Iconoclast does not have an explicit hardware bypass switch. However, you have three options for bypassing Iconoclast:

  1. Obviously, you may simply remove it from the signal chain. 
  2. Use a Y-cable, such as a Hosa YPP-106, on Iconoclast's input to create a "thru" output. Iconoclast's very high input impedance allows this without degrading the signal quality.
  3. Use Iconoclast Software to engage the "Digital Bypass": go to the Output tab > Master Output section > click the Enabled knob.
