Introduction
3.1.
Overview
With the ADX-32 you can transmit 4 ADAT Lightpipe connections (32 audio channels) over a single
Cat.5 network cable, up to 100 meters in distance.
The 64 channel version ADX-64 can transmit 8 ADAT Lightpipe connections (64 audio channels) over
two Cat.5 network cables – it consists basically of two ADX-32 in one case.
The system is designed to provide maximum flexibility: Transmit direction is selectable for each of
the four ADAT connections separately, giving you the option to transmit 32/0, 24/8, 16/16, 8/24, or
0/32 Tx/Rx channels. With ADX-64, you can select the direction for each of the eight ADATconnections, e.g. to build a 48/16 multicore system.
Multiple extenders can be daisy-chained together to transmit audio signals to multiple locations.
Thus, complex configurations (e.g. audio distribution to multiple rooms or additional monitoring
stations) are easy and cost-effective to set up.
Each ADAT connection follows the „transmit once, receive multiple scheme“.
All ADAT connections operate completely independent of each other. This means it is possible to
transmit different data formats, sample rates, resolutions and even ADAT and SPDIF signals together
over one Cat.5 cable.
3.2.
Benefits
 Much lower costs compared with MADI or analog transmissions (cabling!)
 Lossless real-time transmission, virtually no latency or delays (in the nanosecond range)
 Scalable: available in 32 or 64 channel versions,
the 32 channel version can be upgraded to 64 channels with an additional module
 Heavily reduced cabling, one thin Cat.5 replaces 32 analog cables
 Local loopback function: each ADAT input is forwarded to the output on the same device. This
gives you the ability to connect additional monitors, or use it as wordclock source.
 Compatible with all data formats using TOSLINK connector technology:
ADAT Lightpipe, SPDIF, AC-3, DTS etc.
 Quality product „Made in Switzerland“

Installation notes
CAUTION: Use the Cat.5 cable ONLY between ADAT Multicore Extenders!
NEVER connect ADAT-Multicore Extender with ethernet networking equipment
(PC, Switch, DSL modem whatsoever)!
ADAT Multicore Extenders and/or the networking equiment may be DAMAGED!

Use only a DC adaptor with the indicated voltage, power, polarity and matching connector.
On wrong polarity, an internal resetteable fuse is tripped. Disconnect the power supply and wait 10
minutes before connecting again.
The second module in the 64 channel version is internally supplied with power, therefore it is no need
for an additional DC adaptor.

ADX-64: There are two DIP switch banks on the rear panel. Each bank sets the function for the
corresponding 32 channel submodule.
7.1.
Input/output mode (DIP switches 1-4)
The transmission direction for the ADAT connections 1-4 are set with DIP switches 1-4:

Input: ADAT connection is configured as input. The received ADAT data is sent to the Cat5
cable.
The input signal is looped back to the corresponding output jack on the same
device ("local loopback"). This gives you the possibility to connect additional
monitoring, or to use the signal as wordclock source (see 9.2. Digital 24/8
multicore (sync over ADAT)).

Output: ADAT connection is configured as output. ADAT data will be received from the Cat5
cable and is forwarded to the optical output.
NOTE: For each ADAT connection, exactly one device on a bus must be set to "Input". All
others have to be set to "output" (only one signal source, but many signal sinks are allowed).
You can choose which of the devices acts as the sender ("Input") for each ADAT conection
independently.
7.2.
Termination (DIP switches 5-8)
To avoid signal reflections which degrade signal quality, each end of the Cat5 cable has to be
terminated with matching resistors. These are integrated into the ADAT Multicore Extenders and can
be switched on by means of DIP switches 5-8.

On ADAT Multicore Extenders which are placed at the and of a Cat5 bus (that is, all devices
having only one Cat5 connector "A" or "B" plugged in), termination must be switched on.

On ADAT Multicore Extenders in the middle of a bus (that is, all devices where both
connectors "A" and "B" are used at the same time), termination must be switched off.
NOTE: Switches 5,6,7,8 must all either be„ON“ or all „OFF“ stehen. Other combinations are not
8
allowed and cause malfunction.

8.1.
Wordclock synchronization
General
In digital audio systems it is required that all devices (mixers, converters, effects etc.) work with a
common clock (the so-called "wordclock"). This ensures that signal is processed on all channels in all
devices at the same time. Without a common clock, local clocks drift apart with time, which may
cause disturbances like clicks, pops and dropouts.
ADAT Multicore Extender does not require a wordclock signal,
but transmits the wordclock signal which is contained in the ADAT data stream.
8.2.
Wordclock synchronization over ADAT
The wordclock signal is generated by a master device (mostly the mixer) and is output along with the
audio data over the ADAT interface. Devices receiving the signal reconstruct the wordclock from the
data stream.
When using ADAT synchronzation, there is no need for additional sync cables.
Use the "Local Loopback" function (see 7.1. Input/output mode (DIP switches 1-4)) to have
additional ADAT sources for synchronization purposes. Look at the example in 9.2. Digital
24/8 multicore (sync over ADAT).
8.3.
Wordclock synchronization over separate coax cable
This configuration is often used in larger installations where simple ADAT sync is not sufficient.
The sync signal generated by the master (mostly the mixer) is distributed over a separate cable to all
devices involved. Commonly used is 75 ohms coaxial cable with BNC plugs, with 75 ohms
termination resistors at each end.
If you want to use this kind of sync distribution, you have to lay an extra coaxial cable beside the Cat5
cables (see 9.3. Digital 48/16 multicore (sync over separate coax cable)).
