Description
Analogue Two-Channel True Diversity Broadband Receiver
The ACT 700 series is robust and can be used flexibly and professionally in a variety of applications. The bright color VFD (vacuum fluorescent display), unique in the industry, offers a wide viewing angle for the high-contrast and crystal-clear display of all parameters. With a further improved 3rd generation RF and IF circuitry, the receivers offer excellent and superior audio and radio quality.
Specifications
Features:
- EIA standard 1/2 19 “RU (ACT – 717B) & 19” RU (ACT-727B / 747B) robust, heat-dissipating metal housing with perfect shielding against interfering interference.
- UHF-PLL synthesizer with high stability and low side emissions.
- 3rd generation Mipro: Improved RF filter elements and circuits for lower sensitivity to interference signals and more interference-free channels.
- 104 preset channels in 10 groups together with the auto-scan function enable the quick search for interference-free channels.
- The world’s first ACT ™ (Automatic Channel Targeting) offers precise and fast frequency synchronization between the receiver and transmitter.
- True diversity antenna system for best reception quality.
- Dual squelch setting for NoiseLock and pilot tone. Transmitter can be switched on / off at any time without causing disturbing noises.
- 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.
- Setting the reception sensitivity via the interference warning display. Higher sensitivity for a wider reception area, lower sensitivity to reduce interference.
- The output signal can be tapped via 3 levels as a single or sum signal. The output level is matched to the sensitivity of the microphone capsule and ensures optimal performance.
- TNC antenna connections with 8V power supply (e.g. for optional boosters)
- PC control software for real-time control and monitoring.
- Internal switching power supply for a stable voltage supply of 100 ~ 240V AC.
