Speakers at Athletic Park -Rebroadcast First Test

EOAUSH of receivers and power amplifiers at Athletic Park, Wellington, on the occasion of the first Test, visitors were able to hear the broadcast of the first Test with Britain. — _ A deputation representing the Radio Section of the Electrical Federation waited upon the Rugby Union, and were successful in arranging for the installation of suitable . loudspeakers al Athletic Park. It was decided that three Atwater Kent radio sets should be used, one being located close to the score board so that the scores could be posted within seconds of the actual happening in. Dunedin, and the second at the northern corner of the north-, west bank. For the grandstand patrons it was realised that something more powerful was necessary--the staiid was comparatively shallow and very long, the seating capacity being 4600. Constructed entirely of concrete and steel, its acoustic properties were about as poor as possible. It was also desired to minimise the volume of sound reaching the actual playing area. The rectified output of the anode

bend detector was led by means of resistance coupling to the public address amplifier. This amplifier has three stages com-~ pletely A,C. operated, the output valve being a 50-watt type specially designed for this amplifier. HERE was «a considerable amount of landline hum at times, but considering the nature of the landlines between Christchurch and Dunedin, the effort all round was good. It was much appreciated by the public at ‘Athletic Park, who, though watching the Varsity-Marist game, proved by their instant appreciation of any test match happenings that they were listening as intently as-they were watching. Prior to and subsequent to the Test match, the crowd was treated to gramophone record renderings through 4 pick-up, and the amplifier, and these, not being subject to the little imperfec: tions unavoidably associated with 4 long distance relayed broadcast, gave the public a truer indication of the capabilities of the whole installation.
