2-CH PoE Dante
™
Transmitter
Introduction
The AtlasIED TSD-DAC2i is a PoE 2-CH analog pre-amplifier that converts analog audio signals into Dante™digital
audio. The AtlasIED TSD-DAC2i can be used for any Analog to Dante™digital audio endpoint but is ideally suited
to be used with the AtlasIED WTSD wall mixer series. Once converted into Dante™digital audio, the audio can
be transmitted over IP networks and routed in the Dante Controller™software. The AtlasIED TSD-DAC2i Dante™
transmitter I/O module features two analog balanced line inputs with a variable gain to operate from Line to
Mic level. An input clip indicator prevents unwanted input clipping. There are indicators for Power and Network
connection. AtlasIED TSD-DAC2i requires no external power supply, it is powered via a network PoE port or a PoE
power injector.

Matching Gain from an Analog Source In a Dante™Network
Understanding the gain structure is very important to avoid clipping the audio signal or amplifier output. There are
three potential ways to clip the signal chain.
1. Amplifier Input Clipping
This occurs when the applied input signal exceeds the maximum input level of the amplifier input stage.
2. Amplifier Output Clipping
Driving the amplifier to maximum output level.
3. Digital Clipping
This occurs when the 0dBFS levels are exceeded. This is very important to understand. Several examples are
provided to help understand digital to analog gain structure. Note: AtlasIED recommends to always place a limiter
set for 0dB in the signal path prior to the Network Output of the transmitting device.
Selecting the Router or Network Switch - IMPORTANT!
It is extremely important to understand that when selecting a router or switch for the Dante™network, not all routers
or switches are the same. The size of the Dante™network will influence which router or switch is needed to handle
network traffic. There are three things to look for at a minimum or system dropouts may occur. Refer to Audinate®for
products they recommend.
1. Gigabit speed.
2. If using a network switch, it must be a “managed switch” type.
3. If using a router with a built-in switch, it should have DD-WRT firmware or Open Source firmware.
Dante™Overview
Audinate®created Dante™, an uncompressed, multi-channel digital media networking technology, with near-zero
latency and synchronization. Hundreds of Dante™enabled products are available from many manufacturers, enabling
devices from multiple manufactures to be deployed in the same installation.
Dante™does away with heavy, expensive analog or multicore cabling, replacing it with low-cost, easily-available
CAT5e, CAT6, or fiber optic cable for a simple, lightweight, and economical solution. Dante™integrates media and
control for an entire system over a single, standard IP network.
Dante™systems can easily scale from a simple pairing of a console to a computer, to large capacity networks
running thousands of audio channels. The network can be expanded and reconfigured at any time with just a few
mouse clicks because Dante™uses logical routes instead of physical point-to-point connections.
Since the signal audio is transmitted digitally, common analog challenges like interference from other electrical
equipment, crosstalk between cables, or signal degradation over long cable runs is not a problem. Setting up Dante™
networks is easy, even the most complex networks can be set up and configured quickly and easily with Dante™,
making system integration simple.
Signal routing and system configuration with Dante™is fast, simple, and incredibly flexible. Dante Controller™is a
powerful software application that manages devices on the network. Setting up a Dante™network is typically just a
matter of plugging devices into an Ethernet switch and connecting a computer to the network. All Dante™devices
are automatically discovered and displayed in Dante Controller™, so a system can be up and running in seconds.
Visit www.audinate.com for details or to learn more on using Dante™. There are many Dante™guides available in the
industry. AtlasIED offers one in the BlueBridge®DSP section of atlasied.com.

Important Information About Dante™
1. Dante™Levels in Dante Controler™
Signal level cannot be added or reduced within Dante Controller™. It is strictly a signal router.
2. What Does 0dBFS Mean
dBFS is a unit of measurement for amplitude levels in digital systems. When referenced to a number such as 0dBFS
or 20dBFS it is important to know that these are the maximum peak levels before clipping in the digital domain. It is
very important to know the source and receiver dBFS specification in order to set up the gain structure when signals
are being converted from the digital to analog domain or vise-versa.
3. Industry Standard
At the time of this writing, there is no industry standard between companies for scaling 0dBFS gain levels in
equipment. In a digital studio this is usually not an issue because most of the same brand is used or a limited number
of products are interfaced. However, with live sound or commercial audio there can be multiple brands used in one
project. Dante™can be great for connectivity between devices but be aware of gain structure matching.
4. Interfacing Data with Different Manufactures Equipment
To help understand scaling here are some examples:
• Source device 0dBFS = 20dBu, transmits to a receiver with a 0dBFS = 20dBu reference, the output is 0dBu.
This scenario is ideal when using an amplifier that has a 0dBu (775mV) input sensitivity.
• Source device 0dBFS = 20dBu, transmits to a receiver with a 0dBFS = 10dBu reference, the output is -10dBu.
To get full output of an amplifier that has a 0dBu (775mV) input sensitivity, increase the network output levels by
10dBu to get 0dBu into the amplifier’s input.
• Source device 0dBFS = 10dBu, transmits to a receiver with a 0dBFS = 20dBu reference, the output is +10dBu.
This combination will give too much signal into an amplifier that has a 0dBu (775mV) input sensitivity. Reduce the
signal from the DSP Network output.
• Source device 0dBFS = 10dBu, transmits to a receiver with a 0dBFS = 10dBu reference, the output is 0dBu.
5. Understanding Digital Noise vs Headroom
If headroom before clipping is a concern, the higher the ratio between 0dBFS and output level, the less likely
clipping will be an issue. If the application is paging and background music then a lower number is ok because
the headroom is not as critical. In live sound reinforcement applications such as a church band or a concert, more
headroom and gain is needed for dynamics. The issue with higher gain in a product is the higher the gain the higher
the noise output. To combat high gain output noise, use a Dante™Transmitter product with good signal to noise ratio
specification, such as 100dB or better. For instance, AtlasIED BlueBridge®DSP has a signal to noise ratio of 110dB.
The noise is very low before it is amplified, assuring low noise out of the amplifier. Look at the input and output 0dBFS
reference points and the noise floor specification. If they are not listed call the manufacturer.
