RDL STM-2 Adjustable Gain Microphone Preamplifier - 35 To 65 dB Gain

the STM too is a low-noise cost-effective microphone preamplifier that boosts the signal from a dynamic or condenser microphone up to line level gain is adjustable from 35 to 65 DB the module has two identical line level outputs that can feed two different equipment line inputs or one stereo line level equipment input the STM two input and each output may be connected balanced for professional equipment or unbalanced for consumer products the input is usually connected balanced during installation connection of a single jumper activates phantom voltage for powering a condenser microphone the module supplies an IEC standard p24 phantom voltage that powers all compliant microphones specified for 24 volt phantom operation and most mics accepting 48 volt phantom gain is also set during installation to provide the desired output level typically minus 10 DB v if the module outputs are connect
