What is it? A true digital wireless system incorporating both single and dual-channel receivers and bodypack and handheld transmitters. Details ￼ Both the ACT-818/828 (single-channel) and ACT-828 (dual-channel) models are true diversity digital receivers with no companding circuitry and said to be free from the sonic artefacts inherent in other wireless systems. The receivers employ 256-bit encryption that can be enabled/disabled as required and operate from 480MHz to 698MHz over three bands, each covering an expanded 64MHz bandwidth. Offering true digital operation, the receivers employ 24-bit /44.1kHz audio sampling, 115dBA dynamic range, SmartEQTM with capsule emulation and low-latency operation for use in live sound, broadcast, corporate, education and house of worship applications. The ACT-80T digital encryptable bodypack transmitter is intended for applications requiring a head-worn or lapel microphone and is said to be the world's smallest true digital bodypack unit. In addition to direct mute capability, the ACT-80T offers remote muting via the optional MJ-70 remote switch and a battery life of over 12 hours from two AA cells. The transmitter is housed in a robust magnesium alloy case with onboard multifunction backlit LCD display, shielded controls (to prevent accidental operation) and six selectable gain settings. Also built into a magnesium alloy housing with an LCD display, the ACT-80H handheld microphone transmitter incorporates a true condenser cardioid capsule said to offer enhanced audio quality and superior off-axis and plosive characteristics. And another thing… In addition to manual mute, an auto-mute function (which automatically mutes the transmitter when it is lowered to the user's side) is included as a means of avoiding feedback.
