The result of continuous, in-depth research to challenge conventions, Meridian Audio has launched a new technology upgrade for its architectural range.
High-Power Array (HPA) optimises the output and sound coverage when three Meridian architectural loudspeakers are positioned in close-proximity array configuration.
Integrators designing large home cinemas aim to achieve high SPL targets across the entire listening region without distortion. CEDIA guidelines recommend a THX Reference level 105dB for the main listening position.
This can raise a number of challenges that typically requires the need to move to compression drivers that lack the required high frequency extension, resolution, and clarity; a deeper installation depth for larger high SPL speakers; and a greater number of larger power amps in the rack that generate more heat.
These challenges can be resolved with Meridian’s new HPA technology, allowing integrators to install three identical DSP loudspeakers in a stack or array configuration while ensuring minimal interference and spectral variation between speakers, giving an even response throughout the room. The HPA installation method also enables the installer to maintain the 100mm mounting depth and the additional channels don’t require any extra equipment in the rack.
HPA is available for use with Meridian’s architectural range, including the DSP520.2, DSP640.2, DSP750, and DSP730.
Assigned the ‘primary’ product, the three loudspeakers are installed with the centre speaker and the two outer speakers are classed as the ‘secondary’ products. This is the same whether installed vertically or horizontally. To allocate a role, the integrator needs to send one RS232 command to each individual loudspeaker within an array.
Installation of the speakers should see them positioned 50mm or less apart – the closer the speakers, the better the performance. When installing the loudspeakers horizontally, the listener’s ears should be positioned directly in line with the primary loudspeaker, and at a distance of at least four metres from the array. For vertically mounted speakers, the line should target the tweeter drivers.
