MLA’s practical implementation uses very steep, VanishingPointTM, FIR filters. They are not actually brick-wall, because of the
effects of brick-wall filters on transient response. Listening tests confirm that the two devices are impossible to locate separately,
but sound like a single acoustic source, located at the point in space at which we have optimised the FIR filter.
MLA’s VanishingPoint FIR filters give us the freedom to physically separate the mid and HF horns, so they do not compromise
each other’s dispersion pattern, yet achieve the spatial performance of a single device – giving us the best of both worlds.
Amplifier Module
The amplification and control module is an entirely self-contained section. This may be removed by unscrewing the rear panel
which also holds the weather cowl in place. Once unscrewed the module is quickly disconnected using the pair of Neutrik NL8
connectors which connect the amplifier outputs to the drive units. This means that field replacement of the module is quick and
easy in the unlikely event of a module failure.
Each MLA is fitted with a 6-channel amplifier module. Its Class D circuitry delivers a total of 3kW continuous and 6kW peak
output, whilst producing significantly less heat than a linear output stage design. All channels share the same circuit topology
and are driven from the same power supply. This configuration effectively shares the total power available between the LF, mid
and high frequency channels - providing high continuous power for the low frequency channel and high peak power for the mid
and HF channels.
