LD Systems Stinger MON121AG2 The LD Stinger MON121AG2 is a compact active stage monitor for all mobile applications. The specially developed 12" coaxial speaker with an integral 1" HF driver and powerful ferrite magnets stands out because of a precisely symmetrical dispersion over 75° x 75° and attains a maximum sound-level pressure of 124dB with maximum resistance to feedback. It is driven by a Class AB power amplifier with a power output of 1000W Peak. The frequency response curve is 80Hz - 20kHz. Dependable operation of the LD MON121AG2 is ensured by a limiter that prevents overloading of the speaker and a protection circuit that guards against short-circuiting. The input is a XLR-jack combo socket, an XLR output permits looping through of the signal. Other connector panel features include a volume control, IEC power socket, LED indicators of various colours for power, signal, and the limiter function. The elegant looking bass-reflex enclosure of the LD MON121AG2 is made of 15mm-thick multiplex finished with a durable coating. A sturdy metal grille guards against speaker damage, and ergonomically milled handles make transport easier. The monitor angle is 35°.
