Eigenschappen
The ACT-828 is an EIA standard 1U dual channel receiver with metal chassis.
A full-color VFD (vacuum fluorescent display) provides clear viewing of all parameters. All controls are intuitive and easily accessible, allowing for quick and easy system setup via a single rotary control.
Enhanced RF circuitry improves anti-interference characteristics and system compatibility with a 64 MHz-wide bandwidth, allowing more interference-free channels to be selected.
New digital diversity receiving technology eliminates signal dropout and enhances receiving range.
Full-range sound quality is not affected by the strength of RF signals or operating distance.
Digitally-processed RF circuitry and DigitnamicPlus™ technology eliminates compander noise, assuring a wireless sound quality that easily rivals cable transmission.
Improved proprietary Audio A/D Converter provides a true dynamic range of 115 dBA, T.H.D. < 0.03% at 1 kHz with < 2.7 ms latency.
AES3id Digital Audio Interface facilitates a direct connection to digital mixing consoles and transmits signal without distortion, ensuring a stable S/N ratio which will not deteriorate in long distance transmission.
Proprietary 256-bit encryption provides secure audio transmission, preventing unauthorized listening.
10 built-in SmartEQ™ presets and user-defined microphone capsule equalization allows faithful sound reproduction to suit artists’ preferences.
10 built-in digital anti-feedback SmartEQ™ presets minimize feedback effectively without sacrificing sound quality.
Optional MIPRO RCS2.Net software allows real-time network remote-controlling and monitoring of 64 systems.
