Customer Talk-Thru Window Intercom – Full Duplex Hands-Free Communication with Mute Function & 15″ Gooseneck Microphone
The ZDL-9905E Customer Talk-thru Window Intercom is a professional-grade solution for secure and clear communication across glass, acrylic, or security barriers. Designed for banks, ticket counters, pharmacies, government offices, and customer service windows, this system enables natural, hands-free conversations with true full-duplex technology, allowing both operator and customer to speak and listen simultaneously.
The master operator station is built from a combination of durable aluminum alloy and rugged plastic for long-lasting use. It includes a 3-watt built-in speaker, high-gain low-noise microphone, and an adjustable 15-inch gooseneck microphone for precise voice capture. A mute function for both master and customer sub-stations ensures privacy and control when needed.
Features Sub-station Speaker MUTE, Master Station Microphone MUTE for User Privacy – Plug-and-Play Setup – No installation required; sets up in minutes using 6-foot audio jack cable
The customer-side sub-station is compact, featuring a 2.5-inch hands-free speaker with integrated microphone, designed for clear communication while occupying minimal counter space.
Operators benefit from independent volume controls for both master and customer microphones and speakers, making it easy to adjust for quiet or noisy environments. The system is plug-and-play, requiring no installation—just connect the included 6-foot audio cable from the sub-station to the master station’s input. The master unit delivers both audio and power to the customer station, simplifying setup.
For added functionality, the master station includes an auxiliary voice recording output, allowing connection to external recorders for compliance, training, or security monitoring. Compact yet durable, this talk-thru system provides fast deployment and reliable performance for busy service points.
