About the Sennheiser AD 3700
The AD 3700 is Sennheiser's flagship receive paddleA directional antenna (paddle, LPDA, helical) aimed at the stage — focuses coverage where the performers are and rejects RF from elsewhere.: a wideband directional antenna with the AB 3700 booster built into the housing, so long coax runs back to a Digital 6000 or 2000-series rack stop costing you signal. The four-position amplifier (bypass to +15 dB) exists to offset cable loss, with an LED that color-codes the current setting from across the stage. It draws bias power over the same BNCThe twist-lock coax connector used for word clock and antenna runs — it locks, so it can’t be pulled out mid-show. feed from the receiver or antenna distributionOne pair of antennas feeding many receivers through an amplified splitter — replaces the forest of whips and keeps RF levels consistent., keeping the remote end a single cable.

Too low and you’re hunting through hiss; too high and peaks clip. + selectable bypass/5/10/15 dB amplification. Powered by 9–15 V DC over the coax (100–160 mA) from EM 3731/3732, EM 2000/2050, EM 6000 receivers or ASA distribution. Receive only.
