AIO-L
The 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

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.
