The Contacta STS-K058 is an indoor window intercom system built around a two-part customer-side setup: a discreet, surface-mounted speaker and a distinctive glass-mounted microphone that uses curved tubing to route the pickup element above the counter. Instead of combining the speaker and microphone into one all-in-one puck or bar, the K058 separates them so each component can be positioned independently for the best acoustic result. The speaker sits low on the counter near the customer's ear; the microphone extends above counter level on a curved boom that arcs cleanly across the glass, keeping the pickup close to the customer's mouth without obstructing sightlines or taking up counter space.
The complete kit includes a Contacta STS-M14-BENT customer glass-mounted microphone with curved tubing, an STS-S60 customer surface-mounted speaker, an STS-SU1-3W staff unit combining a cardioid microphone with dual-mute controls and a 5W speaker for the operator, an STS-A31H window intercom amplifier, an IL-AE99 under-counter hearing loop aerial (molded on site to the required size by your installer), and a PS-55 power supply.
Behind the scenes, the STS-S60 customer speaker runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt / 1 meter across a 150 Hz to 10,300 Hz speech-tuned range. The STS-M14-BENT customer microphone is a cardioid aluminum electret with a wider 70 Hz to 10,300 Hz frequency response tuned to capture the customer's voice at close range from the curved boom position. The staff-side STS-SU1-3W matches the customer speaker's frequency response and delivers 5W output. The STS-A31H amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The system is CE, RoHS, and WEEE compliant, and the hearing loop is certified to BS EN 60118-4 when installed correctly.
FAQS:
Q: What is the curved-tubing microphone and why choose it?
A: The STS-M14-BENT is a cardioid microphone element mounted on a curved aluminum tubing arm that routes the pickup up and over from a base on the customer side. Instead of a straight vertical stem or a low-profile puck, the bent tubing lets the microphone extend across the counter and stay close to the customer's mouth at a natural speaking height. The result is a cleaner acoustic pickup than a fixed low-position microphone would give, without needing a tall stem sitting straight up on the counter.
Q: How is this different from the STS-K035 half-bridge bar kit?
A: The K035 combines the customer speaker and microphone into a single half-bridge bar unit at the counter. The K058 separates them: a discrete surface-mounted speaker (STS-S60) sits at counter level near the customer's ear, and a curved-tubing microphone (STS-M14-BENT) mounts to the glass with the pickup element arcing across on a bent boom. Choose the K058 when you want to position each component independently for the best acoustic placement, or when the counter geometry doesn't support the half-bridge bar's fixed footprint.
Q: How is this different from the STS-K020-S23 glass-mount kit?
A: The K020-S23 uses an overhead-mounted STS-S23 speaker above the glass plus an STS-C100 stem microphone at the counter, and requires a pre-cut communication hole in the glass for the customer microphone unit. The K058 uses a lower-profile surface-mount speaker (STS-S60) and the curved-tubing glass-mount microphone (STS-M14-BENT). Choose the K058 for a lower visual profile and a curved-tubing microphone aesthetic; choose the K020-S23 when the glass already has a communication hole, and you want the higher overhead speaker projection.
Q: How does the hearing loop work?
A: The included IL-AE99 aerial is a copper-wire loop with PVC casing that mounts under the counter. The installer molds it to the required size on site, then connects it to the intercom amplifier. Once installed correctly, it meets BS EN 60118-4, the international standard for hearing loop performance, and broadcasts intercom audio directly to T-coil-equipped hearing aids in the immediate area.
Q: How many components come in the kit?
A: The complete set includes the STS-A31H amplifier, STS-SU1-3W staff speaker and microphone unit with dual mute, STS-S60 surface-mounted customer speaker, STS-M14-BENT glass-mounted customer microphone with curved tubing, IL-AE99 under-counter hearing loop aerial, and PS-55 power supply.
Q: Is installation complicated?
A: The electronics are plug-and-play, but the customer speaker mounts permanently on the counter, the microphone base mounts to the glass, the hearing loop aerial has to be routed and molded under the counter, and cabling has to be run between the staff and customer sides. Plan for a professional installer if you're not comfortable working with glass hardware, running low-voltage cable through service counters, or shaping copper-wire loop aerials.
