It consists of a 160 litre speaker enclosure and a 7U 19" equipment rack which contains active crossovers, three channel power amplifiers and driver protection circuitry.
The amplifier panel also features a 12V trigger switching function. The loudspeakers are designed for flush mounting in the front wall, although they may be used free standing, and can produce peak sound pressure levels in excess of 125 dB.
Bass, midrange and treble controls are included to allow the speakers to be matched to the acoustic conditions in different control rooms.
