Overview
The AISPEECH MC04 is a white ceiling microphone array for standard classrooms and compact teaching spaces. Its 24-element MEMS array picks up the teacher's voice from a podium area, while built-in AI noise reduction and feedback suppression help keep audio clear. It draws power over PoE+ and connects to existing amplifiers and recording systems through analog I/O, making it a practical choice for classroom audio upgrades.
What the MC04 captures in a classroom
The MC04 is a ceiling-mounted microphone array built for standard classrooms and compact teaching spaces. Rather than relying on a handheld or lapel microphone, it sits above the teaching area and picks up the teacher's voice as they move between the desk and the board. Its 24-element MEMS array can be configured with pickup zones that concentrate coverage around the teaching area.
Processing that keeps speech intelligible
Built-in audio processing covers AI noise reduction, dereverberation, feedback suppression, echo cancellation, automatic gain control and intelligent mixing. In practice, this works to reduce writing noise, fan noise and room echo, and to suppress the squeal that appears when a microphone sits close to a loudspeaker. The data rates noise suppression at 35 dB and the signal-to-noise ratio at 73.9 dBA, with audio sampled at 48 kHz.
Fitting it into existing classroom audio
The MC04 provides four analog inputs and two analog outputs on Phoenix terminals, so it can feed an existing amplifier, speakers, an interactive display or a recording system without replacing the rest of the setup. Its single network port is a 10/100/1000M RJ-45 port that carries PoE+ power, and up to two units can be cascaded. The package includes four Phoenix terminals, four sling sets, a screwdriver, a remote control and a manual.
Mounting options and planning
- Flush installation in a suspended ceiling grid
- Steel rope suspension below the ceiling
- Pole mounting below the ceiling
The unit weighs under 2 kg and measures 270 × 270 × 54.75 mm in white, a low profile that suits most ceiling finishes. Plan the mounting point above the teaching area and check cable routing to the network switch and amplifier before installation. The SmartRooms Qatar team offers a free site survey to confirm position and mounting method. The operating range is 0°C to 40°C with 20% to 95% RH humidity, so the room should stay air-conditioned; confirm the installation environment with the team before mounting.
Where it fits in Qatar
- A private school in Al Wakrah upgrading a standard classroom for 30 to 50 students
- An international school in Lusail fitting out a compact teaching room
- An Arabic-curriculum school in Al Rayyan adding clear back-row audio to existing classrooms
The data recommends around 650 sq ft for a classroom of 30 to 50 persons. Schools and government entities ordering several units can issue a purchase order (LPO), and payment is accepted by bank transfer, cheque or purchase order. Request a quote from SmartRooms Qatar with your room sizes, classroom count and mounting preferences, and the team will respond with a quotation usually within one working day.

What is the AISPEECH MC04 used for?
It is a ceiling microphone for standard classrooms and compact teaching spaces. It captures the teacher's voice from above, so the teacher does not need to wear or hold a microphone, and it sends the audio to an existing amplifier or recording system. The data recommends it for classrooms of 30 to 50 persons, around 650 sq ft.
Would the MC04 suit a lecture theatre at Education City?
The data sets its recommendation at classroom scale, around 650 sq ft for 30 to 50 persons, so it is built for everyday teaching rooms. Before buying for a larger hall, ask SmartRooms Qatar to confirm the fit against your room size and layout.
What is the difference between the reinforcement radius and the pickup radius?
The data gives a recommended reinforcement radius of 2 m and a recommended pickup radius of 3.5 m. Place the podium inside the pickup area, and use the reinforcement figure when planning how amplified speech reaches the back row. Confirm the exact position during the free site survey.
Can a teacher move around the room while teaching?
Yes. The array is designed to pick up voice around the podium, so a teacher can move between the desk and the board and stay clearly heard. Pickup zones can also be configured to focus coverage on the teaching area.
Does the MC04 need a separate power adapter?
The package does not list a separate adapter. The unit is powered through its single 10/100/1000M RJ-45 port using PoE+, and it consumes 12 W. Before ordering, confirm that the network switch in the classroom supports PoE+.
Will it work with the amplifiers and speakers already in our school in Al Rayyan?
It has four analog inputs and two analog outputs on Phoenix terminals, so it can work with existing amplifiers, speakers, interactive displays and recording systems. The package includes four Phoenix terminals. A site survey will confirm which connections your current system needs.
Can more than one unit be linked together?
Yes, up to two units can be cascaded. During the free site survey, the SmartRooms Qatar team can review your room layout to decide whether one or two units suit the space.
What mounting options does the MC04 offer?
Three installation methods are supported: flush installation in a ceiling grid, suspension with steel ropes below the ceiling, and a pole below the ceiling. The package includes four sling sets and a screwdriver. The unit weighs under 2 kg and measures 270 × 270 × 54.75 mm.
How does the MC04 cope with Qatar's summer heat?
The operating range is 0°C to 40°C with 20% to 95% RH humidity, so the room housing the unit should stay air-conditioned, particularly in schools in Al Khor or Mesaieed where summer temperatures are high. Confirm the installation environment with the SmartRooms Qatar team before mounting.
What noise performance does the MC04 specify?
The data lists 35 dB noise suppression and a signal-to-noise ratio of 73.9 dBA, with a 48 kHz sample rate. The AI processing targets writing noise, page turning, fan noise, reverberation and feedback, which are common disturbances in classrooms.
How can a school or government entity buy several units?
Schools and government entities in Qatar can issue a purchase order (LPO) for several MC04 units. Payment can be made by bank transfer, cheque or purchase order. Send the number of rooms, their sizes and your mounting preferences, and the team will reply with a quotation usually within one working day.
How do I choose between flush and suspended installation?
The choice depends on your ceiling. Flush installation uses the ceiling grid, while steel-rope and pole installations hang below the ceiling. A free site survey confirms which method suits each room before the quotation is finalised.
