The hardware is physically identical to the staff-side \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-su1-3w-staff-loudspeaker-unit-with-dual-mute-switch\" rel=\"noopener\" target=\"_blank\"\u003eSTS-SU1-3W staff unit\u003c\/a\u003e: same cardioid microphone on a semi-rigid gooseneck with adjustable neck, same 5-watt speaker, same mild-steel freestanding base. The only difference is that the mute switch has been removed from the front of the unit, which is the right choice for the customer side, where you don't want a customer to be able to mute the staff microphone (or their own) during a transaction.\u003c\/p\u003e\n\u003cp\u003ePositioning the STS-SU1-NM on the customer side gives a bank teller window, pharmacy counter, ticket booth, or government service counter a two-way intercom where both sides have an identical speaker-and-microphone unit sitting on the counter in front of them. The customer sees the same hardware the staff member sees, which is reassuring at a service window where mystery hardware behind glass can make customers hesitate to speak clearly. The freestanding base means staff or facilities can slide the unit to the right position for a shorter or taller customer, or move it out of the way during cleaning, without unmounting hardware.\u003c\/p\u003e\n\u003cp\u003eThe cardioid directional microphone picks up the customer's voice from directly in front of the microphone head and rejects sound from the sides and rear, which matters at a busy service window where lobby noise, HVAC fan noise, and the next customer's conversation would otherwise bleed into the staff-side audio. The semi-rigid gooseneck lets the customer position the microphone close to their mouth for consistent pickup regardless of posture or height.\u003c\/p\u003e\n\u003cp\u003eThe 5-watt speaker runs at 4-ohm impedance with 85 dB SPL output at 1 watt at 1 meter, and a 150 Hz to 10,300 Hz frequency response tuned for clear speech reproduction at desk distance. That is the same speaker output specification the \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-a31h-window-intercom-amplifier\" rel=\"noopener\" target=\"_blank\"\u003eSTS-A31H\u003c\/a\u003e window intercom amplifier is tuned to drive, so the STS-SU1-NM pairs directly with the STS-A31H and the matching staff-side STS-SU1-3W without added crossover or matching hardware.\u003c\/p\u003e\n\u003cp\u003eThe STS-SU1-NM ships in Contacta's commercial-grade mild-steel construction with a choice of two powder-coated finishes: Gray (STS-SU1-NM-G) or Black (STS-SU1-NM-B). The unit stands 14.50 inches tall at the top of the gooseneck with a 3.80-inch-wide by 6.02-inch-deep base footprint on the customer counter.\u003c\/p\u003e\n\u003cp\u003eFor the staff side of the same installation, pair this unit with the \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-su1-3w-staff-loudspeaker-unit-with-dual-mute-switch\" rel=\"noopener\" target=\"_blank\"\u003eSTS-SU1-3W staff unit with dual mute switch\u003c\/a\u003e.
