Whirlwind SP1X3LL Line-Level Splitter
The Whirlwind SP1X3LL line-level splitter feeds one source to three destinations, through one direct output and two transformer-isolated outputs.
The signal at each isolated output runs 6 dB below the level of the direct output, and each isolated output has its own ground lift switch. The input takes up to +20 dBu at 20 Hz. For microphone-level signals, Whirlwind makes the SP1X3.
Features
- One line-level input, three outputs
- Two transformer-isolated outputs, 6 dB below the direct output
- Individual ground lift switch on each isolated output
About Whirlwind
Whirlwind began in 1975 and is based in Rochester, New York. They build audio interface gear in the USA, from direct boxes, splitters, and testers to snakes and power distribution. Each cable is built by hand, one at a time, and their own metal shop punches and engraves custom panels.
