Whirlwind SB Series 24-Channel Passive Mic Splitter | SB24P1G

The Whirlwind SB24P1G is a passive 24-channel microphone splitter designed for live sound engineers, touring production crews, and install integrators who need to route a full stage's worth of mic signals to two separate destinations simultaneously — such as front-of-house and a monitor console, or a recording interface and a broadcast feed. Because it operates passively, there are no power requirements or active components to introduce noise or failure points, making it a dependable choice in demanding production environments.

Each of the 24 channels receives a single mic-level signal through a Whirlwind WC3F female XLR input and distributes it to two male XLR outputs. This architecture keeps signal paths clean and predictable, which is critical when splitting to consoles with differing grounding schemes or input sensitivities. The SB series represents Whirlwind's professional-grade approach to passive splitting, built for rigs where reliability and signal integrity are non-negotiable.

Compared to active splitters or patchbay-based workarounds, the SB24P1G offers a straightforward, low-maintenance solution that experienced engineers trust precisely because there is nothing to power up, calibrate, or replace between shows. It belongs in any touring system, theater install, or broadcast stage setup where a full 24-channel passive split is needed.
