Whirlwind Selector A/B Pedal

The famous Whirlwind Selector is the only A/B A+B box that provides totally noiseless switching between channels. It can be used either as a 1 -in 2-out device or as a 2-in 1out device. Whichever way you use it, the Selector is the best channel-switching device your money can buy. The Selector can be powered by either a 9-volt battery or DC adapter (Whirlwind accessory T401-ND, not included). To insert a battery, simply remove the 4 screws from the bottom of the unit and clip a 9-volt alkaline type battery to the battery clip. Replace the bottom and screws. On The Selector are three 1/4" jacks, one 1/8" jack, two LEDs and two foot-switches as outlined below:

• I/O PORT
  A 1/4" jack that should be used for input from a musical instrument when the unit is being used as a 1 -in, 2-out device, or as an output to an amplifier when the unit is being used as a 2-in, 1 -out device.
• A and B
  1/4" jacks that should be used as outputs to an amplifier when the unit is being used as a 1-in, 2-out device or as inputs from musical instruments when the unit is being used as a 2-in, 1 -out device. A/B (Button) When pressed, toggles the I/O port between "A" and "B"
• BOTH (Button)
  When pressed, engages the A and B channels simultaneously. When pressed again the selection returns to the channel which was previously selected.
• LEDs
  Indicates which jack is selected for output or input. Both LEDs illuminate when the BOTH feature is engaged.
