AIO-A

AThe Acoustic Test Module (AIO-A) is designed for making basic acoustic measurements of a device under test (DUT)—typically a speaker or driver. Ideal for use with measurement microphones, ear simulators, artificial heads, speakers, actuators, and mouth simulators. AIO-A is a configuration option for the AIO Test System and requires the AIO chassis to operate.

Hardware Features

  • Four mic/line inputs
  • CCP/IEPE/ICP microphone power
  • TEDS reader for microphone data
  • Two 10 W class-D amplifier outputs

Key Applications

  • Speakers
  • Headphones & earbuds
  • Mobile devices
  • Microphones

The Echo AIO ™ is a modular audio test platform ideally suited for high-volume production-line testing and QA/QC verification. The AIO combines the functionality of multiple standalone devices into a single, integrated unit, making test stations both more reliable and less expensive.

MIC / LINE INPUTS

Four low-noise inputs accommodate a very
wide range of input voltages, from dynamic
microphones to line-level inputs. Features include adjustable gain, constant current power, and TEDS readers.
