Whirlwind SB Series multichannel microphone splitters provide a convenient method of splitting multiple microphone signals to two locations.
Each channel has a Whirlwind WC3FQ female XLR input connector wired to two Whirlwind WC3MQ male XLR outputs - available with either two direct outputs or one direct and one transformer isolated output. These can be ordered with ground lift switches on one output.
The boxes are built from heavy cold-rolled steel for long term abuse-resistance.
