The TSD-DA13 1x3 distribution amplifier is designed to provide clean, isolated signal distribution locally or to remote locations.The unit allows a balanced mic or line level source to be distributed to three isolated variable outputs making it a perfect solution for applications including convention centers, houses of worship, restaurants/sports bars and industrial facilities.A high quality, low noise mic pre-amp, defeatable 3dB low cut filter @ 125Hz and dual summing RCA line level inputs are included as part of the unit's input section.These features combined with the 3 mic/line level outputs allow for multiple configurations.Isolation between outputs prevents crosstalk, removes miss matched input impedance concerns and allows for adjustable levels on each connected device.All I/O (except the summing RCA inputs) is via Phoenix style connectors for installation convenience.
