Multiple power supplies
The ZRX-C30 receiver supports three types of powering. With the DC 9 V battery, the receiver can be used as a portable device for up to 3.5 hours, free from an AC adaptor cord and maximizing layout flexibility. Also, using this battery provides a simple solution for eliminating noise pick-up caused by the power supplies. For long-duration use, the receiver can be powered with the supplied AC 12 V adaptor, or the DC 9 V jack (for use with a power distributor).
