Retevis RT-9908 Window Speaker System (4 Pack)

Four-Pack Window Intercom System

The Retevis RT-9908 Window Speaker System ships as a four-pack of two-way intercom units designed for service counters in banks, schools, clinics and retail stores. Each unit enables automatic voice transmission without pressing a button, so staff and visitors can speak naturally through a partition. A high-sensitivity microphone with anti-interference filtering keeps dialogue clear even in noisy surroundings.

Counter-Top Installation With External Recording

Each host unit includes a recording output jack that connects to external recording equipment and automatically captures the active voice signal during a call. The flexible microphone neck adjusts to suit the installer’s height and the mounting position, while its 187 cm cable allows convenient routing across a window or desk. Two volume control buttons on the host provide independent level adjustment for the local environment.

Upgrade From Single-Unit Press-To-Talk Sets

This system replaces single-channel press-to-talk intercoms that require manual switching and lack recording integration. The jump is worth it when a site runs multiple service windows simultaneously and needs hands-free, full-duplex conversation with a permanent audio log. Buyers who only need a single portable handset or wireless operation should consider a different form factor.
