SD2

The SD-2 loudspeaker system is a compact high-power device designed to perform in a wide range of public address and sound reinforcement applications. It is a bi-amplified system consisting of mid-low, high frequency vented enclosure including a proprietary 12" low frequency cone driver and a 3" diaphragm high frequency driver with a 90° x 40° CD horn. The enclosure is black epoxy painted fitted with handles on the side and with four aircraft pan fittings.(Two on top and two on bottom). The front of the speaker is protected by a heavy duty metal grill, covered with charcoal grey foam.
The SD-2 loudspeaker system is designed to operate with the P113 or P212 processor unit, which contains electronic crossover, speakers sense, drivers protection, amplitude and phase response alignment circuitry optimised for the loudspeakers. The P113 or P212 SD controller's range allows the loudspeaker to be operated at full capacity with maximum fidelity and reliability. The trapezoidal shape of the cabinet allows cluster designs, enabling maximum mutual coupling and single-point source arrays.

(1) Frequency response: +/- 3dB, measured at 3 meters, on axis, half-space conditions -  MLSSA 1/3 octave

(2) Max peak SPL: Measured with music referred to 1 meter

(3) Crossover: Acoustical crossover frequency - at these frequency, transducers produce equal sound pressure level

(4) AES: Power handling is measured under AES standard conditions

(5) Power AMPS: Amplifier RMS output power per channel into 2 ohms, both channel driven
