The bridge-bar form spans 24.4 inches across the top of a security window or counter screen on a horizontal bar in mild steel, with a 5-watt speaker pod on each end for wide audio distribution to the customer and a cardioid directional microphone mounted on a short vertical stem at the center of the bar. The whole unit mounts above the counter window at eye level for the customer, giving staff and customers clear two-way communication through the glass without a separate mic and speaker.\u003c\/p\u003e\n\u003cp\u003eThe bridge-bar form matters at wider counter windows where a single-speaker unit cannot deliver clear audio across the full customer-facing area. The two speaker pods, spaced 19.68 inches apart on the bar, give the customer clear audio whether they are standing directly in front of the window, slightly to the left waiting for a receipt, or on the right side signing a form. For bank teller windows, post office counters, airport ticket counters, information centers, and government service counters where customers naturally shift position during a transaction, the dual-speaker spread is more forgiving of position than a single-point speaker. The cardioid microphone sits above the center of the bar on a short vertical stem, pointed down and forward to pick up the customer's voice directly in front of the window while rejecting ambient lobby noise from the sides and rear.\u003c\/p\u003e\n\u003cp\u003eThe combined speaker-and-microphone design in one bar simplifies installation compared to running a separate stem microphone and a separate overhead speaker. One unit, one cable run back to the amplifier, one mounting operation. For retrofits where a counter window is being updated with an intercom and the installer wants to minimize wall-penetration points, the single-unit bridge bar is the fastest install path.\u003c\/p\u003e\n\u003cp\u003eTechnical specs: cardioid directional microphone with 70 Hz to 14 kHz frequency response, -67 ±3 dB sensitivity at 1 kHz, 1.6 kΩ impedance. 5-watt RMS speaker at 4-ohm impedance with 85 dB SPL at 1 watt \/ 1 meter and 150 Hz to 11 kHz frequency response.
