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 12 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! 6 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 connectors. 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 Audio interface products solve audio problems for thousands of people around the world. 3
