Description

Overview

The AC224 is a two-zone combiner, RF, and DC distribution system designed to fit in a sound bag without sacrificing performance.

It features a 2x2 IN and 2x4 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 wide two-zone area for cart and trolley set-up applications with improved RF coverage and performance and provides a tidy solution in sound bag
applications as a 2x1 IN and 2x4 OUT.

There are four industry standard BNC Antenna input connectors for low loss RF extension cables and eight mini-RF SMA connectors feeding the diversity receivers. Each antenna input can be individually turned ON/OFF via the display menu when not use;, a LED indicator shows 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 a very low noise figure and offers an outstanding inter-modulation performance at its power level.

The front-end band-pass filter design is a very low-loss with 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 analog radio microphone receivers.

A large color TFT display offers selectable brightness and color combinations to suit the lighting and visibility.

The AC224 is externally powered between 10-18V. The DC input is an industry standard 4-pin Hirose and distribution is accomplished via four Hirose DC output connectors for powering auxiliary equipment. Each DC output port can be individually turned ON/OFF through the display menu and a voltmeter continuously monitors the DC input voltage.
