AXYS T-2212 data sheet rev 1.1 / GvB / Dec. 15th 1995

T-2212 Architectural and engineering specifications The loudspeaker unit shall be of the two-way active type with integrated electronics, two 12” low/mid speakers and one 2” ferrofluid cooled driver with carbon-fiber diaphragm. Specially developed horns made of fiberglass reinforced epoxy and coated in order to dampen resonance’s shall be mounted on each transducer. The horns shall have an exponential area increase and a constant directivity over a wide frequency range. Arrayability shall be guaranteed by a well defined frequency independent horizontal opening angle in exact correspondence with the shape of the cabinet. The complete electronics shall be mounted on a chassis which is placed in a separated part at the backside of the enclosure. Electronics shall consist of active filters to implement crossovers and equalization, protection circuitry and three power amplifiers coupled to two independent power supplies. The filter section shall include a ‘cluster configuration’ switch which enables the user to compensate for coupling effects in the low-mid frequency range when using multiple unit clusters. Protection shall consist of two Dynamic Level Control (DLC) circuits that limit the dissipated mean power of the transducers to a safe value, DC protection on each of the amplifier outputs, high chassis temperature and high voltage on the mains supply. A LED on the front and rear side shall display the status of all protection circuits. The balanced signal input connector shall be a 3p female XLR type (p2 = +, p3 = -, p1 = gnd), the full-range signal output link connector shall be a 3p male XLR type (p2 = +, p3 and p1 = gnd). A hard-wired bypass relay guarantees the signal transfer to the link output in any condition. A mains voltage switch (115/230 V) shall be implemented on the outside of the unit and the mains connector shall be a male DO-3 type. All connectors shall be grouped together at the lower side of the chassis. The enclosure shall be constructed of laminated birch plywood reinforced with bracing and two internal aluminum frames to which eight rigging frame attachment tracks are connected (four on top and four on the bottom). It shall contain six recessed handles and shall be trapezoidal shaped to facilitate the construction of clusters. A passive convection system shall ensure an efficient transfer of the heat generated by the transducers and the electronics. The front of the enclosure shall be covered with open cell foam mounted on a protective perforated steel grill. The enclosure shall be finished with a polyurethane coating. The complete loudspeaker unit shall meet the following performance criteria: Frequency range of 130 - 18k Hz on axis (+/- 3 dB), max. SPL at 1m of 136 dBSPL continuous and 139 dBSPL peak, - 6 dB coverage angle of 35o horizontal by 32o vertical averaged 1k to 15k Hz. Dimensions are 56.7” (1440 mm) H x 21.3” (540 mm) W x 26.4” (670 mm) D, trapezoidal shaped. Weight 203 lbs. (92 kg). The loudspeaker unit shall be the AXYS model T-2212.
