Polarità

WH20QTR cablato: una pressione positiva sul diaframma produce una tensione positiva sulla punta rispetto al manicotto (massa) del connettore a spina fono di uscita microfo- nica.

WH20QTR e WH20TQG usati con sistemi senza fili Shure:

Uscite fono tipo jack da 1/4" del ricevitore: una pressione positiva sul diaframma produ- ce una tensione positiva sulla punta del connettore di uscita del ricevitore.

Uscite XLR a tre piedini del ricevitore: una pressione positiva sul diaframma produce una tensione positiva sul piedino 2 rispetto al piedino 3 del connettore di uscita a bassa impedenza, e sulla punta del connettore di uscita ausiliaria (Aux).
