In retail, hospitality and wellness applications, music delivery is crucial.

During the design phase, we evaluate the diffusion areas, the possibility of integrating acoustic speakers at architectural level, the division of the music diffusion areas by volume and content, the level of loudness and frequency extension of music reproduction necessary to maximise the audience experience in coherence with the Branded Content Marketing conceived by the client.

The bottleneck

Unfortunately, we know what the bottleneck is when approaching this type of project, the distribution so called at 100V or constant voltage. While new amplification technologies have succeeded in eliminating output transformers from amplifiers, loudspeakers for distributed logic applications continue to be equipped with them. transformers built into loudspeakers are limited in power output, tend easily to saturation, narrow the bandwidth, and completely obliterate the microdynamics that make for a natural sound message.

The solution exists and is patented by the Canadian company Zero-Ohm which makes special passive impedance adapters that allow any constant-impedance amplifier to be interfaced with distributed lines of low-impedance acoustic loudspeakers, including sub woofers! Impossible? Quack magic?

Big Sound from a Small Speaker?

The design of a distributed logic sound diffusion system generally requires a special degree of attention to the architectural integration of the necessary acoustic diffusers, acoustic diffusers that in most cases are selected for recessed installation in false ceilings or walls. Generally the client's request is for the diffuser to be small in order to achieve a concealed installation with limited interference with the lighting fixtures and aeraulic systems placed in the false ceiling.

Small speaker, small sound...how can I meet the client's acoustic expectations? Simple, using loudspeakers with Sonic Vortex® technology of the producer Beale Street Audio. A wide range of high-quality low-impedance in-wall and in-ceiling/pending loudspeakers featuring the patented Sonic Vortex® transmission line woofer acoustic loading configuration typical of large floor-standing Hi-Fi loudspeakers.

The benefit? +6/9 dB of sound pressure in the mid-band compared to loudspeakers from manufacturers using traditional bass reflex technology.

What about amplification?

In distributed logic projects, several diffusion zones must generally be considered, which can be differentiated by reproduction volume and content; amplification must therefore be multi-channel, as far as possible realised with compact amplifiers, capable of integrating DSP logics for managing equalisation and limiterand, above all, it must have a muting contact input for interfacing with EVAC audio systems that might coexist in the same rooms.

The perfect answer is CloudPower of the Belgian manufacturer Apex, a line of multi-channel amplifiers with exceptional sonic capabilities thanks to the patented GlidePath direct drive design, has all the necessary DSP processes built in to guarantee excellent acoustic results.

And if that were not enough:

• It has a built-in network player that can be set as a Spotify or Airplay player
• Available in Dante version
• Configurable via web browser, even remotely thanks to the ApexCloud free of charge.

Do you want to enter into a maintenance contract with your customer for one or more outlets/gyms/hotels where you have installed a public address system? Imagine being able to monitor the functional status of the amplifiers you have installed wherever they are in operation, imagine being able to do this simply from your desk in your technical office; with Apex CloudPower amplifiers remote control is already a reality and at no extra cost.
