecon
to a network switch.
Compable with any Dante capable audio DSP.
The CDT 100 can be controlled and monitored with 3rd party control soware using direct UDP messages.

In order to congure an CDT100 both to set up its internal parameters and also setup audio roung, the PC will need to be able
to communicate with it over the network.
While all Dante devices will be discovered regardless of the IP address setup on the PC, communicaon can only occur if the PC
and the device have compable IP addresses.
By default, CDT100 is set to get a dynamic IP address. As with all Dante devices, if the CDT100 device does not nd a DHCP server
to retrieve an IP address from, it will give itself an automac private IP address (APIPA) instead.
An APIPA is always in the range 169.254.x.y.
To ensure communicaon, the PC can either be set to get a dynamic IP address, or be given a stac IP address in the range
169.254.x.y. The PC may require a restart for the changes to take aect.
Further informaon on IP setup for an audio system using Dante can be found in the FAQ’s on the Audinate website
(hps://www.audinate.com/resources/faqs).

There are two parts of the device that require soware to setup:
1. The audio roung.
2. The congurable features of the device itself.
The audio roung should be carried out using Audinate’s Dante Controller, available for Windows and Mac OS X from the Audinate
website www.audinate.com along with instrucons on how to use the soware and seng up routes on a Dante network.
Dante Controller is a free soware applicaon that enables you to route audio and congure devices on a Dante network.
With automac device discovery, one-click signal roung and user-editable device and channel labels.
See the overview link for more details on Dante audio networking.
4.1 - IP Address Setup
Important Notes:
 When using Dante controller, the CDT100 will be shown using a default device name of CDT100-###### where ‘######’ is the
last six characters of the devices MAC address.
 Failure to correctly congure IP addresses will not allow an CDT100 device to correctly authencate in the soware and while it
will show up in Dante Controller. The input and output channels won’t be visible and roung of audio to and from the CDT100
will not be possible.
Features:
 View all Dante-enabled audio devices and their channels on the network..
 View and edit device clock and network sengs
 Route audio between devices, and view the state of exisng audio routes

5 – Dante Daisy Chaining
Overview:
A unique feature of the CDT100 is its ability to allow daisy chaining of devices. This allows CDT100 units in close proximity to one
another to ulize a single home run of Ethernet cable back to the switch thus saving on installaon costs.
Daisy chaining simply requires the new device be connected to the spare Ethernet port of the last CDT100 device in the current
chain.
Not only can the Ethernet connecon be daisy chained, power can also be daisy chained too by connecng the daisy chain power
output on the last acve device to the daisy chain power input on the new device.
The number of devices that can be daisy chained is limited.
The maximum that can ever be daisy chained is 6 devices in a single chain.
Beyond that the number of switch hops may cause audio problems due to excessive latency and increased clock jier.
The other limitaon is the power supply, if power is also being daisy chained from device to device.
Standalone:
If power is supplied to the rst device via a standalone supply, the supplies maximum power output determines the number of
devices it can support (assume 4W @ 12V DC per device).
To daisy chain a device to another CDT100:
 Connect an Ethernet cable from the data only port of the CDT100 to one of the ports of the CDT 100 to be chained to supply
the network informaon.
 To chain the power, connect the “Link out” connector to the “Link in” connector on the CDT100 to be chained.
 A third unit could be chained by connecng it in the same way to the second unit and so on.
Network Conguraon Note:
If the CDT100 units are installed in a networked daisy-chain topology, it is highly recommended to only congure unicast ows
from each of the CDT100 devices' Dante transmiers.
The addion of mulcast ows along the daisy chain can overwhelm the switches in the chain with unnecessary mulcast audio
trac resulng in potenal latency and network clock synchronizaon issues, especially on the units installed at the end of the
daisy-chain network segment.
Addionally, if there are a signicant number of mulcast audio ows congured on the Dante network, it is recommended that
the core network switches that interface to the daisy-chained CDT100 network segments be congured with the appropriate
IGMP sengs to shield the CDT100 chain from unnecessary mul-cast audio trac.

6 – Mounng
Installaon of the CDT 100 is very straight forward.
It is recommended that the unit be secured to a at surface with a screw through each mounng ange.
Dimensions for mounng are show in the Figure 9 below.
Use a No. 6 screw of a type and size that is applicable to the surface to which the CDT100 will be aached.
All connecons to the CDT 100 should be made before the power is applied.
 Aach any audio sources that will be used to the inputs. The inputs are balanced so be sure to check what output type the
source to be connected uses in order to nd how to connect it correctly . (see Hardware Connecons secon).
When powering, using an oponal external supply:
 Aach either Dante I/F port to a spare port on the Dante network switch using a CAT 5 cable.
 Aach the power supply to the power input jack and then power up the external supply.
If all steps are performed correctly, the power light on the front should be lit. There may also be some acvity on the CDT 100
Dante I/F LED indicators.
With no Dante network, both LEDs will remain o.
If an acve connecon is made, both LEDs will come on and if there is network acvity, the yellow LED will ash.

7.1 – Crestron
Simple Windows Name: Clock_Audio_CDT100_Module
Summary:
This module provides control and feedback of the Clockaudio CDT100 via UDP. It also provides true feedback.
General Notes:
 Pulse the Inialize input before performing any other operaons.
 The module ulizes a “Heartbeat” to maintain communicaon with the CDT100. This heartbeat will begin once preliminary
inializaon is complete.
 Should a heartbeat response not be received, the module will aempt to send the heartbeat two more mes in succession.
 If neither of these responses are received, the module will consider communicaon with the CDT100 to be broken, it will clear
all exisng data and output signals, and will aempt to re-establish communicaon with the CDT100 every 10 seconds.
 Once communicaon has been re-established, the module will automacally re-inialize.
 The module will automacally subscribe for available unsolicited feedback with the CDT100 upon inializaon.
Crestron Hardware Required: 3 Series Compable only
Setup of Crestron Hardware:
 Connect Crestron 3-series processor via Ethernet port of same network that CDT100 is on.
 Congure IP address of both Crestron and CDT100. (Ensure subnet sengs match).
