ARX Signal Processing: Applications Innovation The Dual program source
inputs allow you to put, for example, program material
into Channel A, and Pink Noise or a sine wave into
Channel B. Select either Input A or B and just
toggle between the two. 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. Status LEDs show which output is
currently active. Four different SUBs can also be selected
and compared with each powered loudspeaker. All Inputs and Outputs are
electronically balanced on Tip-Ring-Sleeve jack connectors,
and Loop outputs allow the Input signals to be looped to
additional i-Switch SUB units, for larger
testing arrays to be set up. Superb
Audio Quality The unique ARX
i-Switch SUB 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. i-Switch SUB

The new
i-Switch SUB 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 and a
choice of 4 Subs, making it ideal for batch testing or
demonstrating.
A
front panel MUTE ALL switch
and associated flashing LED allows you to mute everything
when you need to answer questions or discuss comparisons and
results without losing your level settings. The time
constants for Muting allow the signal to Mute over a 0.5 sec
window, and un-Mute over a 1.5 sec period. This helps
provide accurate level restoration without sudden ON/OFF
level changes or damaging transients.
The
iSwitch’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, B and Sub 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.
Audio is all we do...and we do it well.
