System 10K Modular Audio Amplifier Series
SYS10K
The ATI System 10,000 is the ideal unit for multiple distributions when it comes to stereo or
mono amplifying, microphone amplifying, or headphone distribution. The SYS10K is perfect
for any ballpark, museum, or large venue such as the United Nations where many of our
SYS10K systems can be found. The rack mounts up to ten amplifier modules and two power
supplies. Each plug-in module is supplied with it’s own applicable connector assembly,
thereby allowing for ease of insertion and quick hot-swaps.
The system features headphone jacks on all modules to allow a quick signal check. The
flexible design let’s you mix basic and metered modules in the same enclosure to optimize
your system performance. All input, output, and power lines are fully by-passed. The double
ground plane PC board shields with an additional top formed shield covering on each module,
protecting low-level circuitry from direct pick-up. The distribution power regulation on each
amplifier module minimizes localized heat build-up in the power supplies. The durable rack
makes the SYS10K a well-rounded device that speaks for itself.
