  • Page 2 Installation The silver support bars are used to support two sensors under the middle and treble strings. The gold double support bar suspends the third sensor over the bass strings. Before installing any of the pickup strips, remove the tie wraps from the gray cables and smooth out, stretch and straighten the cables.
  • Page 3 between 1/8- 1/4 inch of clearance. The other two pickups can be further away. Next place the other two sensors on the silver underbars, the longest sensor on the longest bar. ( They will stick on quite firmly because of their magnetic nature.) These support bars rest on pedestals that are padded to prevent scratching the soundboard, and to minimize vibration to the sensors.
  • Page 4 After placing the middle pickup in place under the strings, it helps to use the screwdriver to tuck the gray wire from the highest pickup under the middle bracket to insure that it won’t curl up and touch the strings and cause buzzing noises. When removing these units from the piano it is perfectly okay to use the gray wires to pull them out of the piano.
  • Page 5 Control Box The control box is a passive unit. It does not require batteries, phantom power, or any other power source. This means it is compatible with sound systems worldwide, and requires no maintenance. The three knobs on the control box control the volume of the three sensors. To start with, they should all be turned to their full-volume (12 o'clock) position.

  • Page 6: Troubleshooting

    Troubleshooting As durable as the Helpinstill systems have proven to be over the years, any instrument can malfunction. Sensors It is important that care is taken not to puncture the outer plastic casing of the sensors.
