AMPLIFICATION
Normally, LA8
V2
systems are also supplied with NEXT power-rack
mounts already configured for optimum performance, according to the
configuration chosen by the customer. NEXT-Proaudio recommends using only
NEXT-Proaudio approved amplifiers and signal processing units, and only
provides signal processing configuration files for approved signal processing
units.
The LA8
V2
element is an active two way system, where one of those is a passive
two way system. The high frequency band is reproduced by two 1” drivers connected in
serial, having a combined nominal impedance of 16Ω. The mid/low frequency is reproduced
by a passive two-way system composed by two 8” drivers and a passive crossover that will
behave like a dynamic impedance system going from 4Ω nominal impedance in the lower
frequencies to approximately 8Ω nominal impedance in the higher working frequency range.
This passive system achieves some predefined goals. In the lower frequencies,
both speakers reproduce, achieving a higher impact on the bass range. In the mid
frequencies, virtually only one speaker is reproducing, reducing the dipole effect both
speakers would create, providing an outstanding response linearity to the LA8
V2
within its’
dispersion field.
Acoustically speaking, the LA8
V2
line-array element was designed to work in a
minimum of four unit arrays. Only then can you achieve enough vertical dispersion for the
system to be usable. Also line-array effect will be reduced with less than 4 units. In terms of
powering, the elements are best used in groups of two. When wired in parallel, the mid/bass
speakers will have a nominal combined impedance of 2Ω at the lowest frequencies. That’s
the lowest impedance most amplifiers can withstand. Taking this into consideration, see the
table below:
