Overview

The Angekis ASP-C-04 is a ceiling microphone kit built around a digital audio processor, with two suspended spherical microphones that pick up speech within a radius of up to 10 m. It applies adaptive echo cancellation, adaptive noise suppression and smart mixing, samples audio at 24-bit/48 kHz, and connects to a computer by USB Type-B. It suits boardrooms, lecture theatres and training rooms in Doha and beyond where remote participants need clear speech. Request a quote for a layout matched to your room.

What the ASP-C-04 ceiling mic system does

The Angekis ASP-C-04 pairs two suspended spherical microphones with a digital audio processor. Speech picked up in the room is converted, processed and sent over USB to the conferencing computer, so remote callers hear the people in the room rather than the echo or background hum that often spoils ceiling-based setups. The processor runs at 24-bit/48 kHz sampling with 24-bit A/D and D/A conversion, which gives a wide and clean signal path.

Processing and microphone facts that matter

Several features work together. Adaptive echo cancellation reduces the loudspeaker sound that would otherwise loop back to the far end, adaptive noise suppression lowers constant background sound, and adaptive speech gain adjustment keeps voices at a steady level as people move around the table. Smart mixing and intelligent remixing manage how the two microphone channels are blended.

Cardioid pickup pattern on each spherical microphone, with a maximum pickup radius of 10 m.
Microphone frequency response of 50 Hz to 20 kHz and a signal-to-noise ratio of 75 dB.
Audio processor frequency response of 20 Hz to 20 kHz, with dynamic range above 105 dB.
Phantom power at 48 VDC supplied to the microphones.

Where it fits in Qatar

In a boardroom in West Bay or Lusail, where directors join calls with teams in Europe or Asia, a ceiling array keeps the table uncluttered and the conversation natural. A private school in Al Wakrah fitting out classrooms for hybrid lessons can use one kit per room so teachers are heard clearly at the back of the class. A training centre in Education City running remote lectures can keep speech clear for participants abroad, and the processor's USB link lets the computer handle the call.

Planning the installation

Ceiling microphones depend on room shape, ceiling height and seating positions, so plan the layout before anything is fixed. The power adapter accepts 100 to 240 V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains supply, and outputs DC 12 V 2 A. The manufacturer lists an operating temperature range of 20° to 70°, humidity of 20 to 90% without condensation and a noise level below 48 dB, so check the ceiling void against these conditions. Supported computer systems are Windows XP and newer, and Mac OSX.

Confirm ceiling access and microphone spacing with a free site survey.
Run the USB Type-B link to the conferencing PC or laptop.
Use the 3.5 mm monitoring jack for local listening checks during setup.
Plan the 7-way phoenix connections for any external wireless microphone or mixer.

Questions about Ceiling Mic QS ASP-C-04

What is the Angekis ASP-C-04 used for?

It is a ceiling microphone system for meeting rooms, boardrooms and classrooms where remote participants need clear speech. Two suspended spherical microphones capture voices across the room, and the digital audio processor cleans the signal before it reaches the conferencing computer over USB. It suits spaces where users do not want table-top devices taking up room.

How large a room can it cover?

Each suspended spherical microphone has a maximum pickup radius of 10 m, so the system suits rooms where seats fall within that range. Large lecture theatres or long boardroom tables need a site survey first, because the layout determines whether the two microphones give full coverage of every seat.

Does it work with Zoom and Skype for Business?

The manufacturer states compatibility with common conferencing platforms, including Skype for Business and Zoom. The unit connects to a computer by USB Type-B and is supported on Windows XP and newer and on Mac OSX. Send the platform and version you use with your quote request so the connection setup can be confirmed before delivery.

Is it suitable for a boardroom in West Bay or Lusail?

Yes, for boardrooms where executives join calls with teams abroad. Adaptive echo cancellation helps stop loudspeaker sound returning to the far end, while adaptive noise suppression keeps speech clear. Because the microphones are ceiling-mounted, the table stays free of devices, which suits formal meeting rooms.

How could a private school in Al Wakrah use it in new classrooms?

A school fitting out classrooms for hybrid lessons can install one kit per room, so teachers are heard clearly at the back of the class. Adaptive speech gain adjustment helps keep voice levels steady as a teacher moves between the board and students. A site survey first will confirm how many classrooms and which microphone positions are needed.

What are the power requirements in Qatar?

The power adapter accepts 100 to 240 V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains supply, and outputs DC 12 V 2 A. Phantom power for the microphones is 48 VDC. SmartRooms Qatar will confirm the correct plug arrangement for BS 1363 sockets when preparing your quotation.

What operating environment does it need?

The manufacturer lists an operating temperature range of 20° to 70°, humidity of 20 to 90% without condensation, and a noise level below 48 dB. Summer temperatures in Qatar can be high in ceiling voids, so check the space before installation and ask SmartRooms Qatar to confirm it meets these conditions.

What does the warranty cover?

The manufacturer provides a 3-year warranty on this model, and SmartRooms Qatar supplies it under that manufacturer warranty. Detailed warranty terms are not listed in the product data, so ask for the written warranty statement with your quotation before placing an order.

What equipment is needed alongside the system?

The system needs a computer or device with a USB Type-B port and a conferencing application. The 7-way phoenix interface supports linking external devices such as wireless microphones or mixers, and the 3.5 mm monitoring jack allows local listening during setup and checks.

Is the ASP-C-04 certified?

Yes, it is listed with CE and FCC certification, which helps with procurement files and technical reviews. Government buyers can order against a purchase order or LPO, and tenders can be submitted through Monaqasat.

How do I request a quote?

Send your room dimensions, seat count and conferencing platform. Quotations are usually issued within one working day. Payment can be made by bank transfer, cheque or purchase order, and the quotation will confirm the configuration suited to your room.
