Dual-Way Window Intercom System

The LiwCho LC-1908 is a two-way intercom designed for teller windows in banks, hospitals, offices and other business settings. It comprises a host unit, an extension unit and an external power supply. The system targets staff who need hands-free voice communication through a glass barrier without relying on wireless signals.

Wired 3.5 mm audio connection

Communication runs over a 4-core shielded audio cable that links the host to the extension via 3.5 mm jacks. The cable provides interference resistance and avoids the latency or drop-outs associated with wireless links. Operation requires a mains outlet for the external power adapter; the units contain no internal battery and cannot function during a power outage.

Replaces shout-through or basic window speakers

The LC-1908 upgrades from passive speaker grilles or simple one-way paging by adding automatic voice-activated duplex talkback and independent volume knobs for each side. The jump is worth it when clear, natural conversation is needed at a fixed counter and a permanent wired installation is acceptable. It does not suit mobile or multi-zone deployments.

Questions about this item

Which version of the LC-1908 intercom system should I choose?

The LC-1908 is offered as a single model that includes one host unit, one extension unit, a power adapter and mounting accessories — there are no alternative capacities or versions to select from.

What does the 3.5 mm jack connection mean once the system is installed at a teller window?

The 3.5 mm jack links the host and extension with a shielded four-core cable, providing automatic two-way voice communication without manual switching once both units are powered.

How does the 3.5 mm jack interface limit the system in practice?

The jack restricts the link to a wired audio cable between host and extension, so the units must stay within cable reach and cannot operate wirelessly or over a network.
