RDL STM-DA3 Microphone Level Distribution Amplifier 1x3

Microphone Level Distribution Amplifier - 1x3 The STM-DA3 is designed for use in quality commercial sound, broadcast and recording applications. The 1.2 kΩ balanced input accepts a wide variety of microphone input levels without loading professional low impedance microphones. A multi-turn trimmer is user adjustable for either gain or loss in order to match the facility standard microphone levels. Three balanced outputs provide nearly total isolation between the output lines. Unlike mic-splitting transformer systems, the STM-DA3 also provides audio isolation. In fact, the audio isolation is so good that a +4 dBu signal fed into one output is still below the noise floor on the adjacent output. Loading of one output including a direct short, has no effect on the other outputs. The STM-DA3 is built on the electrical architecture of RDL's low-noise studio quality mic preamplifiers. Dynamic or condenser microphones may be used with the STM-DA3. Standard 24 V phantom is supplied to the input
