Echoport ILO 292-I vs. 292-II Models

Model	Description	Key Differences
292-I (ILO292 I)	The Echoport 292-I is a powerful, gold-standard solution designed to meet the highest clinical demands. It offers a comprehensive range of OAE tests, including TEOAE, DPOAE, SOAE, and DP Growth.	Unilateral TEOAE and DPOAE recordings only.
292-II (ILO292 II)	The Echoport 292-II dual probe builds on the capabilities of the 292-I, adding bilateral TEOAE and DPOAE recordings along with Contralateral Suppression for enhanced diagnostic performance.	Bilateral TEOAE and DPOAE recordings with contralateral suppression.

Note: Both models support the same core clinical OAE features and use the same V6 Clinical software, but 292-II is preferred for new users due to USB compatibility and updated hardware.
