The Contacta STS-SU1-3W is the staff-side loudspeaker and microphone unit that Contacta ships in nearly every window intercom kit in its catalog, and it is available as a standalone unit for installers building custom systems or replacing a failed staff unit in an existing Contacta installation. This freestanding desktop unit combines a 5-watt staff speaker, a cardioid directional microphone on a semi-rigid stem with an adjustable neck, and a three-position dual mute switch that gives staff on-the-fly control over which microphones are open at any moment.
The dual mute switch is the STS-SU1-3W's main differentiator over a basic speaker-and-microphone unit. The switch has three positions: mute the staff microphone only (customer can still speak to staff, but staff conversation stays private on the staff side), mute both the staff and customer microphones (full privacy on both sides for a side conversation or a manager huddle), or both microphones open (normal two-way conversation). That gives the operator a quick way to pull a manager over for a question, discuss something privately with a coworker, or let the customer finish a phone call without the counter hardware broadcasting the audio back and forth.
The cardioid directional microphone picks up the operator's voice from directly in front of the microphone head and rejects sound from the sides and rear, which matters at a busy teller window or ticket counter where ambient noise from the lobby or the next operator over would otherwise bleed into the customer-side audio. The semi-rigid stem with adjustable neck lets the operator position the microphone head at the right height and angle for their seated or standing posture, so the microphone sits consistently close to the mouth for clear pickup across staff shift changes.
The 5-watt staff 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 STS-A31H window intercom amplifier is tuned to drive, so the STS-SU1-3W pairs directly with the STS-A31H without added crossover or matching hardware.
The STS-SU1-3W is the staff unit used in the STS-K001 bridge bar kit, the STS-K002 surface-mount kit, the STS-K003 flush-mount kit, the STS-K058 glass-mount curved microphone kit, and the STS-K020-S23 overhead speaker kit, among others. If you are running any of those kits and the staff unit has failed, this is the correct replacement. For a complete installation, you will also need a customer-side speaker and microphone, the STS-A31H amplifier, and the PS-55 power supply.
The STS-SU1-3W ships in Contacta's commercial-grade mild-steel construction, with a choice of two powder-coated finishes: Grey Leatherette (STS-SU1-3W-G) or Black Textured Powder Coated (STS-SU1-3W-B), plus one Stainless Steel Finish (STS-SU1-3W-SS). The base measures 2.76 inches tall, and the fully extended microphone stem reaches 14.50 inches, with a 3.80-inch-wide by 6.02-inch-deep footprint on the operator desk.
If you're not sure whether the STS-SU1-3W is the right replacement for your installation, please call us at 800-207-2259.
