B-21S - Overview

For balanced or unbalanced, line level equipment such as AM/FM tuners, tape decks and CD players. The TOA B-21S Transformer isolation minimizes ground loop problems when connecting remote equipment. Allows remote control of input signal using an external potentiometer.

Notes:
For unbalanced sources, use a shielded, twisted pair and connect the output to Hot and Common (inner conductors). Connect the shield to Earth at the module and leave unterminated (floating) at the source.
You can also connect a switch between screw terminals #4 and #5 for remote on/off operation. Closing the switch turns the module OFF, opening the switch turns the module ON.

  • Features:

    • For Balanced Or Unbalanced Line Level Sources such as mixer outputs, signal processors and wireless microphone receivers.
    • Transformer Isolation (10 kΩ) minimizes ground loop problems when connecting remote equipment (greater than 15 feet).
    • Remote Volume Control by connecting an external 10 kΩ, linear-taper potentiometer to screw terminals #4 and #5. Note: Control line resistance greater than 200 Ω will prevent full attenuation (200 Ω = 3821 ft. of #24 AWG wire).
    • Tip! You can also connect a switch between screw terminals #4 and #5 for remote on/off operation. Closing the switch turns the module OFF, opening the switch turns the module ON.
    • Connector: screw terminal (B-21S).
