Audio · SP-P and SP-C

A 4-metre room with a glass wall needs a ceiling array, not a louder speakerphone.

A USB speakerphone for a small office, a ceiling microphone array for the meeting room that echoes. Two products, picked by room size and wall material, sold inquiry-only from Austin to buyers across the United States.

SP-P puck: the USB speakerphone for a small office

The puck goes on the table in a room of two to six people, or in the bag of whoever takes calls from whatever room is free. It connects over USB-C to a laptop or over Bluetooth to a phone, and it picks up a full circle to about 2.5 m. Past that radius the far end starts hearing the person at the end of the table as a voice down a corridor.

We sell it for huddle rooms with soft furnishings, private offices and the desk of anyone who refuses a headset. We do not sell it for a ten-seat table. People try. They put the puck in the middle of a 4.5 m table and wonder why the seats at each end sound thin. The arithmetic is simple: 2.5 m of pickup from the centre covers a 5 m table only if nobody leans back.

Every unit gets current firmware and a 48-hour run on the platform you use before it ships. Teams buyers get it checked in Teams. Zoom buyers, in Zoom.

Reverb and glass

Most bad audio tickets are a room problem, not a faulty unit

Glass, plaster and a bare table return sound to the microphone a fraction of a second late. The far end hears that as mud.

1.5 mOur rule: mouth to microphone in a hard room

Keep every talker within about 1.5 m of a microphone in a hard room. In a soft room with carpet and panels you can stretch that to 2.5 m. That single number decides whether a puck works or a ceiling microphone array is the honest answer.

A glass wall is the worst surface in a meeting room. It reflects almost everything, and it is usually the long wall, so the reflection arrives right behind the talker's own voice. Turning up the speaker makes it worse because the microphone hears the room louder too.

The clap test

Stand in the middle of the room and clap once. If you hear a flutter or a ring afterwards, record it on your phone and send it with the photos. It tells us more than a floor plan.

Panels before hardware

Two 1.2 m fabric panels on the wall facing the glass often do more than a microphone upgrade. We will say so rather than sell you a tile you do not need.

The air vent

A ceiling array next to a supply vent picks up air noise. We steer lobes away and, where the grid allows, move the tile one square over.

SP-C

SP-C: a ceiling microphone array for the meeting room that echoes

The SP-C is a 600 mm tile that replaces one panel in a grid ceiling. It is powered and connected over a single PoE cable, and its pickup lobes can be steered: we aim them at the seats and away from the door, the vent and the coffee machine. Because it listens from above, the glass wall behind the talkers stops being the loudest thing in the room.

One tile covers a table of six to eight in a 4 × 5 m room. Long boardroom tables take two, tied together through a DSP, which is how the KIT-B boardroom kit is built. We mount it under ceilings of 2.4 to 3.2 m. Above 3.2 m we want a site visit before quoting, because pickup at that height depends on the room more than the spec sheet.

Cabling runs from the switch to the tile. Up to 90 m of Cat6 is inside the standard; most Austin offices we fit are under 30 m. If your network team needs the PoE class, it comes with the quote.

Mounting and install priced after photos

From photo to first call

How an audio order runs

Usually two to three weeks from photos to a working room, depending on stock.

  1. Day 1 to 2

    You send the room

    Length, width, ceiling height, seat count and a photo of each wall. A clap recording if you have one. We reply with a puck, a tile or a plain no, and a written quote.

  2. Week 1

    Bench burn-in

    Each unit runs 48 hours on the bench, signed into your platform where you give us a room account, with firmware set to the version your IT team approves.

  3. Week 2

    Install and lobe tuning

    In the Austin area we fit the tile, pull the cable and tune the lobes with someone on the far end of a real call. Outside Austin we ship pre-configured with a settings file and a phone session.

  4. 30 days

    Configuration support

    If something sounds wrong after a firmware push or a furniture move, call. The terms are on the warranty page.

Before you order

Questions buyers ask about room audio

Can I put two pucks in a long room instead of a ceiling array?

Up to about 5 m of table, yes, if the model supports daisy-chaining. Beyond that, the far end hears two rooms instead of one and the ceiling array is the cheaper fix over time.

Does the ceiling array need a drop ceiling?

A 600 mm grid ceiling is the simple case. Hard plaster ceilings take a surface-mount frame or a suspension kit, which we price after seeing photos.

My video bar already has microphones. Why add more?

A bar on the display wall hears the people nearest the screen best and the far end of the table worst. In rooms deeper than about 5 m, or any room with glass, a ceiling tile fixes the far seats. Read the video bar sizing table before deciding.

Who should not buy from this page?

Anyone after a single puck at the lowest online price. We configure and test every unit, and that time is in the band. If you only need the box, a retailer will be cheaper and we will say so.
