It suits meeting rooms and corporate digital signage across Doha and Lusail. Request a quote for a matched setup.

What the SP-RM3a adds to a Sharp display

The SP-RM3a is a stereo speaker system that mounts on the rear of a Sharp large format display. It is an accessory rather than a standalone audio product, designed to pair with the compatible PN-LA752 and PN-LA862 panels listed by the manufacturer. It improves sound for video conferencing and for corporate digital signage. Because the unit sits behind the panel, the front of the display stays clean while the audio comes from the screen itself.

Specifications that matter for room planning

These are the figures from the manufacturer data:

Input: 40 W maximum long-term power
Impedance: 8 Ω
Frequency response: 0.08 to 20 kHz
Sound pressure level: 72 dB
Dimensions (W x H x D): 370 x 60 x 60 mm
Weight: 1.2 kg
Warranty: 3 years, matching the display warranty

A 40 W input and 72 dB sound pressure level suit a medium-sized meeting room or a corporate lobby where announcements and video calls must be heard clearly. The unit is 370 mm wide and weighs 1.2 kg, so it is light enough to fit into a standard panel installation, but the rear clearance should still be checked on site.

Where it fits in Qatar

Three realistic setups show where the SP-RM3a earns its place:

A training centre in Lusail equipping a meeting room with a compatible Sharp display, where staff join video calls with colleagues abroad and the sound must reach the far end of a conference table.
A hotel lobby in West Bay running digital signage with announcements, where the speakers add audio to a visual loop without adding external speakers.
A private school in Al Khor fitting out a staff room, where the speakers stay hidden behind the panel on most display sizes.

Planning the installation

Before ordering, confirm that your display model is one of the two panels the manufacturer lists as compatible, and check the exact rear clearance against the unit's dimensions. On a 40-inch display the speakers remain visible from the front because of the back chassis design, which affects how a small room looks. The manufacturer describes the unit as quick and easy to assemble. The data does not list power requirements or operating environment, so confirm those with the SmartRooms Qatar team during a free site survey, which is especially useful for heavier panels and walls where the cable route needs checking.

Questions about SP-RM3a

What is the Sharp SP-RM3a used for?

The SP-RM3a is a rear-mounted stereo speaker system that adds sound to compatible Sharp large format displays. Sharp positions it for video conferencing and corporate digital signage, so the room gets audio from the display itself rather than from a separate speaker set. It is an accessory, so it needs a compatible display and is best quoted alongside that panel.

Which Sharp displays is the SP-RM3a compatible with?

The manufacturer data lists two compatible models: the PN-LA752 and the PN-LA862. Before ordering, confirm your exact display model, since the data lists only these two panels. Matching the model at quotation stage means the rear fit is right from the start and avoids changes on site.

What power input and impedance does the SP-RM3a have?

According to the manufacturer data, the SP-RM3a has a maximum long-term power input of 40 W and an impedance of 8 Ω. These figures set the continuous power the unit accepts, which is the number to check when comparing it with a room's needs. The speakers are described as active, and the SmartRooms Qatar team can explain connection details when preparing your quotation.

Is a 72 dB sound pressure level enough for a training room in Lusail?

The data lists a sound pressure level of 72 dB and a frequency response from 0.08 to 20 kHz, which is suitable for speech and clear announcements in a small to medium training room. The data does not give room size or coverage area, so the team should check the layout during a site survey. For a large lecture hall, request a site review before ordering.

Will the speakers be visible on the display?

It depends on the display size. According to the manufacturer data, on a 40-inch display the speakers stay visible from the front because of the back chassis design. On other display sizes they are concealed behind the panel. If a 40-inch screen sits in a reception area where appearance matters, confirm the finished look with the team before you order.

How big and heavy is the unit, and should a site survey be arranged?

The unit measures 370 x 60 x 60 mm and weighs 1.2 kg according to the data. Those dimensions are small, but the clearance behind the display and the cable route still need checking on site. SmartRooms Qatar provides free site surveys, which are worthwhile before fixing a heavier panel to a wall in a new office or school.

Is the SP-RM3a suitable for a boardroom in Msheireb with a video conferencing system?

Yes. The unit is focused on video collaboration, which suits a display used for calls, where audio must reach every seat around the table. The data does not give seating or room size, so the team should confirm coverage against the room layout and chosen display size before a quotation is issued.

Can the SP-RM3a support digital signage in a hotel lobby in West Bay?

Yes. The manufacturer positions the SP-RM3a for corporate signage applications, so it suits a West Bay hotel lobby where a display loops welcome messages, event listings or announcements. Because it mounts on the rear of a compatible Sharp panel, the front of the screen stays clear. Confirm the display model and lobby layout before ordering.

Would it suit a private school in Al Khor fitting out a staff room?

Yes, where the display is used for meetings, training material or notices, the SP-RM3a adds audio without separate speakers. Plan the mounting height and rear clearance with the installer before the panel is fixed to the wall. A quotation can be requested for the compatible display and the speaker system together.

Can it be installed near a window or in a very hot area?

The data does not list an operating temperature for the SP-RM3a, so it should not be assumed suitable for hot areas. Summer temperatures in Qatar can exceed 45°C, and sun-exposed windows can raise room temperatures considerably. Ask the SmartRooms Qatar team to confirm the installation environment and the unit's operating range before placing an order.

What warranty applies to the SP-RM3a?

The manufacturer data gives a warranty of 3 years, which matches the warranty on the display. Products are covered by the manufacturer's warranty. Keep your purchase records and invoice with the quotation, so the display and speakers can be checked together if a warranty claim is needed.

Can a government body or school buy the SP-RM3a with a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including through Monaqasat, and quotations are usually issued within one working day. A ministry or school can request a quote for the SP-RM3a with its matching Sharp display. Payment can be made by bank transfer, cheque or purchase order, and delivery covers all eight municipalities of Qatar.
