4.2. Available models
ADX-32B
Transmits f ur ADAT Lightpipe c nnecti ns and ne MIDI data stream ver a single Cat5 cable, up t a maximum
distance f 330ft (100m).
ADX-64B-PRO
Transmits eight ADAT Lightpipe c nnecti ns, ne MIDI data stream (tw pti nal) and a w rdcl ck signal ver
tw Cat5 cables. This device als supp rts extracti n f a w rdcl ck signal fr m any ADAT data stream.
The ADX-64B-PRO can als be used as dual-ADX-32B (it basically inc rp rates tw ADX-32B devices in ne case,
plus w rdcl ck). If y u daisy-chain fr m “Cat5 C nnecti n 1” t “Cat5 C nnecti n 2” with a sh rt Cat5 cable, y u
can duplicate all ADAT utputs, integrating m nit ring r rec rding equipment with ut additi nal splitters.
4.3. Input and Return channel configuration
The system is designed with maximum flexibility in mind: The directi n f data transmissi n can be selected
individually f r each ADAT c nnecti n. Thus, the ADX-32B can be perated in 32/0, 24/8, 16/16, 8/24 r 0/32
TX/RX channel c nfigurati n, and the ADX-64B-PRO can be c nfigured t 64/0, 56/8, 48/16 etc. t 0/64 f TX/RX
channels.
4.4. Daisy-chaining
F r audi distributi n t several places, up t 32 ADAT Multic re Extenders can be daisy-chained t gether. This
feature can be used f r c mplex setups, e.g. multi-r m audi distributi n r the c nnecti n f additi nal
m nit ring equipment. Each signal input can be l cated at an arbitrary ADX device in the chain, and is then
distributed t all ther ADX devices. This all ws very flexible setups f r rec rding and m nit ring.

5.1. Cat5 Connection 1
Carries ADAT connections 1-4 and MIDI1 data (on channel 1)
Jacks “A” and “B” are electrically paralleled.
The switch “Terminati n” must be set depending n the the number f cables plugged in:
1 cable = “ON”, 2 cables = “OFF”. If y u use nly tw devices (p int-t -p int c nnecti n), the terminati n
must always remain switched n.
Wr ng terminati n settings are, depending n the cable length, n t always immediately n ticeable and
the system appears t functi n pr perly. But reliability and immunity t n ise is significantly decreased,
because either signals reflecti ns ccur with missing terminati n r transmitters get verl aded by t
many terminati ns.
If y u're using the system in the same setup all time, y u may use sc tch tape t fix the push butt n ( r
rem ve the push butt n cap) in rder t prevent unwanted perati n.
NOTE: Redundant c nnecti ns (the c nnecti n f tw units with tw cables ver A and B at the same time) are
not supp rted! This w uld lead t signal l ps causing undefined current fl w.
5.2. Cat5 Connection 2 (ADX-64B-PRO only)
Carries ADAT connections 5-8 and wordcloc data (on channel 5). If Dual-MIDI-Option is installed, the second

If the P wer LED d es n t g n when a DC adapter is c nnected, check the p larity.
6.2. ADAT 1-4
The transmission direction (TX or RX) must be set using the DIP switches 1-4:
Input (DIP switch in l wer p siti n = OFF): The ADAT c nnecti n is c nfigured as input,
the received data is sent t the Cat5 cable.

The ADX itself d n t need a cl ck t perate. The w rdcl ck feature is pr vided f r the distributi n f the
w rdcl ck signal nly and is independent f the ADX perati n.
The w rdcl ck functi n uses Channel 5 f r transmissi n and can perate in tw different m des, selectable by
DIP switch 6:
Multi: ADAT transmissi n n channel 5 w rks as every ther ADAT channel. Additi nally, a w rdcl ck derived
fr m the ADAT data stream is utput n the WORDCLOCK jack. N te that in this m de, WORDCLOCK is
always an utput, regardless f the directi n setting – there's n need t feed a w rdcl ck signal int an ADX
unit. Set WC terminati n (DIP switch 5) t “OFF” when using this m de.
WC: In this m de, channel 5 is used exclusively f r w rdcl ck transmissi n. ADAT5 and MIDI2 are inactive.
N te that f r this m de, a w rdcl ck signal must be input at ne ADX device in the chain, and the directi n f
the w rdcl ck transmissi n must be set with DIP switch 1.
Use WC m de when c mpatibility with the f rmer ADX-64A-PRO m del's w rdcl ck m de is required,
r when y u d n't have an ADAT data stream where the w rdcl ck can be derived fr m.
Wordcloc termination
When using a c axial cable f r w rdcl ck distributi n, the cable must be terminated c rrectly.
The ADX devices have a built-in terminati n resist r which can be switched n by DIP switch 5:
In m st c nfigurati ns, w rdcl ck terminati n sh uld be “OFF”
Switch the terminati n “ON” nly when
- Ch5 is in WC m de and
- Ch5 set t “Input” and
- the ADX is the last device n the w rdcl ck cable.
General requirements for wordcloc termination
The w rdcl ck master device (the sender) sh uld be l cated at the end f the BNC cable chain. If there is any
terminati n switch r jumper, it must be “OFF”.
All devices in the middle f the cable (which are usually c nnected by “T”-shaped adapters must have their
w rdcl ck terminati n set t “OFF”.
The last device n the chain (where the cable ends) must have the w rdcl ck terminati n set t “ON”. This
can either be d ne by setting the appr priate switch r jumper n the device, r, if there is n such thing, by
installing a “T”-shaped BNC adapter with a 75 hms resist r attached. Different manufacturers handle
w rdcl ck terminati n differently, please refer t the manual f the respective device f r instructi ns.

7. DEVICE SYNCHRONIZATION
7.1. General concept
F r all signal s urces and sinks within a digital audi system, it is required t share a c mm n cl ck. This
ensures that data pr cessing n all channels and n all devices happens at exactly the same rate. Otherwise, the
individual cl cks w uld drift apart with time, causing the number f samples generated by ne device t differ
fr m the number f samples expected by an ther – a c mm n sympt m f r this are t dr p- uts, crackles and
dr pped samples.
T prevent this, ne device (usually the mix c ns le) is the cl ck master. All ther devices perate in slave m de,
f ll wing the master's cl ck signal when generating samples.
Tw ways exist t distribute the cl ck signal fr m the master t the slaves:
7.2. Synchronization over ADAT
Any ADAT signal can be used f r w rdcl ck synchr nizati n as it carries an embedded cl ck signal. The master
cl ck device utputs ADAT streams with the master cl ck timing embedded, and slaves can extract the
embedded w rdcl ck fr m the stream. Please refer t y ur equipment's manual h w t set the synchr nizati n
t ADAT. If this type f synchr nizati n is used, n additi nal cabling is required.
Use the "l cal l p-back” feature t break ut additi nal ADAT signal utputs which can be used as
w rdcl ck s urce. An example c nfigurati n using ADAT sync is sh wn under 10.1. Digital 24/8
multic re.
7.3. Synchronization over coaxial cable
F r larger installati ns, it is ften n t c nvenient t use ADAT f r synchr nizati n because f its limitati ns:
ADAT c nnecti ns cann t be split easily, and length restricti ns may prevent y u fr m reaching all devices. In
such cases, it is better t transmit the w rdcl ck signal ver a dedicated, separate c nnecti n. F r this purp se, a
c axial cable with BNC plugs is c mm nly used, c mbining l ng reach (>100m) with the p ssibility t distribute
the signal t several slave devices using “T”-shaped c nnect rs.
The ADX-64B-PRO's w rdcl ck feature eliminates the need f r running an extra c axial cable beside the
Cat5. Refer t 10.2. Digital 48/16 multic re with m nit ring and rec rding splits f r an example.
Y u d n't even need a BNC utput at y ur master device because the c axial w rdcl ck signal is
extracted fr m ADAT data. See 6.6. W rdcl ck (ADX-64B-PRO nly) f r details.

User's Manual
8. CABLE RECOMMENDATIONS
8.1. Cat5 cable
Cable Quality
Cat5 cabling is c mm nly used, cheap, with a huge selecti n n the market t ch se fr m. With the ADX
devices, any cable that meets Cat5 or higher (e.g. Cat5e, Cat6, Cat7) can be used. A higher “Cat” number cable
has n electrical advantage ver a basic Cat5 type, because the parameters where the higher graded ne
perf rms better are nly imp rtant f r much faster systems, like Ethernet applicati ns.
H wever, if mechanical r bustness is an imp rtant issue, it is rec mmended t use a ruggedized Cat5 cable with
Neutrik® EtherC n® c nnect rs. Ready-t -use cable drums are available fr m several vend rs; g d value f r
m ney, stage-pr ven Cat5 cable drums are made by Adam Hall, f r example.
Technology
Cat5 cable c nsists f f ur twisted pairs, each made up f tw single wires. One pair can carry ne ADAT stream
(8 channels), yielding a t tal transmissi n capacity f 32 channels. The transmissi n meth d used n the media
is called “differential pair signaling” r “balanced transmissi n”. This means that each signal is transmitted ver a
wire pair, where ne wire carries the inverted signal f the ther ne. In c ntrast t unbalanced (gr und-
referenced) systems, differential signaling pr vides very g d n ise immunity, because c upled n ise affects
b th wires the same way and can be cancelled ut at the receiver's side by subtracting ne wire's signal fr m the
ther. Additi nally, EMI is greatly reduced because the electric and magnetic fields surr unding the tw wires
cancel each ther ut.
The techn l gy used in the ADAT Multic re Extender (RS-485) has been used f r a l ng time, e.g. f r lighting
applicati ns (DMX) r harsh industrial envir nments (Pr fibus). The c mm nly used AES/EBU standard w rks in
a similar manner, but is, due t its relatively l w data rate, nly able t transmit tw audi channels ver ne pair.
State- f-the-art techn l gy is used in the ADAT Multic re Extenders t ensure reliable perati n at the higher
data rates required by the ADAT pr t c l.
8.2. Toslin (Lightpipe) cable
Cable Quality
T slink cables are generally n t critical if y u d n't exceed their length limit f 5m (16ft). Quality cables usually
pr vide a tighter fit (=better latching) in the jack than cheaper nes, and may perf rm better n l nger runs.
Technology
Plastic Optical Fiber (“POF“) cables are cheap and immune t electr magnetic interference, but are limited in
reach. Larger runs cause pr blems as the light pulses are attenuated t much, leading t data err rs which
usually result in dr p- uts r crackles. Furtherm re, POFs are als very sensitive t breaks and sharp bends
which may be a pr blem in harsh stage envir nments.

ADX-32B / ADX-64B-PRO
9. DIGITAL SIGNAL QUALITY
9.1. Latency
Latency has – in c ntrast t traditi nal anal g systems – always been a t pic in digital audi techn l gy. High
latency can lead t unwanted effects, such as phasing, hall, ech etc. and can seri usly affect audi perf rmance.
By design, ther digital snake s luti ns (e.g. Ethernet based systems) have a relatively high pr pagati n delay,
because audi data has t be sampled, buffered, c nverted, transmitted, buffered and then finally c nverted back
t the riginal f rmat. These delays can easily add up t several tens r hundreds f millisec nds which makes
them unusable f r many applicati ns, especially f r m nit ring purp ses.
One design g al f the ADX was t create a system with ne f the l west latencies n the market. This is
achieved by perf rming n c nversi n at all, and nly minimal buffering with cl ck alignment.
These measures allow an excellent overall latency of less then 1µs, which is not noticeable (sound waves
travel only 0.3mm during this delay)!
9.2. Jitter
In any digital audi transmissi n, the cl ck signal picks up a certain am unt f jitter (cl ck phase n ise). Jitter can
affect audi perf rmance (SNR) if a jittered cl ck is directly used f r D/A r A/D c nversi n, and can even lead t
dr p- uts r data err rs if the jitter values is s high that it is imp ssible t determine the c rrect value f a bit.
F r pr per perati n f ADAT c nnecti ns, jitter is als an imp rtant issue because the durati n f the “start f
frame” mark is used t calculate the sample p int f the subsequent bits in the data stream. In c ntrast t
biphase-mark enc ding used by SPDIF and AES/EBU, the ADAT signal uses NRZ enc ding which all ws the
d uble data rate, but makes it m re difficult t extract the pr per bit timing.
T c pe with jitter, each ADAT signal is fed t a PLL circuitry which cleans the jitter by rec vering pr per timing
characteristics bef re the signal is utput. The overall jitter of an ADAT signal transmitted over 100m (330ft)
Cat5 cable is only ±1.5ns typ. and is in the same range f the jitter usually intr duced by a standard sh rt fiber
ptic c nnecti n. This feature all ws seamless integrati n even with “picky” equipment (like the Pres nus
Digimax FS micr ph ne preamp, r Yamaha c ns les at 48kHz) which refuses pr per cl ck tracking when there
is a higher am unt f jitter in the signal.
