Product description - RDL STM-DA3 Microphone Level Distribution Amplifier - 1x3
The STM-DA3 Microphone Level 1 x 3 Distribution Amplifier from RDL is a compact and portable microphone distribution amplifier designed for use in broadcast and recording applications. It can be used in a studio or out in the field and can be mounted with adhesive for permanent or temporary installs. The STM-DA3 provides suitable audio quality with low self-noise. Featuring a 1.2-kOhm balanced input, the unit 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 15 dB 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. A PS-24AS (USA) 24 VDC power supply (sold separately) is required. - Sends one mic signal to three balanced outputs
- Ultra-clean audio with low self-noise and distortion
- Electrical and audio isolation
- Accepts a wide variety of microphone signals
