AIO-S

S The Speaker Test Module (AIO-S) is designed for making advanced acoustic and impedance 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-S is a configuration option for the AIO Test System and requires the AIO chassis to operate.

Hardware Features

  • Two mic/line inputs
  • CCP/IEPE/ICP microphone power
  • TEDS reader for microphone data
  • Two 10 W class-D amplifier outputs
  • Internal 0.1 Ω impedance sense resistor
  • Additional inputs for voltage and current monitoring

Key Applications

  • Speaker measurements with impedance
  • Drivers

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

Two 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.

IMPEDANCE MEASUREMENT

Two additional inputs are used to measure load impedance via the remote voltage sense terminals and an internal 0.1 Ω sense resistor. These inputs appear as additional audio input channels.
