Meyer Sound has expanded the Precision Toolset accompanying its Leo Family line array systems, adding proprietary Low-Mid Beam Control for assuring uniform front-to-back coverage and improving workflow for maximum efficiency in time-critical touring applications.
The Precision Toolset is implemented in the latest releases of Meyer Sound’s Mapp XT acoustical prediction program and Compass control software for the Galileo Galaxy network platform. Applicable across the Leo Family of loudspeakers – from the flagship Leo to the compact Lina – the enhanced components help ensure an optimum audience experience using scalable systems.
The new toolset integrates three key features that enhance amplitude and phase compatibility within the family of Meyer Sound loudspeakers and perform beam-steering of arrays. The EQ Starting Points feature enables the different models of speakers to start with a common target frequency response curve (amplitude compatibility). Delay Integration performs the same function in the phase domain (phase compatibility), relieving users of the challenging task of precise phase response optimization.
The newest core component of the toolset is digitally implemented Low-Mid Beam Control (LMBC). Using variants of advanced DSP algorithms developed for Meyer Sound’s digital beam-steering CAL column array loudspeakers, LMBC corrects the understeered low-mids (an inherent side effect in all curvilinear arrays) by lifting and/or spreading the beam. By introducing precisely calculated frequency-dependent phase response filters to individual or paired loudspeakers in the array, the low-mid coverage pattern is precisely matched to the higher frequency range. The result is seamless and uniform front-to-back coverage. LMBC has been proven in three years of beta testing, including several large-scale concert tours by major artists.
‘LMBC presents an elegant digital solution to this enduring challenge facing modern main array designs,’ says Meyer Sound Director of System Optimization, Bob McCarthy. ‘Once your coverage is set for higher frequencies, you simply select the appropriate control settings and the low mid-frequencies instantly conform for a uniform front-to-back response.’
LMBC is fully implemented in the newest releases of Meyer Sound’s Galaxy Network Platform (v1.3.0), Mapp XT acoustical prediction program (v1.2.0), the companion Compass control software (v4.3.1), as well as in v2.3.2 of Compass Go, the remote-control application for iPad.
The new software releases also calculate the loads when using pull-back frames. This allows for the extreme down-tilt array configurations often necessitated for clear sightlines or coverage of specific seating areas. System designers now can configure such arrays in Mapp XT and obtain accurate modelling of array coverage as well as hang point loading data to assure that Meyer Sound rigging hardware is stable and secure. Also added to the toolset, on the hardware side, is the GEB-Leo extender bar, which enables rigging of Leo arrays with greater down- or up-tilt without use of additional rigging points or motors.
The MDM series makes for elegant easy-to-use power and signal distribution for Meyer Sound systems of any size. It also provides connection points for laser/inclinometer instruments as well as dedicated RMS data for seamless integration with RMServer for comprehensive, network-based monitoring and diagnostics to maintain long-term loudspeaker reliability.
‘From the outset, the Leo Family has offered a complete toolset to assist at every step of the way, from in-depth user education and system design through field deployment,’ says McCarthy. ‘Now more than ever before, the Leo Family provides sound designers, consultants, integrators and rental houses with an integrated and fully scalable solution.’
