Henry Engineering BackUPS Power Switcher

WorldCast Systems SynchroStream Technology WorldCast Systems has launched its SynchroStream technology for the APT codec range with the release of SR 4.0. The company states that with the release of SynchroStream they will become the only manufacturer to offer a one-stop shop for single-frequency network deployment with the transport (APT codecs), transmission (Ecreso transmitter), measurement (Audemat FMMC5) and monitoring (Kybio Software) available from WorldCast. The SynchroStream technology and the support legs approach benefits the broadcaster in simplifying the setup, configuration and maintenance of a solid and stable SFN network. SynchroStream is compatible with baseband audio coding and the existing MPX/composite linear coding schemes and also the new APTmpX algorithm, “the first nondestructive MPX/composite algorithm,” also part of the new SR 4.0. SynchroStream is supplied on the existing APT IP Codec range and utilizes an externally supplied 10 MHz clock and the 1 pps GPS signal as time reference. The company says beta network deployments in New Zealand and the United States have verified bench test results which calculated that the granularity offered in allowing fixed line adjustments down to an eighth of a microsecond (125 nanoseconds) would allow the highly accurate (<50 meters) manipulation of the “mush zone.” According to WorldCast, in the real world this means engineers can push the almost nonexistent mush zone away from populated areas or transport corridors. This manipulation translates to better coverage within the SFN FM area, consisting of main FM transmitter and FM boosters, meaning potentially more listeners for a station. Info:

Henry Engineering’s BackUPS is a power controller for ensuring reliable AC power to critical equipment. It is powered with an uninterruptible power supply (UPS). BackUPS constantly monitors the output of the UPS and automatically bypasses it if the output fails or becomes unstable. This keeps the load powered and allows the UPS to be disconnected for battery replacement or other maintenance. A restart-delay timer ensures the output is stable before the UPS is switched back online. Whenever the output comes on, the system monitors its output for a preset period. The UPS will be switched online only if the output is stable during this delay interval, which can be set from 10 seconds to 16 minutes and can be defeated if not needed. BackUPS is automatic once installed. The mode switch can select manual UPS bypass mode, or automatic operation with or without restart-delay. It can be monitored and controlled remotely. The remote bypass input allows the unit to “force bypass” a troublesome UPS via GPI control. BackUPS can also be used to reset and reboot equipment via off/on power cycling. It can supply up to 15 amps of AC current to the load. BackUPS can also be used as a “remote reboot” device, to reset and reboot equipment via off/on power cycling. It can supply up to 15 amps of AC current to the load. Info: | March 2021
