Speakers & Audio Systems

A professional audio system has four parts: microphones and sources, a mixer or processor, amplifiers, and loudspeakers. Meeting rooms add echo cancellation, and commercial spaces add wall controls for each zone.

For example, a meeting room might use ceiling microphones, a Bose ControlSpace EX-1280C processor with 12 echo-cancelling channels, a Shure MXN-AMP PoE+ amplifier and ceiling speakers, while a ballroom uses wireless microphones, a mixer, amplifiers and line arrays or columns.

This collection covers Shure, JBL Professional, d&b audiotechnik, Bose Professional and Electro-Voice. Shure makes up more than half of the 2,319 products, from wireless microphone systems to conferencing microphones and spare parts.

CorporateAV.ae is an authorised dealer of Shure in the UAE, and a supplier of genuine JBL Professional, d&b audiotechnik, Bose Professional and Electro-Voice products.

Use ceiling speakers for even background music and speech across offices, shops, hotels and meeting rooms, usually on 70 V or 100 V lines. Use cabinets, columns or line arrays for ballrooms, auditoriums and events that need higher levels and controlled coverage.

For example, a Bose DesignMax DM6C ceiling speaker covers 120° with taps up to 80 W, while a d&b Y8 line array module reaches 139 dB for large venues.

Dante is a networked audio standard that carries many audio channels over a normal Ethernet network, so microphones, processors and amplifiers connect through network switches instead of separate analog cables.

In this range, Shure ULX-D and Axient Digital receivers, Bose ControlSpace EX processors, Bose PowerShare amplifiers and the Yealink AP08 support Dante. The Bose EX-1280C handles 64 Dante inputs and 64 outputs.

A 70 V or 100 V system runs many speakers in parallel on one amplifier channel, with a transformer tap on each speaker setting its level. It suits offices, retail, hotels and other spaces with many ceiling speakers.

Bose DesignMax and JBL Control ceiling speakers offer taps such as 2.5 W to 80 W at 70 V, and Bose PowerShare amplifiers switch each channel between 70 V / 100 V and 4 to 8 Ω operation.

For occasional presentations, a Shure BLX system gives up to 14 hours on two AA batteries and up to 12 systems per frequency band. For daily use and confidential meetings, Shure SLX-D+ adds AES-256 encryption and up to 8 hours per charge or battery set.

Larger venues with many channels use ULX-D or Axient Digital receivers with Dante. Choose the frequency band for the country of use with Shure's Wireless Frequency Finder.

A meeting room with video calls needs acoustic echo cancellation on every microphone, which comes from a conferencing processor or from the microphone system itself.

The Bose ControlSpace EX-440C has 8 echo cancellers and the EX-1280C has 12, both with USB, VoIP and Dante. The Yealink AP08 has 8 AEC channels and powers up to 3 audio devices with PoE+.

Use speakers rated for outdoor exposure. The Bose ArenaMatch Utility AMU208 is rated IP55, Bose ArenaMatch AM10, AM20 and AM40 modules are rated for direct-exposure outdoor installation, and the JBL AWC129 is rated IP56.

For bass outdoors, the Bose MB210-WR subwoofer is rated IP55. For coastal and pool areas, also plan for sun, humidity and salt air at cable entries and brackets.

Add up the loudspeaker load per channel: the transformer taps on each 70 V or 100 V line, or the power rating of each low-impedance cabinet, and choose channels rated above that total.

Amplifiers here range from the PoE+ Shure MXN-AMP at 14.5 W for meeting rooms, through the Bose PowerShare PS604D with 600 W shared over 4 channels, to the d&b D80 at 4 × 4,000 W into 4 Ω for large venues.

An audio design starts with the floor plan, ceiling height and type, and whether the space is indoor or outdoor, plus the use: speech, background music, live music or video calls.

Add the number of microphones used at once, the number of zones that need separate levels, the call platform for meeting rooms, and the available rack space, network ports with PoE and mains circuits. With these, speakers, microphones, processing and amplifiers can be chosen together.
