COMBINE4 Transmitter Combiner
The RF Venue COMBINE4 is an active 4-channel IEM transmitter combiner engineered to bring together up to four in-ear monitor transmitter signals into a single, unified transmit antenna. By consolidating multi-transmitter setups, it effectively eliminates the clutter and phase issues caused by multiple directional antennas while significantly lowering the buildup of unwanted intermodulation distortion (IMD) for cleaner, more reliable wireless monitoring.
Key Features
- Consolidated IEM Transmission: Actively combines up to 4 wireless IEM transmitters into a single, high-performance antenna output to clean up your RF workspace.
- Intermodulation Reduction: Specifically designed to lower intermodulation buildup, safeguarding your wireless environment from harmful multi-transmitter interference and sideband noise.
- Centralized DC Power: Features 4 dedicated DC power outputs providing up to 12V 1A each (48W total) to power connected transmitters directly and streamline rack cable management.
- Signal Threshold Monitoring: Equipped with front-panel LED indicators that clearly show input signal status when levels exceed the +5 dBm threshold power.
- Rugged 1-RU Enclosure: Built into a durable, all-metal 19-inch rackmount chassis perfect for demanding touring rigs or permanent commercial sound installations.
