The 425-900 UHF In Ear Monitoring System sets new standards in terms of unmatched audio clarity, robust RF performance coupled with advanced configuration features to meet the most demanding professional applications.

Complementing it’s 20 channel capability, the 425-900 base station offers two line inputs, each with independent level control and bargraph indicators, enabling mono or stereo operation. Key focus has been placed on ease of programming with provision for settings to be synchronised between the base station and beltpack wirelessly via the infra red link.

Seamless integration with all Trilogy Intercom systems is effected using standard balanced 4 -wire connections together with the comprehensive IFB utility incorporated within the Trilogy configuration software.

The beltpack is intended for use with the Trilogy 420-26-02 flexible eartube, however the standard 3.5mm jack allows simple connection to most popular earpieces.
