Universal Audio Attenuator

 

  • Audio Level Attenuation
  • Adjust Audio Level into Equipment
  • Preset Audio Levels
  • Precisely Match Audio Levels
  • Increase Audio Input Headroom
  • Two Adjustable Attenuators in One Package

APPLICATION: The STP-1 is a pair of convenient attenuator pads that can be located at the precise location that attenuation is needed. The low-cost STP-1 eliminates the costly labor of figuring and assembling fixed pads. Multi-turn trimmers in the STP-1 permit precise adjustment of levels without the need to connect any jumpers or external resistors.

The STP-1 operates in either high or low impedance, balanced or unbalanced circuits.

The wiring legend is printed on the case for easy installation.
