Audio Wireless AC224 2-Zone Antenna Combiner

The Audio Wireless AC224 is a 2-zone antenna combiner and distribution system that feeds up to four diversity receivers from four antennas and powers other gear from the same DC supply.

On a sound cart it works as a 2 × 2-in, 2 × 4-out system, so two pairs of antennas cover a wider two-zone area. In a sound bag it runs as a 2 × 1-in, 2 × 4-out system.

Each of the four BNC antenna inputs has its own low-loss band-pass filter, low-noise amplifier, and gain control, adjustable in 1 dB steps from +6 dB to -10 dB. The BNC inputs take standard low-loss RF extension cables, and eight SMA outputs feed the receivers. It works with full-digital, digital-hybrid, and analog radio mic receivers.

Each antenna input, its remote antenna powering, and each of the four Hirose DC outputs switch on and off from the color TFT display menu, and LEDs show the status of each input. The display’s brightness and colors are adjustable for the lighting.

The AC224 runs on 10 to 18 V DC through a 4-pin Hirose input, and a voltmeter monitors the input voltage. Its case is CNC-machined aluminum.
