A superior cardioid directional pattern minimizes feedback, background noise, reverberation, offaxis coloration and placement problems. A new internal vibration isolation system, consisting of a special rubber mounting ring and a rubber stabilizing ring as a support for the generating element, reduces gooseneck, stand and handling noise. An effective multi-stage blast filter controls breath "pop" and wind disturbances. Available as a 119L (chrome), 119LB (black) and 119L-19 (as shown). The 119L Series has low impedance outputs. The 119L-19 is supplied with 1.7m (5.5ft), the 119L and 119LB with 2.1m (7ft) of rugged two conductor shielded cable. The 119 Series microphones are extremely rugged and reliable and will stand up under the most strenuous handling conditions to provide years of dependable service. ASTATIC Quality All 119 microphones are audio tested and inspected prior to shipment. Our absolute commitment to quality insures that ASTATIC microphones remain the Best Value in today's competitive industry.

SPECIFICATIONS FOR 119L / 119LB / 119L-19 Architects' and Engineers' Specification The microphone shall be an ASTATIC 119L, 119LB or 119L-19. The microphone shall be a dynamic moving coil type with a diaphragm made of polyester. The frequency response shall be 80 Hz to 15 KHz. The microphone shall have a cardioid polar pattern. The output level of the 119L Series (500 ohms) shall be -60 dB (0 dB = 1 mW/10 microbar); -77 dB (0 dB = 1 volt/microbar); 1.4 mV/Pa. The microphone will feature an internal shock mounted element to reduce gooseneck and handling noise. The microphone will be wired for balanced line operation. The microphone will have a zinc die cast and brass housing and be finished in satin chrome (119L), and black (119LB). The 119L-19 microphone will be fitted with a 508mm (20") chrome flexible gooseneck and mounting flange. The 119L and 119LB shall have a permanently attached 2.1 M (7ft) two conductor overall shielded synthetic jacketed cable. The 119L-19 shall have a permanently attached 1.7M (5 1/2') two conductor overall shielded sy...
