Control 47HC menampilkan pola cakupan sempit 75° yang ideal untuk digunakan di ruang yang sangat bergema dan aplikasi plafon tinggi. Pola tersegmentasi ini membantu meminimalkan suara yang memantul dari permukaan ruangan serta anomali kedatangan waktu dari loudspeaker berdampingan, sehingga meningkatkan kejelasan ucapan. Control 47HC menampilkan karakter sonik yang sama seperti Control 47C/T dan ideal untuk pusat transit ramai atau ruang pusat konvensi besar.
