Sennheiser AC 3200-II Active High-Power 8:1 Antenna Combiner

Active 8-to-1 antenna combiner for multi-transmitter IEM and wireless systems up to 250 mW

The Sennheiser AC 3200-II is an active high-power 8:1 antenna combiner that routes up to eight wireless transmitter outputs through a single antenna. Designed for in-ear monitoring (IEM) systems and wireless audio link transmitters, the AC 3200-II eliminates the need for individual antennas on each transmitter, consolidating the RF output of up to eight channels into one shared antenna connection for cleaner rack organization and more predictable antenna radiation patterns.

With a maximum input power of 250 mW per channel, the AC 3200-II handles the output levels of professional IEM transmitters without signal compression or intermodulation degradation. The active combining circuit maintains signal isolation between channels, preventing one transmitter's output from interfering with another. The 1 RU chassis fits standard equipment racks, and an inline power supply is included.

Key Features

• 8:1 active antenna combining for up to eight transmitters
• Maximum 250 mW input power per channel
• BNC connections for all inputs and the combined output
• Active isolation between channels prevents inter-channel interference
• 1 RU rack-mount chassis for standard equipment racks
• Inline power supply included

Professional Applications

Commonly deployed in church, house of worship, and professional AV environments.

• Multi-channel in-ear monitoring systems on touring stages
• Wireless audio link transmitter consolidation in broadcast facilities
• Festival and event IEM racks with limited antenna space
• Permanent installations requiring clean, consolidated antenna deployment

Frequently Asked Questions

Are BNC interconnect cables included?

No. BNC interconnect cables between the transmitters and the AC 3200-II are not included and must be purchased separately.

Can I combine wireless microphone receivers with the AC 3200-II?

The AC 3200-II is designed for transmitter combining, not receiver splitting. For receiver antenna distribution, use Sennheiser antenna splitters such as the ASA series.

Related Equipment and Workflow Compatibility

The AC 3200-II is designed for Sennheiser IEM transmitters including the SR 2050 and compatible models. It is commonly deployed alongside Sennheiser ASA antenna splitters and A 5000-CP directional antennas in large-scale wireless system racks.

Why Professionals Use This Type of Product

• Consolidates eight transmitter antennas into one clean output
• Active isolation prevents intermodulation between combined channels
• 250 mW capacity handles professional IEM transmitter power levels
• Simplifies rack layout and reduces antenna clutter on stage
