Contacta STS-S70 Speaker Pod for Window Intercom Systems

The Contacta STS-S70 Speaker Pod is a compact, high-quality speaker designed to be paired with Contacta window intercom systems where one-to-one communication happens across a counter or partition. The low-profile black ABS puck can sit free-standing on a counter or ledge, or be surface-mounted, giving installers flexibility for banks, ticket counters, information desks, and any indoor service window where clear speech has to reach the customer side without a full staff-unit housing.

Behind the perforated grille, the STS-S70 delivers 5 watts RMS into 4 ohms with 85 dB SPL output at 1 watt / 1 meter and a 150 Hz to 10,300 Hz speech-tuned frequency response. The precision-matched driver is the same speaker used inside Contacta's STS-SU1 staff unit, so audio character stays consistent whether you're extending an existing installation, adding a customer-side speaker to a kit, or replacing a damaged unit.

FAQS:

Q: What is the STS-S70 for and where does it typically go?
A: The STS-S70 is a speaker-only pod for the customer side of an indoor window intercom system. It's used at bank teller windows, post office counters, box office ticket windows, information desks, transit fare booths, and government service counters where the customer needs to clearly hear the staff member behind the glass or partition. Because it can either sit free on a counter or be surface mounted, it works in installations where a full flush-mount or larger housing isn't practical.

Q: How is the STS-S70 different from the STS-SU1 staff unit?
A: The STS-S70 is speaker-only. The STS-SU1 is a combined speaker and microphone housing designed for the staff (operator) side, with mute controls and a cardioid microphone for outbound speech. Use the STS-SU1 where the operator needs to talk and mute; use the STS-S70 where you only need audio output on the customer side.

Q: Free-standing or surface mount, how do I decide?
A: Free-standing works when the counter is deep enough to place the pod within a foot or two of the customer, and the installation doesn't need a permanent fix. Surface mounting is the right call for permanent installations where the pod needs to stay in one place, resist being knocked around, or route the cable neatly through the counter.

Q: What Contacta systems does the STS-S70 work with?
A: The STS-S70 pairs with any Contacta STS-series window intercom amplifier. It uses the same 4Ω speaker load as Contacta's other pods, so it drops into a standard STS-A31 / STS-A31H amplifier speaker output without additional matching.

Q: Is the STS-S70 rated for outdoor use?
A: No, the STS-S70 is an indoor-rated component. If you need a weather-resistant speaker for an outdoor service window, drive-through, or exposed application, use the IP54-rated STS-S80-IP overhead speaker instead. Call us at 800-207-2259 if you're not sure which speaker fits your install.

Q: What comes with it and what do I need to add?
A: The STS-S70 ships as a single speaker pod with a fly lead for connecting to your amplifier's speaker output. You'll need a compatible Contacta STS-series amplifier (STS-A31 or STS-A31H) and, on the staff side, a microphone or combined staff unit to complete a two-way conversation.
