Shotgun stereo microphone

Designed for stereo location reporting amid noisy surroundings, the Neumann RSM 19()i system comprises a shotgun stereo microphone with windscreen, a matrix amplifier, and all connecting cables.

Neumann says the system is also ideał for stereo television, where soloists can be accentuated with presence and mid-dle emphasis, while the orchestra can be picked up with a variable, wide bass width. Another application for the RSM 190i System is for live or dubbed stereo film sound.

Two closely spaced capsule Systems ensure particularly clean and coloura-tion-free reproduction. A transducer with a short interference tubę delivers the middle signal. The side signal is sup-plied by a second independent capsule system comprising two transducers with a figure-8 characteristic at right angles to the microphone axis.

The RSM 190i can be operated in a hand held position, attached to floor stands or booms. The system is stored in a robust, aluminium carrying case which can also accommodate a complete microphone mounted in a windshield, plus other equipment.

“Universal” remote control

The audio-visual age is upon us, and almost every new component that is produced has its own remote control unit. In response to the problem of the. inereasing number of separate units that are now necessary to operate today*s technology, Onkyo has developed the RC-AVIM Universal Remote Control, which enablcs the user to dispense with the clutter of key pads and operate up to six components from a single remote control.

The RC-AVIM can not only control any Onkyo remote controlled product, but can be programmed to imitate virtu-ally any components operated by infra-red remote control, from any manufac-turer. The RC-AVIM can learn the functions of as many units as its memory can storę (tuner amp, video disc player and video cassette recorder, for example). The RC-AVIM is the first unit of its kind and provides the key to a successful marriage of audio and

Australian designed monitor loudspeaker

Audiosound Laboratories has released the Prague 8045A, a high performance two-way medium size loudspeaker system designed for smali stu-dios, control rooms and situations where accuracy and moderately high power levels are required. It is also suit-able for high quality public address, and its slim depth facilitates wali mounting

or array stacking on a suspended platform.

The 8045A has close tonal balance to imported high cost studio monitors and for critical adjustment is fitted with 3dB switched attenuators for finał balance of the midrange and treble. For its size the 8045A offers very good Iow frequency performance as the redesigned vented enclosure now incorporates a vented magnet woofer with high temperaturę voice coils. Like all other Audiosound loudspeaker systems it is Computer cor-related to accepted Thiele/Small pa-rameters, these correlations being done in conjunction with Mr A N. Thiele himself. The bass response is -3dB at a Iow 42Hz (many loudspeakers quote their bass rolloff at -6dB).

The extensive crossover system uti-lizes uir-cored coils and polyester ca-pacitors with a modified third order (18dB)/octave) Butterworth filter feed-ing a high performance dome treble-unit. This gives much improved power handling and phasc performance com-pared with the normally used 12dB/oc-tave crossovers and ferrite or iron cores.

Efficiency is around 89dB/(l watt, l metre) and it is suitable for amplifiers from 10-100 watts. The rigid enclosure features a 25mm MDF baffle and back, with multiple front-to-rear and side-to-side bracing. The bass-unit mounts on 4 pillars which form part of this rigid system for Iow- sound colouration from the enclosure. Outside dimensions are 610 x 440 x 260mm (HxWxD).
