Audio distribution amplifier allows bridging of any audio line, adjusting the gain (0~+20dB), and driving either high or low impedance, balanced or unbalanced loads.

Typical applications:

  • Audio distribution with up to 3 outputs
  • Bridging a line for local distribution
  • Distribution with impedance conversion
  • Distribution with gain or loss
  • Inputs and outputs RF bypassed
  • Power requirements: 24~30VDC floating or 12~15VDC bipolar supply, 50mA

  • Product Reviews

    • "Perfect for overflow situations" by precept on 3/24/2014
      Overall: 4.5 out of 5

      We use these to feed our bookstore and classrooms for overflow during on campus events. They work great but are susceptible to lightning strikes.
