GX-4: High-Power RF Signal Management for IEM Systems

The Professional Wireless Systems GX-4 Combiner is an advanced RF IEM transmitter combiner and booster. Designed for compatibility with Garwood, Shure, or Sennheiser IEM transmitters. The GX-4 efficiently handles RF signals across the 470MHz – 698MHz frequency range. Each input features its own RF amplifier and Automatic Level Control (ALC) circuits. This ensures that signals are amplified to the optimal power level. Resulting in 250 mW of RF output at the antenna port, providing consistent performance for your wireless in-ear monitor systems.

Versatile Power and Connectivity

The GX-4 is also equipped with four RF inputs that accept input power levels ranging from 20 to 100 mW. It offers a single RF output and supports power modes that allow for selectable output levels of either 25 mW or 250 mW. This flexibility ensures that your IEM transmitters operate efficiently in various environments. The system also includes DC outputs compatible with Shure PSM, Sennheiser Evolution, and AKG IVM4500 transmitters, making it a versatile choice for professional audio setups.

Rugged Build and Reliable Power Supply

The GX-4 is built for durability, with robust connectors and a reliable 12 Volt, 4 Amp DC power supply. It supports AC power requirements of 100 – 240 VAC at 1.4 amps, ensuring that it can operate in diverse power conditions. Whether you’re working in a studio, on a stage, or in a broadcasting environment, the GX-4 delivers the reliable performance you need for seamless audio transmission.

PS - This unit is NOT 21 lbs - the GX data sheet has that number for the GX-8. Shipping weight for the box is around 12 lbs.
