Abstract

Ses yayin cihazi, tek tek iletme araçlari olan çok sayida akustik transformatörlerin alansal olarak dagilimina sahiptir. Çok sayida ve herhangi bir tipte transformatörler kullanilabilir. Isletme sinyalleri, düzenek alani boyunca dagilimlarda transformatörlerden istenen sekilde yayilmis veya kismen seslendirilmis olan faz bakimindan farkli ses yayinlari üretirler. Isletme sinyali üretim araci, daha yüksek akustik frekans içerigine sahip faz degistirme islevini de kapsamakta olup ayrica daha düsük frekans içerigi için düzenegin alt alanlarindaki transformatörlerin en azindan bazilarinin faz içi faaliyeti için de islevseldir.
