FBT highlights product evolution
Evolving from the FBTMaxX Series of loudpeakers, FBT EvoMaxX speakers feature new woofers and more powerful Class-D amplifiers. An EvoMaxX digital signal processor with four presets also provides quick equalisation contours for any acoustically challenging venue.
EvoMaxX’s polypropylene cabinets feature a monitor taper designed to ensure that they can be used at front of house for a main sound system, as stage floor monitors or within permanent installations.
Additional options are also available for extending low frequency response in the shape of the Subline 15S/15Sa and 18S/18Sa, all of which boast birch plywood enclosures with 15-inch band-pass and 18-inch reflex designs respectively. Both are available in powered or passive versions.
The EvoMaxX series consists of four powered and three passive models which vary in woofer size but all feature a 1-inch B&C HF driver. The exception to this is the EvoMaxX 9Sa powered 15-inch subwoofer.
The cabinets feature Class-D 400W LF and 100W HF power amplifiers with switch mode power supplies. These amplifiers boast a lightweight design with passively cooled circuitry. A further highlight are the filter algorithms including dynamic equalisation at low frequencies and advanced energy control which, according to the manufacturer, ‘allows high SPL while granting reliable and distortion-free audio reproduction’. The digital limiter algorithms and increased amplifier power output have also reportedly created an increase in total SPL.
For the manufacturer, the major highlight is the new DSP which includes four factory presets to help the EvoMaxX range to accommodate a variety of applications. The presets include ‘Original’, which corresponds to the typical ‘MaxX’ sound for use in general applications; ‘Floor’ for use as a stage monitor; ‘Vocal’, which provides increased intelligibility for vocals and speech; and ‘Warm’ which reportedly gives a full-bodied response to the low-mid frequencies while treating high frequencies less aggressively.
Staying with FBT’s processing technology, the DLM26 is a DSP-based two input, six output digital loudspeaker management processor aimed at fixed installations and live events. It is a 1RU unit with PC remote control capabilities.
The DLM26 features AKM5392 24bit A/D converters and AKM 4396 24bit D/A converters coupled with 24-bit conversion ensure a dynamic range greater than 110db. The unit can work in Standard Mode or in DCL Mode. Standard mode permits the user to configure the crossover in 2x2 way + SUB, 2x3 way or 6way, the input L, R, L+R are freely assignable to each output.
In DCL mode the unit can be configured in 3-channel DCL, 2-channel DCL + 2-channel standard, 1-channel DCL + 4-channel standard. DCL mode means double compressor limiter. Each DCL channel has a double band limiter and compressor with assignable LO/HI split frequency. With DCL mode it is possible to set two different thresholds of protection for the woofer and driver with the split frequency corresponding to the passive crossover frequency.
