Overview

The Angekis Cleartalk ASP-04D-4S is a daisy-chained conference speakerphone: one controller with a digital active speaker and four wireless omnidirectional microphones. Each microphone picks up sound over 360 degrees within 3 metres, and the system provides full duplex audio with 256ms echo cancellation. Up to 10 hours of battery life suits meeting rooms in West Bay, Education City and government offices where a small team needs clear audio around one table.

One controller, four wireless microphones, one table

The Angekis Cleartalk ASP-04D-4S links a central controller and four wireless microphone units into a single conference audio system. The controller is a digital active speaker housed in a wooden enclosure with a black finish, and it connects to a computer over USB Type-B. Each microphone is omnidirectional with a cardioid response rated from 0 to 8,000 Hz, so people seated around a table can be picked up without passing a device from hand to hand.

Audio figures that matter in a meeting room

Coverage: 360-degree pickup with a 3-metre range for each microphone unit.
Full duplex: all four microphone units handle two-way audio at the same time, so both ends of a call can speak naturally.
Echo and noise control: 256ms echo cancellation and dynamic noise reduction processing.
Noise floor: the rated noise level is below 48 dB.

Together these figures mean the system is built for conversation rather than amplified announcements. Placing the controller near the centre of the table and each microphone within its 3-metre pickup zone gives the most even coverage for the group.

Power, wireless range and computer compatibility

Each microphone uses a built-in lithium battery rated at up to 10 hours, and the manufacturer lists the microphone units as wireless charger compatible, which reduces cables on the table. The 2.4G wireless connection reaches up to 20 metres. The controller has keys for microphone mute, loudspeaker mute, volume up and down, and a standby key. The system is listed for Windows 7, Windows 8, Windows 10 and Windows XP, and for Mac OS X 10.7 and later, and the manufacturer states it works with most computer audio software, including Skype, Zoom and TeamViewer. The controller also offers a 6.5mm audio output and a DC power interface. The manufacturer warranty is 3 years, with a 1-year guarantee on the battery.

Where it fits in Qatar

A boardroom in West Bay or Msheireb, where an executive team joins video calls with colleagues in other countries and needs every speaker heard without raised voices.
A seminar room at a university in Education City, where a lecturer and visiting speakers join a remote panel from one table.
A government ministry or authority meeting room, where Arabic and English speakers take turns on the same call and the controller sits at the centre of the table.

Qatar outdoor summer temperatures can exceed 45°C, but the controller's recommended operating range is 5°C to 44°C with 20 to 85% humidity, non-condensing. Install the system in an air-conditioned room, away from sun-facing windows, and keep it out of direct airflow from vents.

What to plan before you order

Measure the table and the distance from the centre to each seat before choosing the number of microphone sets, because each microphone's pickup range is 3 metres. Confirm the exact package contents with your quotation, since the source data lists active speakers as optional. If you are equipping several rooms, a single purchase order (LPO) can cover the whole project, and SmartRooms Qatar can arrange delivery to all 8 municipalities of Qatar with installation and a free site survey.

Request a quote from SmartRooms Qatar with your room sizes and the number of microphone units you need, and our team will confirm the configuration and availability for your site.

Questions about Cleartalk DC 4 Units ASP-04D-4S

What is the Angekis Cleartalk ASP-04D-4S used for?

It is a conference speakerphone system for a single table. A central controller with a digital active speaker connects four wireless microphone units, so a group can join a call from one meeting room. It suits boardrooms, seminar rooms and meeting rooms where several people speak on the same call and a single table layout is used.

How many microphones are included and how do they connect?

The system uses one controller and four wireless omnidirectional microphone units, daisy-chained together. The microphones connect over a 2.4G wireless link rated up to 20 metres. The controller connects to a computer by USB Type-B. Confirm the exact package contents on your quotation, as the source data lists active speakers as optional.

What pickup range does each microphone cover?

Each microphone unit has 360-degree coverage with a pickup range of 3 metres, and the microphones have a cardioid response from 0 to 8,000 Hz. For a table seating six people on two sides, plan microphone positions so each speaker sits within a single microphone's 3-metre zone, and a free site survey can confirm placement before installation.

How long does the battery last and can the microphones be charged wirelessly?

The built-in lithium batteries provide up to 10 hours of run time, and the manufacturer lists the microphone units as wireless charger compatible. The warranty includes a 1-year battery guarantee. Before ordering, confirm which wireless charger model you need, since charger compatibility should be checked against the exact model in your quotation.

Which computers and conferencing software does it support?

The system is listed for Windows 7, Windows 8, Windows 10 and Windows XP, and for Mac OS X 10.7 and later. The manufacturer states it supports most computer audio software, including Skype, Zoom and TeamViewer. Check that your video conferencing platform runs on a listed operating system before requesting a quote for several rooms.

Can it be used in a hot room in Doha during summer?

The recommended operating temperature is 5°C to 44°C, with humidity of 20 to 85% and no condensation, and the storage range is -10°C to 55°C. Summer temperatures in Doha can exceed 45°C outdoors, so install the controller in an air-conditioned meeting room away from sun-facing windows and direct airflow from vents.

Is it suitable for a boardroom in West Bay joining calls with teams abroad?

Yes, it suits this use. The system supports full duplex communication across all four microphone units, meaning both ends of a call can speak at the same time, and it includes 256ms echo cancellation and dynamic noise reduction. These features help a West Bay boardroom hold video calls with overseas colleagues without audio cutting out during discussion.

Would it work for a seminar room at a university in Education City?

A seminar room in Education City can use this system when a lecturer and visiting speakers need to join a remote panel from a single table. The four microphones cover a table with a 3-metre range each, and the controller provides microphone mute and volume keys, so the lecturer can manage the room without moving to the computer.

What warranty comes with the Cleartalk ASP-04D-4S?

The source data specifies a 3-year warranty and a 1-year battery guarantee. As with all products supplied by SmartRooms Qatar, the manufacturer warranty applies. Ask for the warranty details to be included in your quotation, so procurement teams have the terms in writing when preparing a purchase order.

Can a government ministry order this through a purchase order or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment can be made by bank transfer, cheque or purchase order. Send the room list and the number of microphone sets with your request, and the team will issue a quotation usually within one working day.

Do you need a site survey before installing this system?

A site survey is useful for this product because microphone placement depends on table shape and seating distance. SmartRooms Qatar offers free site surveys and professional installation across Qatar. Surveying the room before ordering helps confirm controller position, microphone spacing and whether the room is air-conditioned within the 5°C to 44°C operating range.

Is this model suitable for a training centre in the Industrial Area?

It suits a small training room with one table and a limited number of speakers. In a Industrial Area training centre, the 3-metre pickup range and 10-hour battery make it practical for instructor-led sessions. For a large classroom or a noisy workshop, ask for a quote to compare alternatives, because the rated noise level and room acoustics affect performance.
