Get to know them!

Set off a whirlwind of switching activity with the Whirlwind AB-8. This 8-channel bidirectional switcher for mic, line, and MIDI signals can be configured individually or assigned to a master control, which is controllable via its front panel or an optional footswitch. Each channel is configurable as a one-in/two-out, a two-out/one-in, or a mixture of both, and the front panel indicator lights make it easy to see the status of each channel. It’s also easy to chain multiple units with the master control or using the Control Voltage input. The AB-8 also features an auto-switch function that can be a lifesaver during live performances. It automatically switches to redundant copies of backing tracks, enabling seamless live performance even when there’s a temporary signal loss. The Whirlwind AB-8 is also a useful tool for studio engineers, with the ability to switch back and forth between tracking and mixing setups effortlessly. Sweetwater studio and live sound engineers agree: the AB-8’s ease of use and smart redundancy capabilities will greatly improve (and potentially save) your live performances and tracking sessions.

Whirlwind AB-8 8-channel Switcher Features:

  • 8 channels of balanced A/B switching for line, mic, or MIDI signals that can be switched individually or assigned to a Master Control
  • Use front-panel pushbuttons or an optional footswitch to control master switching
  • Master switching is also automatically triggered by losing signal on channel 1 of input A
  • Configurable as 1 input to 2 outputs, 2 inputs to 1 output, or a mix of both
  • Several units can be chained together using either Master Control or Control Voltage input
  • Easily see the status of each channel with indicator lights
  • In recording situations, you can easily switch from tracking to mixing and vice versa
  • During live performances, auto-switch function automatically switches to redundant copies of backing tracks for seamless performances
  • Auto-switch can accommodate input signal levels from -20dB to +20dB thanks to its sensitivity and hold time controls
  • When AC power is removed, all signal paths revert A to Common
  • DC voltage blocking requirements and ground path switching are configured by internal DIP switches

These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
