your Personal Monitor Mixing System™. This User Guide is designed to
familiarize you with your new product and to have you up and running in no
time.
Features
The A-16D is designed to distribute the A-Net Signal from either an A-16T
Transmitter or another A-16D Distributor. Each A-16D accepts one A-Net
input signal and provides for eight simultaneous A-Net outputs using Category
5 Cables. The A-16D A-Net Distributor enables parallel connection of A-Net
devices, simplifying stage and studio setups.
A-16D Features:
• Easily distribute A-Net from a central location or from other A-16D
Distributors
• One A-Net input, eight A-Net outputs
• Can insert DC power for A-Net devices into the Cat-5 cable
•  rack space footprint – mounts easily on standard rack shelf
• A-Net activity LED on the main input
• DC power indicator LEDs on each output
• Multiple A-16D Distributors can be used in a system
• Uses the same power supply as all A-16 system components
Your Personal Monitor Mixing System provides a host of professional features
designed to make the system flexible in a variety of music and audio situations.
A-16T Transmitter Features:
• Sixteen high-quality audio channels
• Adjustable input gain switches per channel pair
• Eight stereo channel Link switches
• Signal and Peak LEDs on each channel
• Sixteen -inch TRS jacks for audio Input connections

Connecting the A-16D
The A-16D is designed to create a network of A-Net devices. The A-Net signal
appearing at the input of the A-16D is distributed to each of the eight outputs on
the front panel. Devices are connected in parallel rather than in serial fashion.
Connections on the A-16D Front Panel
There are two sets of connectors on the front of the A-16D A-Net Distributor.
They are marked Input and Output.
The Input section accepts the A-Net signal coming from any A-Net device.
This is most likely going to be an A-16T Transmitter in average systems. You
can expand a Personal Monitor Mixing System by using as many A-16D A-Net
Distributors as required.
The Output section sends an exact copy of the input signal in parallel to each of
the eight outputs.
The connections on the A-16D front panel use standard Category 5 cables.
Front Panel LED Indicators
The front panel’s A-Net Input jack contains two LEDs. The yellow LED
indicates that the A-16D is powered on. The green LED blinks to indicate that a
valid A-Net signal is plugged into the Input jack.
The A-Net Output jacks also have an LED. This yellow LED indicates that a
particular channel has DC power available.
Connecting an A-16D to a System
In a simple system containing one A-16T Transmitter and a number of A-16
Personal Mixers, the A-16D A-Net Distributor sits between the A-16T and the
Personal Mixers.
A-Net Input
You can connect a Personal Monitor Mixing System in a variety of ways. In a
typical system, you will have your audio inputs connected to the Input jacks on
the rear of the A-16T. From the A-16T, the A-Net output on the front panel is

12
13
connected to the first Personal Mixer in the system. Each subsequent Personal
Mixer is connected by running a cable from the Mixer’s A-Net Output to the
A-Net Input on the next Personal Mixer. This type of connection is called a
daisy chain.
When using the A-16D A-Net Distributor, the daisy-chain linking of Personal
Mixers is optional. Up to eight Personal Mixers can be connected directly to the
A-Net signal outputs of the front of the A-16D.
To connect the A-16D:
• Connect the A-Net Output on the A-16T Transmitter to the A-Net
Input on the A-16D A-Net Distributor using a Category 5 cable.
A-Net Outputs
The eight A-Net Outputs on the A-16D A-Net Distributor all carry the same
signal. You can use any output to connect a Personal Mixer.
To connect a Personal Mixer:
• Connect a standard Category 5 cable from A-Net Output #1 on the
A-16D A-Net Distributor to the first Personal Mixer in your system.
• Plug the Personal Mixer’s DC power supply into an AC outlet.
At this point the Personal Mixer is connected to the A-Net signal chain. Any
audio appearing at the inputs of the A-16T should be available for mixing in the
Personal Mixer. Refer to the Personal Mixer User Guide for additional informa-
tion about using the mixing features of the A-16 personal Monitor Mixing
System.
Connect additional Personal Mixers using Category 5 cables from an available
Output on the A-16D A-Net Distributor to the A-Net Input on the Mixer.
Connections on the A-16D Rear Panel
There are two groups of DC power connectors on the rear of the A-16D A-Net
Distributor. The right side of the rear panel contains the power input for the
A-16D A-Net Distributor. The left side is marked Optional Remote DC Power.
These jacks are used to power any of the connected Personal Mixers connected
to the A-16D. Up to eight Personal Mixers can be powered in this manner.
Note: The power supplies used with the A-16 Personal Mixers and the A-16D
are interchangeable.

15
Powering a Personal Mixer Remotely
There are a number of advantages to adding power for a Personal Mixer at the
A-Net distribution point.
• No DC power supply is needed at the performer’s location
• Power supplies can be located at a central point offstage or in a
machine room of an audio facility.
• A one-cable solution for supplying A-Net and DC power to a
mixing station is possible.
To power a Personal Mixer:
• Connect the A-Net cables as described previously between system
components (from the A-16T to the A-16D).
• Connect the power supply for the Personal Mixer you want to
power remotely to the same numbered DC Power input on the rear
of the A-16D.
• On the front panel of the A-16D note that the yellow channel LED
will light for any channel output that has DC power connected.
• Connect a Category 5 cable from the powered A-Net output on the
A-16D to the A-Net input on the Personal Mixer.
• The Personal Mixer’s A-Net Active LED will light to indicate that a
valid A-Net signal is present.
• Continue connecting up to eight Personal Mixers in this manner.
Note: The DC power supply plugged into the rear panel of the A-16D can
power only one Personal Mixer. If you start a daisy chain from a Personal Mixer
powered from an A-16D, the additional Personal Mixer units will need a source
of DC power.
Each Personal Mixer that is powered remotely no longer needs a power supply
connected to its rear panel. If this happens accidently, however, note that you
cannot harm the system.
Expanding a System
Any number of A-Net devices can be used in a system. This includes A-16D
A-Net Distributors. To expand a system, additional A-16D Distributors can
be connected to any available A-Net Output, such as the outputs on Personal
Mixers or on other A-16D units.
To add another A-16D to a system, simply connect a standard Cat-5 cable from

14
15
the A-Net Output of the first device into the A-Net Input of the A-16D Distribu-
tor you want to use for system expansion.
At this point your audio network has grown to include an additional eight paral-
lel A-Net outputs. You have the option of adding DC power to any or all of the
A-Net Outputs on the expansion A-16D. Follow the instructions in the previous
section.
Rack Mounting
The A-16D A-Net Distributor can easily be mounted in a standard 19-inch
wide equipment rack. The A-16D occupies half of the rack width, allowing two
A-16D units to be placed side by side on a standard rack shelf. These shelves are
available as an accessory from many audio and studio suppliers.
There are two shelf-mounting holes in the bottom panel of the A-16D. The holes
accept a 6-32 size bolt. The depth of the hole in the A-16D bottom panel is 0.25
inches.
CAUTION!
Be careful when selecting mounting hardware for use with your accessory
shelf. Using bolts that are too long can damage the circuit boards of your
A-16D.
Use of improper mounting hardware will void your warranty.
