Using the i-switch
Applications
Individually testing or demonstrating multiple powered speakers or similar devices.
Setting Up
Setting up your i-switch is very straightforward and intuitive.
Firstly, connect the unit to AC power.
Please Note:
This is a dual voltage unit. It is essential that you check that the voltage on the
fuseholder cover below the AC connector on the rear of the chassis is set correctly
before connecting it to AC power. See Page 2 for more details on this.

1. Connect your choice of signal to the Balanced TRS jack input connectors of Channels A and
B. Keep the levels reduced until all wiring has been checked
2. Connect the outputs of the i-switch to the inputs of your powered speakers. Up to 10 pairs
can be connected.
3. Power up the speakers
4. Slowly bring up the i-switch input levels until the desired volume is reached
5. Step through the output switches and check that each speaker has been connected
properly. A status LED will light up to show which speaker is active.
Congratulations - You’re ready to go!

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
3
The i-switch is a unique precision piece of test equipment, being able to individually send a
choice of two program sources to 10 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 connectors, and
there is a Front panel 3.5mm Mini Jack connector that lets you easily access Input B with an
mp3 player.
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 demanding 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 Pro Audio interface products solve audio problems for thousands of people
around the world. We know we’re obsessive about audio quality, but we’re betting that you are
too!
