Wideband Digital Receivers Wideband Digital Receivers MIPRO'S Proprietary "ACT" Function and Operation Setting ACT Transmitter Frequency What is ACT? Press ACT button “ACT” stands for “Automatic Channel Targeting”. MIPRO developed and patented this innovative InfraRed (IR) technology in 2001. MIPRO was the first manufacturer in the industry to automatically synchronise the frequency selected on the receiver to any ACT handheld or bodypack transmitter in the same frequency band.
Wideband Digital Receivers Wideband Digital Receivers Computer Network Interface Operation BA: Transmitter Battery Meter (receiver display) 1. MIPRO ACT receivers are fitted with an ACT-BUS interface to enable remote control and monitoring via a PC-based control system. To enable this to communicate, an optional MIPRO interface adapter and software package is required. 2.
Wideband Digital Receivers Wideband Digital Receivers Troubleshooting General Tips for Improving System Performance ! Since the installation of the antenna influences the operating efficiency of the receiver, the most important rule is to minimise the distance as much as possible between the receiving antenna and the microphone for the best reception and performance. Symptom Solutions No Sound ! Power-on receiver & transmitter. ! Use MIPRO supplied antennas to ensure proper receiver sensitivity.
Wideband Digital Receivers Wideband Digital Receivers Troubleshooting Symptom Solutions RF Interference ! Press AutoScan button to locate a clear, interference-free channel. ! Use preset compatible channels in the same group when operating multiple systems. ! Place receivers away or remove the sources of RF interference like solid metal objects, electronic equipment & digital devices, dimmers, effect equipment, motors. ! Avoid operating a frequency on a local TV channel.
