Atlas Sound introduces the TSD-DA13 is a 1x3 distribution amplifier that distributes balanced mic or line-level sources to three isolated variable outputs. This high-quality distribution amp features a defeatable 3dB low cut filter at 125Hz. It also features a dual-summing RCA line level input as well as 3 mic/line level outputs. 

The TSD-DA13 features isolated outputs, which prevent cross-talk and ensures that mismatched input impedance are resolved. This distribution amplifier requires a separately purchased power supply, however, multiple TSD units can be powered via a single power supply. The TSD requires 60mA of power. Other key features of the TSD-DA13 include the following:

  • Switchable 24V Phantom P=power
  • High gain (50dB), low noise mic preamp
  • Summed dual RCA input
  • 12dB/octave low cut filter @ 125Hz
  • High gain output for driving long balanced lines
