Electro-Voice RE3-ACC-AASP - 2-in × 8-out active antenna distributor (470–960 MHz) for diversity wireless systems

The Electro-Voice RE3-ACC-AASP is an active antenna distributor that acts as an RF and DC power distribution center in multi-channel systems. It divides each input antenna (A/B) into four outputs per side to feed up to four diversity receivers without loss of level, thanks to its 3 dB (±2 dB) RF output gain . It also incorporates cascade outputs per antenna (level 0 to +2 dB) that allow distributors to be chained without sacrificing any of the 4 outputs per side: up to five AASPs can be cascaded from a single pair of antennas.

The AASP distributes +12 VDC power to four receivers and provides power for active antennas and/or boosters over the coaxial cable (selectable). It is factory -activated ; if necessary, deactivation is via a switch located on the main board inside the chassis. It operates in the wide 470–960 MHz range, with 25 dB isolation between outputs to minimize crosstalk and standard 50 Ω BNC connectivity , allowing it to work with passive (e.g., half-wave ) or active antennas and in-line boosters.

Main features

• 2-in × 8-out architecture : two antenna inputs (A/B) to 4 RF outputs per side for diversity receivers.
• RF output gain 3 dB (±2 dB) to compensate for splitting; cascade output 0 to +2 dB per antenna.
• Built-in DC power supply : +12 V/1 A × 4 for receivers; booster feed +12 V for antennas/boosters (ON by default, with internal switch ).
• Wide working range : 470–960 MHz ; impedance 50 Ω; isolation between outputs 25 dB.
• Lossless Cascade : Chain up to 5 AASPs from a pair of antennas while maintaining all 4 outputs per side.
• 1U (half rack unit shallow depth) construction , black polyurethane paint finish.

Product benefits

• Stable and tidy multi-channel systems : a single pair of antennas for several receivers with good RF margin.
• Fewer sources and cables : +12 V DC distribution to receivers and coaxial power supply to antennas/boosters.
• True scalability : dedicated cascading outputs to grow without giving up output sockets.
• Wide compatibility : works with passive (including 1/2 wave) and active/booster antennas on 470–960 MHz .

Use cases

• Theaters and corporate events with multiple microphone links or wireless instruments.
• Touring racks requiring remote antennas, boosters, and simplified power distribution.
• Fixed installations where several distributors need to be connected without losing outputs.

Frequently Asked Questions

• Is the power supply for active antennas/boosters enabled? Yes, it's ON by default; it can be disabled using an internal switch on the board.
• How many distributors can I connect? Up to 5 units from a pair of antennas, maintaining 4 outputs per side.
• What connectors does it use? 50 Ω RF connectivity with standard BNC connections .
