NE OF THE FIFTH ESTATE New Velocity "Mike" (Continued from page 25) ly both in front and in back of this microphone. Thus it may be used to pick up programs in which twice as many artists participate. The ratio of the space available as compared to that formerly available is in fact that more than two to one for artists may be placed further away from the microphone and also — since the directional characteristic does not discriminate against any frequencies — they may be placed far around to the side by properly considering the attenuation at such angles. This two-directional effect also allows an announcer or orchestra leader to speak into the microphone without interposing himself between the microphone and the orchestra. The Velocity Microphone does not require a built-in or closely linked amplifier. Its output may be fed to an amplifier located several hundred feet away in the control room. Moreover, mixing of the outputs of these microphones is entirely practical. Such a lowlevel switching arrangement reduces the number of amplifiers required with consequent economies in speech input cost. Since it requires no field or polarizing supply, the connections from microphone to control room are extremely simple — only a two-wire cable being required. The unit itself is relatively light. It may be quickly and easily removed from the stand and carried to another position. As the unit has mounted on it a receptacle into which the cable plug fits, it is unnecessary to drag the cable around with the unit. The Velocity Microphone is a radically new kind of microphone entirely different in principle and construction from all previous types. The improvements in studio pick-up which it makes possible, its increased fidelity, and the convenience with which it may be used seem to justify the assertion that it will soon replace former types of microphones in all progressive broadcast stations. Radio and Movies AS A FIRST step in his program of bringing radio and movies into closer alignment, M. H. Aylesworth, president of NBC and RKO, has arranged for a new RKO series over the NBC-WEAF network, "The Phantom of Crestwood," starting Friday, Aug. 26, at 10:30 p. m., EDST. Program is a mystery serial soon to be produced by Radio Pictures, but first to be heard in a series of six weekly installments, culminating in 100 cash prizes totalling $6,000 offered the radio audience for the best solution. Radio in Porto Rico PORTO RICO, served by WKAQ, San Juan, now operating on 890 kc. but seeking a switch to 920 kc, has about 15,000 radio sets in use, reports J. R. McKey, U. S. Trade Commissioner at San Juan, to the Department of Commerce. The population of this American territory is given in the 1930 census as 1,543,193. Station WKAQ, first in the Caribbean area, is installing modern new equipment.
