AC224 Overview
The AC224 is a 2×2 IN and 2×4 OUT active antenna combiner and distribution system with in-built front-end low-loss band-pass filtering, LNA, and user-adjustable gain stage at each antenna input. The AC224 enables the user to cover a wider area with 2-zones, for cart and trolley set-up applications with improved RF coverage and performance. Provides a tidy solution in sound bag applications as a 2×1 IN and 2×4 OUT.
There are four industry standard BNC Antenna input connectors that enable use of standard low loss RF extension cables, and there are eight mini-RF SMA connectors feeding the diversity receivers. Each antenna input can be individually turned ON/OFF via the display menu when not used, with an LED indicator showing the status of each Antenna input.
In applications when remote antenna powering is needed, the AC224 offers individually switchable Remote Antenna powering, with LEDs indicating power status. The Active Antenna Powering can be turned ON/OFF through the display menu.
The AC224 has a very high input signal handling capacity with very low noise figure and offers an outstanding inter-modulation performance when compared to other available low-power devices.
The frequency range is custom tuned to customer’s order. The front-end band-pass-filter design is a very low-loss with a very high selectivity at lower and upper frequencies; each antenna input gain is individually user adjustable in 1dB steps between +6dB to -10dB. The AC224 is compatible with full-digital, digital-hybrid, and analogue radio microphone receivers available in the industry.
A large color TFT display offers user selectable color combinations to suit lighting and visibility. Brightness may be adjusted through the display menu for better visibility.
The AC224 is externally powered between 10-18V DC. The DC input is an industry standard 4-pin Hirose, and the DC Distribution with 4xHirose DC output connectors for powering auxiliary equipment. Each DC output port can be individually turned ON/OFF through the display menu. A voltmeter continuously monitors the DC input voltage.
Audio Wireless wide tuning range systems are now first choice among freelance sound engineers and major broadcasters, for all wireless microphone applications.
