INTRODUCTION
The Livemix AD-24 is the the bridge betwen your analog console and the Livemix system. The
AD-24 receives line level audio signals and converts them to the Livemix Data format. Livemix audio
data is sent from the AD-24 to the MIX-16/32 over a single shielded CAT5 or CAT6 network cable.
Accessible front panel controls make the Livemix AD-24 very simple to setup, while front panel LED
meters allow for easy monitoring of incoming audio signals.
Livemix AD-24 features include:
• 24 Balanced/Unbalanced Inputs
• ¼” TRS and DB-25 (D-SUB) Audio Connections
• Front Panel +4dBu/-10dBV Select Switches (1 switch per stereo pair)
• Front Panel 3-Color Input Metering
• High Quality Audio Conversion
• External 12VDC Power Supply

2. POWER SWITCH: This switch turns on the power to the AD-24.
3. ¼” TRS INPUTS: These connectors accept a balanced or unbalanced line-level signal from your
analog audio source. Up to 24 separate audio channels can be fed to the AD-24, all of which are
available to your Livemix personal monitor mixers.

Whenever possible, we recommend using a balanced connection to the AD-24; balanced
connections allow for longer cable runs and offer better
interference rejection.
4. DB-25 INPUTS: Each DB-25 connector carries eight
separate channels of balanced, +4dBu audio signals,
using a single multi-pin connector. Since each connector
carries eight channels of audio, connections can be made
more quickly (only three connections instead of 24). DB-25
connections can also be secured using screws available on
the connector.
NOTE:
The DB-25 connectors on the
Livemix AD-24 are passed
through to the ¼” TRS inputs.
This means that you can
connect the DB-25 from your
mixer, and still use the TRS
jacks to connect the mixer
feed to another source.
The DB-25 connectors follow the TASCAM format. See
Appendix for more information on this wiring scheme.

5. INPUT LIGHTS: These lights give you a visual indication of the incoming audio signal level. Use
the signal level lights as a guide, when adjusting the output volume of the signal sources that are
feeding the inputs of the AD-24.
The input lights can be one of three colors based on signal strength:
-20dB (Green): A green light indicates a healthy signal level, and is where you want to see your
signal strength most of the time.
-6dB (Yellow): The yellow color indicates that the signal is
almost too loud, and should only occur when a signal is at
an occasionally loud moment.
NOTE:
If you see a red light, it may
0dB (Red): The red color indicates that the signal is
“overloading” the input, and needs to be turned down at
the source. If you see red lights, the source signal needs to
also be an indication that you
have the +4/-10 switches in
the wrong position.
be turned down in volume, or the signal will be distorted as
it is sent to the other parts of the Livemix system.
6. +4DBU/-10DBV SWITCHES: These buttons allow you to congure each pair of inputs for
different types of incoming signals.
If using unbalanced -10dBV signals, set the button to the
OUT position. This setting will optimize the connectors for
the lower-level signals common in consumer equipment
such as a portable digital audio player, a consumer CD
player, etc.
NOTE:
The AD-24 allows you to
select between these two
operating levels, by channel
pairs. This means that you

may mix and match different
incoming signal sources, and
do not have to choose an
overall input level for all 24
channels.
7. LIVEMIX DATA OUT: This connector is the output of the
AD-24. It sends a digitized audio signal containing all 24
input channels to a MIX-16/32 over a single shielded CAT5 or CAT6 cable.
8. LIVEMIX DATA LIGHT: This light will illuminate green when the AD-24 has a valid connection
and is sending data to a MIX-16/32. If this light is red, it is an indication that the connection to
the MIX-16/32 is not functioning properly. A shielded CAT5 or CAT6 cable is required for proper
sync.

SETUP AND OPERATION
The AD-24 will most likely be installed in a rack near the
mixer, but this is not required. The MIX-16/32 will likely
be placed near the stage. A single shielded CAT5 or
CAT6 cable will connect the AD-24 to the MIX-16/32 and
transmit all the necessary audio data for creating personal
mixes.
NOTE:
The most common audio source
for feeding the AD-24 inputs will
be the direct outs on an analog
mixer.
1. Attach the external Power Supply to the AD-24
External Power Supply connector.
2. Connect the AD-24 to the analog signal source.
• Either balanced TRS or DB-25 connections are
acceptable.
• If necessary, the connections can be mixed, for
example, you may have channels 1-8 connected
via DB-25 and channels 9-16 on TRS connections.
• The TRS and DB-25 connections are in parallel. For
example, a signal input on channel 1 via DB-25 will
appear on TRS channel 1. In this way, the AD-24
can pass through an analog signal from one device
to another.
3. Adjust the front panel switches for the appropriate
signal levels.
4. Connect the Livemix Data Out port on the AD-24
to the Livemix Data In port on the MIX-16/32 with
shielded CAT6 cable.
If your mixer does not offer direct
outs, you can use the inserts. If
using inserts, a special cable must
be used. This cable will short the
Tip and Ring of the TRS cable for
proper operation. This cable is
part number CBL-DBINSERT-10
and is available from your Livemix
dealer.
NOTE:
Networking cable comes in
a variety of “avors”. For the
purposes of Livemix, either CAT5
or CAT6 cabling is appropriate,
but it does need to be shielded.
5. Turn on the power switch to the AD-24.

LIVEMIX SYSTEM EXAMPLES
A Livemix system requires either an analog (AD-24) or digital input (option card), the MIX-16/32
central mixer, and at least one CS-DUO personal mixer. Below are some examples of what a basic
system may look like.
ANALOG INPUT SYSTEM
1 x AD-24 Analog Input Rack Unit
1 x MIX-16 Central Mixer
4 x CS-DUO Dual Mix Personal Mixers
4 x MT-1 Dual Position Mounts
1 x CBL-CAT6-100 Shielded CAT6 Cable 100’ **
4 x CBL-CAT6-50 Shielded CAT6 Cable 50’
**Shielded cable between AD-24 and MIX-16 is required. CAT6 is not required, CAT5 is acceptable.
ANALOG OR DIGITAL?
Users receiving their audio from an analog source will use the AD-24. Using the TRS or DB-25 inputs,
audio from the source is made available to the Livemix system.
Users receiving their audio from a digital source will use the Option Card (LM-DANTE-EXP). This is
an option card that is installed in the MIX-16/32 and allows the Livemix system to receive audio from
a digital device or network.
DIGITAL INPUT SYSTEM
1 x MIX-16 Central Mixer
1 x LM-DANTE-EXP Dante option card
4 x CS-DUO Dual Mix Personal Mixers
4 x MT-1 Dual Position Mounts
1 x CBL-CAT6-100 Shielded CAT6 Cable 100’ **
4 x CBL-CAT6-50 Shielded CAT6 Cable 50’
CONTROL SURFACE
Livemix needs at least one connected personal mixer to make a mix. Each Livemix CS-DUO personal
mixer connects via CAT5/CAT6 cable to one of the ports of the MIX-16/32. Using various controls on
the unit, two users can each create their own custom mix, which is then output to headphones, in-ear
monitors or stage monitors, right from the CS-DUO unit.

TROUBLESHOOTING
MY AD-24 IS NOT TURNING ON, AND I DO NOT SEE THE POWER LIGHT ILLUMINATING.
Check to make sure that you have the AD-24’s external power supply connected to a working
power outlet.
I DO NOT SEE THE LIVEMIX DATA LIGHT ILLUMINATING, ON THE FRONT PANEL.
If the Livemix Data light is not illuminating, there is a problem with the power to the AD-24.
Check to make sure that the power supply is connected to the AD-24 and that all the cables are
secure. Also check to ensure that the power supply is plugged into an appropriate power source
and that the power cable from the source to the power supply transformer is securely attached.
THE SIGNAL LEVELS COMING IN TO THE AD-24 ARE WAY TOO LOUD/WAY TOO SOFT.
• Adjust the +4/10 level buttons on the front panel of the AD-24.
• If feeding the AD-24 from a consumer-level, -10dBV signal, set the level switches for -10
• If feeding the AD-24 a professional-level, +4dBu signal, set the level switches for +4
If the above are all correct, check the settings on your console or interface that is feeding the
AD-24. Some mixers provide the ability to adjust the output gain on direct outs, or in some cases
the direct outs are “post-fader”, meaning that adjusting the fader also changes your direct outs.
Consult the manual for your particular mixer to best understand the signal path for each channel.
I HAVE SET THE +4/-10 SWITCHES TO THE CORRECT SETTING, BUT THE LEVELS ON SOME
INPUT CHANNELS ARE STILL A LITTLE TOO SOFT/LOUD. HOW CAN I FURTHER FINE TUNE
THE LEVELS COMING INTO THE AD-24?
The AD-24 does not offer individual input gain control for each channel; if you want to ne tune
the signals further, you will need to adjust the strength of the audio signal directly from its source.
In most cases the source will be an analog mixing console that is also being used to provide the
live sound mix in the venue.
In this case, you should be able to nd a setting for each mixer channel’s gain knob, that works
well both for the mixing console itself, as well as the signals being sent from the consoles direct
outputs, to the inputs of the AD-24.
EVERY TIME I SET UP OUR EQUIPMENT AT AN EVENT, IT TAKES A LONG TIME TO
CONNECT 24 SEPARATE ¼” CABLES, FROM THE DIRECT OUTPUTS OF THE MIXING
CONSOLE, TO THE 24 ¼” INPUTS OF THE AD-24. IS THERE AN EASIER WAY?
The AD-24 also offers three separate 25-channel DB-25 connectors on its rear panel, each
accepting 8 channels through a single multi-pin connector. By using cabling that terminates on
the AD-24 side using DB-25 connectors instead of ¼”, you can feed all 24 inputs using only three
connections, instead of 24 separate ones.
LIVEMIX AD-24

HOW DO I ADJUST THE GAIN ON THE AD-24? WE ARE USING ANALOG OUTPUTS ON A
DIGITAL CONSOLE AND WE JUST CAN’T SEEM TO GET IT LOUD ENOUGH.
The AD-24 does not have any gain controls, but typically, this is caused at the console level. Each
console is different, but generally, when a digital signal is routed to an analog output, there is
some form of gain control. Consult the users manual for your console to nd out how to adjust
this.
