Introduction
Thank you for choosing this
ARX
i-switch
. We hope you enjoy using this unique
product as much as we enjoyed creating it. As with all ARX equipment, it has
undergone extensive factory testing and ‘burn in’ before shipping. To ensure
continued trouble free use, please familiarise yourself with the contents of this manual
before using.
About the
i-switch
The
i-switch
is a unique precision piece of test equipment, being able to individually
send a choice of two program sources to 12 pairs of powered loudspeakers, making it
ideal for batch testing or demonstrating. For example, Channel A could have Pink
Noise or a sine wave, and Channel B program material. Interlocking switches prevent
more than one Input being selected at a time.
Interlocking switches also prevent more than one Output pair being selected at a time,
so that each Output pair can be stepped through by pressing the subsequent switch. A
status LED shows which output is currently active.
All Inputs and Outputs are electronically balanced on Tip-Ring-Sleeve jack connec-
tors.
Loop outputs allow the Input signals to be looped to additional
i-switch
units, for larger
testing arrays to be set up.
The
i-switch’s
ultra low noise figures come from extensive use of premium
components, plus care and attention to board design and layout. The result is superb,
transparent audio quality and
the headroom to accurately reproduce the most demand-
ing input signal.
A and B Input Gains are adjustable from Off through to +6 dB via level controls on the
front panel. LED status indicators show which Input is currently active.
The unique ARX
i-switch
provides a truly innovative solution to testing multiple
powered speaker systems.
Every day, ARX Audio interface products solve audio problems for thousands of
people around the world.
