VERIS 2 models should be chosen with the best dispersion patterns to cover the audience
evenly. Each loudspeaker should be carefully focused towards the listeners while being
careful to keep acoustic energy away from walls, ceilings, and other reflective surfaces,
including physical obstructions that are caused by architectural elements (such as
columns) or furnishings.
In many cases, locating all the main loudspeakers in a central location will simplify the
installation, mechanically and electrically, while also improving acoustical performance.
This is typically referred to as a center cluster design. Centralized clusters tend to create
very coherent sound sources because all the energy is emanating from a single location.
However, not all applications and venues are suitable for central clusters. In some cases
it's more effective to distribute the loudspeakers throughout the venue, to maintain a
more even distribution of SPL. The factors that drive the optimal design decisions can be
simple or quite complex, and include such elements as ceiling height, room reflectivity,
size of the venue, location of live sound sources (if any), distance between distributed
loudspeakers, and much more.

RECAPPING: After determining the loudspeaker complement and positioning, it's important
to select power amplifiers that are large enough to achieve the required SPL with enough
headroom to avoid clipping. The use of a limiter to protect the loudspeakers from excessive
energy is very important, as is the use of external high-pass filters. Proper wiring design is
also essential, and gain adjustment is important to achieve the best signal-to-noise ratio.
dSPEC226 – THE SIMPLE AND EFFECTIVE ANSWER
Community's dSPEC226 loudspeaker processor solves many installation issues in moments,
where using other signal processors might take hours... or even days.
dSPEC226 is a full-featured, multi I/O DSP loudspeaker management system that was
designed to be the optimal companion to any Community loudspeaker system. In particular,
each dSPEC unit contains a library of presets created at the factory intended to optimize the
performance of each model of Community loudspeaker. By simply adding the various model(s)
of loudspeaker(s) that are in your installation from a drop-down menu, you're already more
than "half-the-way there." dSPEC then offers delay and extensive equalization capability to
optimize the system for the room it's installed in.
dSPEC226 also provides extensive electronic protection algorithms (three levels of protective
limiters), that at the push of a button, adjusts protection thresholds and other parameters to
each amplifier and speaker in the system.
Remote control of user-presets is also possible, along with a host of other features – far too
many to describe in full, in this Manual. Please call us or visit our website to see how
dSPEC226 can make your job far easier – with a far better outcome – than using a generic
loudspeaker processor.
COMMISSIONING THE SYSTEM
Commissioning is the process of optimizing the performance of the system after it has been
installed. There are several steps in commissioning. First is verifying the proper operation of
every system component, and then adjusting system gains and levels.
The last step in system commissioning is known as system equalization or "voicing."
Equalization is the process of adjusting the frequency response of the system to optimize voice
intelligibility or musical sound quality (or both). Note that VERIS 2 loudspeakers are factory
voiced to optimize their speech intelligibility and musical sound quality. For this reason, many
designers find they can minimize overall system equalization and still achieve excellent voice
intelligibility and musical sound quality without extensive EQ. However, in the end this is a
function of the room acoustics. A large, highly reverberant room will require more attention
than a small, dry acoustic space.
