Description
Digital two-channel true diversity broadband receiver
MIPRO’s new digital wireless systems of the ACT-800 series have an excellent sound quality that can compete with any wired microphone. With up to 216 pre-programmed channels plus 16 freely programmable channels, the receivers ACT-818, ACT-828 and ACT-848 with 64 MHz bandwidth ensure optimum flexibility even for larger setups. The digital signal means that the audio quality of the system is independent of the transmission distance and the transmission power. The digitization (24-bit / 44.1kHz) is higher than that of a CD. A digital 256-bit key ensures tap-proof radio transmission. Via a digital AES EBU interface, the signal can be transmitted over a long distance without cables (e.g. to a digital mixer). The ACT-828DNT model variant of the four-channel receiver is additionally equipped with a Dante ™ interface. The handheld transmitter is equipped with a real condenser head as standard, which delivers an exceptionally clear and precise sound. Thanks to the innovative interchangeable head system, it can be exchanged quickly and easily with a dynamic head. All in all, the ACT-800 series offers crystal clear sound for the highest demands at an affordable price.
Specifications
- Robust metal housing EIA standard 1/2 19 “” RU.
- The bright color VFD (vacuum fluorescent display), unique in the industry, offers a wide viewing angle on the crystal-clear display of all parameters. Automatic dimming of the display in standby mode.
- All settings can be made intuitively and quickly using a single rotary knob.
- Improved RF filter elements and circuitry for less sensitivity to noise. 216 pre-programmed interference-free channels plus 16 freely programmable channels.
- The new digital diversity receiver technology prevents dropouts and increases the reception area. A constant digital transmission does not result in any signal-related attenuation.
- DigitnamicPlus ™ technology eliminates any compression noise.
- The unique audio A / D converter delivers a dynamic range of 115dBA, works with a latency of less than 2.7 ms and eliminates saturation or distortion at high frequencies at high levels.
- The Digital Audio Interface (SPDIF) enables direct connection to digital mixing consoles and sends signals without distortion, ensuring a stable signal-to-noise ratio, even when transmitted over long distances.
- The unique 256-bit encryption guarantees secure signal transmission and protects against unauthorized listeners.
- The built-in SmartEQ ™ provides extensive setting options, as well as 10 user presets to simulate different microphone capsules – so every artist can choose his preferred microphone
- PC control software for real-time control and monitoring of up to 64 receivers.
- Receiver supplies supply voltage for optional antenna systems / boosters to expand the reception range and increase reception stability.
- The world’s first ACT ™ (Automatic Channel Targeting) offers precise and fast frequency synchronization between the receiver and transmitter.
