subject: Audio Performance With SLIC [print this page] Ringing has been shown to perform well under 5-REN loading. The ac portion of the ringing produced after this modification is the same ac portion of the ringing produced before. Because the dc power is not absorbed by ringers, the ringing power delivered to the load is the same. However, the peak voltage provided to the load is increased by the value of the dc offset. It is possible to increase the ac ringing voltage from 65 to 100 Vrms. If this is done, more power will be dissipated on the transistors, and they must be scaled to accommodate this.
