Swarmer (Expander) built & tested

The Swarmer is an eight stage audio FX expansion board made exclusively for the HiveR BUZZ Pro Audio FX Development System.

When paired with the Queen Bee you get a total of ten possible audio FX stages. In addition to that, Swarmers can be linked together to add more stages if needed. Every additional Swarmer adds eight stages.

Each effect stage of the Swarmer has these features:
• Input impedance adjustment from 0 to 2M (with test pads for you to measure added input impedance once your design is the way you want it)
• Effect Bypass
• Post EFX Return (bypasses all effects after the current one)
• Test loop on the effect out (used to extract the signal for later use, such as to blend the signal a few stages down. Example, dry signal blending into a wet chorus)
• 5v, 9v, 12v always available from the attached Queen Bee (Swarmer routes power, but does not supply it)
• Switch selectable -5v, -9v, -12v, or 15v-20v passed from the attached Queen Bee (Swarmer routes power, but does not supply it)
*The expansion header can be used as an additional effect stage but does not have the impedance adjustments, bypassing switches, or Audio Test features of the effect stages.
