AXYS UFM-265 data sheet rev 1.1 / GvB / Dec. 15 th 1995
UFM-265
Architectural and engineering specifications
The loudspeaker unit shall be of the two-way active type with integrated electronics, two direct-radiating 6.5” low/mid speakers in a vented enclosure and one 1.1” ferrofluid cooled soft-dome tweeter, optimized for high power handling.
The complete electronics shall be mounted on a chassis which is placed in the backside of the enclosure. Electronics shall consist of active filters to implement crossovers and equalization, protection circuitry and two power amplifiers. Filter section shall include a ‘contour’ filter push-push switch forming an integral part of the volume control potentiometer which enables the user to equalize the response in the mid frequency band centered around 800
Hz. Protection shall consist of a Dynamic Level Control (DLC) circuit that limits the dissipated mean power of the transducers to a safe value, an overload monitoring circuit that reduces the input gain by 8 dB if an input overload occurs, an amplifier DC protection circuit and a high chassis temperature protection circuit. A bi-color LED at the rear shall display the status of the ‘contour’ filter, the DC- and the temperature protection. The balanced signal input connector shall be a 3p female XLR type (p2 = +, p3 = -, p1 = gnd) and the fullrange signal output link connector shall be a 3p male XLR type (hardwired to input connector). The mains connector shall be a male DO-3 type and the mains link connector shall be a female DO-3 connector. All connectors and controls shall be grouped together.
The enclosure shall be constructed of laminated birch plywood and be shaped as a floor monitor with a floor to baffle angle of 30 o . It shall be equipped with two handles and nonskid aluminum framed profile at the bottom side. 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 criteria:
Frequency range of 75 - 20k Hz on axis (+/- 4 dB), max. SPL at 1m of 116 dB uous and 119 dB
SPL
peak, - 6 dB coverage angle of 100 o horizontal by 120 o continvertical averaged 2k to 15k Hz. Dimensions are 9.6” (243 mm) H x 15.6” (397 mm) W x 15.7” (400 mm) D. Weight 29 lbs. (13 kg).
The loudspeaker unit shall be the AXYS model UFM-265.
