EARTH LOOP-GROUND HUM ELIMINATOR
The B.I.S Box Earth Loop Hum Eliminator is used for removing hum caused by earth/ground loops. If using two amplifiers, simply connect one amp to the buffered output and the other amp to the isolated output and this will stop the hum (the B.I.S Box will only stop earth loop hum, not hum picked up by your guitar). Used by top touring bands around the world.
The B.I.S Box is used for:
Features - 9V battery operation with "4 hours to go" indicator - so you know you can finish the gig!! The B.I.S. box is also NOT sensitive to hum fields, i.e. power transformers in guitar amps.
INPUT - Guitar or line level J.Fet input. High impedance
OUTPUT BUFFERED - Unity gain. Low impedance
OUTPUT ISOLATED - Unity gain. Low impedance. Floating earth
POWER 9v PP3 Battery
