The STM-DA3 from RDL is a compact and portable microphone distribution amplifier designed for use in broadcast and recording applications. Part of RDL's "stick-on" series, the STM-DA3 is perfect for use in a studio or out in the field and comes with adhesive for permanent or removable mounting. Built on the electrical architecture of RDL's mic preamps, the STM-DA3 provides excellent audio quality with very low self-noise, suitable for any professional application.
Featuring a 1.2 k ohm balanced input, the STM-DA3 accepts a wide variety of mic input levels without loading low-impedance microphones. Phantom power can be supplied when the supply voltage is connected to the "PHM" screw terminal. A multi-turn trimmer allows you to adjust the gain to match microphone levels.
The three balanced outputs provide full audio isolation. A dual LED VU meter shows green over a 15dB range and goes to red when the optimum operating level is exceeded. These professional features tucked neatly into such a portable package make the STM-DA3 a must when you need to feed one microphone into 3 mic inputs.
