AIO-L

LThe Line-level Test Module (AIO-L) is designed for making basic acoustic or electrical measurements of a device under test (DUT). AIO-L 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 balanced line-level outputs

Key Applications

  • Mobile devices
  • Communications systems

Performance

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.
