Power Requirements
None. The ISO-Later and ISO-
Splitter are passive iso-transformer
coupled devices,
ie.
they don't need
power to run.
Please note that it is advisable to
power down the system before con-
necting the ISO-Later or the ISO-
Splitter, to avoid the risk of sending
large electrical and signal noises
through the system when discon-
necting and re-connecting
As well as the
ISO-Later
and the
ISO-Splitter
, ARX manufacture
other products in the unique
Audibox range:
The
ISO Balancer
for balancing
unbalanced signals, and also the
ISO
De-Balancer
, which will de-bal-
ance a signal when required to con-
nect to an unbalanced input.
The
AV-DI
is a stereo AudioVisual
Active Direct box, with dual RCA
and stereo mini jack inputs plus dual
XLR outputs. Ideal for interfacing
consumer audio (especially compu-
ter sound cards) with professional
systems.
The
Ear Driver
is a Headphone
Amplifier with 2 pairs of Stereo in-
puts each feeding two channels of
headphone level outputs. It has in-
dividual Level controls plus a 12 -
15VDC power connector. A com-
pact, flexible unit
The
Pro-D
I is an ultra compact Ac-
tive Direct box, with normal High
Impedance input as well as a sepa-
rate speaker level input for connec-
tion to instrument amplifiers.
Other features include –20dB Pad
and Audio Ground Lift switches,
plus Phantom or DC power op-
tions.
Available in Single Channel or Dou-
ble Header format

Using your Audibox
The ISO-Later is designed to be in-
serted into the audio signal chain to
fully isolate the audio signal and to
float the audio Ground. It is a self
contained, stand alone single or dual
channel unit with a balanced female
3 pin XLR input and a balanced male
3 pin XLR output. It will have appli-
cations in Live Sound, Studio or
Broadcast use.
The ISO-Splitter is designed to be
inserted into the audio signal chain
to fully isolate the audio signal, float
the audio Ground and split the out-
put. It is a self contained, stand alone
single or dual channel unit with a bal-
anced female 3 pin XLR input and
two balanced male 3 pin XLR out-
put. It will have applications in Live
Sound, Studio or Broadcast use.
About Ground/Earth
Loops
A short primer
Ground loops are caused or occur
when the ground connection in the
electrical mains power system is
duplicated by connections of
different impedance or resistance.
This difference causes an induced
potential difference or voltage to
either be produced or flow
between the various pieces of
equipment connected.
This phenomenon brings about the
effect we perceive as a HUM.
Transformer Isolation
By inserting a high quality audio
transformer (such as those used in
the ARX Audibox range) into the
signal chain we are able to break the
Pin 1/ Sleeve Audio Ground / Earth
connection, eliminating any Earth
loop induced hums.
For safety and noise reasons you
should ensure that both sides of the
signal chain are properly Grounded/
Earthed
